A further characterization of Actinomyces tumemacerans KRASSILNIKOV and KOVESHNIKOV, 1962 strain INMI P-42 was carried out. It is classified in Section Monoverticillus-Spira, Series white to gray. When the organism was shakecultured in a wheat flour medium, an antibacterial antibiotic with limited antitumor activity was isolated from the culture filtrate and a tetraene antibiotic from the mycelial cake. The antibacterial antibiotic proved to be closely related to or identical with BA-180265 A (kanchanomycin) reported by Liu et al. in 1963.
