【中文摘要】 探索樹舌發酵產生高活性的碳酸酐酶抑制劑的營養需求。試驗以抑制碳酸酐酶活性為指標,通過單因素試驗篩選出適宜碳源、氮源及復合營養因子,通過正交試驗進一步觀察了各組分之間的相互作用。試驗結果表明,樹舌發酵合成碳酸酐酶抑制劑的較為適合的培養基為:果糖20 g.L-1、NaNO3 2 g.L-1、馬鈴薯173 g.L-1、(NH4)2SO4 1.3 g.L-1。使用該培養基其發酵液對碳酸酐酶的抑制率可達91.43%,顯著高于未優化的培養基(69.81%)。

【英文摘要】 In this study,the nutritional needs of Ganoderma applanatum to produce high active carbonic anhydrase inhibitors was investigated.Firstly,optimal carbon and nitrogen sources,and natural components were selected by single factor experi-ments according to carbonic anhydrase inhibition ratio of the fermentation broth.Then,inter-action of these factors was observed by orthogonal testsstyle.Finally,the inhibitory ratio based on basal medium and optimized medium was compared.The opti-mized medium contained: fructose 20 g.L-1,NaNO3 2 g.L-1,potato 175 g.L-1,(NH4)2SO4 1.3 g.L-1,In the medium,the highest inhibition ratio(91.43%) was achieved which was significantly higher than basal medium(69.81%).
