第五章 微生物与发酵工程（The fifth chapter, microbiology and fermentation engineering） A group of microorganisms, nutrition, metabolism, and growth Review your suggestions 1., the microbial population can be divided into the following aspects: To fully tap the knowledge of the connotation and denotation, pay attention to strengthen the extension and expansion of knowledge. Such as: a case of bacteria, can review the composition of the plant cell wall, grana can contact in gene engineering as a carrier of the grana, colony population and community characteristics of contact, contact the pneumococcus bacteria in the experiment of two kinds of transformation. In the case of a virus, the species and characteristics of the virus can be considered, and the principle of phage infecting bacteria is concerned. 2. the nutrition, metabolism and growth of microorganisms should be compared with the nutrition, metabolism and growth of higher animals and plants. Can be compared from the following aspects: (1) nutrition: list comparison. There is a unity of nutrition between them. (2) metabolism: metabolic processes, metabolism and regulation review three higher animal nutrition (nervous regulation and humoral regulation); plant mineral nutrition, water metabolism, photosynthesis, respiration and other products and adjust the process; the products of microbial metabolism, regulating process. (3) growth: biological growth, from the point of view of cells, is the increase in cell number, cell volume increases. But the number of higher organisms and microbial cell proliferation in different ways, higher organisms by mitosis, proliferation of microbial diversity, two cases of bacterial division, actinomycetes spore reproduction, virus fission etc.. From the point of view of metabolism, growth is more complex than catabolism, and more and more biological accumulation substances. Microbial population growth was studied in a laboratory fixed volume liquid medium. The main environmental factors affect
