Abstract
ACC deaminase regulates the production of ethylene level of plants by metabolizing 1-aminocyclopropane-1-carboxylate (ACC) into α-ketobutyric acid and ammonia. It was observed that two important phyllospheric bacteria of Spinach (Spinacia oleracea) which are Paenibacillus polymyxa SNKp6 and Bacillus thuringiensisSNKr10 exhibit significant ACC deaminase activity which can help plant growth under stressful conditions like heavy metal contaminated sites. This growth activity was studied by in vitro seed germination of Vigna radiata plant. In the present study, we concluded that these two important bacterial strains can be helpful for plants to grow under stressful conditions and also help in their growth.
