Figure 1

Flowchart for isolation of antibiotic no. 70. Antibiotic no. 70 was isolated from culture broth of the producer IMV-70 by extraction methods. The flowchart for the extraction that produces the powder preparation of compound no. 70 is shown in Figure 1. The antibiotic no. 70 was isolated from culture broth by extraction with ethyl acetate, was subsequently purified from the inactive lipid fraction, and was extracted from the concentrated solution with hexane.
