title: [Biological properties of a Bacillus brevis 101 mutant].
abstract: Some features of the Bacillus brevis 101 mutant producing the antibiotic gramicidin S are described. The mutant is very close to the initial P+-variant of Bacillus brevis var. G-B by cultural, physiological and biochemical characteristics. The most typical features of Bacillus brevis 101 are high antibiotic activity (up to 2 g/l) and the specific phenotype of the colonies. The phenotypical features of Bacillus brevis 101 are dependent on the conditions of its cultivation. On minimal media rich in organics a change of the culture correlated with a lower antibiotic activity.
