Acknowledgments

I became a microbiologist in Burk A. Dehoritys 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. Im 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.

About the Author

Anne Maczulak grew up in Watchung, New Jersey, with a plan to become either a writer or a biologist. She completed undergraduate and

masters studies in animal nutrition at The Ohio State University, her doctorate nutrition and microbiology from the University of Kentucky, and conducted postdoctoral studies at the New York State Department of Health. She also holds an MBA from Golden Gate University in San Francisco.

Anne began her training as a microbiologist studying the bacteria and protozoa of human and animal digestive tracts. She is one of a relatively small group of microbiologists who were trained in the Hungate method of culturing anaerobic microbes, meaning microbes that cannot live if exposed to oxygen. In industry, Anne worked in microbiology laboratories at Fortune 500 companies, developing anti-dandruff shampoos, deodorants, water purifiers, drain openers, septic tank cleaners, and disinfectantsall products that relate to the world of microbes. She conducted research in the University of California-San Franciscos dermatology group, testing wound-healing medications, antimicrobial soaps, and foot fungus treatments.
