Degradation of chlorinated herbicides by klebsiella pneumoniae from rhizosphere of rice

벼의 근권으로부터 분리한 klebsiella pneumoniae에 의한 제초제의 분리

It was observed that the strains of Klebsiella pneumoniae isolated from rhizosphere of rice, capable of utilizing chlorivated hervicides, such as 2, 4-dichlorophenoxyacetate, 2-methyl-4-chlorophenoxyacetate and 3-chlorobenzoate, as sole source of carbon and energy and confirmed that their degrading ability of the herbicides was due to plasmid genes. Characteristics of selected strains such as nitrogenase activity, resistances to antibiotics and heavy metal ion were measured.
