Hauv cov txheej txheem ntxuav enzyme, cellulases ua rau nthuav tawm cellulose ntawm cov paj rwb fibers, tso cov xim indigo los ntawm cov ntaub. Cov nyhuv ua tiav los ntawm kev ntxuav cov enzyme tuaj yeem hloov kho los ntawm kev siv cellulase ntawm nruab nrab lossis acidic pH thiab los ntawm kev qhia ntxiv kev ntxhov siab los ntawm kev siv xws li cov pob steel.
Kev sib piv rau lwm cov tswv yim, Qhov Zoo ntawm Kev Ntxuav Enzyme yog suav tias yog kev ruaj ntseg dua li kev ntxuav pob zeb los yog kua qaub ntxuav vim nws muaj dej ntau dua. Cov pumice seem ntawm cov pob zeb ntxuav xav tau ntau cov dej kom tshem tawm, thiab kev ntxuav cov kua qaub yuav tsum muaj ntau lub voj voog ntxuav kom tsim tau cov nyhuv xav tau.[5] Lub substrate-specificity ntawm enzymes kuj ua rau cov txheej txheem ntau refined dua lwm txoj kev ua denim.
Nws kuj muaj qhov tsis zoo, Hauv kev ntxuav enzyme, zas xim tso tawm los ntawm kev ua haujlwm enzymatic muaj lub siab xav rov qab los ntawm cov ntaub ntawv ("rov qab staining"). Cov kws tshaj lij ntxuav Arianna Bolzoni thiab Troy Strebe tau thuam qhov zoo ntawm enzyme-ntxuav denim piv rau cov pob zeb ntxuav denim tab sis pom zoo tias qhov sib txawv yuav tsis pom los ntawm cov neeg siv khoom nruab nrab.
Thiab hais txog Keeb Kwm, Nyob rau nruab nrab-1980s, kev lees paub ntawm ib puag ncig cuam tshuam ntawm kev ntxuav pob zeb thiab ua kom cov kev cai ib puag ncig ua rau muaj kev xav tau rau lwm txoj hauv kev. Enzyme ntxuav tau qhia hauv Tebchaws Europe hauv xyoo 1989 thiab tau txais yuav hauv Tebchaws Meskas rau xyoo tom ntej. Cov txheej txheem tau ua ib qho kev kawm ntawm kev tshawb fawb hnyav dua txij li xyoo 1990s lig. Hauv xyoo 2017, Novozymes tau tsim cov txheej txheem los txau cov enzymes ncaj qha rau ntawm denim hauv lub tshuab ntxhua khaub ncaws kaw uas tsis yog ntxiv cov enzymes rau lub tshuab ntxhua khaub ncaws qhib, txo cov dej uas xav tau rau cov enzyme ntxuav.
