    摘要: Disclosed are new Aspergillus niger mutants which can be used for identifying active FK-506/ rapamycin type, or cyclosporin A type inununosuppressants in a broth, natural product extract, or composition exhibiting inununosuppressant activity. Specifically disclosed are the new mutants, ATCC No. 74085 (MF 5659), which is sensitive to FK-506 and rapamycin but resistant to cyclosporin A; ATCC No. 74086 (MF 5659) which is resistant to FK-506, cyclosporin A and rapamycin; and ATCC No. 74087 (MF 5661) which is resistant to FK-506 and rapamycin, but sensitive to cyclosporin A.
