Phenotypic and phylogenetic characterization of a novel Lactobacillus species from human sources: description of Lactobacillus iners sp. nov. (1/2525)

Eleven strains of a hitherto undescribed Gram-positive, catalase-negative, facultatively anaerobic rod-shaped bacterium from human sources and medical care products were characterized by phenotypic and molecular taxonomic methods. The phenotypic properties of the bacterium were consistent with its assignment to the genus Lactobacillus but it was readily distinguished from all currently described species of this genus by its biochemical characteristics and by SDS-PAGE analysis of its cellular proteins. Comparative 16S rRNA gene sequence analysis demonstrated that the unknown bacterium was a member of rRNA group I Lactobacillus which includes Lactobacillus delbrueckii, the type species of the genus, and close relatives. Lactobacillus gasseri and Lactobacillus johnsonii were the nearest phylogenetic relatives of the unknown bacterium, but 16S rRNA sequence divergence values of > 4% clearly showed that it represents a distinct species. Based on both phylogenetic and phenotypic evidence, it is proposed that the unknown bacterium should be classified in the genus Lactobacillus, as Lactobacillus iners sp. nov. The type strain of Lactobacillus iners is CCUG 28746T.  (+info)

The influence of a diet rich in wheat fibre on the human faecal flora. (2/2525)

The effect on the faecal flora of adding wheat fibre to a controlled diet in four healthy volunteers for a 3-week period has been observed. No change in the concentration of the bacteria in the bacterial groups counted was found, although there was a slight increase in total output associated with increased faecal weight. The predominant organisms in all subjects were non-sporing anaerobes, but the dominant species in each subject was different and was unaffected by changing the diet. Similarly, the concentration of faecal beta-glucuronidase detected in two subjects was unaltered and the concentration of clostridia able to dehydrogenate the steroid nucleus found in one subject was unaltered. It is suggested that the faecal microflora is not primarily controlled by the presence of undigested food residues in the large bowel.  (+info)

A new hydrolase specific for taurine-conjugates of bile acids. (3/2525)

Through the investigation of the bile acid-deconjugation activities of human intestinal anaerobes, a new enzyme was discovered in Peptostreptococcus intermedius which hydrolyzed specifically the taurine-conjugates, but not the glycine-conjugates of bile acids. However, the enzymes in Streptococcus faecalis and Lactobacillus brevis hydrolyzed chiefly the glycine-conjugates.  (+info)

Temperature and pH conditions that prevail during fermentation of sausages are optimal for production of the antilisterial bacteriocin sakacin K. (4/2525)

Sakacin K is an antilisterial bacteriocin produced by Lactobacillus sake CTC 494, a strain isolated from Spanish dry fermented sausages. The biokinetics of cell growth and bacteriocin production of L. sake CTC 494 in vitro during laboratory fermentations were investigated by making use of MRS broth. The data obtained from the fermentations was used to set up a predictive model to describe the influence of the physical factors temperature and pH on microbial behavior. The model was validated successfully for all components. However, the specific bacteriocin production rate seemed to have an upper limit. Both cell growth and bacteriocin activity were very much influenced by changes in temperature and pH. The production of biomass was closely related to bacteriocin activity, indicating primary metabolite kinetics, but was not the only factor of importance. Acidity dramatically influenced both the production and the inactivation of sakacin K; the optimal pH for cell growth did not correspond to the pH for maximal sakacin K activity. Furthermore, cells grew well at 35 degrees C but no bacteriocin production could be detected at this temperature. L. sake CTC 494 shows special promise for implementation as a novel bacteriocin-producing sausage starter culture with antilisterial properties, considering the fact that the temperature and acidity conditions that prevail during the fermentation process of dry fermented sausages are optimal for the production of sakacin K.  (+info)

Cell surface-associated lipoteichoic acid acts as an adhesion factor for attachment of Lactobacillus johnsonii La1 to human enterocyte-like Caco-2 cells. (5/2525)

