[Lambdamycin, an antibiotic from strain IMET 31118 of Streptomyces glaucoachromogenes Prauser. II. Physiochemical properties and comparison with chartreusin].

The isolation and purification of the antibiotic lambdamycin are described. The physicochemical properties of the chromoglysoide lambdamycin resemble those of chartreusin. In this paper we compare the physicochemical properties of chartreusin and antibiotic X 465 with lambdamycin (alpha D, UV, IR). Lambdamycin is identified with chartreusin.
