TL;DR: Elicitation of induced systemic resistance (ISR) by plant-associated bacteria was initially demonstrated using Pseudomonas spp.

TL;DR: It is indicated that there is a high level of resistance to widely used agents in causative methicillin-resistant CoNS strains, however fusidic acid has the smallest resistance ratio, with the exception of glycopeptides.

TL;DR: Dual culture studies revealed that C. globosum, P. chrysogenum and Streptomyces sp.

TL;DR: Cicerfuran was the only 2-arylbenzofuran that showed antimicrobial activity with MICs as low as 25microg/ml, and stilbenes with a free hydroxyl group were active against both bacteria and fungi withMICs in the range 25-100microG/ml.

TL;DR: One hundred and twenty (120) strains of lactic acid bacteria were enumerated and isolated from raw dromedary milk in Morocco using various cultured media and showed that high counts of LAB were found.

TL;DR: The results indicate that the rhamnolipid-biosurfactant from Pseudomonas sp.

TL;DR: Rhizosphere soil samples were taken from an assay with different crop rotations and tillage systems, and populations of Trichoderma spp.

TL;DR: Cd and Hg emerged as the highly resistant heavy metal pollutants in the Gulf of Mannar biosphere reserve, with a new insight into the development of indicator models.

TL;DR: Bacillus subtilis strains isolated from cowdung had several beneficial attributes, which included biocontrol, plant growth promotion, sulphur (S) oxidation, phosphorus (P) solubilization and production of industrially important enzymes (amylase and cellulase).

TL;DR: Large-scale phylogenetic analysis of sponge-derived fungi may provide critical information to distinguish between 'resident fungi' and 'transient fungi' in sponges as it has been done in other marine microbial groups.

TL;DR: B. megaterium F7-1 presented high keratinolytic activity and was very effective in feather degradation, providing potential use for biotechnological processes of keratin hydrolysis.

TL;DR: Knowing the influence of plant growth stages on the population size and community structure of culturable bacteria and fungi associated with rhizoplane and endo-rhizosphere of maize grown in field is relevant for exploring endophytic rhizobacteria potential in the promotion of plant-growth, protection against pathogens and to detect perturbations in natural agro ecosystems.

TL;DR: It is demonstrated that amoebae like A. castellanii can play a crucial role in the increase and spread of L. pneumophila in anthropogenic aquatic systems and thus in the occurrence of Legionnaires' disease.

TL;DR: The statistical optimization by response surface methodology resulted in a three-fold increase in the production of laccase by S. psammoticus MTCC 7334 in submerged fermentation.

TL;DR: A 16S-DGGE approach was used to estimate bacterial diversity and to monitor community changes in two aerated lagoons from a wastewater treatment plant receiving urban and industrial effluents.

TL;DR: The present study indicates that S. fusiformis is very effective in removal of chromium (93-99%) besides removing other toxicants from retan chrome liquor and can be applied for detoxification of tannery effluents.

TL;DR: 13-Acetyl solstitialin A displayed remarkable antibacterial activity against isolated strains of E. faecalis at 1 microg/ml concentration, which was close to the effective concentrations of ampicillin, and showed significant activity against the DNA virus.

TL;DR: In this paper, a phylogenetic analysis of the retrieved genes revealed that the encoded products of these cellulase genes shared less than 50% identities and 70% similarities to cellulases in the databases.

TL;DR: A protein linkage map is summarized that is consistent with the model for the secretion apparatus and can be used as a basis to identify inhibitors of specific interactions in Saccharomyces cerevisiae.

TL;DR: The effect of 2,4-dichlorophenoxy acetic acid treatment for rice seedlings grown under gnotobiotic conditions is to create a niche in which these bacteria can grow.

TL;DR: A protease-producing bacterium isolated from slaughterhouse waste samples, Hyderabad, India, was related to Bacillus cereus on the basis of 16S rRNA gene sequencing and biochemical properties and showed extreme stability and activity even in the presence of detergents and anionic surfactants.

TL;DR: Rarefaction curves indicate that the species richness of cerrado sensu stricto is greater than that of c Kerrado converted to pasture and lineage-through-time plots show that the expected richness of species present in cerrados sensi stricto soil is approximately 10 times greater than the expected wealth of species in the converted area.

TL;DR: Hirsutella rhossiliensis OWVT-1 has substantial potential as a biocontrol agent against plant-parasitic nematodes and of entomopathogenic fungi and clustered with the serine proteases of parasites of nematode eggs rather than with those of the trapping fungi.

TL;DR: The developed multiplex RT-PCR assay is a rapid, sensitive and specific assay for detecting of AIV subtypes and as sensitive as the virus isolation method in detecting H9N2 from tracheal samples collected at day 3 and 5 post inoculation.

TL;DR: Amplified fragment length polymorphism (AFLP) using 14 primer combinations and internal transcribed spacer (ITS) PCR-RFLP were used in a comparative study which indicated that the genotype study at molecular level is a useful complement method to the current classification system of Ganoderma strains based on morphological traits.

TL;DR: Attempts were made for hyper production of tylosin by a strain of Streptomyces fradiae NRRL-2702 through irradiation mutagenesis throughUltraviolet (UV) irradiation of wild-type strain caused development of six morphologically altered colony types on agar plates, and mutant gamma-1 displayed high stability on subsequent culturing.

TL;DR: A new hypocrellin A-producing strain, Shiraia sp.

TL;DR: This work investigated and compared the influence of iron(III) concentration on the growth of and siderophore production by two heterotrophic bacteria--Micrococcus luteus and Bacillus silvestris and showed that the iron concentration strongly influences thegrowth of both species.

TL;DR: The pathogenicity of a new China variety of Metarhizium anisopliae against the subterranean termite Odontotermes formosanus and the effect of the fungal fermented solution on hemolymph intracellular calcium were studied in laboratory.

TL;DR: The results suggest that in strain 2P24, RpoS could only play its negative regulatory role on the pcoI gene under a functional GacS/GacA system background.
