The study of biofilm considers the close association of micro-organisms at interfaces and the consequent physiological adaptations to the proximity of other cells and surfaces. As such, it is relevant to a variety of disciplines, including medicine, dentistry, bioremediation, biofouling, water technology, engineering, and food science. Although the habitats studied and their associated cellular communities differ widely, some common elements exist such as method of attachment, coadhesion, regulation of biofilm phenotype, and biofilm architecture. This book aims to distil the common principles of biofilm physiology and growth for all interested disciplines. This volume will appeal to the specialist as well as the student.
