ABSTRACT
In this study, traditional plate culturing method was used to isolate autotoxin-degrading microbial strains, and which were then identified by 16S rDNA homological analysis and morphological characteristics. Furthermore, the growth and autotoxin-degrading efficiency of them were analyzed by liquid culturing method and GC-MS to illustrate their autotoxin-degradation characteristics. As a result, five bacterial strains having autotoxin-degrading activity were isolated from 6-years ginseng nonrhizospheric soil successfully, and which can growth successfully by taking autotoxins added artificially as carbon source in liquid culturing condition. Results indicated that it was feasible to isolate autotoxin-degrading bacteria from ginseng nonrhizospheric soil, and the isolated bacterial strains can be used to degrade autotoxins in soils once planted Panax ginseng.
