Formation of Bacitracin by Washed Cell Suspensions of Bacillus Licheniformis.
Although the microbial formation of a variety of polypeptides possessing antibiotic activities has been known for some time, the biosynthesis of these compounds has as yet received little attention. Not only is the mechatnism of formation of these biologically active compounds of interest in itself, but the biosyntheses of these polypeptides are potential systems for investigating the general p...
متن کاملCharacteristics of penicillinase release by washed cells of Bacillus licheniformis.
Saline-washed cells of Bacillus licheniformis strain 749/C (constitutive for penicillinase) were able to release exopenicillinase in the presence of concentrations of chloramphenicol that prevented protein synthesis completely. The release reaction was strongly pH-dependent, occurring at a faster rate at alkaline pH in anionic or cationic buffers than at neutral pH. A strongly pH-dependent rele...
متن کاملThe 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 ...

15 صفحه اولEnhanced Production of Bacitracin by a Mutant Strain Bacillus Licheniformis Uv-mn-hn-8 (enhanced Bacitracin Production by Mutagenesis)
The present study is focused on the improvement of Bacillus licheniformis through random mutagenesis to obtain mutant having enhanced production of bacitracin. Many isolates of Bacillus licheniformis were isolated and the isolate GP-40 produced maximum bacitracin production (16±0.72 IU/mL). Treatment of Bacillus licheniformis GP-40 with ultraviolet (UV) radiations increased bacitracin productio...
