Combines the work of 21 international experts in ecological enzymologySurveys the intra- and extra-cellular behavior of enzymes in soils and aquatic systemsDiscusses microbe-plant symbioses, controlling plant pathogens, and organic matter decomposition and its impact on local and global carbon and nitrogen cyclesExplores detection applications, such as assessing nutrient turnover, soil health and the presence of plant pathogens, and the progress of remediation of polluted soils and waters
The need to understand the biological processes that are important for essential aquatic and terrestrial ecosystem function has prompted much research into the field of ecological enzymology. This book presents the two broad areas of application in a compilation of reviews by 21 international experts in their respective fields. The first explores enzymatic activities to assess the processes or mechanisms that operate in a given system, such as the rhizosphere, plant leaves and shoots, soil surfaces, and biofilms. The second considers enzymes or microbial cells as sensors to detect microbial activity and stresses due to pollution, management, or climatic change in both aquatic and terrestrial ecosystems.

"...highly complex environments are excellent[ly] illustrated in this book. .... 'Enzymes in the Environment' [is] equally recommended to the soil and environmental scientists, biochemists, enzymologists, microbiologists, toxicologists, geneticists, agriculturists, as well as to undergraduate and graduate students in all these scientific areas."
