ph optimum meaning in English

ph最适值

Its cell wet weight increases in 72h and then keeps constant . studies on the partial enzyme characters of recombinant phytase showed that the recombinant phytase had two ph optima ( 2 . 5 - 3 . 0 and 5 . 0 - 5 . 5 ) and a temperature optimum 55 , and with higher activity under the ph ranged from 4 . 5 to 6 . 0
重组植酸酶部分酶学性质的研究结果表明:重组酶在ph值2 . 5一3 . 0和5 . 0一5 . 5时酶活性最高，且在ph4 . 5一6 . 5之间均有较高的酶活性，最适作用温度为55 。
Escherichia coli phytase appa is an alternative enzyme with performance advantages over the conventional a . niger enzyme . the appa phytase displays several favorable characteristics : an acidic ph optimum close to the physiological ph range of the stomach of pigs and chickens , higher affinity to sodium phytate , greater resistance to pepsin than the commercially available a . niger phya , and higher catalytic efficiency for phytate than that of all other known phytases
大肠杆菌来源的appa植酸酶是一种新型的植酸酶，与常规的黑曲霉植酸酶相比具有许多优点，如与猪、鸡等畜禽胃的ph环境更加适应，与底物植酸更强的亲合性以及对消化道蛋白酶更强的抵抗性。