The influence of pH on the adhesion of two Lactobacillus strains to Caco-2 human intestinal cells was investigated. One strain, Lactobacillus johnsonii La1, was adherent at any pH between 4 and 7. The other one, L. acidophilus La10, did not attach to this cell line under the same experimental conditions. On the basis of these results, we used the monoclonal antibody technique as a tool to determine differences on the surface of these bacteria and to identify a factor for adhesion. Mice were immunized with live La1, and the hybridomas produced by fusion of spleen cells with ONS1 cells were screened for the production of antibodies specific for L. johnsonii La1. A set of these monoclonal antibodies was directed against a nonproteinaceous component of the L. johnsonii La1 surface. It was identified as lipoteichoic acid (LTA). This molecule was isolated, chemically characterized, and tested in adhesion experiments in the same system. The adhesion of L. johnsonii La1 to Caco-2 cells was inhibited in a concentration-dependent way by purified LTA as well as by L. johnsonii La1 culture supernatant that contained LTA. These results showed that the mechanism of adhesion of L. johnsonii La1 to human Caco-2 cells involves LTA.  (+info)

Binding of Cob(II)alamin to the adenosylcobalamin-dependent ribonucleotide reductase from Lactobacillus leichmannii. Identification of dimethylbenzimidazole as the axial ligand. (6/2525)

The ribonucleoside triphosphate reductase (RTPR) from Lactobacillus leichmannii catalyzes the reduction of nucleoside 5'-triphosphates to 2'-deoxynucleoside 5'-triphosphates and uses coenzyme B12, adenosylcobalamin (AdoCbl), as a cofactor. Use of a mechanism-based inhibitor, 2'-deoxy-2'-methylenecytidine 5'-triphosphate, and isotopically labeled RTPR and AdoCbl in conjunction with EPR spectroscopy has allowed identification of the lower axial ligand of cob(II)alamin when bound to RTPR. In common with the AdoCbl-dependent enzymes catalyzing irreversible heteroatom migrations and in contrast to the enzymes catalyzing reversible carbon skeleton rearrangements, the dimethylbenzimidazole moiety of the cofactor is not displaced by a protein histidine upon binding to RTPR.  (+info)

Allosteric control of three B12-dependent (class II) ribonucleotide reductases. Implications for the evolution of ribonucleotide reduction. (7/2525)

Three separate classes of ribonucleotide reductases are known, each with a distinct protein structure. One common feature of all enzymes is that a single protein generates each of the four deoxyribonucleotides. Class I and III enzymes contain an allosteric substrate specificity site capable of binding effectors (ATP or various deoxyribonucleoside triphosphates) that direct enzyme specificity. Some (but not all) enzymes contain a second allosteric site that binds only ATP or dATP. Binding of dATP to this site inhibits the activity of these enzymes. X-ray crystallography has localized the two sites within the structure of the Escherichia coli class I enzyme and identified effector-binding amino acids. Here, we have studied the regulation of three class II enzymes, one from the archaebacterium Thermoplasma acidophilum and two from eubacteria (Lactobacillus leichmannii and Thermotoga maritima). Each enzyme has an allosteric site that binds ATP or various deoxyribonucleoside triphosphates and that regulates its substrate specificity according to the same rules as for class I and III enzymes. dATP does not inhibit enzyme activity, suggesting the absence of a second active allosteric site. For the L. leichmannii and T. maritima enzymes, binding experiments also indicate the presence of only one allosteric site. Their primary sequences suggest that these enzymes lack the structural requirements for a second site. In contrast, the T. acidophilum enzyme binds dATP at two separate sites, and its sequence contains putative effector-binding amino acids for a second site. The presence of a second site without apparent physiological function leads to the hypothesis that a functional site was present early during the evolution of ribonucleotide reductases, but that its function was lost from the T. acidophilum enzyme. The other two B12 enzymes lost not only the function, but also the structural basis for the site. Also a large subgroup (Ib) of class I enzymes, but none of the investigated class III enzymes, has lost this site. This is further indirect evidence that class II and I enzymes may have arisen by divergent evolution from class III enzymes.  (+info)

Characterization of a prolidase from Lactobacillus delbrueckii subsp. bulgaricus CNRZ 397 with an unusual regulation of biosynthesis. (8/2525)

