中文摘要：

探讨了乳酸菌适酸机制有助于抗酸菌株的筛选、发酵过程中工序的优化以及培养基的优化等，进而大大提升发酵产品品质。对质子泵、产碱、细胞膜变化、大分子保护修复以及耐酸调节在内的适酸性调节机制进行了一一阐述。

英文摘要：

The understanding of acid adaptation mechanisms of LAB will benefit screening the acid-tolerance bacteria, the optimization of procedures in the ferment progress and optimization of culture. This will greatly improve the quality of fermented foods. The acid adaptation mechanisms were discussed, including proton pump, the production of alkali, the changes of membrane, protection or repair of macromolecules and the regulation of acid tolerance.
