Abstract：The methods of repeated freezing and thawing, ultrasonic, microwave, salt, enzymatic and liquid nitrogen grinding on wall-breaking were compared and the trehalose yield and broken walls of time were analyzed in this study. Results showed that the method of microwave was the best way to get the rate of broken yeast cells (49%), the trehalose yield (5.64%) and the time (30min). Through the study of the six wall-breaking methods, we provided experimental basis and technical conditions to further comprehensive exploitation and utilization of waste beer yeast.
