Efficacy and safety profile of a subtilisin protease produced by fermentation in Bacillus licheniformis to be used as a feed additive

The efficacy and safety of a novel Subtilisin protease from a Bacillus sp.produced in Bacillus licheniformis was investigated in broiler chickens, and a range of toxicological tests, respectively.The B.licheniformis production strain culture supernatant was not found cytotoxic in a Vero cell assay.Subtilisin was non-mutagenic Gooseneck Pot and non-

Phenotypic and Genomic Comparison of the Two Most Common ExoU-Positive Pseudomonas aeruginosa Clones, PA14 and ST235

ABSTRACT Genotyping of 2,882 Pseudomonas aeruginosa isolates that had been collected during the last 40 years identified the ExoU-positive lineages PA14 (ST253) and ST235 as the second and third most frequent clones in the P.aeruginosa population.Both clones were approximately 2-fold more frequently detected in animate habitats than in soil or aqua

Salinity Acclimation Strategies in Nitrifying Bioreactors

Several industries, including aquaculture, produce effluents with high or varying salt concentrations.The treatment of such effluents by the biological nitrification process can be challenging, as the microbes performing this process are sensitive to salinity.In certain cases, such as in recirculating aquaculture systems (RAS), it is essential to m
