Abstrakt: Ethylene is Produced in high quantities in saline stress conditions, which lowers plant growth and productivity. Bacteria that stimulate plant growth isolated from soils can improve plant growth and productivity under stresses conditions. In this study, 15 halo bacterial isolates were isolated, 5 of which were produced 1-aminocyclopropane-1- carboxylic acid (ACC) deaminase and auxin. Under the toxic concentration(75mM) for mung bean cuttings 10- old- day (as an experimental system). Bacteria grown on OF salts minimal medium + Hoagland solution with half strength, its able to remove toxicity completely when exogenous after exposure to toxicity by raising cuttings rooting response and reducing the activity of both indole acetic acid oxidase (IAAO) and Lipoxygenase (LOX) enzymes, So the statistical differences between toxicity treatment, control disappeared and cuttings were response as unstressful.
