摘要
研究了猴头菇(Hericium erinaceus)液体菌种培养基最佳生产配方和液体发酵条件。结果表明:在所设定的5组培养基中,最优的一组培养基配方为葡萄糖3%,可溶性淀粉2%,酵母膏1%,KH2PO40.1%,MgSO4.7H2O 0.06%。在此培养基的基础上做单因素实验得出最佳pH为5.5;最佳温度为27℃;最佳转速为180 r.min-1;最佳装液量为120 mL.(250 mL)-1。由此得到的菌丝球生物量在同一因素的几个实验组内较好。
Selection of Hericium （Hericium erinaceus）Strain liquid medium and exploration of fermentation condition were studied. The results showed that the best suitable medium among five tested medium was glucose 3 %, soluble starch 2 %, yeast extract 1 %, K H2 PO4 0.10%, MgSO4 · 7 H2 O 0.06 %. According to the single factor experiment,for getting best biomass, the optimal p H was 5.5 % the optimal temperature was 27℃ ;optimal rotate speed was 180 r · min^-1 ;optimal liquid volume was 120 mL per 250mL.