Lactobacillus delbrueckii subsp. bulgaricus CNRZ 397 (Lb. bulgaricus) is characterized by a high level of peptidase activities specific to proline-containing peptides. A prolidase (PepQ, EC 3.4.13.9) was purified to homogeneity and characterized as a strict dipeptidase active on X-Pro dipeptides, except Gly-Pro and Pro-Pro. The values for Km and Vmax were, respectively, 2.2 mM and 0.33 mmol min(-1) mg(-1), with Leu-Pro as the substrate. The enzyme exhibited optimal activity at 50 degrees C and pH 6.0, and required the presence of Zn2+. Size exclusion chromatographies and SDS-PAGE analysis led to the conclusion that this prolidase was a homodimer. Antibodies raised against the purified protein allowed the detection of PepQ among several Lactobacillus species but not lactococci. The pepQ gene and the upstream region were isolated and sequenced. The deduced peptide sequence showed that PepQ belongs to the M24 family of metallopeptidases. The pepR1 gene is located immediately upstream of pepQ and its product is homologous to the transcription factor CcpA, which is involved in catabolite repression of catabolic operons from Gram-positive bacteria. The pepR1-pepQ intergenic region contains a consensus catabolite-responsive element (CRE) which could be a target for PepR1 protein. Moreover, in contrast to other proline-specific enzymes from Lb. bulgaricus, PepQ biosynthesis was shown to be dependent on the composition of the culture medium, but not on the peptide concentration. A possible regulation mechanism is discussed.  (+info)

0043]In one exemplary embodiment, a transformed bacterial host cell with a mutant ferulic acid esterase gene is constructed. A mutant ferulic acid esterase gene is inserted into a pG+host5 vector. The mutant ferulic acid esterase gene is then transferred into bacterial host cells using electroporation. The mutant ferulic acid esterase then becomes part of the bacterial host cells genome by recombination. The bacterial host cells can be Lactobacillus buchneri cells. In some embodiments, the Lactobacillus buchneri cells will be Lactobacillus buchneri strain PTA-6138 cells. The mutant ferulic acid esterase gene can be a knock out. New strains of Lactobacillus buchneri with mutant, including knocked-out ferulic acid esterase, can be used as negative controls. For example, a transformed Lactobacillus buchneri strain can be used in an assay for studying the impact of ferulic acid esterase activity. One example of such an assay would be inoculating whole plant material, such as whole plant silage, with ...
A feeding trial was carried out effect of supplemental Lactobacillus on productivity, egg quality and intestinal microflora in 320 21 weeks - old laying hens for 12 week. Supplemented Lactobacillus strains were Lactobacillus amylovorus LLA7(LA), Lactobacillus crispatus LLA9(LC) and Lactobacillus vaginalis LLA11(LV). Three strains mixed to basal diet which containing 2,800㎉/kg ME, 16% CP with none, LA, LC, LV, LA+LC, LA+LV, LC+LV and LC+LC+LV. Supplemental level was 10(sup)7 cfu/g diet. Egg production was tended to increase with adding Lactobacilus, but not difference significantly. Average egg weight was heavier in adding Lactobacillrs compared to the none, and heaviest in LA+LV, LC+LV(P〈0.05). In periodic observation, the gap of egg weight with adding Lactobacillus or not was severe persisting laying periods. The diet containg MC or LV was better than LA, which means the difference by Lactobacillus strains for egg weight. Daily egg mass also increased in adding Lactobacillus about 1.1 to 2.3 g
Twenty morphologically different strains were chosen from French wheat sourdough isolates. Cells were Gram-positive, non-spore-forming, non-motile rods. The isolates were identified using amplified-fragment length polymorphism, randomly amplified polymorphic DNA and 16S rRNA gene sequence analysis. All isolates were members of the genus Lactobacillus. They were identified as representing Lactobacillus plantarum, Lactobacillus paralimentarius, Lactobacillus sanfranciscensis, Lactobacillus spicheri and Lactobacillus sakei. However, two isolates (LP38T and LP39) could be clearly discriminated from recognized Lactobacillus species on the basis of genotyping methods. 16S rRNA gene sequence similarity and DNA-DNA relatedness data indicate that the two strains belong to a novel Lactobacillus species, for which the name Lactobacillus hammesii is proposed. The type strain is LP38T (=DSM 16381T=CIP 108387T=TMW 1.1236T).

The mammalian gut microbiota is composed of autochthonous species that permanently colonize the host intestine, and of allochthonous species that are only transiently able to occupy the intestinal environment. In this thesis research, Lactobacillus ruminis and Lactobacillus rhamnosus GG were investigated as paradigms for each type of microbe-host interaction, with special emphasis on the in vitro characterization of their adaptation factors in the host GIT. L. rhamnosus GG has two pilus operons: spaCBA encoding the well-studied SpaCBA pili and spaFED putatively encoding SpaFED pili. The expression of SpaFED pili in L. rhamnosus GG under laboratory conditions has not thus far been reported. In this study, a nisin-induced expression system was used for the generation of SpaFED or SpaF-deleted pili in Lactococcus lactis NZ9000. The results revealed that SpaFED pili were essential in mediating lactococcal adhesion to intestinal cell lines, to certain extracellular matrix proteins, and to porcine ...

