Chapter 1: the evolution of microorganisms and microbiology. The development of industrial microbiology and microbial ecology: louis pasteur. Demonstrated that alcohol fermentations and other fermentations were the result of microbial activity. Developed the process of pasteurization to preserve wine during storage: sergei winogradsky (1856-1953) and martinus beijerinck (1851-1931) Developments in microbial ecology: sergei winogradsky (1856-1953) and martinus beijerinck (1851-1931) Studied soil microorganisms and discovered numerous interesting metabolic processes (e. g. , nitrogen fixation) Pioneered the use of enrichment cultures and selective media. Microbiology has basic and applied aspects: basic aspects are concerned with individual groups of microbes, microbial physiology, genetics, molecular biology and taxonomy, applied aspects are concerned with practical problems disease, water, food and industrial microbiology. Molecular and genomic methods: led to a second golden age of microbiology (rapid expansion of knowledge, discoveries restriction endonucleases (arber and smith) first novel recombinant molecule (jackson, symons, berg)
