Quantitative studies on competitive activities of skin bacteria growing on solid media. (1/570)

Earlier quantitative investigations of antagonism between skin bacteria were based on the use of liquid cultures, but a more realistic model has now been devised, based on the use of the surfaces of solid media. Pure or mixed inocula were spread evenly over suitable agar media in Petri dishes marked out with a standard grid. Growth curves were constructed from viable counts of the surface bacteria after they had been removed from excised squares of the agar media and dispersed. The method was highly reproducible, and competitive interactions were revealed more clearly than in studies with liquid media. An antibiotic-producing strain of Staphylococcus epidermidis (S6+) readily suppressed strains of Micrococcus, Corynebacterium and Streptococcus species. However, a Staphylococcus aureus strain which was less sensitive to the antibiotic effect of S6+ interacted in a complex manner, depending on the absolute and relative size of the S6+ inoculum.  (+info)

Secretion of FK506/FK520 and rapamycin by Streptomyces inhibits the growth of competing Saccharomyces cerevisiae and Cryptococcus neoformans. (2/570)

FK506 and rapamycin are immunosuppressants that inhibit signalling cascades required for T-cell activation, yet both are natural products of Streptomyces that live in the soil. FK506 and rapamycin also have potent antimicrobial activity against yeast and pathogenic fungi, suggesting a natural role in inhibiting growth of competing micro-organisms. The immunosuppressive and antimicrobial activities of FK506 and rapamycin are mediated by binding to the FKBP12 prolyl isomerase and the resulting FKBP12/FK506 and FKBP12/rapamycin complexes inhibit conserved protein targets, either the phosphatase calcineurin or the TOR (target of rapamycin) kinases, respectively. Streptomyces sp., 'Streptomyces hygroscopicus subsp. ascomyceticus' and Streptomyces hygroscopicus, which produce FK506, FK520 (also known as ascomycin, a C21 ethyl derivative of FK506) and rapamycin, respectively, produced toxins that inhibited the growth of competing cells of the yeast Saccharomyces cerevisiae and the pathogenic fungus Cryptococcus neoformans. Yeast and fungal mutants lacking FKBP12 or expressing dominant drug-resistant calcineurin or TOR mutants were resistant to FK506 and rapamycin, and to the toxins produced by Streptomyces. Streptomyces strains with mutations in the FK506 or rapamycin biosynthetic enzymes were impaired in toxin production. Finally, the toxins secreted by 'S. hygroscopicus subsp. ascomyceticus' and S. hygroscopicus promoted formation of FKBP12/calcineurin and FKBP12/TOR complexes in a two-hybrid assay and mutations that rendered calcineurin or TOR drug-resistant prevented interaction. These observations support the hypothesis that Streptomyces evolved to secrete FK506, FK520 and rapamycin as toxins to inhibit the growth of competing yeast and fungi.  (+info)

Purification and properties of a basic endo-beta-1,6-glucanase (BGN16.1) from the antagonistic fungus Trichoderma harzianum. (3/570)

The antagonistic fungus Trichoderma harzianum CECT 2413 produces at least two extracellular beta-1,6-glucanases, among other hydrolases acting on polysaccharides from fungal cell walls, when grown in chitin as the sole carbon source. We have previously reported on the purification and biochemical characterization of the major activity, which corresponds to an acidic enzyme named BGN16.2 [de la Cruz, J., Pintor-Toro, J.A., Benitez, T. & Llobell, A. (1995) J. Bacteriol. 177, 1864-1871]. In this paper, we report on the purification to electrophoretical homogeneity of BGN16.1, the second beta-1, 6-glucanase enzyme. BGN16.1 was purified by ammonium sulfate precipitation followed by adsorption and digestion of pustulan (a beta-1,6-glucan), chromatofocusing and gel-filtration chromatography. BGN16.1 is a non-glycosylated protein with an apparent molecular mass of 51 kDa and a basic isoelectric point (pI 7.4-7.7). The enzyme was active toward substrates containing beta-1,6-glycosidic linkages, including yeast cell walls. The Km was 0.8 mg x mL-1 with pustulan as the substrate. Reaction product analysis by HPLC clearly indicated that BGN16.1 has an endo-hydrolytic mode of action. The probable role of this enzyme in the antagonistic action of T. harzianum is also discussed.  (+info)

