Abstract:
The Ganderma lucidum was used as experimental material,the effects of different heat stress temperature,heat stress starting time and heat stress duration time on the synthesis of ganoderic acid were studied by single factor and orthogonal experimental methods,and the content of ganoderic acid through the optimization of heat shock conditions was improved,in order to provide some ideas and theoretical reference value for the efficient production of ganoderic acid.The results showed that the biosynthesis of ganoderic acid was affected by the different temperature,starting time and duration time of heat stress.Then the optimal conditions for the production of ganoderic acid were as follows,the heat stress temperature was 42 ℃,the starting time was 7th day and the duration time was 6 hours,which measured by the orthogonal experiment.Under this condition,the content of ganoderic acid was as high as 88.23 mg·L-1,which was 1.93 times higher than the control that without heating stress treatment.This study confirmed that the content of ganoderic acid can be improved through the optimization of heat stress conditions in liquid fermentation of Ganderma lucidum.
