- 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℃, pH70—72.该酶在4℃下放置时, 活性可保持24h.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.
- Abstract: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 24h 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 amino—3 hydroxyl—5 bromobenzenesulfate and sodium of 2, 3 dihydroxyl—5 bromobenzenesulfate
