Thoob plaws Ntau Kev Lag Luam Nrog cov kev cai ib puag ncig nruj thiab nce nqi ntawm cov tshuaj siv tshuaj, kev lag luam xws li papermaking, textiles, thiab kev kho dej khib nyiab tau raug daig hauv ob qhov teeb meem ntawm "kev nyuaj hauv cov qauv kev sib ntsib thiab tsis muaj txiaj ntsig". Raws li "natural ntsuab catalyst", laccase tab tom hais txog cov ntsiab lus mob ntawm qhov chaw thiab tau dhau los ua kev xaiv tseem ceeb rau kev lag luam los txo cov nqi thiab cov pa roj carbon monoxide.
Dab tsi Puas yog Laccase? Yuav ua li cas zoo dua li cov tshuaj chemicals?
Laccase tsis yog ib qho enzyme zoo tib yam, tab sis yog hom tooj liab -muaj polyphenol oxidase. Nws cov txiaj ntsig tseem ceeb sawv hauv qhov sib txawv sib txawv rau cov kev kho tshuaj ib txwm muaj:
Cov yam ntxwv tseem ceeb:Nws tuaj yeem catalyze cov tshuaj tiv thaiv nyob rau hauv qhov kub thiab txias yam tsis tas yuav tsum muaj qhov kub thiab txias. Ntxiv mus, nws muaj peev xwm directionally oxidize refractory tshuaj xws li aromatic tebchaw thiab lignin tsis ua puas lub hom phiaj cov khoom.
vs. Cov neeg ua hauj lwm tshuaj:Kev kho ib txwm siv sodium hypochlorite, sulfuric acid, thiab lwm yam, uas tsim cov dej khib nyiab heev; tom qab laccase catalysis, tsuas yog dej thiab tsis muaj teeb meem me me molecules raug tsim, ncaj qha txo qhov kawg - ntawm - cov nqi kho cov yeeb nkab.
2.Laccase daws cov teeb meem kev lag luam li cas?
Txheeb xyuas Lub Hom Phiaj Substrates: Precisely target phenolic pollutants in wastewater, lignin in papermaking raw material, and chromophores in textile dyes.
Catalysis los ntawm Copper Ion Clusters: Plaub tooj liab ions nyob rau hauv lub enzyme molecule ua raws li active chaw, oxidizing substrates ntawm ib tug -electron hloov thiab converting refractory tshuaj mus rau hauv yooj yim decomposable dawb radicals.
Scenario Verification: Hauv kev lag luam papermaking, hloov tshuaj bleaching nrog laccase tuaj yeem txo kev siv cov tshuaj chlorine -raws li cov neeg ua hauj lwm los ntawm 60% thiab txo cov tshuaj oxygen xav tau (COD) ntawm cov dej khib nyiab los ntawm 45%; nyob rau hauv tawv tanning, siv laccase txo cov chromium ion siv los ntawm 30% thaum ua tiav cov khoom siv tau yooj yim dua.
3.Dab tsi yog Cov Ntawv Thov Kev Lag Luam thiab Yav Tom Ntej ntawm Laccase?
Environmental Protection Field: Kho cov dej khib nyiab los ntawm kev siv tshuaj, luam ntawv thiab dyeing, thiab coking industries, degrading tshuaj lom. Tus nqi kho mob yog 20% qis dua li ntawm activated carbon adsorption.
Papermaking Kev Lag Luam: Siv rau hauv kev siv tshuaj lom neeg pulping thiab tshuaj dawb, txo cov tshuaj siv tshuaj thaum txhim kho cov tawv nqaij dawb.
Kev Lag Luam Textile: Siv rau hauv dye decolorization thiab pob zeb ntxuav ntawm denim, hloov cov poov tshuaj permanganate thiab zam kev puas tsuaj rau ntaub lub zog.
Wuhan Healthdream Biotechnology Co., Ltd. tuaj yeem muab cov kev daws teeb meem laccase customized, los ntawm enzyme kev hloov pauv mus rau daim ntawv thov scenario sim, kom pab cov lag luam hauv kev siv cov txheej txheem ntsuab. Peb zoo siab tos txais koj tuaj yeem tiv tauj peb txhua lub sijhawm rau koj cov kev xav tau.
