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.
微生物筛选表明,两种真菌菌株,白僵菌 DSM 1344=ATCC 7159 和 Cunninghamella elegans DSM 1908=ATCC 9245,以及属于链霉菌属的四种细菌菌株能够羟基化 4,5-二苯胺邻苯二甲酰亚胺(DAPH,CGP52411)至4-(4'-羟基苯胺基)-5-苯胺基邻苯二甲酰亚胺。 Cunninghamella elegans DSM 1908 被证明是最活跃的生物催化剂,并且还能够形成二羟基衍生物 4,5-双(4'-羟基苯胺基)邻苯二甲酰亚胺。单羟基化生物转化产物的反应以制备规模进行,并优化了该菌株形成4-(4'-羟基苯胺基)-5-苯胺基邻苯二甲酰亚胺的培养条件。
