style="font-size:16px;">(2)作用于微生物的細(xì)胞原生質(zhì)</span> </p> <p> <span style="font-size:16px;">通過(guò)對(duì)部分遺傳機(jī)制的作用，或干擾細(xì)菌等微生物的正常生長(zhǎng)，甚至令其失活，從而使細(xì)胞凋亡。</span> </p> <p> <span style="font-size:16px;">(3)作用于微生物的酶或功能蛋白</span> </p> <p> <span style="font-size:16px;">通過(guò)與酶的巰基作用，破壞多種含硫蛋白酶的活性，干擾微生物體的正常代謝，從而影響其生長(zhǎng)和繁殖。通常防腐劑用于微生物的呼吸酶系，如乙酰輔酶
