摘　　要：利用涂布法、划线法等技术手段,从洋河成品大曲中分离得到1株代谢产生核苷类健康功能因子的丝状真菌。利用形态观察和分子生物学相结合的技术手段,将核苷代谢功能菌鉴定为横梗霉。高效液相分析表明,该菌可代谢产生具有重要生理活性的次级代谢产物——腺苷和尿苷。该研究为核苷健康功能菌在中国白酒酿造中的应用奠定了基础。A nucleoside-producing fungus strain was isolated from Yanghe Daqu by using spread plate and streaking. On the basis of morphological and molecular analysis, it was identified as Lichtheimia ramosa. HPLC analysis showed that Lichtheimia ramosa could produce adenosine and uridine with diverse bioactivities. This study laid the foundation for the application of nucleoside-pro- ducing fungus in Baijiu production.
