| 摘 要： | 鞘氨醇单胞菌CJ-5菌株在以几丁质为碳源的培养基上生长,既产生几丁质酶又产生壳聚糖酶.利用其发酵液进行抑制真菌,促进植物生长等生物活性的研究及作用机理的探讨,发现CJ-5菌株的几丁质发酵液具有抑制番茄枯萎病菌,促进水稻扩叶生根的效果,显示了潜在的防治植物病原菌及促进植物生长的能力.

| Abstract: | Sphingomonas sp. CJ-5 strain produces both sponse to chitin induction. The physiological function of chitinase and chitosanase into CJ-5 fermented broth was also surrounding medium in retested. The fermentor fuild showed antifungal activity against Fusarium oxysporum f.sp, lycopersici and growth-stimulation of Oryza sativa seedings to a certain extent. These results revealed a potential role for chitinase in biological control of plant pathogenic fungi and chitin oligosaccharide in stimulation growing of plant. |
