The Screening and Identification of Endophytic Bacteria of Amorphophallus konjac against Erwinia carotovora var. carotovora

In this study, 127 endophytic bacteria of konjac were isolated by similar habitat separation method. Three strains (M3, M2, 1-7) were screened out for control the soft rot of Amorphophallus konjac by plate screening test and greenhouse rescreening test. The bacteria strains M3, M2, 1-7 were identified as Bacilus subtilis, Bacillus amyloliquefaciens and Pantoea agglomerans respectively, according to the characters of cultural colonies, morphological observation, biochemical and physiological identification (Biolog carbon source utilization analysis), 16S rDNA sequences analysis. This is the first report of use host plant endophytic bacteria as biocontrol agents to control the disease.
