Chii chinonzi Microbial Dyeing?

Natural pigments ine hunhu hwekuchengetedza, kwete-chepfu, isiri-carcinogenicity uye biodegradation. Microorganisms dzakaparadzirwa zvakanyanya uye dzine hukuru hwakasiyana. Naizvozvo, microbial dyeing ine yakafara application tarisiro mukatitextileindustry.

1.Microbial pigment

Microbial pigment is a second metabolite of microorganisms, iyo ine mavara mazhinji, seyakatsvuka, orenji, yero, yegirini, cyan, yepepuru, dema uye shava, etc. Microbial pigments inogona kukamurwa kuita mhando mbiri, semvura-soluble pigments uye isiri- mvura-soluble pigments. Tichienzanisa nemamwe madhayi echisikigo, madhayi ehutachiona ane nguva pfupi yekugadzira uye mutengo wakaderera, izvo zviri nyore kugadzirwa kwemaindasitiri.

Kune nzira mbiri huru dzekugadzira microbial pigments, sezvidziviriro kubva mukukura kwe microorganisms uye pigments yakagadzirwa nekushandurwa kwechimwe chikamu chetsika yetsika se substrate. Yechipiri, inoda kuwedzera zvimwe zvinhu zvinodiwa pakugadzira pigment mutsika yepakati kukurudzira kugadzirwa kwe pigment uye kuwedzera goho re pigment.

2.Nzira dze microbial dyeing

ExtractDyeing

Iko kushandisa mvura yepakati kune tsika tupukanana kuita kuti ibudise akawanda pigment, uyezve kuwana iyo pigment mhinduro nekuparadzanisa, kudhirowa uye kuisa pfungwa.

Iyo pigment mhinduro inogona kushandiswa zvakananga sedhayi doro, asi zvakare inogona kugadzirwa kuita pigment poda yobva yashandiswa. Kubvisa dhayi kune yakakura application siyana uye iri nyore kugadzira maindasitiri. Asi ine yakaoma kuburitsa maitiro, ayo ane mutengo wakakwira.

Kudhaya kweBacterial Cell

Bacterial cell dyeing yakakamurwa kuita nzira mbiri zvichienderana netsika yemagariro. Imwe ndeye liquid fermentation medium. Kana tupukanana tuchigadzira pigment yakawanda, isina utachionajirainogona kuiswa mukugadzirisa tsika kuve netsika yekudhaya. Imwe yacho yakasimba agar medium. Mushure menguva yekurima, kana ma microorganisms akagadzira akawanda e pigment, masero ebhakitiriya uye yepakati anowedzerwa mvura uye yakabikwa, uye jira rinodhayiwa pa80 ℃.

Bacterial cell dyeing iri nyore, inochengetedza nguva nesimba uye nyore kubata. Asi haina kukodzera kune ma microorganisms anogadzira insoluble pigments.

Microbial madhayi echisikigo ane eco-hushamwari uye ane yakakura kuvirisa tekinoroji uye yakanaka biocompatibility. Vanowedzera mukurumbira pakati pevanhu. Micheka yakadhayiwa nedhayi diki ine mavara akasiyana uye kupenya. Microbial natural dhayi dzine tarisiro huru yekushandisa.
