Laccase yog dab tsi?

Laccase yog ib qho polyphenol oxidase uas muaj tooj liab, uas feem ntau muaj nyob rau hauv daim ntawv dimer lossis tetramer. Laccase thawj zaug tau tshawb pom los ntawm tus kws tshawb fawb Nyiv Yoshi hauv cov xim av ntawm tsob ntoo, thiab tom qab ntawd pom muaj nyob rau hauv cov nceb, cov kab mob thiab cov kab kuj muaj laccase. Thaum kawg ntawm lub xyoo pua 19th, GB etranel thawj zaug rho tawm nws ua ib qho khoom siv kho los ntawm cov xim nyoos thiab hu ua laccase. Cov chaw tseem ceeb ntawm laccase hauv xwm yog cov nroj tsuag laccase, tsiaj laccase thiab microbial laccase. Microbial laccase tuaj yeem faib ua cov kab mob laccase thiab fungal laccase. Bacterial laccase feem ntau yog secreted los ntawm lub cell, thaum fungal laccase feem ntau yog faib tawm sab nraud lub cell, uas yog hom kawm ntau tshaj plaws tam sim no. Txawm hais tias cov nroj tsuag laccase ua lub luag haujlwm tseem ceeb hauv cov txheej txheem physiological ntawm lignocellulose synthesis thiab tiv taus kev ntxhov siab biological thiab abiotic, cov qauv thiab mechanism ntawm cov nroj tsuag laccase tsis tau paub.

Daim Ntawv Thov

Laccase tuaj yeem ua rau muaj kev oxidation ntawm ntau tshaj 200 hom tshuaj sib txawv, siv dav hauv cov khoom noj, textile, ntawv thiab lwm yam lag luam. Laccase muaj cov khoom ntawm oxidizing cov tshuaj phenolic, uas tuaj yeem hloov pauv mus ua polyphenol oxides. Polyphenol oxides lawv tus kheej tuaj yeem polymerized los ua cov khoom loj, uas raug tshem tawm los ntawm cov ntaub lim dej. Yog li laccase siv rau hauv kev tsim dej haus rau kev ua kom dej haus ntshiab. Laccase tuaj yeem ua rau cov tshuaj phenolic hauv kua txiv hmab thiab cawv tsis cuam tshuam rau xim thiab saj ntawm cov cawv. Laccase raug ntxiv rau hauv cov txheej txheem kawg ntawm kev tsim npias kom tshem tawm cov tshuaj reactive oxygen thiab polyphenol oxides ntau dhau, yog li ua kom lub txee ntawm npias ntev dua.
