In South Africa malnutrition exists due to inadequate dietary intake of micronutrients which is one of the major causes of vitamin deficiencies leading to disease. The treatment of malnutrition over the past years has been a considerable burden on the South African economy. Therefore, food fortification is one of the current strategies used to minimize malnutrition by increasing the nutritional value of staple foods. Commercial dairy products and pharmaceutical nutritional products (food supplements) in South Africa have been developed and produced for affluent consumers. Hence the need to develop an affordable fortified dairy product for the majority of South Africans prompted this study aimed at using a "naturally" fortified kefir beverage with vitamin B12 and folate to increase B-vitamins levels. Since Propionibacterium freudenreichii and Streptococcus thermophilus are known to be good producers of vitamin B12 and folate, respectively, and propionibacteria has the ability to grow ...
Its members are primarily facultative parasites and commensals of humans and other animals, living in and around the sweat glands, sebaceous glands, and other areas of the skin. They are virtually ubiquitous and do not cause problems for most people, but propionibacteria have been implicated in acne and other skin conditions.[5] One study found the Propionibacterium was the most prevalent human skin-associated genus of microorganisms.[6]. Members of the genus Propionibacterium are widely used in the production of vitamin B12, tetrapyrrole compounds, and propionic acid, as well as in the probiotics and cheese industries.[7]. The strain Propionibacterium freudenreichii subsp. shermanii is used in cheesemaking to create CO2 bubbles that become "eyes"-round holes in the cheese.[8]. ...

There have been contradicting reports of the efficacy of direct-fed microbials in finishing cattle diets. Some researchers have observed improvements in daily gain and feed efficiency when direct-fed microbials are included in finishing diets, whereas others have reported no differences in dry matter intake or ruminal and blood pH. Many of these studies have been conducted on a relatively small scale and used few animals per pen compared with that of typical commercial feedlot operations. In our study, yearling crossbred beef steers and heifers (n=3,539; 796 lb body weight) were used in an experiment conducted at a commercial feedlot operation to characterize growth performance and carcass characteristics associated with the supplementation of direct-fed microbials (Lactobacillus acidophilus and Propionibacterium freudenreichii) in finishing cattle diets. Including direct-fed microbials in the diet throughout a 122-day finishing period had no measurable impact on growth performance or carcass ...
Fifteen strains of propionibacteria, isolated from dairy products, were screened for the production of bacteriocins. Propionibacterium thoenii 447 produced an antimicrobial peptide, thoeniicin 447, which acted bactericidal against Lactobacillus delbrueckii subsp. bulgaricus and bacteriostatic against Propionibacterium acnes. Thoeniicin 447 remained active after 15 min at 100°C and after 30 min of incubation at pH 1-10. The peptide was inactivated when treated with pepsin, pronase, α-chymotrypsin, trypsin and proteinase K. Optimal bacteriocin production was detected during late exponential growth. The peptide was partially purified by ammonium sulfate precipitation, followed by SP-Sepharose cation exchange chromatography. The estimated size of thoeniicin 447, according to tricine-SDS-PAGE, is 6 kDa. Based on DNA sequencing, the mature peptide is 7130.20 Da in size and homologous to propionicin T1, produced by P. thoenii strain 419 (=NCFB 568T). Strain 447 is phenotypically different from strain ...

Kinetic studies were performed on the superoxide dismutases isolated from the anaerobic bacterium Propionibacterium shermanii as active enzymes with either iron or manganese, which were naturally incorporated into the same molecule depending on the metal supply. Both the Fe- and Mn- forms showed decreasing activity with increasing pH. This suggests the protonation of some groups near the metal, possibly a metal-bound water molecule. Thus the kinetic behaviour of this superoxide dismutase is much more dependent on the protein structure than on the metal incorporated into the active site. The secondary structures of both forms were not influenced by variations in pH, whereas the EPR spectra of the Fe-superoxide dismutase changed as a function of pH. The EPR spectra apparently consist of two overlapping species. Steady-state experiments proved that all iron-containing species show catalytic activity, but the species predominating in the alkaline pH range displays a lower reaction rate. The ...

The genetic basis of erythromycin resistance in cutaneous propionibacteria was determined by comparing the nucleotide sequences of the peptidyl transferase region in the 23S rRNAs from 9 susceptible and 26 resistant clinical isolates as well as 4 laboratory-selected erythromycin-resistant mutants of a susceptible strain. In 13 isolates and the 4 laboratory mutants, cross-resistance to macrolides, lincosamides, and B-type streptogramins was associated with an A--,G transition at a position cognate with Escherichia coli 23S rRNA base 2058. These strains were resistant to , or = 512 microg of erythromycin per ml. Two other mutations were identified, an A--,G transition at base 2059 in seven strains, associated with high-level resistance to all macrolides, and a G--,A transition at base 2057 in six strains, associated with low-level resistance to erythromycin. These mutations correspond to three of four phenotypic classes previously identified by using MIC determinations. ...
One of the least controlled defects in Swiss cheese is development of splits that appear during refrigerated storage after cheese is removed from the warm room. Such fissures, or cracks, in the body of the cheese can be as short as 1 cm, or long enough to span a 90-kg block. A 2 × 2 × 2 factorial experiment was used to determine the effect of different Lactobacillus helveticus/Propionibacterium freudenreichii ssp. shermanii starter culture combinations on the occurrence of split defect in Swiss cheese. Eights vats of cheese were made in summer and eight in winter. Each 90-kg block of cheese was cut into twenty-four 4-kg blocks and graded based on the presence of splits. Only small variations were found in the composition of cheeses made during the same season. There were no correlations between moisture, pH, fat, protein, calcium, lactose contents, D/L lactate ratio, or protein degradation that could be used to predict splits after 90 d of storage. However, cheese made in the summer had 2% higher

