摘要
研究灵芝菌丝体发酵中碳源、氮源、pH和时间对菌丝干重的影响来优化灵芝菌丝体的发酵条件。结果表明,培养条件中对灵芝菌丝体生长影响的顺序为:氮源>碳源>时间>pH。通过L9(34)正交优化试验确定的灵芝菌丝体液体最佳发酵条件为:玉米粉2%,菜籽饼粉0.4%,培养时间7 d,pH值7.0。本研究结果为灵芝菌丝体发酵工业化生产提供了理论参考和试验依据。
This study aimed to optimize the fermentation condition of Ganoderma lucidum mycelium by studying the effects of carbon sources, nitrogen sources, pH and incubation time on the dry weight of mycelium in G. lucidum fermentation. Results showed that the descending order of the influences on G. lucidum mycelium growth was nitrogen sources〉carbon sources〉incubation time〉pH. Based on L9（34） orthogonal experiments, the optimal fermentation condition of G. lucidum mycelium was determined as： fermentation medium of 2% corn powder, 0.4% rape seed cake powder, incubation time of 7 d and pH of 7.0. This study provides theoretical reference and experimental basis for the development and utilization of G. lucidum mycelium fermentation industrial production.