Intestinal colonisation of gnotobiotic pigs by Salmonella organisms: interaction between isogenic and unrelated strains. (4/570)

The effect of intestinal colonisation by a Salmonella strain on the establishment in the gut of an isogenic mutant administered orally 24 h after the first strain was studied in gnotobiotic pigs. Irrespective of the clinical outcome of the infection, the extensive colonisation of one Salmonella strain prevented a similar degree of colonisation by an otherwise isogenic antibiotic resistant strain; in some cases the second strain was hardly detectable. The poor colonisation of the challenge Salmonella strains was generally reflected in very low counts of organisms in the tissues. Colonisation by a strain of Escherichia coli reduced the rate of establishment of an isogenic E. coli, strain but did not prevent colonisation by an S. Typhimurium strain. S. Typhimurium with mutations in the tsr (serine chemotaxis receptor protein) or oxrA (transcriptional regulator of anaerobic metabolism) genes did not inhibit colonisation. Mutations in cya (adenylate cyclase), tar and trg (chemotaxis receptor proteins for aspartate and ribose respectively) genes were less inhibitory, while motB (non-motile) and cheR (impaired motility) mutants were fully inhibitory.  (+info)

A new alkaline pH-adjusted medium enhances detection of beta-hemolytic streptococci by minimizing bacterial interference due to Streptococcus salivarius. (5/570)

A new selective medium (CNA-P) that reduces or eliminates the inhibitory activity of bacteriocin-producing Streptococcus salivarius against beta-hemolytic streptococci has been developed and compared with sheep blood agar (SBA) for the sensitive detection of small numbers of beta-hemolytic streptococci in clinical specimens. CNA-P has as its basis a commercial medium (Difco Columbia CNA agar) supplemented with 5% (vol/vol) sheep blood, and the CNA is further modified by addition of 100 mM PIPES buffer [piperazine-N,N'-bis(2-ethanesulfonic acid)] (pH 7.5) to maintain cultures at an alkaline pH during incubation. CNA-P was shown to inhibit the production and/or release of four different types of S. salivarius bacteriocins or bacteriocin-like inhibitory molecules. The efficacies of CNA-P and SBA for detection of beta-hemolytic streptococci in 1,352 pharyngeal samples from 376 children were compared. The beta-hemolytic streptococcal isolates recovered from the samples included 314 group A (S. pyogenes), 61 group G, 33 group B, and 5 group C streptococci. Of 314 samples that yielded S. pyogenes, 300 were positive on CNA-P (96%) and 264 (86%) were positive on SBA. A significantly greater number of S. pyogenes isolates from these samples were recovered only on CNA-P (50 of 314) compared with the number of isolates recovered only on SBA (14 of 314). In addition, the degree of positivity, a measure of the total numbers of S. pyogenes isolates on the plate, was significantly higher on CNA-P than on SBA (2.40 versus 2.07; P < 0.001). Interestingly, CNA-P was also found to enhance the hemolytic activity of streptolysin O, allowing detection of streptolysin S-deficient S. pyogenes strains which might otherwise go undetected on SBA and other isolation media.  (+info)

Selected bacterial strains protect Artemia spp. from the pathogenic effects of Vibrio proteolyticus CW8T2. (6/570)

