Evaluation of Cholesterol Reduction in Probiotic Strain Lactobacillus brevis isolated from Human Fecal Sample by Using Surface Response Methodology
Abstract: Lactobacillus brevis, isolated from human feces was assessed for its in vitro cholesterol reduction ability. The effects of bile salts, inoculum size and contact time in simulated intestinal juice were studied. Central composite design model was utilised to determine the effects of interactions of significant variables on cholesterol reduction. By developing a linear regression model, as a function of growth associated variables in vitro cholesterol reduction was assessed. The results …

All Climates Carboxymethyl Cellulase from Psychrophilic Fungus Truncatella angustata
Abstract: The aim of this research was to screen the activity of carboxymethyl cellulase (CMCase) in laboratory stocks of psychrotrophic fungi (Penicillium canescens BPF4, Truncatella angustata BPF5 and Pseudogymnoascus roseus BPF6). Of the three fungal species, the psychrotrophic fungus T. angustata showed maximum CMCase activity under cold temperatures. The maximum CMCase activity from T. angustata was found at 40°C, a residual activity of 60 % at 4°C, 90% at 10°C, 75% …

Characterization of Laccase Enzyme from Dye Degrading Bacterial Strains Isolated from Natural Sources
Abstract: The continuous growth in globalization and industrialization has increased the environmental pollution and one such major contaminant is various types of synthetic dyes. Microbial decolorization and degradation of these dyes through secretion of various extracellular enzymes is gaining importance owing to their eco-friendly nature. One such enzyme is laccase, a multicopper oxidase enzyme which has the ability to oxidize both phenolic and non-phenolic compounds through reduction of molecular oxygen to …

Screening and Characterisation of Antibacterial Actinomycetes Isolated From Earthworm
Abstract: The actinomycetes are considered to be the most potent source for the production of secondary metabolites, antibiotics and other bioactive compounds. The present study dealt with the isolation of the actinomycetes from the earthworm, Eisenia fetida. The actinomycetes were identified using slide culture technique and various biochemical tests. The isolates (S1 and S2) showed activity against Gram positive and Gram negative bacteria in primary screening by perpendicular streak method. In …
