研究表明 ,作为液体菌种应用时 ,榆黄蘑发酵培养的适宜碳源为葡萄糖和玉米粉 ,适宜氮源为酵母膏和豆饼粉 ,最适培养温度 2 5℃ ,4 8h前为其适应期 ,4 8～ 96h为增殖生长期 ,其后生物量既可达 30g·10 0mL-1(鲜重 ) ,经检验合格的醪液便可作为液体菌种利用 ,较传统固体种定植早 ,萌发点多 ,发菌速度快 The results showed that the optimal carbon source for the fermentation of the yellow-fungi was glucose and corn flour, and the suitable nitrogen source was yeast extract and bean cake flour. The optimum culture temperature was 25 ℃, , 48 ~ 96h for the proliferative growth phase, after which the biomass can reach 30g · 10 0mL-1 (fresh weight), the qualified mash can be used as liquid bacteria, compared with the traditional solid species of early planting, germination More points, germination speed
