Isolation of a new peptide antibiotic complex 61-26. Studies on antibiotics from the geneus Bacillus. V.
A new antibiotic named 61-26 active against gram-positive bacteria and some fungi was isolated from a Bacillus strain. The antibiotic is a weakly basic peptide slightly soluble in aqueous alcohols. An approximate empirical formula of C50H93N11O17 and constituent amino acids of aspartic acid (1 mole), serine(2 moles), alanine (2moles), and sum of valine and isoleucine (2 moles) are indicated.
