Glycocinnamoylspermidines, a new class of antibiotics. I. Description and fermentation of the organism producing the LL-BM123 antibiotics.

Abstract
The producing organism for the new borad spectrum glycocinnamoylspermidine antibiotics designated LL-BM123 .beta., .gamma.1 and .gamma.2 was characterized as a Nocardia sp. by chemical analysis of the cell wall, growth requirements, morphology and physiological reactions. Fermentation conditions to elaborate and analytical methods to characterize these antibiotics in fermentation filtrates are described.
