| 摘 要： | 以室温放置直至变质的市售酸奶为样品,从中分离出2株酵母菌和4株霉菌,分别命名为Y1、Y2、M1、M2、M3、M4。酵母菌采用形态学和26SrDNAD1/D2区序列分析鉴定,确定Y1为乳酸克鲁维酵母(Kluyveromyces lactis),Y2为马克思克鲁维酵母(Kluyveromyces marxianus)。霉菌经菌落及菌体形态学鉴定,确定M1、M2、M4为青霉(Penicillum),M3为白地霉(Geotrichum candidum)。

| Abstract: | Two yeast strains(marked Y1,Y2)and 4 molds strains(marked M1,M2,M3,M4)were isolated from spoilage yogurts which were purchased from local market.The yeast strains were identified by observing its morphology and 26S rDNA D1/D2 region sequence analysis,the results showed that Y1 was Kluyveromyces lactis,Y2 was Kluyveromyces marxianus.The molds strains were identified by colony and cell morphology,and M1,M2,M4.were Penicillum,M3 was Geotrichum candidum. |
