The production of bacitracin synthetase by Bacillus licheniformis ATCC 10716.
Bacitracin synthetase is an enzyme complex [ 1,2] composed of three complementary fractions called A, B and C [3] (see fig.1). F’hosphopantetheine which is covalently bound to the fractions [2,3,.5] is probably involved in the biosynthesis of bacitracin. Similar to gramicidin S and tyrocidine [6] its mechanism of synthesis has been described as a thiotemplate mechanism [7]. In the present work ...
متن کاملSurvival of bacillus licheniformis on human skin.
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...
متن کاملEffects of glucose and glycerol on gamma-poly(glutamic acid) formation by Bacillus licheniformis ATCC 9945a.
Bacillus licheniformis ATCC 9945a is one of the bacterial strains that produce gamma-poly(glutamic acid) (gamma-PGA). The use of carbohydrate medium components for gamma-PGA production was explored. Cells were grown in shake flasks or in controlled pH fermentors using medium formulations that contain different carbon sources. During the cultivations, aliquots were removed to monitor cell growth...
متن کاملEfficient simultaneous saccharification and fermentation of inulin to 2,3-butanediol by thermophilic Bacillus licheniformis ATCC 14580.
2,3-Butanediol (2,3-BD) is an important starting material for the manufacture of bulk chemicals. For efficient and large-scale production of 2,3-BD through fermentation, low-cost substrates are required. One such substrate, inulin, is a polydisperse fructan found in a wide variety of plants. In this study, a levanase with high inulinase activity and high pH and temperature stability was identif...
متن کاملStabilization of Bacillus Licheniformis ATCC 21415 Alkaline Protease by Immobilization and Modification
Alkaline protease from Bacillus licheniformis ATCC21415 was partially purified by fractional precipitation at 70% ethanol which showed 6.2-fold purification. Immobilization of the enzyme by physical adsorption on loofa (as a new carrier) had the highest immobilization yield (70.5%).Chemical modification of the enzyme by covalent coupling with sodium -periodate activated amylopectin retained (78...
