cold active hydrolytic enzymes production by psychrotrophic bacilli isolated from three sub-glacial lakes of nw indian himalayas.the diversity of culturable, cold-active enzymes producing bacilli was investigated from three sub-glacial lakes of north western indian himalayas. amplified ribosomal dna restriction analysis (ardra) using three restriction enzymes alu i, msp i, and hae iii led to the clustering of 136 bacilli into 26, 23, and 22 clusters at 75% similarity index from chandratal lake, dashair lake, and pangong lake, respectively. phylogenetic analysis based on 16s rrna gene sequencing led to the identification o ...201626933936
antagonistic interactions between heterotrophic bacteria as a potential regulator of community structure of hypersaline microbial mats.microbial mats are laminae of self-sustaining microbial communities with a high level of competition for resources. we tested the hypothesis that chemically mediated antagonism is a potential mechanism for structuring the bacterial community. in the co-culturing assay, 57% of the isolates expressed antagonistic behavior toward one or more isolates and 5% of the isolates inhibited more than 80% of the isolates. we observed greater levels of antagonism between isolates from adjacent laminae than w ...201322809069
green synthesis of graphene and its cytotoxic effects in human breast cancer cells.this paper describes an environmentally friendly ("green") approach for the synthesis of soluble graphene using bacillus marisflavi biomass as a reducing and stabilizing agent under mild conditions in aqueous solution. in addition, the study reported here investigated the cytotoxicity effects of graphene oxide (go) and bacterially reduced graphene oxide (b-rgo) on the inhibition of cell viability, reactive oxygen species (ros) generation, and membrane integrity in human breast cancer cells.201323687445
