最适ph值 meaning in English
optimum ph
Examples
- 5 and was virtually inactive above ph 6 . 0 . when the enzyme was incubated at various ph values at 37 ? c for 30 min in the absence of substrate and the residual activity was measured , the phytase was found to be stable at the ph range of 2 to 8
该酶反应的最适ph值为5 . 5 ,在phz一6之间都有较高的酶活性, ph大于6时植酸酶的活性迅速下降,在phz一8之间的稳定性很好,活性> 70 % 。 - Preparing the lactase solution expressed in e . coli , we determinated the optimum ph , ph stability , optimum reaction tempreture , thermal stability , effect of metal ions and chemical reagent , km and vmax its optimum ph was 5 . 8 and 6 . 4 to 7 . 5 , and the optimum tempreture was 45 to 52
以onpg为底物,分别测定了其最适ph值及ph稳定性、最适温度及热稳定性、金属离子和化学试剂的影响以及k _ m值和v _ ( max )值。 - The purified enzyme was a monomeric protein whose optimum ph was 8 . 0 . inhibitor study demonstrated that it was a metalloprotease and contained sulfhydryl groups essential for catalytic activity . its activity was inhibited by divalent cations such as zn2 + , mn2 + , and the kj values of zn2 + , mn2 + were imm
这种酶温度适应范围较广,在较大温度变化区间内都具有明显的活性,但是对缓冲溶液ph值的变化却很敏感,体外以明胶为底物时最适温度为38oc ,最适ph值为8 - It was estimated that the yield of the e2 fusion protein in culture supernatant of recombinant p . pastoris could be reached 0 . 34g / l . the optimal expression conditions were explored for the ph , aeration rate , final concentration of methanol and kinds of growth media . we conclude that the higher quantity of e2 protein can be gained at ph4 . 0 - 6 . 0 , 1 % methanol as the final concentration , mm growth media and high aeration rate
通过对表达条件如ph值、通气量、诱导甲醇终浓度、培养基的选择等条件的探索,可确定猪瘟病毒hl - ly株e2基因表达的理想条件为:最适ph值在4 . 0 6 . 0之间,最适培养基为mm培养基,最佳诱导的甲醇终浓度为1 ,加大通气量时表达量较好。 - And it has not second pollution too . a strain that can grow with phenol as the sole source of carbon and energy , l3 was isolated from the waste water of yang jiabao waste water disposal factory . on the basis of observing of modality and the analysis , l3 was identified as rhodopseudomonas palustris . the optional conditions of the degradation of the phenol and the kinetics were studied with l3
通过对l3菌株在不同温度、 ph值、光照强度以及有无co _ 2条件下的生长和降解苯酚的情况分析,我们初步确定了l3的最适生长和降解苯酚的温度为30 ,最适ph值为7 . 0 ,通入一定量的co _ 2对菌株l3的生长及苯酚的降解更有利。
