Factors affecting transformation of Bacillus licheniformis.
Thorne, Curtis B. (Fort Detrick, Frederick, Md.), and Harold B. Stull. Factors affecting transformation of Bacillus licheniformis. J. Bacteriol. 91:1012-1020. 1966.-Transformation systems involving two types of transformable mutants of Bacillus licheniformis 9945A were compared. Each system required its specific growth medium, but a single transformation medium could be used for both. Cells fro...
متن کاملTransformation to Prototrophy and Polyglutamic Acid Synthesis in Bacillus Licheniformis.
Leonard, C. Gomez (U.S. Army Biological Laboratories, Fort Detrick, Frederick, Md.), D. K. Mattheis, M. J. Mattheis, and R. D. Housewright. Transformation to prototrophy and polyglutamic acid synthesis in Bacillus licheniformis. J. Bacteriol. 88:220-225. 1964.-Growth conditions necessary for transformation to prototrophy of 14 auxotrophs of Bacillus licheniformis were studied. The unexpected fi...
متن کاملConditions for competence in the Bacillus licheniformis transformation system.
Some variables in the Bacillus licheniformis transformation system, such as inoculum size, initial cell density in transformation medium, and time of optimal competence, have been explored, and a methodology has been developed to obtain greater reproducibility and maximal competence for transformation. The transformation system in B. licheniformis has been shown to be similar to that of B. subt...
متن کاملRegulation of alanine dehydrogenase in Bacillus (licheniformis).
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...
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...