In this study Vibrio proteolyticus CW8T2 has been identified as a virulent pathogen for Artemia spp. Its infection route has been visualized with transmission electron microscopy. The pathogen affected microvilli and gut epithelial cells, disrupted epithelial cell junctions, and reached the body cavity, where it devastated cells and tissues. In vivo antagonism tests showed that preemptive colonization of the culture water with nine selected bacterial strains protected Artemia juveniles against the pathogenic effects. Two categories of the selected strains could be distinguished: (i) strains providing total protection, as no mortality occurred 2 days after the experimental infection with V. proteolyticus CW8T2, with strain LVS8 as a representative, and (ii) strains providing partial protection, as significant but not total mortality was observed, with strain LVS2 as a representative. The growth of V. proteolyticus CW8T2 in the culture medium was slowed down in the presence of strains LVS2 and LVS8, but growth suppression was distinctly higher with LVS8 than with LVS2. It was striking that the strains that gave only partial protection against the pathogen in the in vivo antagonism test showed also a restricted capability to colonize the Artemia compared to the strains providing total protection. The in vivo antagonism tests and the filtrate experiments showed that probably no extracellular bacterial compounds were involved in the protective action but that the living cells were required to protect Artemia against V. proteolyticus CW8T2.  (+info)

Antagonistic activity of Lactobacillus acidophilus LB against intracellular Salmonella enterica serovar Typhimurium infecting human enterocyte-like Caco-2/TC-7 cells. (7/570)

To gain further insight into the mechanism by which lactobacilli develop antimicrobial activity, we have examined how Lactobacillus acidophilus LB inhibits the promoted cellular injuries and intracellular lifestyle of Salmonella enterica serovar Typhimurium SL1344 infecting the cultured, fully differentiated human intestinal cell line Caco-2/TC-7. We showed that the spent culture supernatant of strain LB (LB-SCS) decreases the number of apical serovar Typhimurium-induced F-actin rearrangements in infected cells. LB-SCS treatment efficiently decreased transcellular passage of S. enterica serovar Typhimurium. Moreover, LB-SCS treatment inhibited intracellular growth of serovar Typhimurium, since treated intracellular bacteria displayed a small, rounded morphology resembling that of resting bacteria. We also showed that LB-SCS treatment inhibits adhesion-dependent serovar Typhimurium-induced interleukin-8 production.  (+info)

The role of normal flora in Giardia lamblia infections in mice. (8/570)

The presence of normal bacterial flora in the intestinal tract is thought to protect against colonization by pathogens. Only a few specific examples of this protection have been demonstrated for bacterial pathogens and protozoan infections. Mice from one commercial breeding farm were found to be less susceptible to infection with Giardia lamblia than were isogenic mice from another facility. When mice were housed together, resistance to infection was readily transferred to normally susceptible mice. After resistant mice were treated with neomycin, differences in susceptibility to infection were shown to be due to differences in the resident flora present in these mice. These results suggest the possible use of probiotic therapy for prevention of G. lamblia infections and may help explain some of the variability of outcomes seen in G. lamblia infections in humans.  (+info)

Antibiosis is a biological interaction between two or more organisms that is detrimental to at least one of them; it can also be an antagonistic association between an organism and the metabolic substances produced by another. Examples of antibiosis include the relationship between antibiotics and bacteria or animals and disease-causing pathogens. The study of antibiosis and its role in antibiotics has led to the expansion of knowledge in the field of microbiology. Molecular processes such cell wall synthesis and recycling, for example, have become better understood through the study of how antibiotics affect beta-lactam development through the antibiosis relationship and interaction of the particular drugs with the bacteria subjected to the compound. Antibiosis is typically studied in host plant populations and extends to the insects which feed upon them. "Antibiosis resistance affects the biology of the insect so pest abundance and subsequent damage is reduced compared to that which would have ...
In more than 25 yr since the discovery of soybean [Glycine max (L.) Merr.] resistance to defoliating insects, attempts to introgress this trait into elite germplasm have been relatively unsuccessful. Resistance to defoliating insects in soybean is expressed as a combination of antibiosis (toxicity) and antixenosis (nonpreference). Both of these resistance modes are inherited quantitatively in soybean. The objectives of this study were (i) to use restriction fragment length polymorphism (RFLP) maps to identify quantitative trait loci (QTLs) in soybean for antibiosis against corn earworm (CEW) (Helicoverpa zea Boddie), (ii) to determine the relative magnitude, gene action, and genomic locations of these QTLs, and (iii) to compare them to previously detected soybean antixenosis QTLs. Restriction fragment length polymorphism maps were constructed in three soybean F2 populations segregating for antibiosis against CEW: `Cobb × PI171451, Cobb × PI227687, and Cobb × PI229358. Antibiosis was measured ...

