It was recognized that the yellowish brown viscous sirupy substance, which was obtained by extracting the bacterial cells of B. teres var. antibioticus grouw in the sngar containing broth with ether, has antibiotic action for various GRAM-positive and negative bacteria. This antibiotic substance is soluble in ether, chloroform, benzol and plant oil, hardly soluble in 90% ethanol and 90% methanol and insoluble in water, acetone and butanol. This subtance is not adsorpted with active carbon and heating at 100°C during 30 minutes has no effecton the antibiotic action. We have recognized that this substance is not haemolytic and shows no poisonous action on mice. This substance resembles Biocerin among the already known antibiotics.
