| 摘 要： | 本文研究了MgSO4、KH2PO4二种元机物与香菇Cr-02液体发酵生长量的关系。结果证明：在27℃摇床转速为134r/min的培养条件下，MgSO4浓度0.05%，KH2PO4浓度为0.10%，发酵96h香菇生长量最大，发酵液透光率T在630nm波长时达135.8%，其湿菌体产量32.6g/100mL，发酵液由深褐色变成黄色、粘度大、透明，菌丝体个体较大且数目较多。

| Abstract: | In this paper we study the relationship between MgSO4,KH2P O4 and biomass of shiitake.The results reveal that the biomass of shiitake is the largest after fermented for 96h on condition that the temperature is at 27℃ ,the shaker rotation speed is at 134 r/mim,the concentration of MgSO4 is 0.05 %,that of KH2PO4 is 0.01%.The transmittance of the fermentation solution is 135.8%.When the wavelengh is 630nm and the yield of wet somatic is 32.6g/100m L,the fermentation solution turns light yellow,which is transparent,the body of myc elium pellet is a bit large and the number of mycelium pellet is a bit large too . |