Microorganisms to Physicochemical Conditions…?, live in a constantly changing environment and must modify their physiology and morphology to cope with these changes. The main systems for molecular adaptation to modifications of environmental conditions and the behavioral responses of prokaryotes in various habitats, excluding extreme habitats, are discussed. The main regulation systems that are described are transcription, signal transduction, and protein modifications. Three specialized systems are also presented in details: quorum sensing, phase variation, and antibiosis. Quorum sensing allows bacteria to trigger some responses when their density is high enough to permit the function to be successful. Phase variation is an adaptive process by which a bacterial subpopulation undergoes frequent, usually reversible phenotypic changes resulting from genetic or epigenetic alterations, allowing rapid modification of the cells physiology. Antibiosis is the ability to synthesize molecules that will ...

The re-growth phenomenon is of concern because of the potential for additional treatment requirement / higher disposal costs and loss of consumer confidence associated with a compliance failure. It is hypothesised that a competitive exclusion treatment could be the solution wherein the digestate be exposed to a probiotic or defined mixture of micro-organisms, to effectively out compete or eliminate any resident E. coli remaining following treatment. The competitive exclusion principle as a treatment method has already seen application in various industrial sectors, the most well-known being the poultry industry. In experiments it was determined that an ...
This project was developed to identify novel methods for high-throughput culturing and screening of C. elegans to investigate age-related metabolic changes and to survey the proteomic and metabolomic factors associated with age-related changes. To accomplish these goals we developed a novel way to grow C. elegans in liquid culture in 96-well microplates for several weeks without suffering significant fluid loss due to evaporation and without needing to shake or unseal the plates for aeration. We also developed methods for assaying the total volume of live C. elegans in microplate cultures using a fluorescence microplate reader and for performing RNAi experiments with dead instead of live bacteria, which allows for the measurement of nematode metabolic parameters without bacterial interference. Using these methods, along with established methods for the global identification of metabolites and proteins by mass spectroscopy, we observed an integrated pattern of changes that occurred at the molecular

Multidrug-resistant (MDR) Gram-negative bacteria have emerged as a serious threat to human and animal health. Bdellovibrio spp. and Micavibrio spp. are Gram-negative bacteria that prey on other Gram-negative bacteria. In this study, the ability of Bdellovibrio bacteriovorus and Micavibrio aeruginosavorus to prey on MDR Gram-negative clinical strains was examined. Although the potential use of predatory bacteria to attack MDR pathogens has been suggested, the data supporting these claims is lacking. By conducting predation experiments we have established that predatory bacteria have the capacity to attack clinical strains of a variety of ß-lactamase-producing, MDR Gram-negative bacteria. Our observations indicate that predatory bacteria maintained their ability to prey on MDR bacteria regardless of their antimicrobial resistance, hence, might be used as therapeutic agents where other antimicrobial drugs fail.

