TL;DR: On the basis of multiple plant growth promoting activities, eleven bacterial isolates were evaluated for their quantitative IAA production, and broad-spectrum antifungal activity on Muller-Hinton medium against Aspergillus, one or more species of Fusarium and Rhizoctonia bataticola.

TL;DR: The present paper reviews the studies published to date on antifungal applications of PACT and aims to raise awareness of this area of research, which has the potential to make a significant impact in future treatment of fungal infections.

TL;DR: Five bacterial strains with phosphate-solubilizing ability and other plant growth promoting traits increased the plant biomass by paper towel method by boosting the grain yield of field-grown maize by 85% and 64% compared to the uninoculated control.

TL;DR: The main changes observed under light and scanning electron microscopy after oil treatment were loss of cytoplasm in fungal hyphae, and budding of hyphal tip, and the hyphal wall and its diameter became markedly thinner, distorted and resulted in cell wall disruption.

TL;DR: It is concluded that real-time PCR is a very sensitive and precise technique for extensive quantitative evaluation of gut Bifidobacterium spp.

TL;DR: The stability of crude extracellular protease produced by Bacillus licheniformis RP1, isolated from polluted water, in various solid laundry detergents was investigated and showed excellent stability and compatibility with a wide range of commercial solid detergENTS at temperatures from 40 to 50 degrees C, suggesting its further application in detergent industry.

TL;DR: Pseudomonas corrugata, a soil bacterium originally isolated from a temperate site of Indian Himalayan Region (IHR) is examined for its antagonistic activities against two phytopathogenic fungi, Alternaria alternata and Fusarium oxysporum.

TL;DR: The T. boveana volatile oils exhibited an interesting antibacterial activity against all strains tested except Pseudomonas aeruginosa but no antifungal activity was detected.

TL;DR: The recovery of strains producing antimicrobial and surface-active substances suggests that microorganisms associated with the marine bivalve are potential source of bioactive metabolites.

TL;DR: It was found that oils from both parts of R. acaule, and especially that of C, exhibited interesting antibacterial activity, but no antifungal activity was observed.

TL;DR: It seems to indicate that in this soil ecosystem, copper influenced the culturable bacterial communities, affecting the structural diversity and altering some of the metal resistance of the microorganisms.

TL;DR: Genotypic variations of S. aureus strains isolated from different origins in Argentina are described to provide a valuable insight into molecular specificities of this important pathogen.

TL;DR: Cross inhibition tests with bacteriocin producer strains and plasmid profiles indicated that entomocin 110 is a new bacteriOCin, which genetic determinants are probably harbored by the chromosome.

TL;DR: Initial pH value and lactate (electron donor) concentration were found to influence the reduction rate of Cr(VI), and the optimal conditions were at pH 9.0 and supplemented with 40 mM of lactate.

TL;DR: The compounds tested showed excellent in vitro antibacterial activity against Staphylococcus aureus and had variable activity against E. coli, although these compounds are less active against P. aeruginosa.

TL;DR: The composition of volatile organic compounds released by the entomopathogenic fungus Beauveria bassiana utilizing two different carbon sources was investigated and found diisopropyl naphthalenes, ethanol, and sesquiterpenes.

TL;DR: Among the 49 strains of moderately halophilic bacteria isolated from the salty environments of Iran, a Gram-positive coccus designated as strain QW6 showed high capacity in the removal of toxic oxyanions of tellurium in a wide range of culture medium factors.

TL;DR: It was shown that chlorate sensitivity in Macrophomina had some relations with charcoal rot severity in sorghum, and chlorate-sensitive isolates were found to be genetically closer than the resistant ones.

TL;DR: A newly isolated thermophilic strain producing thermostable lipase was identified based on 16S rRNA sequencing, where phylogenetic analysis revealed its closeness to Geobacillus thermoleovorans.

TL;DR: The viability of Vibrio fluvialis in seawater microcosms, with and without sediment was investigated and the strain survived as culturable bacteria for at least 1 year and the expression of its virulence factors was maintained.

TL;DR: In this study, an aiiA gene was cloned from Bacillus subtilis BS-1 by PCR with a pair of degenerate primers and the deduced 250 amino acid sequence contained two small conserved regions, 103SHLHFDH109 and 166TPGHTPGH173, which are characteristic of the metallo-beta-lactamase family.

TL;DR: Growth, N, P, chlorophyll and phenol content and yield of cowpea were highest in plants treated with G. mosseae+R.

TL;DR: This study investigates if electrochemical disinfection is able to eliminate contamination of tap water systems contaminated with bacterium Legionella pneumophila by means of electrolysis cell or bacteria added to tap water after passage through such disinfection unit.

TL;DR: The actinomycete strain of Streptomyces lydicus was found to be a potent producer of polygalacturonase and the best medium was selected for further studies.

TL;DR: It is concluded that PCR and subsequent DGGE are useful to monitor community shifts in anaerobic fermenter sludge, however, as these changes are not readily detectable via DGGE-pattern analysis, alternative factors influencing the fermenter functioning should be found and investigated.

TL;DR: Specific enzymatic assays demonstrate that keratinase can act on a large variety of soluble and insoluble protein substrates.

TL;DR: An antifungal substance produced by Paenibacillus brasilensis strain Sa3 was preliminary characterized and showed to be stable after treatment with different enzymes and organic solvents and at a wide range of pH, and presented a molecular weight between 3 and 10 kDa.

TL;DR: Cuttlefish powder (CFP) from Sepia officinalis by-products was prepared and tested as a fermentation substrate for microbial growth and protease production by several species of bacteria indicating that the strains can obtain their carbon and nitrogen source requirements directly from whole by-product proteins.

TL;DR: The in vivo tests in mice indicate that WIPS1 and WEPS1 had significant antitumor and antioxidative activities to some extent.

TL;DR: Twenty-nine rhizobial isolates from root nodules of the wild Legumes Astragalus, Lespedeza and Hedysarum growing in the northwestern region of China, were characterized by numerical taxonomy, RFLP and sequencing of PCR-amplified 16S rDNA genes, and cross-nodulation with selected Legume species.
