牛肝菌生长与发酵主要影响因子的鉴别

Determination of the Most Important Factors Affecting the Mycelium Biomass and Exopolysaccharide Yield in Submerged Fermentation

摘要:

采用Plackett-Burman设计法,分别研究了影响牛肝菌(Boletussp.)ACCC50328菌丝生长和发酵产糖的21个相关因素.结果表明,影响牛肝菌ACCC50328菌株菌丝生长速度的主要因子为葡萄糖、麦芽糖、酵母膏、KH2PO4、(NH4)2SO4、FeSO4、发酵温度、发酵时间及装液量;影响该菌株胞外多糖含量的主要因子为麦芽糖、酵母膏、(NH4)2SO4、CuSO4·5H2O、FeSO4和发酵时间.

Abstract:

Mycelium biomass and polysaccharide accumulation in submerged fermentation by Boletus sp. ACCC 50328 are strongly influenced by many internal and external factors, namely medium constituents and fermentation conditions. the Plackett-Burman technique was a
