Carotenoids in some ultraviolet mutants of Epicoccum nigrum link

Archiv für Mikrobiologie Aims and scope Submit manuscript

Summary

Mutants were produced by ultraviolet irradiation of the mould Epicoccum nigrum Link. The qualitative and quantitative formation of carotenoid pigments was studied. In addition to the four carotenoids present in the wild-type strain 5-I-3 several other carotenoids were isolated and identified.

The presence of these pigments is discussed. The results support the proposed pathway for the biosynthesis of rhodoxanthin, 3,3′-diketo-retro-β-carotene, from β-carotene.