Twelve strains isolated from the posterior fornix fluid of the human vagina were identified as Lactobacillus johnsonii, Lactobacillus acidophilus, Lactobacillus gallinarum and Lactobacillus crispatus based on numerical analyses of total soluble cell protein profiles and randomly amplified polymorphic DNA (RAPD)-PCR banding patterns. Five strains grouped with the type strains of Lactobacillus gasseri (DSM 20077T) and Lactobacillus jensenii (DSM 20557T) at r | or = 0.83 in one protein profile cluster, well separated from the other species included in this study. However, numerical analysis of the RAPD-PCR banding patterns of representative strains selected from the L. gasseri-L. jensenii protein cluster clearly indicated that they belong to two different species. Four strains (TV 1010, TG 1013, TV 1018T and TV 1045) grouped into another well separated protein profile cluster at r | or = 0.87. Strains selected from this cluster displayed very similar RAPD-PCR banding patterns and clustered at R2 | or = 0

Limited information is available about homopolysaccharide synthesis in the genus Lactobacillus. Using efficient screening techniques, extracellular glucosyltransferase (GTF) enzyme activity, resulting in α-glucan synthesis from sucrose, was detected in various lactobacilli. PCR with degenerate primers based on homologous boxes of known glucosyltransferase (gtf) genes of lactic acid bacteria strains allowed cloning of fragments of 10 putative gtf genes from eight different glucan producing Lactobacillus strains (five Lactobacillus reuteri strains, one Lactobacillus fermentum strain, one Lactobacillus sake strain and one Lactobacillus parabuchneri strain). Sequence analysis revealed that these lactobacilli possess a large variation of (putative) gtf genes, similar to what has been observed for Leuconostoc and Streptococcus strains.

Background: Lactobacillus ruminis is a poorly characterized member of the Lactobacillus salivarius clade that is part of the intestinal microbiota of pigs, humans and other mammals. Its variable abundance in human and animals may be linked to historical changes over time and geographical differences in dietary intake of complex carbohydrates. Results: In this study, we investigated the ability of nine L. ruminis strains of human and bovine origin to utilize fifty carbohydrates including simple sugars, oligosaccharides, and prebiotic polysaccharides. The growth patterns were compared with metabolic pathways predicted by annotation of a high quality draft genome sequence of ATCC 25644 (human isolate) and the complete genome of ATCC 27782 (bovine isolate). All of the strains tested utilized prebiotics including fructooligosaccharides (FOS), soybean-oligosaccharides (SOS) and 1,3:1,4-b-D-glucooligosaccharides to varying degrees. Six strains isolated from humans utilized FOS-enriched inulin, as well ...
The health benefits attributed to probiotics generate interest in the search of competent strains adapted to several ecological niches, especially those related to traditional beverages and foods of each country. Pineapple tepache, a traditional Mexican fermented beverage, was used for the isolation of lactic acid bacteria with probiotic potential, one of which withstood the in vitro tests. The isolated strain AB-05, which exhibited the tested probiotic functional properties, was designated as Lactobacillus pentosus ABHEAU-05. The sequence was registered in GenBank under access code MK587617. This study is the first report of a lactic acid bacterium with in vitro digestion resistance isolated from pineapple tepache. The survival of L. pentosus ABHEAU-05 in a symbiotic medium was proven using fermented milk enriched with inulin. The in vitro digestion-resistant probiotic activity of lactobacilli was measured through analysis of pH and proteolysis. Results showed that L. pentosus grew properly in ...
A recent study suggests that taking a supplement of the probiotic Lactobacillus paracasei subsp. paracasei LP-33 may significantly improve the quality of life for people suffering from hay fever who are also taking an antihistamine. Participants in the study included 425 people with hay fever who were being treated with the antihistamine loratadine. Over the course of five weeks they were assigned either a placebo or the LP-33 supplement. Severity of hay fever was measured using the Rhinitis Quality of Life (RQLQ) global score.. At the conclusion of the study, the supplement group had significantly lower RQLQ scores when compared with the placebo. While no difference was seen in nasal symptoms, symptoms related to the eyes were significantly improved. Researchers from the French institutions Montpellier I University, University Paris Diderot, Biofortis, and Merck Consumer Health as well as Ruhr-University Bochum in Germany and the Danish institutions Copenhagen University Hospital at Gentofte ...

