Klappentext All organisms require nitrogen to live and grow. The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms is described by the nitrogen cycle. This book is an activity of the COST 856 Action on Denitrification. It covers all aspects of the N-cycle: chemistry, biology (enzymology, molecular biology), physics, applied aspects (greenhouse effect, N-pollution problems, practices in farming, in waste-water treatment, and more). In this book, leading editors offer the latest research available on dentrification (reduction of nitrates or nitrites commonly by bacteria- as in soil). Zusammenfassung All organisms require nitrogen to live and grow. The movement of nitrogen between the atmosphere! biosphere! and geosphere in different forms is described by the nitrogen cycle. This book covers various aspects of the N-cycle such as chemistry! biology (enzymology! molecular biology)! physics! applied aspects! and others. Inhaltsverzeichnis I.
