Yogurt is one of many types of fermented milk that is consumed around the world.All are prepared by culturing certain lactic acid bacteria found in milk,but the fermented product differs in name taste depending on the of milk used and the type of lactic acid bacteria that accomplish the fermentation .Commercial yogurt in North America is made from cow's milk and is prepared under controlled conditions in two steps,each at a temperature that favors the metabolism and growth of different types of lactic acid bacteria.
In the first step of milk fermentation,the milk is held at 46-48摄氏度 which encourages the growth of Streptococcus thermophilus.This organism rapidly ferments lactose (milk sugar) to lactic acid.Lactose is a disaccharide composed of glucose and galactose which are connected by a glucosidic bond.Lactose is transported into the and the glucosidic bond is broken by the enzyme β-galactosidase .After the lactose is broken into galactose and glucose,both sugars are converted to glucose-6-phosphate.Then,S.thermophilus oxidizes glucose-6-phosphate to lactic acid using the Embden-Meyerhoff-Parnas(EMP) pathway.
Genetically modified organism(GMO) means an organism in which the genetic material has been altered in a way that does not occur naturally by mating and/or natural recombination.A food produced using gene technology means a food which has been derived or developed from an organism which has been modified by gene technology,and gene technology is defined as meaning "recombinant DNA techniques that alter the heritable genetic material of living cells or organisms".
Biosafety of transgenic plants is indeed an important issue to be considered.We have conducted the experiment for evaluating the safety of transgenic sweet pepper and tomato collaborating with medical doctors for a year long.Feeding test results show that there are no significant differences on growth rate,food consumption coefficiency,blood systems,function of lives and kidneys,reproductive systems and the metabolism of protein,fat and sugar between rats fed with transgenic food and non-transgenic food.Mutation test again shows no aignificant different,which is similar to many labs findings.Therefore,international collaboration and understanding of the importance of agrobiotechnology are significant.

您好,很高兴为您解答!望采纳!
朋友,您的这篇文章里有许多错的单词,我都在下列译文中表示出来了!
酸奶是许多类型的发酵的牛奶是消耗环游世界.所有准备通过培养一定的乳酸菌牛奶中发现的,但不同的名字品尝发酵产物视牛奶使用的类型和乳酸菌发酵,完成.商业酸奶在北美是由牛奶的婴儿,并准备在受控条件下两个步骤,每一位在一个温度,利于代谢和生长不同类型的乳酸菌.
在第一步发酵的牛奶,牛奶,鼓励举办的增长46-48摄氏度链球菌.这个生物快速发酵乳糖过敏)乳酸.特别是二糖乳糖组成的葡萄糖和乳糖的glucosidic之间通过一个债券.乳糖运入和glucosidic债券将被酶β-galactosidase. 在乳糖分解为乳糖、葡萄糖、都被转换成glucose-6-phosphate.Then糖,年代. thermophilus氧化glucose-6-phosphate使用Embden-Meyerhoff-Parnas为乳酸(EMP)的路子.
转基因生物(转基因)意味着一个有机体的遗传物质发生改变,不发生自然地被交配和/或自然的重组.一个食品生产技术是指利用基因食品,推导得到了从一个有机体或开发已经过基因技术、基因技术的定义是:意思是“重组DNA技术,改变遗传基因材料的活细胞或生物体”.
转基因植物的生物安全性确实是一个重要的问题要考虑.我们进行了实验的安全性评价和番茄转基因的甜椒联合医生一年之久.喂养试验结果表明,均无显著性差异对生长速率、食品消费系数、血液系统、功能的生命及肾脏、生殖系统.
IBC传送系统提供了一种填充定位和/或连接IBC Matcon对任何一种粉过程的开销.1美元__VE_ITEM__系统框架,包括国际广播中心(IBC)位置保证正确地定位的国际广播中心(IBC)用于填筑.采用螺栓在地板上,有四个锥角的指南.1美元的框架__VE_ITEM__生产不锈钢304级学生对Matcon EF1完成.讯框会被架在四负荷细胞和装有隔振器.讯框会被配备一个自动钳系统停靠在锥阀在国际广播中心(IBC).该系统保证了锥阀是安装正确开始填充前,从而减少偶然的机会,泄漏或溢出.控制系统坐落在一个外壳,适合墙或框架安装毗邻