Vaginal probiotics or live biotherapeutic products as defined by the FDA [39] may reduce the risk of HIV transmission by: expressing antiviral factors, restoring the normal microbiota, inhibiting bacterial pathogens and modulating immuno-inflammatory responses without compromising the homeostatic environment of the host. Lactobacilli are commensal Gram-positive bacteria that widely populate the healthy female vaginal mucosa [21, 22, 40, 41]. Several Lactobacillus strains have been implicated by epidemiologic and/or experimental evidence in the maintenance of a homeostatic infection-free microenvironment most notably due to the impact of the bacterias lactic acid and H2O2 production in generating an adverse environment for HIV and other STDs. [21, 40, 42-44]. These properties may contribute to the reduction of viral particles at the site of infection [13, 45]. In contrast, a reduction in the number of Lactobacillus in the vaginal microbiota has been associated with the acquisition of bacterial ...
The research was aimed to determine the present status of probiotics (Lactobacillus spp.) and pathogenic bacteria (Vibrio spp.) of culture pond as well as to determine whether the isolated probiotic Lactobacillus spp. can act as a controlling agent on experimentally pathogenic Vibrio spp. infected Penaeus monodon. In In-vitro test of gills and intestinal tracts, the potential antagonistic activity of Lactobacillus spp. toward Vibrio spp. was gradually observed at 4th hour of probiotic treatment. At 12th hour the viable count of Vibrio spp. was drastically reduced in gill from 2.33×105 to 1.03×103 (CFUg-1) and in intestinal tract 2.35×105 to 6.43×102 (CFUg-1). While, in In-vivo test, in case of muscle, gills and intestinal tract antagonistic activity of Lactobacillus spp. toward Vibrio spp. was noticed after 9 hours, 21 hours and 27 hours respectably of probiotic injected shrimps. However, only the result of in-vitro challenge test revealed that, Lactobacillus spp. significantly reduced the ...
Fura is a millet-based spontaneously fermented dumpling produced and consumed in parts of West Africa, particularly Nigeria, Burkina Faso and Ghana. From eight traditional fura production sites in northern Ghana, 862 lactic acid bacteria were isolated and identified to species level using a combination of genotypic and phenotypic methods including (GTG)5-based PCR fingerprinting and 16S rRNA gene sequencing, multiplex PCR by means of recA gene sequence comparison, conventional morphological characteristics and carbohydrate fermentation profiling. During millet dough fermentation, pH decreased from 5.6-6.4 to 4.1-3.7 and total lactic acid bacteria (LAB) counts increased from 4.4-5.3 to 7.9-9.2 log10 (cfu/g). The initial stages of the fermentation were characterized by co-dominance of homo- and heterofermentative species of Pediococcus acidilactici, Weisella confusa, Lactobacillus fermentum, Lactobacillus reuteri, Lactobacillus salivarius, and Lactobacillus paraplantarum whereas L. fermentum was ...
The xylose cluster of Lactobacillus pentosus consists of five genes, two of which, xylAB, form an operon and code for the enzymes involved in the catabolism of xylose, while a third encodes a regulatory protein, XylR. By introduction of a multicopy plasmid carrying the xyl operator and by disruption of the chromosomal xylR gene, it was shown that L. pentosus xylR encodes a repressor. Constitutive expression of xylAB in the xylR mutant is repressed by glucose, indicating that glucose repression does not require XylR. The xylR mutant displayed a prolonged lag phase compared to wild-type bacteria when bacteria were shifted from glucose to xylose medium. Differences in the growth rate in xylose medium at different stages of growth are not correlated with differences in levels of xylAB transcription in L. pentosus wild-type or xylR mutant bacteria but are positively correlated in Lactobacillus casei with a plasmid containing xylAB. Glucose repression was further investigated with a ccpA mutant. An ...
This study aimed at evaluating non-starter lactobacilli (NSLAB) isolated from cheeses for their proteolytic activity and capability to produce fermented milk enriched in angiotensin-converting enzyme (ACE)-inhibitory and antioxidant peptides. Preliminarily, 34 NSLAB from Parmigiano Reggiano (PR) and 5 from Pecorino Siciliano cheeses were screened based on their capacity to hydrolyze milk proteins. Two NSLAB strains from PR, Lactobacillus casei PRA205 and Lactobacillus rhamnosus PRA331, showed the most proteolytic phenotype and were positively selected to inoculate sterile cow milk. The fermentation process was monitored by measuring viable cell population, kinetic of acidification, consumption of lactose, and synthesis of lactic acid. Milk fermented with Lb. casei PRA205 exhibited higher radical scavenging (1184.83 ± 40.28 mmol/L trolox equivalents) and stronger ACE-inhibitory (IC50 = 54.57 μg/mL) activities than milk fermented with Lb. rhamnosus PRA331 (939.22 ± 82.68 mmol/L trolox equivalents; IC50
Methods Clinical strains of lactobacilli were freshly isolated from urogenital tract samples of young and adolescent patients using growth on Lactobacillus MRS Agar (HiMedia) and variant of Shaedler medium. Additional differential indication media were used. Bacterial growth was studied in the presence of disc- or drop- applied of LL on solid media or LL within bacterial suspensions (0.5-5 McFarland units). Samples studied were characterized with lactobacilli at the level of 106-108 Cfu/ml, and did not contain a panel of standard bacterial and viral pathogens. Decreased contents of Staphylococcus ssp., Enterococcus ssp., E. coli, and Candida ssp. were registered.. ...
The aim of this study is to establish the microbiological stability of traditionally fermented permanent sausages of domestic pig and wild boar meat mixtures. A sausage production mixture was inoculated with the strain Lactobacillus curvatus MRS_532 which has shown a good technological potential in the previous studies and is selected for use as a starter culture. During fermentation and ripening the sausage was followed by survival of the inoculated strain, as well as its influence on the microbiological composition of sausages, compared to the uninoculated control. The pH value was determined by a significant difference in the pH value of the inoculated sausage after 7. (p ,0,001) and 40 days (p ,0,05) compared to uninoculated sausage. The number of lactobacilli in inoculated sausage was significantly higher than the number of lactobacilli in the control sausage during all phases (p ,0,05), while the number of unwanted microbial generally fell towards the end of ripening. Based on the analysis ...

