NOTES TWO NEW POLYPEPTIDE ANTIBIOTICS, CC-1014 AND CC-1014B

Abstract

In the course of a screening program for antitumor antibiotics, two new antibiotics elaborated by Paecilomyces abruptus were isolated. One of these (CC-1014) has been demonstrated to be a polypeptide, and the other is most probably a polypeptide as its properties are very similar to those of CC-1014.
