  2. microbial diversity and habitats habitat diversity unique C and E sources metabolic strategies fermentation  respiration heterotrophy  phototrophy symbioses ruminants mycorrhizae extreme environments pH temperature salinity pressure

  3. biogeochemical cycling: the carbon cycle

  4. biogeochemical cycling: the nitrogen cycle

  5. nitrogen fixation

  6. biogeochemical cycling: the sulfur cycle

  7. life without sunshine SO42– H2S

  8. microbial decomposition

  9. composting & bioconversion

  10. Chapter 27 learning objectives • Discuss the metabolic strategies and environments that make microbes more versatile than multicellular organisms. • Discuss the roles of bacteria in nitrogen, carbon and sulfur cycling. What are the basic steps in these processes? • Who fixes nitrogen, and why are there so few types of organisms that do? • Discuss the role of the chemoautotroph in extreme environments. • Define and discuss bioremediation and bioaugmentation. • Discuss composting and bioconversion. Contrast the different types of fuels made during bioconversion.

  11. Chapter 28

  12. -glucuronidase - galactosidase ONPG MUG fluorescent compound ONP (yellow) microbial water pollution

  13. food preservation

  14. microorganisms in food production

  15. bioreactors

  16. industrial products

  17. Chapter 28 learning objectives • How are microorganisms used to indicate water pollution? • Generally, how are foods treated to avoid spoilage? • How are microbes involved in cheese, bread, alcohol and thickener production? • How are microbes used in industry? • Discuss primary and secondary metabolites and how the terms bioreactors, trophophase and idiophase relate to the production of these metabolites.
