Characterization of ACC deaminase producing B. cepacia, C. feurendii and S. marcescens for plant growth promoting activity

Finding solutions to global issues like food security entails greater use of chemicals fertilizers, pesticides, fungicides etc. posing serious risks of soil salinity, heavy metal bioaccumulation. PGPR produce enzyme ACC deaminase which degrades (ACC) 1- aminocyclopropane-1-carobylic acid the immediate precursor of the plant growth hormone ethylene, into α-ketobutyrate and ammonia, thus lowering the level of ethylene in a developing or stressed plant. In the present study, three rhizobacterial strains were isolated from rhizospheric soil of mustard plant in Allahabad region.
