Diumycin, janiemycin, nisin, and subtilin inhibited peptidoglycan synthesis catalyzed by particulate enzyme systems from Bacillus stearothermophilus and Escherichia coli. All of these, except for nisin, also induced accumulation of the lipid intermediate in peptidoglycan synthesis. Concentrations required for 50% inhibition of peptidoglycan synthesis were less than 0.1 mug/ml for diumycin and i...
The antimicrobial activity of 8 Bacillus spp. and 2 Lysinibacillus spp. representing the predominant aerobic sporeformers during traditional maari fermentations, a traditional fermented baobab seeds product from Burkina Faso, was investigated. The antimicrobial activity was assessed against a total of 31 indicator organisms representing various Gram-negative and positive pathogens. The screenin...
E"citracin is an antibacterial substance discovered by Johnson, Anker, and Meleney (1945) in culture filtrates of the so-called Tracy strain of Bacillus subtilis. The toxicity of the drug and its absorption and excretion in dogs have been described by Scudi and his coworkers (Scudi and Antopol, 1947; Scudi, Clift, and Krueger, 1947). The blood levels obtained after the intramuscular administrat...
This work investigates the problem of determining switching conditions for the production of the lantibiotic subtilin by Bacillus subtilis. These conditions are synthesized as the outcome of an optimal control problem based on a survival analysis interpretation. The problem is built upon the general modeling framework of stochastic hybrid systems, by translating the survival analysis into a pro...
