| 摘 要： | 采用26S rRNA基因D1/D2区系统发育分析的方法对CICC(中国工业微生物菌种保藏管理中心)保藏的15株白地霉(Geotrichum candidum)菌种进行复核鉴定。系统发育分析结果表明15株白地霉属于地霉属的成员,且形成两个系统发育分支,系统发育上最接近Galactomyces geotrichum NRRLY-17569T,与其同源性为96.3%～98.3%。15株白地霉26S rRNA基因D1/D2区序列显著不同于地霉属的模式种及其它种,可能代表地霉属的两个新种,但这一结论尚需进一步的实验去证实。

| Abstract: | The 26S rRNA gene D1/D2 domain sequences of 15 strains originally identified as Galactomyces geotrichum from the Chinese Industry Culture Collection (CICC) were determined. The results indicated that these strains differed from the type strain of Galactomyces geotrichum and other species of the genus remarkably. Two groups were recognized from the 15 strains which possibly represent 2 novel species of Galactomyces. Further molecular study is needed to confirm their taxonomic status. |
