The effects of six effectors , polyethylene glycol ( peg ) 6000 , d - sorbitol , trehalose , dithiothreitol , glycerol and glutarie dialdehyd on pal activity in enzymatic reaction were investigated in this article 摘要实验考察了聚乙二醇6000 、 d -山梨醇、海藻糖、二巯基苏糖醇、甘油、戊二醛对酶反应中苯丙氨酸解氨酶活力的影响。
By response surface experiment , it was found that the combination use of 0 . 54 % peg6000 , 0 . 62 % trehalose and 0 . 31 % dtt could effectively improve the pal activity by 92 . 9 % 响应面实验发现，海藻糖、聚乙二醇6000 、二巯基苏糖醇在实验浓度范围内交互作用很小， 0 . 62 %海藻糖、 0 . 54 %聚乙二醇6000和0 . 31 %巯基苏糖醇的组合可提高酶活92 . 9 % 。
Mercury transferred from low molecular weight proteins to high molecular weight ( 1 . 0 106da ) proteins after treatment by selenocysteine . mercury can not be replaced by the complexing reagent of dithiothreitol , sodium diethyl - dithiocarbamate and selenocysteine 高分子量蛋白质经还原剂二硫苏糖醇作用后，部分蛋白质的分子量降低，但在这部分蛋白质中只含有很少量的汞和硒。
Some recent developments and some main products produced from bagasse , such as ethanol , xylitol , feed of animal , enzymes , edible fungi were reviewed , and the researches and utilizations of bagasse resources in the near future were discussed 摘要对国内外利用蔗渣生产乙醇、木糖醇、动物饲料、酶制剂、食用菌等生物产品的研究进展进行了综述，并对今后蔗渣资源的研究和利用提出一些看法。
On the basis of single factor experiment , 3 factors 3 levels orthogonal experiment was adopted to study impact of bean dregs powder , linseed oil , xylitol syrup on peel quality and tea powder , bean dregs powder , butterine on stuffing quality 实验在单因素基础上采用3因素3水平正交实验研究了豆渣粉、亚麻油、木糖醇糖浆对月饼皮品质的影响以及茶粉、豆渣粉、人造奶油对月饼馅料品质的影响，并对其理化指标，营养素组成进行分析。
This article summarized the biodegradation process of main components of wood in nature and the research situation , the facing problem and the progress tendency of bioconversion to useful products using wood residue , including bioconversion to ethanol , single cell protein , xylitol and lactic acid 本文综述自然界中木材各成分的生物分解过程，以及木材剩余物的生物转化技术，包括生物转化乙醇、单细胞蛋白、木糖醇、乳酸等的研究现状、存在问题及发展趋势，为木材剩余物的应用研究提供理论基础。
Through pathway of orientated degradation or decomposition of lignocellulosic biomass , many high - value organic substances of small molecules such as glucose , xylose , phenylpropane units and their dimers , gaseous substances such as ch4 and co , liquid substances such as organic acids , aldehydes , alcohols and other platform chemicals such as furfurals , levulinic acids , xylitols and ethanols can be produced 木质生物质通过一定的降解或分解途径，可产生很多有重要价值的有机小分子化合物，这些有机小分子化合物有葡萄糖、木糖、苯丙烷单体及二聚体，气态小分子如ch4和co ，液态小分子如有机酸、醛、醇，重要基础平台化合物糠醛、乙酰丙酸、木糖醇、乙醇等。
Usage : it is the intermediate of human body sugar suppression , it could be absorbed by organize through cell membrane when the human body lacks of the insulin promotion , and could promote the liver glycogen synthesize , improve the liver function , it is the ideal medicine for the diabetic and hepatitis complication ; at the same time , it is not used by the bacterium that could bring about dental caries in the oral cavity , it could prevent the dental caries ; it could be used in food , healthy food , medicine , and light industry broadly 是人体糖代谢的中间体，在人体缺少胰岛素促进的情况下，木糖醇也能透过细胞膜被组织吸收利用，并能促进肝糖元合成，改善肝功能是糖尿病和肝炎并发症病人的理想药物；同时，本品不被口腔中产生龋齿的细菌所利用，能防止龋齿；广泛用于食品，保健品，医药，轻工等
