|acetic fermentation;醋酸发酵;乙酸发酵
醋酸发酵(Acetic Acid Fermentation)是一种特定的微生物发酵过程,指在氧气存在下,乙醇(酒精)被特定的细菌氧化转化为醋酸(乙酸)的生物化学过程。它是生产食用醋(如苹果醋、米醋、葡萄酒醋)的核心工艺,也属于不完全氧化发酵的一种。以下是其详细解释:
核心原理与微生物作用者:
过程特点:
应用与产物:
与酒精发酵的关系: 醋酸发酵通常紧接在酒精发酵之后。酒精发酵(由酵母完成,厌氧过程)将糖类(如葡萄糖、果糖)转化为乙醇和二氧化碳。醋酸发酵则利用这个乙醇作为底物,在好氧条件下将其转化为醋酸。因此,完整的“醋”生产通常包含这两个连续的发酵阶段 。
醋酸发酵是一种由好氧性醋酸菌驱动的生物氧化过程,核心是将乙醇转化为醋酸。它依赖于氧气,主要应用于各种风味醋的生产,并具有食品保藏和调味的价值。该过程是连接糖类(经酒精发酵)与醋酸的关键生物转化步骤。

Acetic Acid Fermentation(醋酸发酵) 是微生物将乙醇氧化为乙酸(醋酸)的生物化学过程,主要应用于食醋生产。以下是详细解释:
定义与核心反应
该过程由醋酸菌(如Acetobacter属)主导,通过氧化乙醇生成乙酸和水,反应式为:
$$text{C}_2text{H}_5text{OH} + text{O}_2 rightarrow text{CH}_3text{COOH} + text{H}_2text{O}$$
此过程需氧气参与,属于好氧发酵。
发酵类型
工艺步骤
食醋生产通常分为两阶段:
应用与产物
该过程是食醋制造的核心环节,发酵液经提纯可得冰醋酸(化工原料)。若发酵控制不当,葡萄酒等饮品可能因氧化产生不愉悦的醋酸味。
关键菌种与条件
主要依赖醋酸菌,其活性受温度、pH值及氧气供应影响。工业中常采用混合菌群以增强发酵效率。
如需进一步了解具体菌种或生产工艺,可参考相关微生物学或食品工程资料。
