人参（Panax Ginseng C.A. Meyer）以其具有抗癌和其他药理作用的治疗有用的人参糖苷而闻名。但是，其在植物中的水平较低，化学合成的高成本使人参皂苷在商业上不可行。因此，提高人参皂苷产量的策略引起了极大的兴趣。本研究报告说，从人参叶子中分离出八种新型内生细菌，微生物转化的菌株的最高人参苯甲苷浓度被鉴定为Paenibacillus polymyxa。通过叶面施用接种人参植物，并通过灌溉增强了植物的生长参数，发病率降低，人参皂苷（RG（1），RE，RE，RF，RF，RB，RB-1，RG（2），RB-2，RB-2，RB-3和RD）在现场实验实验室中。这些结果表明，从人参分离的多型疟原虫是一种有益的内生细菌，具有生物防治特性，可以提高该药用植物的产量和质量。 （c）2014年作者。欧洲植物化学学会。由Elsevier B.V.出版
Ginseng (Panax ginseng C.A. Meyer) is known for its therapeutically useful ginsenosides that have anticancer and other pharmacological effects. However, its low levels in plants and the high costs of chemical synthesis make ginsenosides commercially non-viable; as such, strategies for increasing ginsenoside yield are of great interest. The present study reports the isolation of eight novel endophytic bacteria from ginseng leaves, the highest ginsenoside concentration of microbial transformed strain was identified as Paenibacillus polymyxa. Inoculation of ginseng plants with P. polymyxa by foliar application combined with irrigation enhanced plant growth parameters, reduced morbidity, and increased plant concentration of the ginsenosides (Rg(1), Re, Rf, Rb-1, Rg(2), Rb-2, Rb-3, and Rd) in field experiments. These results indicate that P. polymyxa isolated from ginseng is a beneficial endophytic bacterium with biocontrol properties that can enhance the yield and quality of this medicinal plant.
