%X A large number of different microorganisms are commonly found in the soil including bacteria, fungi, actinomycetes, protozoa and algae of these bacteria are by far the most common type of soil microorganism possibly because they can grow rapidly and have the ability to utilize a wide range of substances as either carbon or nitrogen sources. Use of naturally occurring, free living bacterial species, which can protect and promote plant growth by colonizing and multiplying along the surface of the root and/or root cortex. In our present investigation was to study the plant growth promoting (PGP) activities and chromium reducing Bacillus sp. from rice fields of in and around Erode district. From 25 soil samples 63 different Bacllius sp. were isolated. Among the 63, eight Bacillus sp. (BA1 to BA 8) possess effective PGP activities. In eight different Bacillus isolates particularly (BA1, BA3, BA4 and BA6) exhibited maximum plant growth promoting and chromium reducing activities. In addition to these traits, plant growth promoting bacterial isolates must be rhizospheric competent, able to survive and colonize in the rhizospheric soil.
