摘要: A novel enhanced triterpenes fermentation production process by Ganoderma lucidum G0119 with the addition of oleic acid in the medium has been developed and optimized. All of the six exogenous additives tested were found to exhibit stimulatory effect on mycelial growth and triterpenes biosynthesis by G. lucidum. The results show that oleic acid addition had significant role in promoting triterpenes production. The optimal concentration and time of oleic acid addition were determined to be 30 mL/L and 0 h, respectively. Furthermore, three significant factors influencing triterpenes production were identified as glucose, magnesium sulfate and temperature using the Plackett-Burman design. The optimized conditions by central composite design were 27.83 g/L glucose, 1.32 g/L magnesium sulfate, 26.2 degrees C temperature. The triterpenes fermentation yield with the optimized medium based on actual confirmatory experimental data in 6 L fermentor was 1.076 g/L versus the statistical model predicted value of 1.080 g/L. Our innovatively developed triterpenes fermentation production technology and process has been proven to produce high triterpenes productivity and yield conceivably useful for industrial production.
