【中文摘要】 研究表明 ,液體培養條件下 ,茯苓經 0～ 4 8h的適應期 ,4 8～ 14 4h的增殖期后進入穩定期 ,發酵液 pH驟降。經檢測 ,發酵液中含有包括十六烷酸和十八烷酸在內的有機酸 ;發酵罐培養 12 0h ,生物量≥ 30g/10 0mL(鮮重 )。茯苓營養濃縮液多糖含量≥ 5 .0mg/mL ,氨基酸含量≥4 80mg/10 0mL。動物實驗證明 ,茯苓營養濃縮液具有顯著的抗疲勞和提高機體免疫力作用 ,其重金屬和微生物指標均符合國家標準。

【英文摘要】 Studies on the submerged culture of Poria cocos showed that followed by 0～48h adaptation period and 48～144h multiplication period, there was the stable growth period with a sudden reduction of pH in the fermentation liquid. The experimental results showed that there were organic acids such as hexadecanoic acid and octadecanoic acid in the fermentation liquid, and that the biomass content was ≥30g/100mL(fresh weight) after 120h fermentation. While the polysaccharide content was ≥5.0mg/100mL and the amino acid content was ≥480mg/100mL in the extracted concentrated nutrient solution of Poria cocos. And the results of the animal tests showed that the effect of concentrated nutrient solution of Poria cocos on the increment of organism immunity and fatigue resistance ability was extremely significant, and the contents of heavy metal and micro organism index accorded with the national standard.
