  4. The paper adopted the common breeding way by series of mutagen treating to the yeast ' s cell and spheroplast. finally, the excellent mutant 75l 3555 was obtained. its nature of the production was determined and it can product ethanol on the condition of 40 and have high fermentative speed and stable production. on the other hand, the test was made that the best fermentative condition was found. in the malt juice, adding 0. 02 % k + or 0. 03 % a13 + can increase the production strikingly and adding some degree concentration trahalose can increase the production too and cut short the time of taming. in the study of using molasses producting ethanol, we can obtain high productivity contained the following composition : nitrogen source 1. 5 % maize and 0. 075 % ( nh4 ) 2so4
