Abstract: 

Soil is the utmost important in agriculture practices as it is the source of the nutrients for all plants. But Agrochemicals pose serious threats like pollution of soil and cause sterility of soil. So ecofriendly ways can be adopted to complement the action of the agro-chemicals and to decrease their use. One of the best ecofriendly practices is using Plant Growth Promoting Bacteria (PGPB), which promote plant growth. In the present study, bacteria isolated and purified from virgin forest soil of sivalingapuram (Eastern Ghats region, Ananthagiri Mandal, Visakhapatnam, Andhra Pradesh, India).Based on the morphological characters, further bacteria was screened for biochemical and growth promoting properties such as Catalase, Amylase, Protease, Chitinase, Cellulase , IAA, Phosphate Solubilization and production of siderophore. Among the 36 Isolates (sivalingapuram), two isolates were found to possess high values of phosphate solubilizing and production of siderophore activity. It is concluded that high production of siderophore and phosphate solubilizing was performed by potential isolate SS5-15. Further it was characterized by molecular 16S r RNA gene sequencing and phylogenetic tree construction, the bacteria is identified as Enterobacter aerogenus.
