摘　　要：动胶菌HP3分泌的胞外酶为组成酶 ,它能使溴胺酸脱色 ,其催化溴胺酸脱色的最佳作用温度为 30℃ ,pH 7 0— 7 2 .该酶在 4℃下放置时 ,活性可保持 2 4h .该酶使溴胺酸开环脱色的同时 ,有等摩尔量的邻苯二甲酸生成 ,它不能降解邻苯二甲酸 .动胶菌HP3降解溴胺酸的终产物为 2 氨基— 3 羟基— 5 溴苯磺酸钠和 2 ,3 二羟基— 5 溴苯磺酸钠 .Extracellular enzymes secreted by Zoogloea itzigohn HP3 belong to component enzymes, which could decolor ABAS and the optimum temperature and pH were 30℃ and 7 0—7 2 respectively. The activity of the extracellular enzymes could preserve 24?h under 4℃. The enzymes could cleave ABAS and o phthalic acid were formed stoichiometrically. However, o phthalic acid could not be degraded by the extracellular enzymes. The products of ABAS degraded by Zoogloea itzigohn HP3 were sodium of 2 amino—3 hydroxyl—5 bromobenzenesulfate and sodium of 2,3 dihydroxyl—5 bromobenzenesulfate
