摘要:

从贵州大学真菌资源研究所一4℃冰箱中分离到一株能产生黑色素的地丝霉G014512菌株,经产孢结构、菌落特征及5.8S-ITS序列研究分析,鉴定为地丝霉属Geomyces的一个新种,贵阳地丝霉Geomyces guiyangensis。该菌株能在0℃生长,最适生长温度范围在15-25℃,生长上限温度为40℃。微生物产生黑色素的应用研究越来越受关注,贵阳地丝霉具有潜在的应用价值。

Abstract:

G0140512 fungus strain was isolated from a 4°C refrigerator in the Institute of Fungus Resources of Guizhou University. Morphological study and phylogenic analysis based on the ITS1-5.8S-ITS2 rDNA sequences have proved that this strain is a new taxon of Geomyces, and it is named as G. guiyangensis. The new species can grow at 0°C, and its optimum and lethal temperatures are 15-25°C and 40°C, respectively. The strain can produce obviously melanin in the media. Recently, melanin from the microorganism has been paid more and more attention. G. guiyangensis might be endowed with potential application value.
