The colonization and survival of Bacillus species, members of the cutaneous microbial community of humans, were investigated by applying spores of Bacillus licheniformis to the forearms of volunteers. Four strains were tested, including the bacitracin producer ATCC 10716 and its bacitracin-negative mutant. Germination occurred within 24 h. Significant differences in survival population and dura...

Advancement in green chemistry has increased the use of microbial hydrolyases various industries and chemical processes because high catalytic efficiency, specificity, cost-effectiveness eco-friendly nature. Bioconversion tannins such as tannic acid is achieved by tannin acyl hydrolase, also known tannase. It converts into glucose gallic catalyzing hydrolysis ester depside linkages acid. Tyrosi...

Cell extracts of Bacillus licheniformis were found to contain nicotinamide adenine dinucleotide (NAD)-dependent l-alanine dehydrogenase (ADH) (l-alanine: NAD oxidoreductase, EC 1.4.1.1). High specific activities (3.5 to 6.0 IU/mg of protein) were found in extracts of cells throughout growth cycles only when l-alanine served as the primary source of carbon or carbon and nitrogen. Specific activi...

The relative isolation and unique physical properties of the Savusavu Hot Springs in Fiji may yield unique thermophiles. This study was conducted to determine the presence of aerobic thermophilic bacteria in these hot springs. A total of 104 thermophilic bacterial isolates were characterized and using Thermus and Bacillus strains as controls, 58% of the isolates were identified as Anoxybacillus...

This study presents effects of some nutritional and environmental factors on cellulases production by isolates, Bacillus licheniformis WBS1 and Bacillus sp. WBS3, which have been isolated from an Indian hot spring. Activity of both CMCase and FPase were higher in case of wheat straw. Maximum enzymatic activity was found at following optimum parameters: pH (8.0 when grown on rice, 9.0 when grown...

This study was conducted to investigate the effect of feed types on Ochratoxin A (OTA) degradation by Korean native goats. Rumen fluid from canulated goats fed whole roughage or 50% roughage served as a source of micro-organisms. Experiments were undertaken i) to investigate OTA degradation ability in a 2×4 factorial arrangement with different feed types (100% roughage vs. 50% roughage) and rum...

Bacitracin is a widely used metallopeptide antibiotic produced by Bacillus subtilis and Bacillus licheniformis with a potent bactericidal activity directed primarily against Gram-positive organisms. This antibiotic requires a divalent metal ion such as Zn(2+) for its biological activity, and has been reported to bind several other transition metal ions, including Mn(2+), Co(2+), Ni(2+), and Cu(...

Quantitative mass conversion of intact bacterial cells of Bacillus subtilis and B. licheniformis to L-phase variants has been effected after lysozyme treatment. After subculture of the unstable L-phase variants for several months in the presence of methicillin, stable L-phase variants were obtained which grew in the absence of the antibiotic and were then unable to revert to the classical bacte...

The Gram-positive endospore-forming bacterium Bacillus licheniformis can be found widely in nature and it is exploited in industrial processes for the manufacturing of antibiotics, specialty chemicals, and enzymes. Both in its varied natural habitats and in industrial settings, B. licheniformis cells will be exposed to increases in the external osmolarity, conditions that trigger water efflux, ...
