Ensifer sp. CNN3 - AN INDIGENOUS BACTERIAL STRAIN WITH PLANT GROWTH PROMOTING AND ORGANOPHOSPHORUS DEGRADING PROPERTIES IN VIETNAM

An indigenous effective bacterial strain has been isolated from soil samples of contaminated tea farming site in Northern Vietnam with chlorpyrifos degradability and plant growth promoting characteristics. The bacterial isolate was determined to belong to genus Ensifer (syn. Sinorhizobium), and its degrading property for OPP substrate chlorpyrifos in culture as well as in test soil were studied. The results open a prospect of applying the dual-effective bacterial strain in agriculture practices either to reduce the use of chemical fertilizer or to remediate OPP contaminated planting soils.
