中文摘要 | 經修正過之模式已經實驗證明可適用於pH有控制及pH無控制之兩種乳酸發酵情 形。此結果證明了乳酸發酵生產乳酸之反應速率只單獨與乳酸菌之生長有關,而事實上與 生長無關之機制並不顯著。 本研究證明了乳酸之非競爭性抑制乃是由總乳酸(包括乳酸鹽)量所引起,而非僅由 非解離型之乳酸所造成。 |
英文摘要 | Kinetic model analysis of the lactic acid production by Lactobacillus helviticus from lactose has confirmed the invalidity of Leudeking's model. This innovative model is proved to be valid for both pH- controlled and pH-uncontrolled lactic acid fermentations; i.e., the lactic acid production rate is uniquely growth-associated, while the non-growth mechanism is insignificant. This article also shows that non-competitive inhibition is caused by the total concentration of all the lactate species rather than by the undissociated form. |
