title: Holomycin and an antibiotic (MM 19290) related to tunicamycin, metabolites of Streptomyces clavuligerus.
abstract: Streptomyces clavuligerus produces penicillin N, several cephalosporins and the beta-lactamase inhibitor clavulanic acid. The detection, isolation and properties of further metabolites of this culture, MM 21801 and MM 19290, are described. MM 21801 was identified as the antibiotic holomycin. MM 19290 was shown to be related to tunicamycin, an antibiotic complex obtained from cultures of Streptomyces lysosuperificus.
