| 摘 要： | 从乐山市售生姜根状茎中分离纯化内生细菌,并以金黄色葡萄球菌（Staphyloccocus aureus）、大肠杆菌（Escherichia coli（E.coli））、枯草芽孢杆菌（Bacillus subtilis）、耐甲氧西林金黄色葡萄球菌（Methicillin-resistant staphylococcus aureus,MRSA）为靶标菌进行抑菌试验。研究结果表明：生姜中存在大量的内生细菌,分离获得的9个菌株对四种靶标菌都有不同程度的抑菌作用,2个菌株（SJ1 and SJ9）抑菌效果非常显著,相对抑菌率超过170%。

| Abstract: | Endophytic bacteria were separated and purificated from commercially available ginger rhizome in Leshan city. Antagonistic strains against to Staphylococcus aureus,Escherichia coli,Bacillus subtilis,methiciHin-resistant Staphylococcus aureus （MRSA） were screened. The results showed that there were a lot of endophytic bacteria isolated from ginger.Nine strains isolated from ginger have varying degrees of inhibitory effect on the four target bacteria,inhibitory effect of two strains（SJ1 and sJg）wss very significant, the relative inhibitory rate of over 170%. |
