Abstract:
Generally, forests represent largely productive or regenerative habitats that act as carbon storage systems. In such habitats the organic matter of soil is formed as a result of decay of biomass residue along with the carbon that is deposited in the rhizosphere. Forests represent a high position of spatial diversity. Fungi, bacteria and archaea inhabit various forests. Bacillus and Pseudomonas species are well known for effectively solubilizing nutrients that limit plant growth like phosphate and potassium which ultimately improved plant growth. These bacteria colonize the plant rhizosphere and increase the plant growth by various mechanisms. The use of beneficial microorganisms as biofertilizers is increasing in agriculture and also helps to replace or reduce chemical-based fertilizers as well as pesticides usage. In the present study, Pseudomonas fluorescens were isolated and characterized from the soil samples of naturally regenerative ecosystems like forests in order to identify fluorescent pseudomonad isolates which are well known as plant growth promoting rhizobacteria.
