Zusammenfassung:The invention relates to a microbial process for the production of immunosuppressive cyclosporine antibiotic complex or of its components, cyclosporine A, cyclosporine B and cyclosporine C, by the aerobic fermentation of a filamentous fungus strain biosynthesizing the above antibiotic(s) in a nutrient medium containing utilizable carbon and nitrogen sources as well as mineral salts, and by isolating the products formed, which comprises culturing a strain of the novel Tolypocladium varium fungus species producing the cyclosporine antibiotic complex, preferably tolypocladium varium sp. nov. CY/93, deposited at the National Collection of Agricultural and Industrial Microorganisms, Budapest, Hungary under the number NCAIM(P)F 001005, on a nutrient medium containing carbon sources, organic and inorganic nitrogen sources as well as mineral salts, under aerobic conditions, at 25 DEG to 30 DEG C., and, if desired, isolating and purifying the cyclosporine antibiotic complex or its components produced.
