title: Antibiotic DE-3936, a polyether antibiotic identical with lonomycin. Taxonomy, fermentation, isolation and characterization.
abstract: Antibiotic DE-3936 was isolated from the fermentation broth of a streptomycete No. 9735-1, which is identified as a strain of Streptomyces hygroscopicus. The antibiotic is a hydrophobic compound having the molecular formula of of C44H75O14Na and is  active against Gram-positive bacteria, mycobacteria, mycoplasma and protozoa, especially coccidia. Its chemical and biological properties indicate that antibiotic DE-3936 belongs to the group of polyether antibiotics and is identical with lonomycin.