Widespread use of antibiotics in the intensive care unit is a potential cause of the emergence of hospital-acquired pneumonia. This study determined whether Lactobacillus salivarius feeding could reverse antibiotic-induced lung defense impairment in a ventilator model. C57BL/6 wild-type (WT) mice received mechanical ventilation for 3 h after intramuscular antibiotic treatment for 6 days. Treatment with dead Lactobacillus salivarius and fructo-oligosaccharides (FOS) feeding were used to stimulate antibacterial protein expression in the intestine. Reactive oxygen species (ROS) in the intestinal mucosa was detected using 2ʹ7ʹ-dichlorofluorescein diacetate. The peroxynitrite production of alveolar macrophages (AMs) was measured using dihydrorhodamine 123 oxidation assay. N-acetylcysteine (NAC), an ROS scavenger, was orally administered to mice receiving antibiotics with FOS feeding. Antibiotic treatment decreased Pseudomonas aeruginosa (PA) phagocytic activity and activity of AMs and protein expression of
Cereal grains are often included in equine diets. When starch intake exceeds foregut digestion starch will reach the hindgut, impacting microbial ecology. Probiotics (e.g., lactobacilli) are reported to mitigate GI dysbioses in other species. This study was conducted to determine the effect of exogenous lactobacilli on pH and the growth of amylolytic and lactate-utilizing bacteria. Feces were collected from 3 mature geldings fed grass hay with access to pasture. Fecal microbes were harvested by differential centrifugation, washed, and re-suspended in anaerobic media containing ground corn, wheat, or oats at 1.6% (w/v) starch and one of five treatments: Control (substrate only), L. acidophilus, L. buchneri, L. reuteri, or an equal mixture of all three (107 cells/mL, final concentration). After 24 h of incubation (37°C, 160 rpm), samples were collected for pH and enumerations of total amylolytics, Group D Gram-positive cocci (GPC; Enterococci, Streptococci), lactobacilli, and lactate-utilizing bacteria.

Scanning electron micrograph (SEM) of Lactobacillus buchneri, Gram-positive, non-spore forming, anaerobic or microaerophilic, rod prokaryote. This bacterium is a heterofermentative bacterium that produces lactic acid and acetic acid during fermentation. When silages are exposed to air, yeasts can degrade lactic acid, which increases the pH and leads to spoiling. L. buchneri is used as a bacterial inoculant to improve the aerobic stability of silage (grass silage, legume silage and grain silage, high moisture grains). L. buchneri is a heterolactic microbe that produces high concentrations of acetic acid, and sometimes lesser amounts of 1, 2 propanediol, propanol, and propionic acid. Both acetic acid and propionic acid are more effective at reducing the growth of yeasts and molds than is lactic acid during silage storage.

