【中文摘要】 篩選菌株的發酵曲線表明,培養48～96小時為其增殖生長期;菌齡試驗表明89小時搖瓶菌種活力優于113和137小時者;發酵罐中試培養中,64小時生物量即達33.7g/ml（鮮重）;醪液作為液體菌種,產量及菇形正常,發菌期縮短1/3且現蕾期較早,從醪液中可提取營養濃縮液及粗多糖粉。濃縮液含氨基酸555.38mg/100ml,多糖6.0mg/ml,可溶性固形物≥13％,急性毒性試驗證明無毒,重金屬含量符合國家標準.

【英文摘要】 The fermentation curve of the selected strain of Flammulina velutipes indicates that the multiplication period is 48-96 hours. The activity of the shake flask spawn of 89 hours is better than that of 113 hours and 137 hours. The biomass is 33. 7g/100ml (fresh weight) at 04 hours in the fermenter. The spawn running time reduces one-third and primordiun formation is earlier than that of the normal cultivation when mash is used as liquid spawn. Concentrated nutrient liquid and coarse polysaccharide meal can be extracted from the mash. And the content of amino acid, polysaccharide and soluble solid is 555.38mg/100ml, 6.0mg/ml and >13% re?p. in the concentrated liquid. The concentrated liquid is proved safe by the acute toxic test and the content of heavy metal is in accord with the national standard.
