Antimicrobial activity of methanolic, chloroform, hexane and aqueous stem extracts of Erythrina variegata L. were analyzed against nine bacterial pathogens such as Salmonella typhi, Pseudomonas putida, Pseudomonas aeruginosa, Escherichia coli, Klebsiella sp., Proteus sp., Serratia marcescens, Bacillus circulans, Staphyloccus aureus and five fungal pathogens viz. Aspergillus niger, Aspergillus f...

The alkaliphilic hemicellulolytic bacterium Bacillus sp. N16-5 has a broad substrate spectrum and exhibits the capacity to utilize complex carbohydrates such as galactomannan, xylan, and pectin. In the monosaccharide mixture, sequential utilization by Bacillus sp. N16-5 was observed. Glucose appeared to be its preferential monosaccharide, followed by fructose, mannose, arabinose, xylose, and ga...

Purpose: Robust pharmaceutical and industrial enzymes from extremophile microorganisms are main source of enzymes with tremendous stability under harsh conditions which make them potential tools for commercial and biotechnological applications. Methods: The genome of a Gram-positive halo-thermotolerant Bacillus sp. SL1, new isolate from Saline Lake, was investigated for the presence of genes co...

Harmful algal blooms caused by Phaeocystis globosa have resulted in staggering losses to coastal countries because of their world-wide distribution. Bacteria have been studied for years to control the blooms of harmful alga, however, the action mechanism of them against harmful algal cells is still not well defined. Here, a previously isolated algicidal bacterium Bacillus sp. LP-10 was used to ...

Xanthan gum is a biopolymer produced by Xanthomonas sp. XC6. In this study, xanthan gum is produced from potato starch using a stepwise bioprocess design. Potato starch is hydrolyzed using Bacillus sp. having amylase activity and 30.2 g/L reducing sugar was released, while Xanthomonas sp. XC6 can release only 14.5 g/L. Bacillus sp. hydrolyzed potato starch extract was further used as a carbon s...

The number and types of microorganisms in the gut of Culex quinquefasciatus larvae varied considerably from one site of collection to another. Larval gut, in general, contained enormous number of bacteria, a few fungi and negligible number of actinomycetes which belonged to 15 bacterial, 6 fungal and 4 actinomycete genera, respectively. Bacillus sp., Staphylococcus sp. and Pseudomonas sp. among...
