Abstract
A survey of carotenogenic activity of 72 fungus strains were conducted. In addition to the strains known as carotene producers, Penicillium sclerotiorum, P.multicolor, P.lapidosum, and Rhisoctonia sp. Y-08 were found to produce carotene when grown on Difco wort agar media. P.sclerotiorum NRRL 2074 produced about 0.7 mg total carotene per gram of dry mycelium and its major pigments were β- and γ-carotene.
