    as well several other educational establishments Preface


    This book is a result of the course on environmental microbiology that I taught at the


    University of Northern Iowa, Cedar Falls, Iowa, USA. The book seeks to place the


    main actors in matters of environment microbiology, namely, the microorganisms, on


    center stage. Many first degree courses in microbiology do not cover the detailed


    taxonomy of microorganisms, which facilitates their being pigeonholed into specific


    taxonomic niches in the environment. Because of this, the book looks, as much as


    possible, at the biology, especially the taxonomy, of the microorganisms.


    To this end, the taxonomy of not only bacteria and fungi, but also protozoa, algae,


    viruses and even the smaller macroorganisms, such as nematodes and rotifers, which


    are usually associated with microorganisms in aquatic and waste environments, are


    also looked at.


    Viruses are given special attention because, until recently, it was thought they


    were not important in aquatic environments; the modern understanding is that they


    are not only abundant, but play a crucial role in the sustenance of the various compo-


    nents of the biological ecosystem in aquatic environments.


    The book will be useful to a wide range of undergraduates and beginning graduate


    students in microbiology, general biology, aquatic science, public health and civil


    (sanitary) engineering. Practitioners in sanitary engineering and public health will


    also find it of interest.


    I thank my family for their encouragement.
