Environmental Role of Nitrogen-fixing Blue-green Algae and Asymbiotic Bacteria
The environmental role of asymbiotic N2-fixing blue-green algae and bacteria in aquatic habitats. The environmental role of asymbiotic N2-fixing blue-green algae and bacteria in terrestrial habitats. The environmental role of nitrogen-fixing symbiotic blue-green algae. Ecological and management aspects on nitrogen-fixing bacteria associated with non-nodulated plants.
Nitrogen Fixation by Free-Living Micro-Organisms
This 1976 volume provides information, presented at an international symposium in Edinburgh, on the free-living nitrogen-fixing bacteria and blue-green algae. In addition to information on the distribution of the nitrogenase enzyme within these groups, their role in the soil and in aquatic systems is considered, as are the methods of measuring nitrogen fixation.

Soil Nitrogen Ecology
This book highlights the latest discoveries about the nitrogen cycle in the soil. It introduces the concept of nitrogen fixation and covers important aspects of nitrogen in soil and ecology such as its distribution and occurrence, soil microflora and fauna and their role in N-fixation. The importance of plant growth-promoting microbes for a sustainable agriculture, e.g. arbuscular mycorrhizae in N-fixation, is discussed as well as perspectives of metagenomics, microbe-plant signal transduction in N-ecology and related aspects. This book enables the reader to bridge the main gaps in knowledge and carefully presents perspectives on the ecology of biotransformations of nitrogen in soil.