Lysobacter enzymogenes is a ubiquitous plant-associated and environmentally friendly bacterium emerging as a novel biological control agent of plant disease. This bacterium produces diverse antifungal factors, such as lytic enzymes and a secondary metabolite (heat-stable antifungal factor [HSAF]) having antifungal activity with a novel structure and mode of action. The regulatory mechanisms for biosynthesis of antifungal factors is largely unknown in L. enzymogenes. The solo LuxR proteins have been shown to be widespread, playing important roles in plant-associated bacteria. Here, we cloned and studied a solo LuxR protein, LesR, from L. enzymogenes strain OH11. Overexpression but not deletion of lesR significantly impaired HSAF biosynthesis levels and antimicrobial activities but did not show visible effect on production of major lytic enzymes. Overexpression of lesR also led to remarkably accelerated cell aggregation and induced production of a melanin-like pigment in L. enzymogenes; these two
Mycoparasitism is considered a major contributor to fungus-fungus antagonism. The necrotrophs, primarily Trichoderma species, have a wider host range and less-specific mode of action, and perhaps for this reason more field and greenhouse trials have made use of these. Trichoderma species are focused in this chapter, because they have been the focus of the most work at the molecular and cellular levels. The interaction of Trichoderma with soilborne pathogenic fungi is an excellent example of necrotrophic mycoparasitism. Drastic reduction of intracellular cyclic AMP (cAMP) by knockout of adenylate cyclase leads to slow growth and loss of mycoparasitism in T. virens. In T. atroviride, mutants in the ortholog of the same mitogen-activated protein kinase (MAPK) gene, tmk1, showed increased coiling but reduced mycoparasitism in confrontation assays. A potentiation in the gene expression enables Trichoderma-treated plants to be more resistant to subsequent pathogen infection. Chytrids parasitizing vesicular
This study aimed to select an isolate of Lactobacillus spp. from the leaves of Pandanus amaryllifolius with the potential for biofilm development to inhibit various types of food-borne spoilage and pathogenic bacteria. The applicability and usefulness of the newly isolated strain, denoted as Lb. plantarum PA21, were extended via its capacity to express heterologous protein. The imaged biofilms and cell count results showed differences during the biofilm maturation periods. The ability of bacteria to adhere to the abiotic surface in plastic microtiter plates was measured using a conventional biofilm assay. The method offers some advantages compared to the study of biofilm formation in flow cells, which is an alternative widely used method. Watnick and Kotler [29] showed that the microtiter plate assay can be utilized to distinguish true biofilm formation similar to the biofilm grown in flow cells. This method appeared attractive for obtaining quantitative results based on CFU and optical ...

Damping-off is caused by fungus and it usually occurs in small patches at various places in the seedbeds or field. The disease spots often increase from day to day until the seedlings harden. Seedlings are extremely susceptible for about two weeks after emergence. As the stem hardens and increases in size, the injury no longer occurs. Some seedlings are not killed at once, but the roots are severely damaged and the stem is girdled at the ground level. Such plants remain stunted and often do not survive transplanting. The injury from damping-off fungi is of two types ...

The unifying goal of our work is to develop new approaches for the prevention of urinary tract infection (UTI) in persons with spinal cord injury (SCI). Most individuals with SCI have neurogenic bladders, and the resulting urinary stasis and bladder catheterization predispose them to recurrent UTI. Currently few, if any, measures are effective at prevention of UTI in persons with neurogenic bladders.. Bacterial interference, or using benign bacteria to prevent infection with virulent pathogens, may offer a solution to the significant problem of recurrent episodes of UTI in persons with SCI. Two trials in persons with SCI of instilling nonpathogenic Escherichia coli (83972) directly into the bladder demonstrated a strong association between colonization with this non-pathogen and decreased frequency of UTI. However, the successful colonization rate of the direct inoculation method was low (51-62%). Since a urinary catheter-associated biofilm, or bacteria plus extracellular matrix, continually ...
Background: Distribution and evolutionary history of resistance genes in environmental actinobacteria provide information on intensity of antibiosis and evolution of specific secondary metabolic pathways at a given site. To this day, actinobacteria producing biologically active compounds were isolated mostly from soil but only a limited range of soil environments were commonly sampled. Consequently, soil remains an unexplored environment in search for novel producers and related evolutionary questions. Results: Ninety actinobacteria strains isolated at contrasting soil sites were characterized phylogenetically by 16S rRNA gene, for presence of erm and ABC transporter resistance genes and antibiotic production. An analogous analysis was performed in silico with 246 and 31 strains from Integrated Microbial Genomes (JGI_IMG) database selected by the presence of ABC transporter genes and erm genes, respectively. In the isolates, distances of erm gene sequences were significantly correlated to ...
We tested chemical and insect feeding-induced insect resistance on soybean plants.The chemical induction effects of jasmonic acid (JA) and salicylic acid (SA) were investigated. We also evaluated the effects of plants stressed with previous insect herbivory. A larval antibiosis screening technique (LAST) and a preference test were performed in petri dishes using Mexican bean beeetles. Epilachna varivestis Mulsant, to monitor the effects of resistance in soybeam. Results from the LAST assessment showed evidence of both chemical and insect feeding induction of resistance. JA applied to the plant resulted in greater insect mortality and less larval damage than did the controls, indicating an increased resistance to herbivorous stress. In contrast, plants treated with SA had slightly less resistance. In the previously insect-damaged study, plants that had portions of lower leaves consumed by the beetle developed a higher level of resistance to subsequent feeding of the upper leaves. Preference ...
The results of this study confirm that systemic administration of L salivarius 118 had an anti-inflammatory effect on colitis in IL-10 KO mice, demonstrating that the oral route is not mandatory for its effect. It is noteworthy that the anti-inflammatory effect was of comparable, but not superior, magnitude to that previously reported by us using the oral route of administration.9 Dosing and frequency of administration were arbitrary, with a compromise between exposure to the microbes while minimising stress to the animals. Whether alternative regimens would have a greater or lesser impact requires study. The results are not specific to this model, nor to intestinal inflammation, because the anti-inflammatory effect was also seen in a murine model of arthritis. This further supports an earlier observation that probiotic effects are not solely local, but may include systemic anti-inflammatory activity.9 The systemic nature of the probiotic activity is reflected in a decrease in proinflammatory ...

