内容説明

This text presents a new technique for detecting microorganisms, specifically bacteria found in all levels of the biosphere. It also discusses methods for enzymatic release of these microbes as well as their interactions in all ecosystems. Drawings and micrographs help to illustrate this concept. Part one is devoted to the mechanisms of adherence. The second part discusses microbial ecology and the bacterial population of tissues as well as both land and aquatic microbiocenoses in general. Part three specifically covers technique. What is known about the mechanisms of adherence justifies the choice of techniques suggested. Applications in areas such as nature, medicine, environmental hygiene and the food industry are discussed. The explanation of useful techniques, the author's research results, and practical application methods make this volume an essential reference tool for researchers, technicians and practitioners.
