1) The growth of Penicillium sclerotiorum NRRL 2074 reached its maximum in 10 days while the maximum carotene formation was attained in 15 days. 2) Light had a marked stimulative effect on the carotene production. 3) Shaking during the incubation period has a deleterious effect on the carotene formation. 4) Czapek-Dox agar was good for the growth but was inferior to wort agar in the carotene formation. 5) P.sclerotiorum NRRL 2074 produced about 1 mg of total carotene per gram of mycelium dry weight, of which approximately 65% was β-carotene and approximately 25% was γ-carotene. In addition, as minor pigments, α-carotene, 3-cis-isomers of β-carotene, 2-cis-isomers of γ-carotene, and zeacarotene were identified.