Macrophomina phaseolina is one of the major yield limiting factors of melons in tropical and subtropical regions. For eco-friendly and effective management of the disease, 24 gamma induced mutants from Trichoderma harzianum were evaluated against three isolates of the pathogen representing three geographically different regions viz. Khorasan (isolate 1), Garmsar (isolate 2) and Khuzestan (isolate 3). The isolates of Trichoderma (mutants and wild type) were evaluated against the pathogen in dual culture and through production of volatile and non-volatile inhibitors. Maximum growth inhibition was observed in Th1, Th4, Th15, Th9 and Th22 mutants after three days. In greenhouse evaluation against M. phaseolina (isolate 1) among the inoculated treatments minimum plant infection was observed in Th9 treatment (28% disease reduction) as compared to infected control and among the uninoculated treatments Th1and Th9 mutants resulted in maximum growth of roots and shoots of melon plants as compared to uninfected
Antagonistic effect of seven isolates of Bacillus subtilis has been examined in dual culture tests against Rhizopus nigricans, the incitant of papaya (Carica papaya L.) frult-rot. Isolate AF 1 which caused maximum inhibition (9.6 mm) was grown in potato dextrose broth for 96 h and cell-free culture filtrate was used to study the inhibition. The concentrated extract of culture filtrate of the antagonist was diluted to indicate 0-40 per cent in potato dextrose agar and Richards solution. There was 93% inhibition at 40 per cent in both the media. Germinated spores formed clumps in Richards solution at and above 20 per cent concentration of the antagonistic culture filtrate, but failed to produce sporangia. Concentrated extract induced formation of bulbous structures in hyphae. Biological control of papaya fruit-rot was achieved by dipping the fruits in cell suspension of B. subtilis or in the culture filtrate, 24 h before treatment with R. nigricans. ...
INTRODUCTION. Lactobacillus reuteri is an obligatorily heterofermentative lactic acid bacteria, a microaerophilic, and is a common inhabitant of the gastrointestinal tract of humans (28, 36) and animals such as pigs (12, 24, 33), turkeys, chickens, and monkeys (24). L. reuteri also belongs to the predominant microflora of fermented cereal products and meat (14, 15, 25). Some species of L. reuteri produce the enzyme invertase, which is used in converting sugar from sucrose (17, 26). In addition, L. reuteri also produces a large amount of glucan and fructan exopolysaccharides, which are considered prebiotics (22). These prebiotics have been investigated with regards to antitumour activity (52), immunomodulation (55), and cholesterol reduction (50). In recent years, there has been considerable interest in the use of probiotic microorganisms and organic acids as alternatives to antibiotics in feeds to reduce antibiotic residues in the carcass, among other excellent benefits such as diarrhea control ...

