ABSTRACT

In this review we restrict ourselves to bacteria that are derived from soil and exert the positive effect on the plants, such microbes are by and large assigned as PGPR (plant growth - promoting rhizobacteria). The beneficial effects of those rhizobacteria on plant growth are often direct or indirect. To apply their helpful impacts, microscopic organisms (bacteria) typically should colonize the premise surface productively. They help in providing nitrogen, increase supply of other nutrients, produce plant hormones, enhance other beneficial bacteria or fungi, control bacterial and fungal diseases and help in controlling insect pest. These bacteria are not simply additional elements to biological diversity within the rhizosphere but are essential components to the survival of other microorganisms and plants. PGPR helps plant that results in plant growth stimulation, plant protection as well as production of antibiotics, geochemical cycling of minerals and plant colonization. Keywords: PGPR, Pseudomonas aeruginosa, Bacillus subtilis, growth promotion
