Start Plate Count of Culturable Soil Organisms

Visit the greenhouse and make notes on your selected habitat. Research how to select/enrich for particular soil bacteria. View stained total soil community photomicrographs (provided by your instructor) and do calculations to enumerate microorganisms/g wet soil through a culture independent direct count. Homework: Read all of Lab 2 & outline or make flow diagrams of your lab work in your lab notebook.
Check Resources section of wiki for information about organizing your lab notebook.
Graded Assignment: Turn in at the beginning of Lab 2, a Discussion with References of how the enrichment culture techniques and media you will use will select soil bacteria of the specific groups we seek and differentiate them from other microbes in the community.
