Ua ntej tshaj plaws, fermentation yog ib yam ntawm cov txheej txheem lom neeg, uas yog cov txheej txheem lom neeg ntawm kev hloov cov suab thaj rau hauv carbon dioxide thiab cawv nyob rau hauv cov xwm txheej anaerobic. Hauv cov txheej txheem no, cov piam thaj yog anaerobically decomposed rau hauv ethanol thiab carbon dioxide, thiab ces cov ethanol yog ntxiv decomposed rau hauv acetic acid thiab carbon dioxide.

Isopropanolyog ib hom cawv, uas yog cov kua dej tsis muaj zog thiab cov nplaim taws. Nws yog feem ntau siv los ua ib qho hnyav thiab antifreeze. Nyob rau hauv tus txheej txheem ntawm fermentation, qab zib yog anaerobically decomposed rau hauv ethanol thiab carbon dioxide, thiaj li hais tias isopropanol yog tsim. Yog li, nws tuaj yeem hais tias isopropanol yog cov khoom ntawm fermentation.

Txawm li cas los xij, cov txheej txheem ntawm fermentation yog qhov nyuaj heev, thiab cov xwm txheej thiab cov ntaub ntawv xav tau rau fermentation txawv. Tsis tas li ntawd, cov khoom ntawm fermentation kuj yuav txawv. Yog li, cov xwm txheej tshwj xeeb thiab cov ntaub ntawv xav tau rau kev tsim cov isopropanol tsis meej.

Feem ntau, isopropanol yog ib yam khoom ntawm fermentation. Txawm li cas los xij, cov xwm txheej tshwj xeeb thiab cov ntaub ntawv xav tau rau nws qhov kev tsim khoom tsis meej. Nws yog ib qho tsim nyog yuav tsum tau kawm ntxiv txog cov txheej txheem ntawm fermentation thiab cov xwm txheej thiab cov ntaub ntawv xav tau rau nws cov khoom tsim kom tau txais cov ntaub ntawv raug ntau ntxiv txog kev tsim cov isopropanol.
