摘要
为挖掘盐渍辣椒中的有益微生物资源,进一步提升盐渍蔬菜的质量监控。以盐渍线椒和盐渍米椒为研究对象,采用454焦磷酸测序技术分析盐渍线椒和盐渍米椒真菌的群落组成及相对丰度,结果表明,盐渍线椒已知分类的真菌可归属到2个门、13个纲、17个目、31个科、45个属、87个种,盐渍米椒已知分类的真菌可归属到1个门、1个纲、2个目、2个科、2个属、1个种。盐渍线椒优势菌门为子囊菌门(73.63%)和担子菌门(23.42%)。盐渍米椒只有1个已知分类真菌门类——子囊菌门(99.96%)。盐渍线椒优势真菌属为毕赤酵母属(25.78%)、链格孢属(21.85%)、汉纳酵母属(10.55%)、假丝酵母属(7.82%)、隐球酵母属(6.92%)、枝孢属(6.27%),盐渍米椒优势真菌只有假丝酵母属(93.49%)。盐渍线椒和盐渍米椒的微生物多样性存在较大差异,盐渍线椒的微生物多样性指数高于盐渍米椒。
In order to excavate the beneficial microorganism resources in salted pepper and further improve the quality control of salted vegetables.The community composition and relative abundance in the salted pepper were explored by 454 pyrosequencing technology.The results showed that fungi with known classification status in salted C.annuum L.var.dactylus M could be assigned to 2 phyla,13 classes,17 orders,31 families,45 genera and 87 species.Fungi with known classification status in salted C.annuum L.var.conoides Irish could be assigned to 1 phyla,1 class,2 orders,2 families,2 genera,and 1 species.The dominant phyla in salted C.annuum L.var.dactylus M were Ascomycota(73.63%)and Basidiomycota(23.42%).Ascomycota(99.96%)was the only phylum with known classification status in salted C.annuum L.var.conoides Irish.The dominant genera in salted C.annuum L.var.dactylus M were Pichia(25.78%),Alternaria(21.85%),Hannaella(10.5%),Candida(7.82%),Cryptococcus(6.92%)and Cladosporium(6.27%).The dominant genera in salted C.annuum L.var.conoides Irish was Candida(93.49%).The microbial diversity of salted line pepper and salted rice pepper was significantly different,and the microbial diversity index of salted line pepper was higher than that of salted rice pepper.
