ABSTRACT
A microbial screening indicated that two fungal strains, Beauveria bassiana DSM 1344=ATCC 7159 and Cunninghamella elegans DSM 1908=ATCC 9245, as well as four bacterial strains belonging to the genus Streptomyces were able to hydroxylate 4,5-dianilinophthalimide (DAPH, CGP52411) to 4-(4'-hydroxyanilino)-5-anilinophthalimide. Cunninghamella elegans DSM 1908 turned out to be the most active biocatalyst and was also able to form the dihydroxy derivative, 4,5-bis(4'-hydroxyanilino)phthalimide. The reaction for the monohydroxylated biotransformation product was carried out on a preparative scale, and the culture conditions for the formation of 4-(4'-hydroxy- anilino)-5-anilinophthalimide with this strain were op-timized.
