Ntuj pigments muaj cov yam ntxwv ntawm kev nyab xeeb, tsis muaj tshuaj lom, tsis muaj carcinogenicity thiab biodegradation. Cov kab mob kis tau dav dav thiab muaj ntau yam. Yog li ntawd, microbial dyeing muaj dav daim ntawv thov kev cia siab nyob rau hauvtextilekev lag luam.
1.Microbial pigment
Microbial pigment yog cov metabolite thib ob ntawm cov kab mob, uas muaj ntau xim, xws li liab, txiv kab ntxwv, daj, ntsuab, cyan, ntshav, dub thiab xim av, thiab lwm yam. dej-soluble pigments. Piv nrog rau lwm yam ntuj dyes, microbial dyes muaj lub sij hawm luv luv thiab luv nqi, uas yog yooj yim rau industrialized ntau lawm.
Muaj ob txoj hauv kev tseem ceeb los tsim cov kab mob microbial pigments, raws li kev zais cia los ntawm kev loj hlob ntawm cov kab mob thiab cov pigments tsim los ntawm kev hloov pauv ntawm ib feem ntawm kab lis kev cai nruab nrab raws li substrate. Rau qhov thib ob, nws yuav tsum tau ntxiv qee yam tshuaj uas xav tau rau cov pigment ntau lawm hauv cov kab lis kev cai nruab nrab los txhawb cov pigment ntau lawm thiab ua kom cov pigment yield.
2.Txoj kev ntawm microbial dyeing
ExtractDyeing
Nws yog siv cov kua nruab nrab rau kab lis kev cai kab lis kev cai kom lawv tsim ntau cov pigments, thiab tom qab ntawd tau txais cov xim xim los ntawm kev sib cais, rho tawm thiab concentration.
Cov tshuaj pleev xim tuaj yeem siv ncaj qha los ua dye cawv, tab sis kuj tuaj yeem ua rau cov xim xim thiab tom qab ntawd siv. Extract dyeing muaj ntau daim ntawv thov ntau thiab yooj yim rau industrialize. Tab sis nws muaj cov txheej txheem extracting nyuaj, uas muaj tus nqi siab.
Kab mob Cell Dyeing
Bacterial cell dyeing yog muab faib ua ob txoj hauv kev nyob ntawm kab lis kev cai nruab nrab. Ib qho yog kua fermentation nruab nrab. Thaum cov kab mob metabolize ntau cov pigments, lub sterilentaubtuaj yeem muab tso rau hauv kab lis kev cai daws kom muaj kab lis kev cai dyeing. Lwm qhov yog khov agar nruab nrab. Tom qab ib lub sij hawm ntawm kev cog qoob loo, thaum cov kab mob metabolize ntau cov pigments, cov kab mob thiab nruab nrab yog ntxiv dej thiab boiled, thiab cov ntaub yog dyed ntawm 80 ℃.
Bacterial cell dyeing yog qhov yooj yim, uas txuag lub sijhawm thiab lub zog thiab yooj yim rau kev ua haujlwm. Tab sis nws tsis haum rau cov kab mob uas tsim cov pigments insoluble.
Microbial natural dyes yog eco-friendly thiab muaj cov cuab yeej fermentation paub tab thiab zoo biocompatibility. Lawv dhau los ua neeg nyiam. Textiles dyed los ntawm microbial dyes muaj cov xim tshwj xeeb thiab luster. Microbial natural dyes muaj qhov zoo rau kev thov.
