ABSTRACT
Objective To testify the screening function of stachyose on soil bacteria by investigating the bacterial culture in ammonium stachyose medium. Methods The turbidimetry was used to determine the absorbance of microbial suspension at 600 nm per 2 h under the same initial concentration of the microbial suspension and to draw their growth curves. Results Most of soil bacteria utilized stachyose ineffectively, while only a few of them grown well in ammonium stachyose medium. Conclusion Since the major soil bacteria can not take stachyose fully as their energy resources, the species and quantity of rhizobacteria may decrease largely and only a few that utilized stachyose better can develop vigorously. Those rhizobateria with better utilization of stachyose may multiply so rapidly as potential ones in the rhizosphere of Rehmannia glutinosa that the disequilibrium of soil microorganism appears.
