Amfani da Ferulic Acid azaman Substrate

Ferulic acid, wanda aka samo daga tushe kamar shinkafa shinkafa da bran oat, yana nuna kamanceceniya da vanillin kuma yana aiki azaman abin da ake amfani da shi sosai don samar da vanillin.An yi amfani da ƙwayoyin cuta daban-daban kamar Pseudomonas, Aspergillus, Streptomyces, da fungi don samar da vanillin daga ferulic acid.Musamman ma, an gano nau'ikan irin su Amycolatopsis da White-rot fungi a matsayin masu yuwuwar samar da vanillin daga ferulic acid.Yawancin karatu sun bincika samar da vanillin daga ferulic acid ta amfani da ƙwayoyin cuta, hanyoyin enzymatic, da kuma tsarin da ba a iya motsi ba, yana nuna haɓakawa da yuwuwar wannan hanyar.

Haɗin enzymatic na vanillin daga ferulic acid ya ƙunshi maɓallin enzyme feruloyl esterase, wanda ke haifar da hydrolysis na ester bond a cikin ferulic acid, sakin vanillin da sauran abubuwan da suka danganci su.Ta hanyar bincika mafi kyawun adadin vanillin biosynthetic enzymes a cikin tsarin marasa lafiya, masu bincike sun haɓaka ingantaccen nau'in Escherichia coli mai iya juyar da ferulic acid (20mM) zuwa vanillin (15mM).Bugu da ƙari, yin amfani da rashin motsin ƙwayoyin ƙwayoyin ƙwayoyin cuta ya jawo hankali saboda kyakkyawar dacewarsa da kwanciyar hankali a ƙarƙashin yanayi daban-daban.An samar da wata sabuwar dabarar hana motsa jiki don samar da vanillin daga ferulic acid, ta kawar da buƙatar coenzymes.Wannan tsarin ya ƙunshi decarboxylase mai zaman kansa na coenzyme da oxygenase mai zaman kansa na coenzyme wanda ke da alhakin juyar da acid ferulic zuwa vanillin.Haɗin haɗin gwiwar FDC da CSO2 yana ba da damar samar da 2.5 MG na vanillin daga ferulic acid a cikin zagayowar amsawa guda goma, wanda ke nuna misali na farko na samar da vanillin ta hanyar ilimin halittun enzyme mara motsi.

Amfani da Eugenol/Isoeugenol azaman Substrate

Eugenol da isoeugenol, lokacin da aka juyar da bioconversion, suna samar da vanillin da abubuwan da ke da alaƙa da su, waɗanda aka gano suna da aikace-aikace daban-daban da ƙimar tattalin arziƙi.Nazari da yawa sun binciko amfani da gyare-gyaren kwayoyin halitta da kuma abubuwan da ke faruwa ta halitta don haɗa vanillin daga eugenol.An lura da yuwuwar lalata eugenol a cikin ƙwayoyin cuta da fungi daban-daban, gami da amma ba'a iyakance ga Bacillus, Pseudomonas, Aspergillus, da Rhodococcus ba, suna nuna iyawarsu a cikin samar da vanillin na eugenol.Yin amfani da eugenol oxidase (EUGO) a matsayin enzyme don samar da vanillin a cikin yanayin masana'antu ya nuna babban tasiri.EUGO yana nuna kwanciyar hankali da aiki akan kewayon pH, tare da EUGO mai narkewa yana haɓaka aiki da rage lokacin amsawa.Haka kuma, yin amfani da EUGO mara motsi yana ba da damar dawo da biocatalyst a cikin zagayowar amsawa har zuwa 18, wanda ke haifar da haɓaka fiye da ninki 12 a cikin yawan amfanin biocatalyst.Hakazalika, CSO2 enzyme mara motsi na iya haɓaka jujjuyawar isoeugenol zuwa vanillin ba tare da dogara ga coenzymes ba.
