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