Cell-free extracts of Bacillus licheniformis and B. cereus were found to contain high specific activities of nicotinamide adenine dinucleotide phosphate (NADP)-dependent-l-glutamate dehydrogenase [EC 1.4.1.4; l-glutamate: NADP oxidoreductase (deaminating)]. Maximum specific activities were found in extracts of cells during the late exponential phase of growth when ammonium ion served as the sol...

BACKGROUND Biological methods of polycyclic aromatic hydrocarbons (PAH) contamination elimination typically involve the transformation of contaminants to non-toxic materials by microorganisms and plants and appear to be the most effective methods available. METHODS In this study, Bacillus licheniformis and Bacillus mojavensis isolated from oil-contaminated soils were inoculated onto Festuca a...

Nutrient conditions which trigger sporulation also activate expression of the Bacillus licheniformis alpha-amylase gene, amyL. Glucose represses both spore formation and expression of amyL. A fusion was constructed between the B. licheniformis alpha-amylase regulatory and 5' upstream sequences (amyRi) and the Escherichia coli lacZ structural gene to identify sequences involved in mediating temp...

A multi locus sequence analysis (MLSA approach) was studied on the Bacillus genus, or subtilis species complex for specific, including 08 strains from four (B. subtilis, B. pumilus, licheniformis and amyloliquefaciens) were provided by Biotechnology Center of Ho Chi Minh City. The research based sequences 16S rRNA genes, concatenation five protein-coding housekeeping genes: glpF, pta, purH, pyc...

The use of antibiotics in the treatment livestock has increased productivity meat and dairy industry. flip side effectiveness drugs this group is presence effects, which have caused concern about widespread cause need to control residual content antibacterial agents products. From soil samples collected 7 regions Kazakhstan, 14 microbial isolates were isolated identified as B. licheniformis, so...

The development of organic livestock farming, in particular poultry which Ukraine is targeting, requires a radical change approaches to the prevention and treatment infectious diseases. macroorganism microbiota gastrointestinal tract constitute single ecological system with homeostatic balance. However, its violation creates threat an imbalance intestinal normal flora diseases bacterial etiolog...

Three Bacillus species (B. subtilis LFB-FIOCRUZ 1270, B. subtilis LFB-FIOCRUZ 1273, and B. licheniformis LFB-FIOCRUZ 1274), isolated from the poultry industry, were evaluated for keratinase production using feathers or feather meal as the sole carbon and nitrogen sources in a submerged fermentation. The three Bacillus spp. produced extracellular keratinases and peptidases after 7 days. Feather ...

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...
