摘要:
为了探究艾比湖湿地可培养黏细菌多样性及该地区黏细菌菌株对病原微生物的拮抗作用。通过传统的黏细菌分离方法对采自艾比湖湿地15份样品中的黏细菌进行分离,结合形态学观察、生理生化特征和16S rDNA序列分析,确定菌株的分类地位,并通过平板对峙法分析其抗菌活性。试验结果表明,从采集的15份样品中共分离纯化出22株疑似菌株,经鉴定将其归类为黏球菌属,其中6株为橙色黏球菌(Myxococcus fulvus),14株为变绿黏球菌(M. virescens),2株只鉴定到属(Myxococcus sp.)。抗菌活性分析显示,22株黏细菌表现出不同的抗菌活性,其中14株可以抑制金黄色葡萄球菌(Staphylococcus aureus)的生长,14株黏细菌均可抑制沙门氏菌(Salmonella typhimurium)和大肠杆菌(Escherichia coli)的生长,15株对枯草芽孢杆菌(Bacillus subtilis)的生长表现出抑制作用,17株可以抑制酿酒酵母菌(Saccharomyces cerevisiae)的生长,11株能够抑制链格孢菌(Alternaria alternata)的生长。艾比湖湿地可培养黏细菌多样性不高,且黏球菌属为该地区可培养黏细菌的优势种属。初步筛选出的2株黏细菌菌株WCX_LG-5和TF_YJC-1,具有广谱的抗菌活性,是一类极具开发潜力的微生物资源。
