Cellulose is the most abundant natural macromolecular , which can be hydrolyzed to get energy , food and chemical industrial material 摘要纤维素是地球上最丰富的天然高分子化合物,可以通过水解的方法将其转化为为人类生产生活服务的能源、食物及化工原料。
Wide enzymatic system , plentiful enzyme quantity and appropriate proportioning of - amylase and glucoamylase were the prerequisite to the hydrolysis of crude starch 摘要酶系广泛、酶量充足、且-淀粉酶和葡萄糖淀粉酶组合恰当是促成生大米中生淀粉水解的首要条件。
Deodorant body spray : it contains hydrolytic pearls , poria alba essence , ve , vc , collagen protein and jojoba oil . it has functions of nourishing and whitening 香体露:蕴含水解的珍珠、白茯苓精华、 ve 、 vc 、胶原蛋白、霍霍巴油等多元活性,营养滋润、美白、滑爽舒适。
Research was conducted on the effect on tebufenozide hydrolysis in bodies of water of substances such as surfactants , humic acid , and no3 ( superscript - ) ions that coexist with tebufenozide in water 研究了虫酰肼降解水体中的共存物,如表面活性剂、腐殖酸和硝酸根离子等对虫酰肼水解的影响。
It is such the exquisite coupling and the distribution change between each region during the binding and hydrolyzation that make it perform the high efficiency movement 我们认为kinesin通过各部分巧妙的配合,利用atp结合和水解的过程中电荷分布的变化,充分利用电势能做功从而实现其高效率的运动。
Chemical resistance of glass used in the production of laboratory glassware - methods for determination of hydrolytic resistance of the interior surfaces of glass containers - determination by flame photometry and classification 制作实验室玻璃器皿用玻璃的耐化学腐蚀性.第4部分:玻璃容器内表面耐水解的测定方法.第2节:火焰光度测定法和分类
The amount of hydroxyacetic acid , equal to that of sodium chloride , produced from chloroacetice acid hydrolysis is determined by adopting moore method and there fore the ratio of transformation of chloroacetice acid hydrolyzed can be calculated 摘要氯乙酸水解生产羟基乙酸的工艺过程中产生等物质量的氯化钠,采用莫尔法测定氯乙酸水解的产物氯化钠,并计算氯乙酸的水解转化率,从而选择和控制水解反应的条件。
1 . a new method to identify _ amylase activity and its producing bacteria : the blue complex was formed by unspecific adsorption , after mixing starch and trypan _ blue . the adsorption weakened when the starch was hydrolyzed to small molecular by _ amylase , and the trypan _ blue was released inside the hydrolyed zone . the starch around the zone which was not hydrolyzed adsorbed free trypan - blue so that the colour of medium became bluer than that of place in hydrolyzed zone 快速鉴定并筛选-淀粉酶及其产生菌的新方法:锥虫蓝染料和淀粉由于静电非特异性吸附结合后使淀粉呈稳定的蓝色,当淀粉被淀粉酶水解后因分子变小吸附力减弱,而让锥虫蓝游离出来,游离的锥虫蓝被周围未水解的淀粉吸附而使颜色加深,淀粉水解区则形成无色、透明的水解圈。
By means of a1c13 hydrolyzing in naoh solution , the author prepared al - plms which were characterized by xrd , xrf , ft - ir , sem etc . some factors in the experiments were studied in detail . the result showed that the concentration of a1c13 , naoh , al - pillaring solution did n ' t affect the basal spacing and thermal stability of al - plms greatly 笔者采用alcl _ 3在naoh溶液中水解的方法制备了铝柱撑蒙脱石,并利用xrd 、 xrf 、 ft - ir 、 sem 、 n _ 2吸附?脱附等手段对制得的样品进行了表征,系统讨论了各实验因素的影响。
