Diversity of Antimicrobial Peptides in Silkworm.

Antimicrobial resistance is a phenomenon that the present-day world is witnessing that poses a serious threat to global health. The decline in the development of novel therapeutics over the last couple of decades has exacerbated the situation further. In this scenario, the pursuit of new alternative therapeutics to commonly used antibiotics has gained predominance amongst researchers across the world.

Phylogenetic diversity of sulfate-reducing bacteria of sediments of Chilika Lake, India, determined through analysis of the dissimilatory sulfite reductase () gene.

In this study, the sulfate-reducing bacteria, (SRB) were identified and reported for the first time through analysis of functional gene , from the DNA of sediment samples collected from 10 sites of the Chilika lake. The finding illustrates Forty six Operational Taxonomic Units (OTUs), identified from the DGGE which were obtained from the 10 sediment samples. Of these, 34 OTUs exhibited around 78-96% sequence similarity and 12 OTUs showed 97 to 100% sequence similarity to the gene of reported type strains of SRB.

Lysinibacillus xyleni sp. nov., isolated from a bottle of xylene.

A Gram-staining-positive, solvent-tolerating (acetophenone, benzene, toluene, xylene and hexane), aerobic, non-motile, terminal endospore-forming, rod-shaped bacterium was isolated from a bottle of xylene. The strain, designated JC22(T), was found to be oxidase and catalase positive. The strain was able to tolerate solvents with different log p values like acetophenone (log P = 1.
