Nitric oxide (NO) produced by bacterial NOS functions as a cytoprotective agent against oxidative stress in Staphylococcus aureus, Bacillus anthracis, and Bacillus subtilis. The screening of several NOS-selective inhibitors uncovered two inhibitors with potential antimicrobial properties. These two compounds impede the growth of B. subtilis under oxidative stress, and crystal structures show th...

The antibacterial activity of Wrightia tinctoria (Roxb.) R. Br. callus extract was studied against selected pathogenic bacterial strains, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis by Agar disc diffusion method. Among the three solvents and water were used , methanol extract of callus showed higher inhibition zone against Pseudomonas aeruginosa (27 mm)...

A partial amino-acid sequence of Bacillus subtilis 168 flagellin is presented. The region of unassigned sequence in this 304-residue polypeptide chain spans residues 158-173. Comparison of the 27-residue aminoterminal CNBr peptide of B. subtilis 168 flagellin with that derived from the flagellin of the serologically unrelated strain of B. subtilis, W23, shows only three conservative substitutio...

This study was carried out to investigate the impacts of bacterial inoculation on texturally different soil samples under greenhouse conditions. Sandy loam (SL), clay (CL), and (C) textured soils were inoculated with Bacillus arenosi K64 (B. arenosi), megaterium M3 megaterium), subtilis OSU 142 subtilis) isolates then incubated at 5 periods [I (20 days), II (40 III (60 IV (80 V (100 days)]. Soi...

A rapid and cost-effective colorimetric sensor has been developed for the detection of bacteria (Bacillus subtilis was selected as an example). The sensor was designed to rely on lysozyme-capped AuNPs with the advantages of effective amplification and high specificity. In the sensing system, lysozyme was able to bind strongly to Bacillus subtilis, which effectively induced a color change of the...

Bacillus thuringiensis produces crystal proteins (Cry) that account for up to 25% of the dry cell weight during the stationary phase. The high-level expression and stationary phase-specific autoinduction of the cry gene led to development of a cry promoter-based Bacillus expression system. Among the various cry promoters, cry3Aa promoter was selected by comparing the lacZ expression levels in B...

Microbial degradation of petroleum hydrocarbons is one of the major practices in natural decontamination process. The present study investigated about the isolation of bacteria from crude oil contaminated site and gravimetric analysis of degradation in which, two bacterial isolates formed maximum clearing zone on mineral salt medium. Among these isolate S2 showed maximum growth (0.85mg/ml) and ...
