This study focuses on the isolation and characterization of a novel strain of siderophore producing bacterium, i.e., Pseudomonas aeruginosa BUP2 (Pa BUP2) from the rumen of Malabari goat, coupled with qualitative and quantitative analyses of the siderophore produced by it. Pa BUP2—a facultative anaerobe was tuned to be an aerobe by repeatedly growing in(More)
This study introduces a novel bacterium-Pseudomonas sp. strain BUP6-isolated from the rumen of the Malabari goat with efficiency for producing lipase. It showed significant production of lipase when grown in a newly designed basal medium, supplemented with vegetable oil. Suitability of five vegetable oils such as groundnut oil, coconut oil, olive oil,(More)
Owing to the production of alpha, beta and gamma amylase subtypes; starch degrading microbes, especially bacteria have an invincible role in the food, fermentation, textile and paper industries. Of them, α-amylases from Bacillus spp. have contributed tremendous advancements in bio-industry, especially in starch, detergent and pharmaceutical arena. Though(More)
This unique study reports a new strain (BPU1) of Candida tropicalis isolated from the rumen of the Malabari goat, showing dual production of biosurfactant and polyhydroxybutyrate. C. tropicalis strain BPU1, a facultative anaerobe, was tuned to become an aerobe in specially designed flask, the Benjamin flask. The puffy circular colonies were smooth,(More)
This study describes the isolation and characterization of a novel fungus, Aspergillus flavus BS1 and its cellulolytic activities with special emphasis on endoglucanase production. Preliminary screening studies showed that A. flavus BS1 was a potent strain for the production of cellulase. To study the cellulolytic activities in detail by submerged(More)
This study describes the characteristics of a biosurfactant produced by Pseudomonas sp. BUP6, a rumen bacterium, and optimization of parameters required for its production. Initial screening of five parameters (pH, temperature, agitation, incubation, and substrate concentration) was carried out employing Plackett-Burman design, which reduced the number of(More)
Employing fluorescent quenching mechanism, type 2 pyoverdine (PVD) purified from Pseudomonas aeruginosa strain BUP2 (new strain isolated from the rumen of Malabari goat) was used as a simple, convenient and inexpensive tool for the rapid detection of Fe and Cu ions in contaminated drinking water samples. The fluorescence emitted at λ460 by PVD (in sterile(More)
