|acetic fermentation;醋酸發酵;乙酸發酵
醋酸發酵(Acetic Acid Fermentation)是一種特定的微生物發酵過程,指在氧氣存在下,乙醇(酒精)被特定的細菌氧化轉化為醋酸(乙酸)的生物化學過程。它是生産食用醋(如蘋果醋、米醋、葡萄酒醋)的核心工藝,也屬于不完全氧化發酵的一種。以下是其詳細解釋:
核心原理與微生物作用者:
過程特點:
應用與産物:
與酒精發酵的關系: 醋酸發酵通常緊接在酒精發酵之後。酒精發酵(由酵母完成,厭氧過程)将糖類(如葡萄糖、果糖)轉化為乙醇和二氧化碳。醋酸發酵則利用這個乙醇作為底物,在好氧條件下将其轉化為醋酸。因此,完整的“醋”生産通常包含這兩個連續的發酵階段 。
醋酸發酵是一種由好氧性醋酸菌驅動的生物氧化過程,核心是将乙醇轉化為醋酸。它依賴于氧氣,主要應用于各種風味醋的生産,并具有食品保藏和調味的價值。該過程是連接糖類(經酒精發酵)與醋酸的關鍵生物轉化步驟。

Acetic Acid Fermentation(醋酸發酵) 是微生物将乙醇氧化為乙酸(醋酸)的生物化學過程,主要應用于食醋生産。以下是詳細解釋:
定義與核心反應
該過程由醋酸菌(如Acetobacter屬)主導,通過氧化乙醇生成乙酸和水,反應式為:
$$text{C}_2text{H}_5text{OH} + text{O}_2 rightarrow text{CH}_3text{COOH} + text{H}_2text{O}$$
此過程需氧氣參與,屬于好氧發酵。
發酵類型
工藝步驟
食醋生産通常分為兩階段:
應用與産物
該過程是食醋制造的核心環節,發酵液經提純可得冰醋酸(化工原料)。若發酵控制不當,葡萄酒等飲品可能因氧化産生不愉悅的醋酸味。
關鍵菌種與條件
主要依賴醋酸菌,其活性受溫度、pH值及氧氣供應影響。工業中常采用混合菌群以增強發酵效率。
如需進一步了解具體菌種或生産工藝,可參考相關微生物學或食品工程資料。
