Glysperin, a new antibiotic complex of bacterial origin I. production, isolation and properties

Abstract

Strains of Bacillus cereus produced a complex of new antibiotics, glysperins A, B and C. They are basic, water-soluble antibiotics and active against Gram-positive and Gram-negative bacteria including aminoglycoside-resistant organisms. Glysperin A is a major component of the antibiotic complex and approximately two to four times more active than components B and C. © 1981, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION. All rights reserved.
