Abstract: Improvement of microbial strains for the production of industrial products has been a hallmark of all commercial, microbial fermentation processes. The present investigation deals with the isolation and characterization of bacteria for the enhancement of seed germination. Five isolate were selected by screening test. Based on morphologically, and biochemical characterization the isolates were identified as Pseudomonas sp, Bacillus sp, E.coli sp, Proteus sp, Shigella sp. The isolated bacterial strains were subjected to mutation process for strain improvement by sequential treatment with physical agents (UV) and chemical agents (EMS). Further, strain improved isolates were tested for the enhancement of seed germination in rhizosphere soil.
