In the research for new antitumor substances produced by Streptomyces especially active against Ehrlich ascites carcinoma, the authors isolated a new strain No. 48-B-3 from the soil of Akihabara, Tokyo. This strain produces a substance which shows a specific activity against Ehrlich ascites carcinoma and Yoshida sarcoma.
