Acknowledgments

I became a microbiologist in Burk A. Dehority’s laboratory in 1978 studying anaerobes in cattle, sheep, and horses. From that point on I have met or worked with some of the most respected researchers in the fields of anaerobic, environmental, and water microbiology. I’m sure they have forgotten more microbiology than I ever learned, but we collectively must admit that bacteria still hold a vast world of unknowns. I thank all of my professors of microbiology at the Ohio State University and the University of Kentucky.

For this book I owe thanks to Bonnie DeClark, Dana Johnson, Priscilla Royal, Sheldon Siegel, Meg Stiefvater, and Janet Wallace for their advice on chapter content. Special gratitude is due Dennis Kunkel and Richard Danielson who always seem to offer encouragement when it is needed the most. Thanks are due to Amanda Moran and Kirk Jensen for their valuable guidance, and to Jodie Rhodes for tireless encouragement and support.
