1 Domestication of Microbes – Applied and Industrial Microbiology • Empirical biotechnology: microbial processes used long (>5000 years) before development of microbiology as a science • Louis Pasteur 1857 Microbiology of lactic acids fermentations 1860 Role of yeast in ethanolic fermentation • advances in applied microbiology led the development of microbiology Selman Waksman (~1945) “There is no field of human endeavor… …where the microbe does not play an important and often dominant part.” remnants of a fermented drink in fragments of 9,000-year-old Chinese vessels Applied Microbiology – Putting Microbes to Use • Use and control of microorganisms for the benefit of mankind use of microorganisms to make product: e.g. food, chemical, enzyme, etc. control of organisms because they cause food spoilage, disease or other biodeterioration Biotechnology - Microbial technology • the use of living organisms to produce products beneficial to mankind • the application of biological organisms, systems or processes in industrial & technical processes

2 1. Food and beverage biotechnology • fermented foods, alcoholic beverages (beer, wine) •f lavo rs 2. Enzyme technology • production and application of enzymes 3. Metabolites from microorganisms • amino acids • antibiotics, vaccines, biopharmaceuticals • bacterial polysaccharides and polyesters • specialty chemicals for organic synthesis (e.g., chiral “synthons”) 4. Biological fuel generation • ethanol or methane from biomass, single cell protein, production of biomass • microbial recovery of petroleum 5. Environmental biotechnology • water and wastewater treatment • composting (and landfilling) of solid waste • biodegradation/bioremediation of toxic chemicals and hazardous waste 6. Agricultural biotechnology • soil fertility • microbial insecticides, plant cloning technologies 7. Diagnostic tools • biosensors Microbial Applications and Products Control of Microorganisms 1. Preventing food spoilage • sterilization methods, canning • water activity, acidity, pickling, etc. • fermented foods 2. Sanitation, prevention of waterborne disease • disinfectants, antiseptics, etc. • water treatment (filtration, chlorination…) • wastewater treatment 3. Prevention of biodeterioration • buildings and structures (e.g. mold)

5 Primary metabolites: Primary vs. Secondary Metabolism Secondary metabolites: • produced during active growth • generally a consequence of energy metabolism and necessary for the continued growth of the microorganism Substrate A Product Substrate A B C Product • ethanol, lactic acid,… • synthesized after the growth phase nears completion
