title: ETHYLATION: BIOLOGICAL FORMATION  OF AN S-ETHYL HOMOLOG OF LINCOMYCIN.
abstract: Streptomyces umbrinus var. cyaneoniger produces the antibiotic lincomycin. When grown in the presence of ethionine an additional antibiotic is produced. Physical and chemical analyses and incorporation of radioisotopes indicate that the new antibiotic is the S-ethyl homolog of lincomycin.