Recently, there has been increasing interest to use probiotic bacteria as an alternative to conventional antibiotics in controlling pathogens in animal agriculture, including poultry. Probiotics are live microorganisms that if administered in adequate quantity result in desired health benefits in the host, including reduction of pathogenic bacteria. Several probiotic bacteria, including Lactobacillus spp., Bacillus spp., Bifidobacterium, and Pediococcus have been used in the poultry industry, either individually or in combination. Propionibacterium freudenreichii, the focus of this study, has proven probiotic properties and is commonly present in fermented dairy products such as cheese ...
Lactobacillus pentosus TV35b, isolated from the posterior fornix secretions of the vagina of a prenatal patient, produced a bacteriocin-like peptide (pentocin TV35b), which is inhibitory to Clostridium sporogenes, Cl. tyrobutyricum, Lact. curvatus, Lact. fermentum, Lact. sake, Listeria innocua, Propionibacterium acidipropionici, Propionibacterium sp. and Candida albicans. The mechanism of activity of pentocin TV35b is bactericidal, as shown by a decrease in the viable cell numbers of Lact. sake from approximately 4 x 108 to less than 10 cfu ml-1 over a period of 4 h. Pentocin TV35b added to the growth medium of C. albicans stimulated the formation of pseudohyphae during the first 36 h, followed by a slight repression in cell growth. Production of pentocin TV35b was at its maximum towards the end of the logarithmic growth phase of strain TV35b. The peptide was purified by ammonium sulphate precipitation, followed by SP-Sepharose cation exchange chromatography. The molecular size of pentocin TV35b ...
Propionibacterium species are nonsporulating, gram-positive anaerobic bacilli that are considered commensal bacteria on the skin. They are usually nonpathogenic and are common contaminants of blood and body fluid cultures.
Consumption of human breast milk (HBM) attenuates the incidence of necrotizing enterocolitis (NEC), which remains a leading and intractable cause of mortality in preterm infants. Here, we report that this diminution correlates with alterations in the gut microbiota, particularly enrichment of Propionibacterium species. Transfaunation of microbiota from HBM-fed preterm infants or a newly identified and cultured Propionibacterium strain, P. UF1, to germfree mice conferred protection against pathogen infection and correlated with profound increases in intestinal Th17 cells. The induction of Th17 cells was dependent on bacterial dihydrolipoamide acetyltransferase (DlaT), a major protein expressed on the P. UF1 surface layer (S-layer). Binding of P. UF1 to its cognate receptor, SIGNR1, on dendritic cells resulted in the regulation of intestinal phagocytes. Importantly, transfer of P. UF1 profoundly mitigated induced NEC-like injury in neonatal mice. Together, these results mechanistically elucidate ...

Harland Goff Wood was born in Delavan, Minnesota, and attended Macalester College, where he majored in chemistry. He obtained his Ph.D. in 1935 from Iowa State College, working with Chester Werkman on fermentation by propionic acid bacteria. With Werkman, Wood discovered that the products of glycerol fermentation contained more carbon than was supplied by the fermented glycerol. He subsequently found that the extra carbon was derived from CO2 in the buffer. He proposed that CO2 and pyruvate combine to form oxaloacetate, which is then reduced to succinate. This became known as the Wood-Werkman reaction. After earning his Ph.D., Wood went to the University of Wisconsin, where he worked as a postdoctoral fellow with W. H. Petersen studying the growth factor requirements for propionic acid bacteria. He returned to Iowa State in 1936 as an assistant research professor and continued to work on CO2 fixation, concluding that carbon dioxide is fixed by a union of three-carbon and one-carbon ...

