Effect of Different pH Processes on Branched β-1,3-Glucan Production from Submerged Culture of Ganoderma lucidum

영지 (G. lucidum)의 액체배양에 의한 β-1,3-Glucan 생산에 미치는 서로 다른 pH Process의 영향

A submerged cultivation of Ganoderma lucidum was carried out in an air-lift fermenter system, and the effects of different pH processes on extracellular branched ${\beta}$-1,3-glucan(EPS) production and mycelial growth(MDW) were investigated. The controlled pH process improved the production of branched ${\beta}$-1,3-glucan and biomass in comparison to the uncontrolled pH process. However, the maximum production of branched ${\beta}$-1,3-glucan were obtained by the bi-staged pH process. From these results, we confirmed that the bi-staged pH process was the most effective for improving the production of branched ${\beta}$-1,3-glucan from submerged culture of G. lucidum.
