Accordinng to the results and the regression analyses the optimal process conditions for water prehydrolysis of Euc...

用气相色谱分析了预水解液中的糖含量，结果表明：预水解液中木糖、阿拉伯糖和葡萄糖含量分别为86％、4％和10％。

The results showed that the mutant contained high trehalose content and high cell survival rate kept even after 4 h 18 %vol alcohol treatment (no respiration deficiency existed), which indicated that high trehalose content could protect cells membrane and prevent DNA loss of mitochondria and exosmosis of intracellular materials.

结果表明，中性海藻糖酶缺失突变株细胞海藻糖含量较高，用18 %vol的酒精处理4 h后仍可保持高的细胞存活率，并且无呼吸缺陷型的出现，说明高海藻糖含量可以保护细胞膜，防止线粒体DNA丢失和胞内物质的外渗，与酵母的酒精耐性之间存在一定的关系。

Fucose composed of 40% the total carbohydrate with lesser but approximately equal amount of galactose, glucosamine, and galactosamine present.

In this paper we combined three chromatographic separation and purification technique such as affinity chromatography, ion exchanger chromatography and hydrophobic interaction chromatography to develope a new technology of stimutaneous extraction of three enzyme from pancreatin. We optimized the technology by studying the methods of purification and assured the technology as: The crude extraction from the dissolution of Pancreatin is directly absorbed on the DEAE gelose fast flow columnEquilibrating buffer is 0.01mol/L NaoAc-HoAc buffer(pH4.5; eluting buffer is 0.2～0.35mol/LNaCl in 0.01mol/LNaoAc-HoAc buffer (pH4.5), and then be eluted by two steps to acquire the peak of kallikrein.The solution which can"t be adsorbed by DEAE gelose fast flow column is adsorbed on affinity chromatographic column Equilibrating buffer is 0.01mol/LTris-HCl buffer(pH7.5, eluting buffer is 0.5mol/LNaCl in 0.01mol/Ltris-HCl buffer(pH7.5)and then be eluted by one step to acquire the peak of trypsin.The solution which can"t be adsorbed by is pretreated with 30%～80%(NH_4)_2SO_4 fractional precipitation, the deposition of the precipitation is dissolved to beabsorbed on phenyl gelose fast flow columnhydrophobic interaction chromatography condition is Equilibrating buffer is lmol/L(NH_4_2SO_4 in 0.01mol/LNaoAc-HoAc buffer(pH4.5), eluting buffer is 0～0.6mol/L(NH_4)_2SO_4 in 0.01mol/LNaoAc-HoAc buffer (pH4.5) and then be eluted by two steps to acquire the peak of chymotrypsin.

本研究考察了各种纯化方法，将离子交换层析、亲和层析和疏水层析三种分离纯化法相结合，建立了激肽释放酶、胰蛋白酶和糜蛋白酶三酶的联产工艺：胰酶用pH4.5醋酸缓冲溶液提取后，粗提液直接上DEAE-琼脂糖快胶柱吸附平衡缓冲液：0.01mol／LNaoAc-HoAc缓冲液(pH4.5，洗脱缓冲液：0.01mol／LNaoAc-HoAc缓冲液(pH4.5)含0.2～0.35mol／LNaCl分两步洗脱，收集激肽释放酶的洗脱峰；DEAE-琼脂糖快胶的未吸附液上亲和层析柱分批吸附平衡缓冲液：0.01mol／LTris-HCl缓冲液(pH7.5，洗脱液：0.5mol／LNaCl溶液，一次洗脱，收集胰蛋白酶洗脱峰；最后，亲和层析未吸附液用30％～80％硫酸铵分级盐析处理，沉淀溶解后用上苯基—琼脂糖快胶吸附平衡缓冲液：0.01mol／LNaAc-HAc缓冲液(pH4.5含1mol／L(NH_4)_2SO_4，洗脱缓冲液：0.01mol／LNaAc-HAc缓冲液(pH4.5)含0～0.6mol／L(NH_4)_2SO_4，分两步洗脱，收集糜蛋白酶的洗脱峰。
