Kutsuka enzyme

Pakutsuka kwa ma enzyme, ma cellulase amagwira ntchito pa cellulose yowonekera pa ulusi wa thonje, kumasula utoto wa indigo pansalu. Zotsatira zomwe zimapezedwa ndi kutsuka kwa ma enzyme zitha kusinthidwa pogwiritsa ntchito cellulase ya pH yopanda ndale kapena acidic komanso poyambitsa chipwirikiti chowonjezera pogwiritsa ntchito mipira yachitsulo.

Poyerekeza ndi njira zina, Ubwino wa kutsuka kwa enzyme umawoneka wokhazikika kuposa kutsuka kwa miyala kapena kutsuka kwa asidi chifukwa ndi madzi abwino. Zidutswa zotsalira za pumice zotsuka mwala zimafuna madzi ambiri kuti achotsedwe, ndipo kutsuka kwa asidi kumaphatikizapo kuchapa kangapo kuti apange zotsatira zomwe mukufuna.[5] Kukhazikika kwa gawo lapansi la michere kumapangitsanso njirayo kukhala yoyenga kwambiri kuposa njira zina zopangira ma denim.

Ilinso ndi Zoyipa, Pakutsuka kwa ma enzyme, utoto wotulutsidwa ndi enzymatic umakonda kuyikanso pansalu ("kudetsa kumbuyo"). Akatswiri ochapira Arianna Bolzoni ndi Troy Strebe adadzudzula mtundu wa denim wotsukidwa ndi ma enzyme poyerekeza ndi denim yotsukidwa ndi miyala koma amavomereza kuti kusiyana sikungazindikirike ndi ogula wamba.

Ndipo za Mbiri Yakale, chapakati pa zaka za m'ma 1980, kuzindikira kukhudzidwa kwa chilengedwe ndi kutsuka miyala ndi kuwonjezereka kwa malamulo a chilengedwe kunachititsa kuti pakhale njira ina yokhazikika. Kutsuka kwa ma enzyme kudayambika ku Europe mu 1989 ndipo kudalandiridwa ku United States chaka chotsatira. Njirayi yakhala phunziro la kafukufuku wasayansi kwambiri kuyambira kumapeto kwa zaka za m'ma 1990. Mu 2017, Novozymes adapanga njira yopopera ma enzyme mwachindunji pa denim mu makina ochapira otsekedwa m'malo mowonjezera ma enzyme pamakina ochapira otseguka, ndikuchepetsanso madzi ofunikira kutsuka kwa enzyme.
