The feasibility of exploiting microorganisms to produce more environmentally friendly anthraquinone dyes was investigated. A fungal culture, Curvularia lunata , was identified as producing an anthraquinone biochromophore composed of over 70% cynodontin (1,4,5,8‐tetrahydroxy‐3‐methylanthraquinone). Cynodontin of this purity was considered to be a suitable dyestuff intermediate and a method for dye production is described. Properties of the biodye were compared with those of Disperse Blue 7, the chemically synthesised equivalent. ©1997 SCI
