UV Induced Increase in Activity of Subtilisin from Bacillus subtilis MTCC441
Abstract: Microorganisms are constantly exposed to varying physical, chemical and biological conditions which induce morphological, biochemical and genetic changes in them. These changes may be deleterious to some organisms whereas others develop mechanisms to overcome such stresses. This study was conducted to understand the microbiological and biochemical changes in bacteria under conditions of UV stress. Bacillus subtilis MTCC441, a ubiquitous, spore forming bacterium was chosen as the model organism for this …

Anthrax Toxin Time-Resolved Absorption and Resonance FT-IR and Raman Biospectroscopy and Density Functional Theory (DFT) Investigation of Vibronic-Mode Coupling Structure in Vibrational Spectra Analysis
Abstract: Anthrax toxin is a three-protein exotoxin that is secreted by the bacterium's virulent strains, the anthrax causative agent Bacillus anthracis. Harry Smith first found the toxin in 1954. Anthrax toxin consists of a protein called a protective antigen (PA) binding cell protein and two enzyme parts called an edema factor (EF) and a deadly factor (LF). These three protein components act together to impart their physiological effects. Assembled complexes containing …