Xanthomonas oryzae pv. oryzae (Xoo) is widely prevalent and causes Bacterial Leaf Blight (BLB) in Basmati rice grown in different areas of Pakistan. There is a need to use environmentally safe approaches to overcome the loss of grain yield in rice due to this disease. The present study aimed to develop inocula, based on native antagonistic bacteria for biocontrol of BLB and to increase the yield of Super Basmati rice variety. Out of 512 bacteria isolated from the rice rhizosphere and screened for plant growth promoting determinants, the isolate BRp3 was found to be the best as it solubilized 97 μg/ mL phosphorus, produced 30 μg/mL phytohormone indole acetic acid and 15 mg/ L siderophores in vitro ...
Quorum sensing molecules (QSMs) are involved in the regulation of complicated processes helping bacterial populations respond to changes in their cell-density. Although the QS gene cluster (comQXPA) has been identified in the genome sequence of some bacilli, the QS system B. licheniformis has not been investigated in detail, and its QSM (ComX pheromone) has not been identified. Given the importance of this antagonistic bacterium as an industrial workhorse, this study was aimed to elucidate B. licheniformis NCIMB-8874 QS. The results obtained from bioinformatics studies on the whole genome sequence of this strain confirmed the presence of essential quorum sensing-related genes. Although polymorphism was verified in three proteins of this cluster, ComQ, precursor-ComX and ComP, the transcription factor ComA was confirmed as the most conserved protein. The cell-cell communication of B. licheniformis NCIMB-8874 was investigated through further elucidation of the ComX pheromone as 13-amino acid ...
Biocontrol formulations prepared from plant-growth-promoting bacteria are increasingly applied in sustainable agriculture. Especially inoculants prepared from endospore-forming Bacillus strains have been proven as efficient and environmental-friendly alternative to chemical pesticides due to their long shelf life, which is comparable with that of agrochemicals. However, these formulations of the first generation are sometimes hampered in their action and do not fulfill in each case the expectations of the appliers. In this review we use the well-known plant-associated Bacillus amyloliquefaciens type strain FZB42 as example for the successful application of different techniques offered today by comparative, evolutionary and functional genomics, site-directed mutagenesis and strain construction including marker removal, for paving the way for preparing a novel generation of biocontrol agents.

Fluorescent viability stains to probe the metabolic status of aflatoxigenic fungus in dual culture of Aspergillus flavus and Pichia anomala. Mycopathologia. 171(2):133-138. Interpretive Summary: Both FUN-1 stain and the combinatorial use of DiBAC4(5) with CDFA-AM stain demonstrated that P. anomala not only inactivated the ATP generating system in A. flavus, but also caused damage in hyphal cell walls and decreased membrane potentials. This study demonstrates the great potential for using viability staining in the evaluation of biocontrol yeast. As we learn more about mechanisms utilized by yeasts to control the target fungus, more effective methods for selecting, formulating and applying biocontrol agents will emerge. Several strains of the yeast species, P. anomala, have been demonstrated to control storage mold in small grains to reduce fruit rot in apple (10) as well as to prevent aflatoxin and ochratoxin ...

Public tendency, of late, is to reduce liberal use of harmful synthesized chemicals for promoting plant health. Today, biological control is becoming a commonly cited disease control option. Biological control agents (BCAs) not only control disease , but also promote plant growth. Application of biological control is based largely on knowledge of control mechanisms employed by antagonists, as well as the means of application that will ensure that an antagonistic population is established. Knowing the advantages is not the only factor that should be considered before application commences as, the disadvantages must be clearly outlined and explored further before a constructive decision as on implementation of biological control. A literature review was undertaken to provide the necessary technical information about biological control, its potential uses, methods of application, mechanisms of action employed, advantages and disadvantages associated with biological control application, public ...
McMahons biggest defense for extinction of all carnivores is that it would be good to prevent the vast suffering and countless violent deaths caused by predation. His assumption that the end of all suffering deaths caused by predation is a good thing fails on two accounts. First, he fails to take into account "predation" in the microbial level. Numerous bacteria on Earth that kill other bacteria are vital to all living organisms. Virtually all, living organisms house predatory bacteria that feed on other bacteria in order to multiply. However, these bacteria also decompose harmful pathogens and aid in absorbing nutrients for survival. For example, in Humans, lactic acid bacteria kill pathogens in the stomach that cause diarrhea. In fact, the elimination of all predating microbes would wipe out all living creatures on earth due to diseases. Although according to McMahon, these causes "animal suffering", most people would not desire the elimination of all predating bacteria. Suppose McMahon ...

