从香樟分离得到139株内生细菌,采用对峙生长法评价了内生细菌对常见植物病原真菌辣椒疫霉病原菌(Phytophthora Capsici Leonian)、苹果炭疽病原菌(Colletotrichum gloeosporioides)、棉花枯萎菌(Fusariumoxys-porumvasinfectum)、玉米大斑病菌(Exserohilumturcicum(Pass.)Leonardet Suggs)的体外抑制情况.同时,通过内生细菌在微晶纤维平板上的生长情况,对其利用纤维素能力进行了评价.试验结果表明:内生细菌中有35株至少对一种植物病原菌有抑制作用;对辣椒疫霉病原菌(Phytophthora Capsici Leonian)、玉米大斑病菌(Exserohi-lumturcicum(Pass.)Leonardet Suggs)有较为明显的抑制效果;20株能够利用纤维素生长,而且,XG10同时具备抑菌和纤维素分解能力.
139 strains of endophytic bacteria were isolated from camphor, and the effects of endophytic bacteria on common phytopathogenic fungi Phytophthora capsici Leonian, Colletotrichum gloeosporioides, Fusariumoxysporum vasinfectum ) And Leonardet Suggs (Exserohilumturcicum (Pass)) in vitro.At the same time, the ability of endophytic bacteria to utilize cellulose was evaluated by the growth of microcrystalline cellulose.Experimental results showed that: 35 of the endophytic bacteria had at least one inhibitory effect on one plant pathogen and more obvious inhibitory effect on Phytophthora capsici Leonian and Exserohi-lumturcicum (Leonardet Suggs) 20 strains can use cellulose growth, and, XG10 has both bacteriostatic and cellulolytic ability.
