用氦氖激光对甘蔗糖蜜酒精工业性生产用酿酒酵母菌ＳａｃｈａｒｏｍｙｃｅｓｃｅｒｅｖｉｓｉａｅＡＳ２１１８９进行了辐照，发现细胞分裂受到了抑制从不同组别中选择了１３４株被照射过的酵母菌进行观测，发现有九株的产酒精率比未经激光照射的酵母菌较高或较低本文还讨论了氦氖激光对酵母菌的刺激机理，并用统计学方法研究了激光刺激的平均效应 Irradiation of Saccharomyces cerevisiae AS21189 on Saccharomyces cerevisiae AS21189 for industrial production of sugarcane molasses was carried out by using He-Ne laser and found that cell division was inhibited. From the different groups, 134 irradiated yeasts were selected for observation. Nine strains were found to have a higher or lower alcohol production rate than those without laser irradiation. The mechanism of He-Ne laser irradiation on Saccharomyces was also discussed and the average effect of laser stimulation was studied statistically