Vaginal lactic acid bacteria defend the host against pathogens through a combination of competitive exclusion, competition for nutrients, production of antimicrobial substances and through the activation of the immune system. A new human isolate named Lactobacillus crispatus L1 was characterized in this work, and a preliminary evaluation of its probiotic potential is described together with a process to obtain a high productivity of viable biomass. In a simulated digestion process 1.8⋅1010 cells∙ml−1 survived the gastric environment with 80% viability, without being affected by small intestine juices. Experiments on six different C sources were performed to analyze growth and organic acids production and, glucose, provided the best performances. A microfiltration strategy was exploited to improve the cellular yield in 2 L-fermentation processes, reaching 27 g · l−1 of dry biomass. Moreover, L. crispatus L1 demonstrated a greater stability to high concentrations of lactic acid, compared to other
This study aimed to assess the antibiotic susceptibility of Lactobacillus strains of goat milk origin. Lactobacilli are generally recognized as safe, but can act as reservoir for genes carrying antibiotic resistance traits; which can further spread to commensal, food spoilage or pathogenic organisms. Lactic acid bacteria (LAB) strains coming from animal sources had significant interaction with antibiotics. Goat milk, being second to cow milk in production and due to its close resemblance to human milk composition, is among favorable source for isolating potential probiotic LAB strains. Herein, this study assessed the antibiotic susceptibility pattern of fourteen Lactobacillus strains isolated from goat milk. The antibiotic susceptibility was recorded against thirty antibiotics following standard disk-diffusion assay. Imipenem, meropenem and nitrofurantoin turned out to be the most effective antibiotics, displaying high zone of inhibition (ZOI) against all the isolates. In contrast, all
A prospective, placebo-controlled, triple blind clinical trial was carried out in Pakistan to determine the effect of Lactobacillus GG on the course of acute diarrhea in hospitalized children. Forty children (mean age, 13 months) were enrolled and after rehydration received either oral Lactobacillus GG (n = 21) or placebo (n = 19) twice daily for 2 days, in addition to the usual diet. The clinical course of diarrhea was followed during the treatment period. Features on admission into the study groups were similar and were characterized by severe diarrhea, malnutrition and inappropriate management before presentation. Response was evident on Day 2 when the frequency of both vomiting and diarrhea was less in the Lactobacillus group. In those who had presented with acute nonbloody diarrhea (n = 32), the percentage of children with persistent watery diarrhea at 48 hours was significantly less in the Lactobacillus group: 31% vs. 75% (P | 0.01). No significant difference was observed by 48 hours in those
Adherence is a critical first step in the infection of a new host for many pathogens, including N. gonorrhoeae. As incoming pathogens, gonococci have to overcome the hosts defenses and compete with the indigenous microbiota to effectively colonize the endocervical epithelia. L. jensenii, one of the bacterial species most commonly isolated from the healthy human vaginal tract, has been shown to inhibit gonococcal adherence to and invasion of epithelial cells using a coculture model of infection (38). The inhibition of gonococcal adherence was not caused by any secreted factor, such as hydrogen peroxide, by coaggregation of the gonococci and the lactobacilli, or by competition for receptors. The ability to inhibit gonococcal adherence without direct killing of the pathogen might be specific to Lactobacillus species, as we found no inhibition of adherence when cells were pretreated with another Gram-positive bacterium, B. subtilis. This finding correlates with research which showed that vaginal ...

Ubiquinone (UQ), also called coenzyme Q, and plastoquinone (PQ) are electron carriers in oxidative phosphorylation and photosynthesis, respectively. The quinoid nucleus of ubiquinone is derived from the shikimate pathway; 4-hydroxybenzoate is directly formed from chorismate in bacteria, while it can be formed from either chorismate or tyrosine in yeast. The following biosynthesis of terpenoid moiety involves reactions of prenylation, decarboxylation, and three hydroxylations alternating with three methylations. The order of these reactions are somewhat different between bacteria and yeast. Phylloquinone (vitamin K1), menaquinone (vitamin K2), and tocopherol (vitamin E) are fat-soluble vitamins. Phylloquinone is a compound present in all photosynthetic plants serving as a cofactor for photosystem I-mediated electron transport. Menaquinone is an obligatory component of the electron-transfer pathway in bacteria ...

