Brewer's yeast has been widely used in the food industry, and the autolysates thereof are increasingly being studied for their valuable nutritional compositions. Yeast autolysis is most affected by medium composition and temperature. In this study, a thermosensitive autolytic brewer's yeast P-510 was obtained with atmospheric and room temperature plasma mutagenesis plus 5-bromo-chloro-3-indolyl phosphate screening. The mutant rapidly autolyzed at 37 °C and the autolysates contained more active components and showed higher antioxidant activities compared with that of the parental strain, which indicated that the mutant's autolysates can potentially be used as functional food and nutritional ingredients. Transcriptomic analysis of the mutant and parental strains at 28 and 37 °C suggested that thermosensitive autolysis of P-510 was probably caused by mitochondrial disfunction, glycogen metabolic flux of glycolysis and pentose phosphate pathway disorder, as well as hexose transport inhibition. The results revealed the important role of mitochondrial metabolism and glycogen utilization regulation in heat stress response of yeast.
