The osmolality of rhizosphere soil water is expected to be elevated in relation to bulk-soil water osmolality as a result of the exclusion of solutes by plant roots during water uptake, the release of plant root exudates, and the production of exopolymers by plant roots and rhizobacteria. In contrast, the osmolality of water within highly hydrated bulk soil is low (less than 50 Osm/kg); thus

For isolation of rhizosphere bacteria, 1.0 gram of the soil was mixed in 9.0 ml of saline solution (0.9% NaCl) (w/v). The soil suspension was vortexed for five minutes to remove soil, stones, debris and dead bacterial cells. For isolation of root adhering (rhizoplane) bacteria fresh roots were washed using distilled water. bacteria do not effect the germination of tobacco seeds.

The root microbiota is critical for agricultural yield, with growth-promoting bacteria able to solubilise phosphate, produce plant growth hormones, antagonise pathogens and fix N 2.Plants control the microorganisms in their immediate environment and this is at least in part through direct selection, the immune system, and interactions with other microorganisms.

The rhizosphere effect is different for different microbes that are present in the rhizosphere. Its value ranges from 5 to 20.

rhizosphere bacteria are the result of the direct action of antagonists on plant pathogens, through antibiosis, predation or parasitism, induced resistance of the host plant, and direct competition for space and limited resources (Ahemad and Khan 2010Janisiewicz et al., 2000).
