Abstract

Sugar molasses was used to culture the High nuclear Saccharomyces.The fermentation condition was studied.The optimum medium ingredients and culture condition were obtained as followed:the initial pH 5.0,the complex nitrogen sources of yeast powder and urea;by increasing the rate of the hydrolyzation of the sucrose,the logarithm period of NY-1 is prolonged and the cell density was also increased.The cell dry weight was up to 15.4g/L when the yeast was cultured in baffled flasks.

Key words： high nuclear Saccharomyces; RNA; sucrose; sugar molasses
