Industrial Microbiology and Fermentation Technology Industrial Microbiology is the discipline that uses microorganisms, usually grown on a large scale, to produce valuable commercial products or carry out important chemical transformations. Fermentation Technology is the technology to grow cells in large scale with high efficiency, it also includes product recovery processes

1.正确识别各种类型茎 2.正确识别各种类型变态茎 3.区别攀援茎与缠绕茎、匍匐茎和平卧茎 4.茎在外形上与根的区别 5.解释概念:树皮周皮

病毒性皮肤病是由病毒感染所致的皮肤粘膜病变。根据病毒 性皮肤病的不同临床表现特点,可将其分为新生物型、疱疹 型、红斑发疹型。单纯疱疹是由单纯疱疹病毒感染所致的病 毒性皮肤病。皮疹以群集性小水疱为特征,能引起多种部位 感染,但以口周、鼻腔、生殖器等处好发。病程有自限性

一、基本概念 1、代谢动力学( toxicokinetics):用数学方法研究毒物的吸收、分布、生物转化和排泄等代谢过程随时间变化的规律。 目的:了解毒物在体内的消长规律,为毒物的安全性评价提供依据

一、实验目的 明确培养基的配制原理;通过对基础培养基的配制,掌握配制培养基的一般方法和步骤。学习高压蒸汽灭菌的操作方法;学习干热灭菌的操作技术

一、两性生殖 Bisexual reproduction Eggs usually begin meiosis(减数分裂) only after fertilization. The meiosis of sperms have stopped before the fertilization

1. INTRO We all suffer in writing, one way or another. We have trouble writing or we get writer's block. But there are ways to go at it that are less painful. a. Divide and conquer the rules of writing. Taking them one at a time will make learning the rules earlier. i. We'll keep nagging you on your writing. Take the time to go over the comments we write on your papers

1.单细胞植物,一个细胞代表了一个个体,一切生命活动,包括新陈代谢、 生长发育、繁殖,均由一个细胞完成。复杂的高等植物,一个个体由无数 细胞组成,细胞之间有了机能和形态结构的分工,相互依存、彼此协作, 共同保证有机体的正常生命活动

任何植物体,单细胞的藻类,到参天大树,都是通过细胞分裂,增加细胞的数目,使植物体能完成从生长发育到繁殖的整个生命过程。细胞分裂主要有三种方式:有丝分裂mitosis,无丝分裂 amitosis和减数分裂 meiosis
