The metabolic activities of 3 strains (KT-303, KT-304, and KT-305) of soil bacteria were tested on tryptophan and its benzoyl derivatives (Table I), and it was found that KT-303 and KT-305 metabolized benzoyl-DL-tryptophan to produce L-tryptophan and benzoyl-D-tryptophan respectively. Two strains (KT-230 and KT-231) of soil bacteria had the activity to metabolize benzoyl derivatives of 2-aminohexanedioic acid and 2-aminooctanoic acids to yield L-2-aminohexanedioic acid, N-benzoyl-D-2-aminohexanedioic acid, L-2-aminooctanoic acid, and N-benzoyl-D-2-aminooctanoic acid respectively.
测试了 3 株土壤细菌(KT-303、KT-304 和 KT-305)对色氨酸及其苯甲酰衍生物的代谢活性(表 I),发现 KT-303 和 KT-305 分别代谢苯甲酰-DL-色氨酸生成 L-色氨酸和苯甲酰-D-色氨酸。两株土壤细菌(KT-230 和 KT-231)具有代谢苯甲酰基衍生物 2-氨基己二酸和 2-氨基辛酸的活性,分别生成 L-2-氨基己二酸、N-苯甲酰基-D-2-氨基己二酸、L-2-氨基辛酸和 N-苯甲酰基-D-2-氨基辛酸。
