摘  要:
灰树花是药食两用真菌,富含多糖、氨基酸和矿物元素,可用液体深层发酵大规模生产。本试验研究分析了文献报导的营养因子对灰树花发酵的影响,并选择得到各因子及水平。以菌丝干重作为试验指标,通过四因素四水平的正交试验得到了优化培养基的组成为:马铃薯250g/葡萄糖30g,麸皮20~35g,酵母膏1.0~2.5g,磷酸二氢钾取2~5g,硫酸镁取0.5~2g,水1L,菌丝生物量干重为19.7g/L。方差分析表明混合碳源的浓度比对试验指标有显著影响。与文献结论进行了对比,得到不同结论。

摘  要:
Containing rich polysaccharides ,amino acids and mineral elements,Grifola frondosa which may be produced by submerged fermentati on in larger scale was edible -medicinal fungi.By analyzing effects on submerged fermentation of nutrit ion factors ,factors and levels were obtained.When the weight of dry fungi was used as the target,by orthogonal test which contained 4factors and 4levels,the optimum component of medium of Grifola frondosa was as follows:potato 250g,glucose30g ,yeast cream 1.0~2.5g,KH 2 PO 4 2~5g,MgSO 4 0.5~2g,water 1L.The optimum weight of dry fungi was 19.7g /L.The effect on target of the mass concentration r atio of carbon source was prominent.The test results were different when compared with those results in o ther articles.
