Characterization of plant growth promoting rhizobacteria of maize

Isolation and characterization of rhizobacteria are an effort to determine the ability of root colony bacteria to produce various compounds that can be used for various purposes of bio-fertilizer formulations and microbial-based industrial interests. This study aims to characterize biochemically, morphologically and physiologically as well as the ability of root bacteria in maize to produce hormones that can stimulate plant growth. There is a wide variety of isolates morphologically and biochemically, besides that there is the ability of bacterial isolates to physiologically dissolve phosphate, fix nitrogen, produce ACC-deaminase, IAA and GA enzymes.