TY - JOUR. T1 - Interleukin-12 regulates natural killer cell-dependent Propionibacterium acnes-primed, lipopolysaccharide-induced liver injury. AU - Margenthaler, Julie A.. AU - Ku, Grace. AU - Flye, M. Wayne. PY - 2008/2/1. Y1 - 2008/2/1. N2 - Aim: Interleukin (IL)-12, produced primarily by macrophage/monocytes, modulates mature T and natural killer (NK) cell functions, including cytotoxicity and cytokine production. Methods: To determine the role ofIL-12 in Propionibacterium acnes (P. acnes)-primed, lipopolysaccharide (LPS)-induced liver injury, mice were injected with an anti-IL-12 monoclonal antibody (mAb) 1 and 2 days before P. acnes injection (day 0) or 5 and 6days before LPS challenge (day 7). The survival rates, plasma cytokine levels, and liver mononuclear cell phenotypes were evaluated for the mice treated with and without anti-IL-12 mAb. Results: The observed mortality with P. acnes-primed, LPS-induced liver injury in C57BL/6 (B6) mice was 100%, but was reduced to 0% in interferon ...
Propionic acid fermentation is carried out by several bacteria that belong to the genus Propionibacterium and to the species Clostridium propionicum. During propionic acid fermentation, both sugar and lactate can be used as the initial substrate. When sugar is available, these bacteria use the EMP pathway to produce pyruvate; the pyruvate is carboxylated to oxalacetate by methyl malonyl coen-zyme-A (CoA) and then reduced to propionate via malate, fumarate, and succinate. The other end products of propionic fermentation are acetic acid and CO2 (Figure 3). In particular, the propionic acid fermentation of 3 mol of glucose produces 4 mol of propionic acid, 2 mol of acetic acid, 2 mol of CO2, and 12 mol of ATP. When lactate is the initial substrate, propionic fermentation results in the production of 2 mol of propionic acid, 1 mol of acetic acid, and 1 mol of CO2. In this process, 1 mol of ATP is generated per nine carbons, and because of this, propionic bacteria generally grow very slowly.. The ...
Propionibacterium acnes is a member of the resident cutaneous flora. Sebaceous follicles involved in acne are characterized by the accumulation of abnormally desquamated corneocytes and excess sebum-the microcomedo. This environment provides ideal growth conditions for P acnes. Several orders of magnitude level of P acnes are found in microcomedos. P acnes produces a variety of chemotactic factors and proinflammatory molecules that are responsible for the inflammatory phase of acne. Antibiotic therapy works by reducing the viable number of P acnes as well as by reducing the production of inflammatory stimuli. Antibiotic therapy has been a mainstay of treatment for more than 30 years. In the last decade, decreased sensitivity to antibiotics has developed and clinical resistance has been described. This development threatens the usefulness of antibiotic therapy in the future.
Propionibacterium acnes, an anaerobic, gram-positive bacillus, is known to be one of the most frequent causes of postsurgical endophthalmitis. Direct intravitreal antibiotic instillation has been shown to be safe and effective for the treatment of many aerobic organisms (8, 9, 11). Optimal treatment of P. acnes, which has been shown to cause a chronic, indolent infection after cataract surgery and lens implantation despite intravitreal vancomycin instillation, vitrectomy, and removal and exchange of the intraocular lens, remains unknown (2, 4). Despite recent research indicating the susceptibility of P. acnes to older beta-lactams, fluoroquinolones, and macrolides, in vivo success with antibiotics that are currently available for intravitreal instillation has been inconsistent, and additional antibiotic alternatives are needed (6, 10).. In the present study, the in vitro susceptibilities of P. acnes ophthalmic isolates to two of the newer carbapenems, ertapenem and meropenem, and the ...

The significance of fermentation in the large gut of the dog has been investigated. According to the quantities of volatile acids and their relation to body weight, the lower fatty acids do not appear to contribute more than a small portion of the energy requirements of the animal. Evidence is presented to show that the individual acids produced in the large intestine consist largely of acetic and propionic acids and that the amount of butyric present is small. This is the same mixture of acids found where fermentation occurs in the alimentary tract of ruminants, horses, pigs, rabbits and rats. The higher proportion of propionic acid is interesting and suggests that the propionic acid bacteria are normal inhabitants of the large intestine of the dog and possibly of a wide variety of animals. ...

This necessity for prolonged contact may prove to be important for macrophage activation. This is suggested by comparing the prolonged effects in vivo of injection of casein, on the one hand, and C. parvum or other anaerobic coryneforms on the other. Both have short-term stimulating effects on macrophages. Both casein and C. parvum are chemotactic for macrophages and both induce a macrophage exudate 2-5 days after injection into the peritoneal cavity of the guinea-pig (49). However after casein-induction, these macrophages disappear from the peritoneal cavity soon afterwards. The relevance of this mechanism to the microbicidal effect of activated macrophages is not known, especially since mature macrophages, at least in the mouse, are thought to be relatively poor in peroxidase activity (25). 2. Nonmicrobial Targets Activated macrophages appear to kill tumor cells by a nonphagocytic mechanism. Several authors have emphasized the need for a close contact between activated macrophages and target ...
Zits, pimples, blemishes, breakouts-whatever you call it, acne can be a tough condition that can be challenging to treat. Acne is very typical, with an estimated 80% of all individuals worldwide expected to suffer from some sort of acne in their life time.. Most people who suffer from acne turn to extreme chemicals and standard antibiotic treatments to recover from the results of acne. More choices are available now than ever in the past. If you are thinking about seeking out alternative therapies, here is a quick run-down of the most recent techniques for treating acne.. Blue light treatment: this therapy is aimed at acne clients who have had little success with other treatments. Blue light treatment concentrates on eliminating the germs that triggers most kinds of acne, Propionibacterium acnes (P. acnes). P. Acnes produces the small particles referred to as porphyrins that in turn help produce the germs that triggers most kinds of acne inflammation. Blue light treatment works by zeroing in on ...
