摘要:
从药用植物怀地黄的根中分离出32株内生细菌,并选择大肠杆菌、金黄色葡萄球菌、黑曲霉、地黄斑枯病和地黄根腐病5种菌作为供试菌株,采用点菌法、平板对峙法和菌饼法测定抗菌活性。结果显示,怀地黄中分离的32株内生菌对5种供试菌具有不同的抑制能力,其中有8株细菌对供试的大肠杆菌、金黄色葡萄球菌和黑曲霉都有抑制作用,显示出广谱的抗菌性;有2株细菌DH-10和DH-11对选取的5种供试菌都有抑制作用,且抗菌活性较强,具有生防菌开发潜力。所分离的活性内生菌通过16S rRNA基因序列分析,主要分布在芽孢杆菌属、假单胞菌属和大肠埃希氏菌属,其中对地黄斑枯病和根腐病都具有拮抗作用的内生菌主要集中在芽孢杆菌属中。
