In Environmental Biotechnology-Principles & Applications" the authors connect the many different facets of environmental biotechnology. The book develops the basic concepts & quantitative tools in the first six chapters which comprise the principles. The text consistently calls upon those principles as it describes the applications in Chapters 7 through 16. The theme is that all microbiological processes behave in ways that are understandable predictable & unified. At the same time each application has its own special features that must be understood. The special features do not overturn or sidestep the common principles. Instead they complement the principles & are most profitably understood in light of the principles."
