(NCIM 5533) for plant growth promoting characteristics0 aCharacterization of novel acidic and thermostable phytase secret  cMAR  aArticle No: 1010200 v183 aSuccessful agricultural practices in acidic and arid region soils are still challenging worldwide. We investigated Actinomycete strain obtained from soil, which was found to produce extracellular phytase having the optimum pH, temperature of 2.5 and 70 °C, respectively and Plant growth promoting (PGP) attributes. These abilities of the phytase make it novel as compared to other Streptomyces derived phytases. Strain was also evaluated for physiological traits such as salinity, temperature, and pH followed by morphological and molecular identification. The Streptomyces sp. strain (NCIM 5533) displayed additional PGP traits such as indole-3-acetic acid (IAA), ammonia and phosphate solubilization activity. A significant increment in Tomato plant (Solanum lycopersicum) root, shoot and as well as total height in bioassays at laboratory scale and green house level and its ability to colonize roots substantiated its potency as a true plant growth promoting rhizobacteria (PGPR). To our knowledge this is the first report of Streptomyces sp. having the ability to produce acidic and thermostable phytase as well as PGP traits showing enhanced plant growth could have implications in soils having acidic nature and also in arid region.1 aPuppala, K., R.1 aBhavsar, K.1 aSonalkar, V.1 aKhire, J., M.1 aDharne, M., S.  uhttps://library.ncl.res.in/content/characterization-novel-acidic-and-thermostable-phytase-secreting-streptomyces-sp-ncim-5533
