[Eremomycin--a new antibiotic from the cyclic glycopeptide group].

Eremomycin, a novel antibiotic belonging to the group of cyclic glycopeptides is produced by an actinomycete designated INA-238. Biosynthesis, isolation, physico-chemical and biological properties of the antibiotic are described. Eremomycin is shown to be close to vancomycin.

[New species of actinomycete Streptomyces variegatus sp. nov. synthesizing an antibiotic of the alpha-hydroxyketopentaene group].

Stroptomyces strains INA T-511 and INA 3946 were isolated from 2 different soil samples. Both the strains produced an antibiotic of the group of alpha-hydroxyketopentaenes. The antibiotic was active against gram-positive bacteria, yeasts and fungi belonging to Penicillium.
