The field of bacterial genetics has been restricted for many years to
Escherichia coli and a few other genera of aerobic or facultatively
anaerobic bacteria such as Pseudomonas, Bacillus, and Salmonella. The
prevailing view up to recent times has been that anaerobic bacteria are
interesting organisms but nothing is known about their genetics. To most
microbiologists, anaerobic bacteria appeared as a sort of distant
domain, reserved for occasional intrusions by taxonomists and medical
microbiologists. By the mid-1970s, knowledge of the genetics and
molecular biology of anaerobes began to emerge, and then developed
rapidly. but also im- This was the result of advances in molecular
biology techniques, portantly because of improvements in basic
techniques for culturing anaerobes and for understanding their
biochemistry and other areas of in- terest. Investigations in this field
were also stimulated by a renewal of interest in their ecology, their
role in pathology and in biotransformations, and in the search for
alternative renewable sources of energy. The initial idea for this book
came from Thomas D. Brock. When Dr. Brock requested my opinion about two
years ago on the feasibility of publishing a book on the genetics of
anaerobic bacteria, as a part of the Brock/Springer Series in
Contemporary Bioscience, I answered positively but I was apprehen- sive
about assuming the role of editor. However, I was soon reassured by the
enthusiastic commitment of those I approached to contribute. Eventually,
thanks to the caring cooperation of the contributors, the task became
relatively easy.