Lactobacillus species administered in combination with other probiotics benefits cases of irritable bowel syndrome (IBS), although the extent of efficacy is still uncertain.[25] The probiotics help treat IBS by returning homeostasis when the gut microbiota experiences unusually high levels of opportunistic bacteria.[6] In addition, Lactobacillus species can be administered as probiotics during cases of infection by the ulcer-causing bacterium Helicobacter pylori.[26] Helicobacter pylori is linked to cancer, and antibiotic resistance impedes the success of current antibiotic-based eradication treatments.[26] When Lactobacillus probiotics are administered along with the treatment as an adjuvant, its efficacy is substantially increased and side effects may be lessened.[26] Also, Lactobacillus is used to help control urogenital and vaginal infections, such as bacterial vaginosis (BV). Lactobacillus produce bacteriocins to suppress pathogenic growth of certain bacteria,[27] as well as lactic acid and ...
The genus Lactobacillus belongs to a large heterogeneous group of low G + C Gram-positive anaerobic bacteria, which are frequently used as probiotics. The health-beneficial effects, in particular the immunomodulation effect, of probiotics depend on the strain and dose used. Strain variations may be related to diversity of the cell surface architecture of bacteria and the ability to express specific antigens or secrete compounds. The use of Lactobacillus as probiotic requires a comprehensive understanding of its effect on host immune system. To evaluate the potential immunoreactive properties of proteins isolated from four Lactobacillus strains: L. johnsonii 142 and L. johnsonii 151, L. rhamnosus LOCK 0900 and L. casei LOCK 0919, the polyclonal sera obtained from mouse and human have been tested as well as with sera from rabbits immunized with whole lactobacilli cells. The reactivity of isolated proteins detected by SDS-PAGE and Western blotting was heterogeneous and varied between different serum
Lactobacillus isolates from healthy Estonian and Swedish children were characterised by a lectin typing technique; 56 isolates from six species (L. acidophilus, L. paracasei, L. plantarum, L. fermentum, L. brevis and L. buchneri) were tested. The typing system was based on an agglutination assay with a panel of six commercially available lectins, which,were chosen on the basis of their carbohydrate specificities. The isolates were also subjected to proteolytic degradation before lectin typing to decrease auto-agglutination of whole cells in the assay. The 56 isolates were divided into 15 different lectin types by their lectin agglutination patterns. Proteolytic treatment reduced auto-agglutination for the majority of species, apart from L. acidophilus, which remained predominantly auto-agglutinating (eight of nine strains). The system produced stable and reproducible results under standardised culture conditions. Lactobacilli are important bacteria for use as probiotics and this system may ...

Three Lactic Acid Bacteria (LAB) namely Lactobacillus plantarum, Lactobacillus pentosus and Lactococcus lactis lactis were isolated from un-pasteurized camel milk that was allowed to ferment spontaneously for one week. The probiotic potential of these isolates was investigated using in vitro antagonistic tests against Salmonella typhimurium ATCC 14028, Salmonella enteritidis ATCC 13076, E. coli 8739 strain, Staphylococcus epidermis and Staphylococcus capitis. The isolated LAB bacteria resisted the bactericidal effect of each other and did not produce antagonistic effect against Staphylococcus sp. However, Lactobacillus plantarum was able to inhibit the growth of the Gram negative tested bacteria with an average inhibition zone of 18 and 26 mm in diameter against Salmonella sp. and E. coli strains, respectively, while, Lactobacillus pentosus produced an average inhibition zone of 15 mm against Salmonella sp. and 25 mm against E. coli strains. Lactococcus lactis lactis antagonistic behavior was ...

Administration of probiotic Lactobacillus spp. before irradiation results in decreased epithelial apoptosis and increased crypt survival in the mouse small intestine. In this study, the greatest protection was offered by administration of LGG, although gavage with other Lactobacillus spp. or LGG-CM also showed significant benefit. Administration of a Bifidobacterium sp. was not radioprotective in this model. The radioprotective effects mediated by LGG required intact signalling of TLR-2, MyD88 and COX-2. LGG was protective when given before, but not after, radiation, suggesting that LGG acts by preventing radiation-induced injury rather than enhancing repair.. Peptidoglycan and lipoteichoic acid, components of the cell wall of Gram-positive bacteria including LGG, are TLR-2 ligands. The finding that LGG-CM is also radioprotective suggests that LGG peptidoglycan or lipoteichoic acid is released into the medium and is capable of binding TLR-2. This is the first demonstration that a probiotic-based ...