  The present study evaluated the resistance of 7 varieties of the broad bean Vicia faba L. to cowpea aphid, Aphis craccivora Koch, 1854. These landraces from the region of Biskra (in the south of Algeria) were selected in an initial field trial and subjected to further testing in the greenhouse. Landrace V51 proved to be the most interesting, in that it resisted aphid attack by mechanisms involving tolerance and antibiosis. Aphid infestation of this landrace resulted in a dry weight loss of only 3.09% (comparison with uninfested plants). The antibiotic resistance of this landrace also significantly decreased the biological potential of the cowpea aphid. In addition to the agronomic and heritage value, some of the landraces of the Biskra region displayed tolerance and antibiosis characteristics suggesting that they might serve as an important genetic resource in future bean selection programs. All tested landraces are attractive to A. craccivora but only this
Sampling. Day-degree models using a developmental threshold of 4°C can be used to predict various phenological events such as egg hatch and immigration of alate aphids. Yellow traps, particularly water pan traps, are commonly used for population monitoring. Sequential sampling plans for green peach aphid on potato were developed by Hollingsworth and Gatsonis (1990). Sampling of aphid natural enemies in this crop was studied by Mack and Smilowitz (1980). Insecticides. Despite the numerous options potentially available, many producers are dependent on insecticides for suppression of green peach aphid abundance. Systemic insecticide applications are especially popular at planting time, most of which provide long-lasting protection against aphid population buildup during the critical and susceptible early stages of plant growth (Powell 1980) and some of which provide protection for 3 months (Palumbo and Kerns 1994). Green peach aphid is often a pest of cold-weather crops such as spinach. Aphids are ...
Various Trichoderma and Bacillus spp. have been documented as being antagonistic to a wide range of soilborne plant pathogens, as well as being plant growth stimulants. Successes in biological control and plant growth promotion research has led to the development of various Trichoderma and Bacillus products, which are available commercially. This study was conducted to evaluate the effect of six Trichoderma spp. and three Bacillus spp. and their respective combinations, for the biological control of Rhizoctonia solani damping-off of cucumber and plant growth promotion of dry bean (Phaseolus vulgaris L.). In vivo biological control and growth promotion studies were carried out under greenhouse and shadehouse conditions with the use of seed treatment as the method of application. In vitro and in vivo screening was undertaken to select the best Trichoderma isolates from 20 Trichoderma isolated from composted soil. For in vitro screening, dual culture bioassays were undertaken and assessed for ...
Disease development. Pre-emergence damping-off is a fungal decay of seeds and young germinants and several different fungi can be involved. Traditionally, Rhizoctonia has been considered to be the major cause of damping-off in ornamental container nurseries (Baker 1957); Peterson (1974) states that four fungal genera (Pythium, Fusarium, Phytophthora, and Rhizoctonia) "are being encountered" in container tree nurseries. A search of the literature, however, reveals that only Fusarium spp. have actually been implicated as a cause of damping-off of conifer seedlings in containers: Fusarium oxysporum (Schlect.) for Douglas-fir (Graham and Linderman 1983); Douglas-fir, western larch, grand fir, subalpine fir, and ponderosa pine (James 1985a); and Douglas-fir and pinyon container seedlings (Landis 1976). Although F. oxysporum is most commonly mentioned, other members of the genus may also cause damping-off disease of container seedlings. James (1985a) recovered F. avenaceum from diseased conifer ...
