Biotransformation of podophyllotoxin (PT) by several microbial species has been investigated. Among the fungi tested, it was found that Penicillium strains can isomerize PT to picropodophyllin (PPT) in 8% yield and other strains also transform the substrate into the same product but with lower yield.

The concerted activity of intestinal microbes is crucial to the health and development of their host organisms. Investigation of microbial interactions in the gut should deepen our understanding of how these micro-ecosystems function. Due to advances in Next Generation Sequencing (NGS) technologies, various bioinformatic strategies have been proposed to investigate these microbial interactions....

Vancomycin in combination with ciprofloxacin exhibited synergy against 7 of 10 strains of Pseudomonas aeruginosa. MICs for the microbial strains used in this study ranged from 0.0325 to 3.0 micrograms/ml for ciprofloxacin and from 23.5 to > 188 micrograms/ml for vancomycin. Combinations of these antibiotics, tested in a checkerboard pattern, gave fractional inhibitory concentrations of 0.5 or l...

Closely related strains of thermophilic Synechococcus were cultivated from the microbial mats found in the effluent channels of Mushroom Spring, Yellowstone National Park (YNP). These strains have identical or nearly identical 16S rRNA sequences but are representative of separate, predicted putative ecotype (PE) populations, which were identified by using the more highly resolving psaA locus and ...

This paper focuses on the comparison of microbial biomass increase (cell culture growth) using field-relevant testing methods and moving away from colony counts. Challenges exist in exploring antimicrobial growth fastidious strains, poorly culturable bacteria bacterial communities environmental interest. Thus, various approaches have been explored to follow that can be efficient surrogates for ...

This research focused on the isolation and characterization of new strains which can be used as microbial resources for auxin production in agriculture industry. For microorganism gut Larimichthys polyactis, a marine agar medium was 3 colonies were isolated. Through 16S-based ID service, isolated identified 1 strain Niallia circulans Proteus mirabilis. Verifying industrial values these strains,...
