      The main difference between symbiotic and non symbiotic nitrogen fixation is that the symbiotic nitrogen fixation is a function of nitrogen-fixing bacteria that live in symbiotic relationships with the host pants whereas the non symbiotic nitrogen fixation is a function of free-living bacteria in the soil.. Symbiotic and non-symbiotic nitrogen fixation are two types of biological nitrogen. Rhizobium can be pathogenic as well as non-pathogenic. The pathogenic Rhizobium bacteria species include: Rhizobium rhizogenes– It is also known as Agrobacterium rhizogenes and is responsible for infectious hairy roots in dicotyledonous plants.; Rhizobium radiobacter– It is also known as Agrobacterium tumefaciens and is responsible for crown gall disease.

These single-celled organisms live in fresh, brackish (combined salt and fresh water), and marine water. These organisms use sunlight to make their own.

The physico-chemical changes in the environment may affect particular species and induce the growth and abundance of other species, which leads to the succession of several species in a course of time (Muthukumar et al., ).

High temperatures favour both the phytoplankton productivity and blue green algae (Roger and Reynaud, ). The nitrogen fixing ability of the blue green algae increases in higher plants. They produce more number of heterocysts. Nitrogenous substances regularly pass from the alga to the higher plant and carbohydrates pass from plant to cyanobacteria.

Therefore, it may be called a symbiotic association. The symbiotic nitrogen-fixing bacteria invade the root hairs of host plants, where they multiply and stimulate formation of root nodules, enlargements of plant cells and bacteria in intimate association.

Within the nodules the bacteria convert free nitrogen to. In combining the nitrogen-fixing and photosynthetic modes of nutrition, blue-green algae resemble root nodule-bacteria symbiotic system. However, in the latter, the seat of photosynthesis (in the green aerial parts) and nitrogen fixation (in the root nodules) are separated in space if we regard the whole system as a composite organism.

This chap- ter describes methods of sample collection, enrichment, and isolation. Culture methods for one of the fast-growing aerobic N2-fixing marine Synechococcus species are also described.

ENVIRONMENTAL-PHYSIOLOGICAL INTERACTIONS IN LICHENS Article. the role of nitrogen fixation in nature presented a unique opportunity to: 1) compile the rates of fixation given for different portions of terrestrial and aquatic systems, 2) attempt to integrate the data on a broader basis, and.

Biological nitrogen fixation takes many forms in nature from the 1) symbiotic forms including blue-green algae (nostoc), 2) lichens, actinomycetes, non legume 3) associative symbiosis and the 4) and free-living soil bacteria.
