Ngā Pūrongo - Te Hanga Vanillin Taiao Mai i ngā Rauemi Whakahou

I. Kupu Whakataki

Ko te Vanillin tētahi o ngā matū kakara rongonui me te whānui o te whakamahinga o te ao. I ngā wā o mua, i tangohia mai i ngā pīni vanilla, he utu nui, ā, e pāngia ana e ngā wero e pā ana ki te pumau me ngā ngoikoretanga o te mekameka tuku. Heoi, nā te whanaketanga o te hangarau koiora, inā koa i te mara o te whakawhiti koiora moroiti, kua puta mai he wā hou mō te hanga vanillin tūturu. Mā te whakamahi i ngā moroiti mo te whakawhiti koiora o ngā rauemi mata tūturu kua whakaratohia he ara whai hua mō te hanga vanillin. Ehara i te mea ko tēnei huarahi anake e aro ana ki ngā āwangawanga pumau engari e tuku ana hoki i ngā otinga auaha mō te umanga kakara. Kua whakaratohia e te rangahau i whakahaerehia e te SRM Institute of Science and Technology (SRMIST) he arotake whānui o ngā huarahi rerekē ki te hanga koiora o te vanillin me ā rātou tono i roto i te rāngai kai, e whakarāpopoto ana i ngā tikanga rerekē mō te hanga koiora o te vanillin mai i ngā matū rerekē me ōna tono kanorau i roto i te umanga kai.

II. Me pēhea te tiki i te Vanillin tūturu mai i ngā rauemi whakahou

Te Whakamahinga o te Waikawa Ferulic hei Papanga

Ko te waikawa Ferulic, i ahu mai i ngā pūtake pēnei i te parani raihi me te parani oati, he rite te hanganga ki te vanillin, ā, he mea whānuitia te whakamahinga hei matū mua mō te hanga vanillin. He maha ngā momo moroiti pēnei i a Pseudomonas, Aspergillus, Streptomyces, me ngā harore kua whakamahia hei hanga vanillin mai i te waikawa ferulic. He mea nui, kua tautuhia ngā momo pēnei i a Amycolatopsis me ngā harore White-rot hei kaitono pea mō te hanga vanillin mai i te waikawa ferulic. He maha ngā rangahau kua rangahau i te hanga vanillin mai i te waikawa ferulic mā te whakamahi i ngā moroiti, ngā tikanga whākōkī, me ngā pūnaha kore e nekeneke, e whakaatu ana i te maha o ngā mahi me te kaha o tēnei huarahi.

Ko te hanganga whākōkī o te vanillin mai i te waikawa ferulic e uru ana ki te whākōkī matua feruloyl esterase, e whakakorikori ana i te waikura o te here ester i roto i te waikawa ferulic, e tuku ana i te vanillin me ētahi atu hua taha e pā ana. Mā te tūhura i te nui o ngā whākōkī biosynthetic vanillin i roto i ngā pūnaha kore-pūtau, kua whakawhanakehia e ngā kairangahau he momo Escherichia coli recombinant kua whakapaitia e kaha ana ki te huri i te waikawa ferulic (20mM) ki te vanillin (15mM). Hei tāpiri, kua arohia te whakamahinga o te aukati pūtau moroiti nā te mea he pai te hototahitanga koiora me te pumau i raro i ngā āhuatanga rerekē. Kua whakawhanakehia he tikanga aukati hou mō te hanga vanillin mai i te waikawa ferulic, e whakakore ana i te hiahia mō ngā coenzymes. Kei roto i tēnei huarahi te decarboxylase motuhake-coenzyme me te oxygenase motuhake-coenzyme e kawenga ana mō te hurihanga o te waikawa ferulic ki te vanillin. Mā te whakakotahitanga o te FDC me te CSO2 ka taea te whakaputa i te 2.5 mg o te vanillin mai i te waikawa ferulic i roto i ngā huringa tauhohenga tekau, he tauira paionia tēnei o te whakaputanga vanillin mā te hangarau koiora whākōkī kua whakakotahitia.

Te Whakamahinga o te Eugenol/Isoeugenol hei Papatūānuku

Ina hurihia te eugenol me te isoeugenol ki te koiora, ka puta te vanillin me ōna matū whai pānga, ā, kua kitea he maha ngā whakamahinga me te uara ōhanga nui. He maha ngā rangahau kua tūhura i te whakamahinga o ngā moroiti kua whakarerekētia te ira me ngā moroiti tūturu hei hanga vanillin mai i te eugenol. Kua kitea te kaha o te pirau o te eugenol i roto i ngā momo huakita me ngā harore, tae atu ki a Bacillus, Pseudomonas, Aspergillus, me Rhodococcus, e whakaatu ana i tō rātou kaha ki te hanga vanillin i ahu mai i te eugenol. Ko te whakamahinga o te eugenol oxidase (EUGO) hei whākōkī mō te hanga vanillin i roto i te taiao ahumahi kua whakaatu i te kaha nui. He pumau me te mahi a te EUGO i runga i te whānuitanga pH whānui, me te EUGO wairewa e whakanui ake ana i te mahi me te whakaiti i te wā tauhohenga. Heoi anō, mā te whakamahinga o te EUGO kua kore e neke ka taea te whakaora i te biocatalyst i roto i te 18 huringa tauhohenga, ka hua ake he pikinga neke atu i te 12-ngā wā i roto i te hua biocatalyst. Waihoki, ka taea e te whākōkī CSO2 kua whakapūmau te whakatairanga i te hurihanga o te isoeugenol ki te vanillin, me te kore e whakawhirinaki ki ngā coenzymes.

Ētahi atu Papanga

Haunga te waikawa ferulic me te eugenol, kua tautuhia ētahi atu matū pēnei i te waikawa vanillic me te C6-C3 phenylpropanoids hei matū pea mō te hanga vanillin. Ko te waikawa vanillic, i hangaia hei hua taha o te pakaru o te lignin, hei wāhanga rānei e whakataetae ana i ngā ara pākia, e kiia ana he matū matua mō te hanga vanillin e ahu mai ana i te koiora. Hei tāpiri, ko te whakarato māramatanga ki te whakamahinga o ngā C6-C3 phenylpropanoids mō te hanga vanillin he whai wāhitanga ahurei mō te auahatanga reka pumau me te auaha.

Hei whakamutunga, ko te whakamahinga o ngā rauemi whakahou mō te hanga vanillin tūturu mā te whakawhiti koiora irahiko he whanaketanga nui i roto i te umanga reka. Mā tēnei huarahi ka tukuna he ara rerekē, he ara pumau mō te hanga vanillin, e aro ana ki ngā āwangawanga mō te pumau me te whakaiti i te whakawhirinaki ki ngā tikanga tango tuku iho. Ko ngā tono kanorau me te uara ōhanga o te vanillin puta noa i te umanga kai e whakaatu ana i te hiranga o te rangahau me te whanaketanga tonu i tēnei wāhanga. Ko ngā whanaketanga ā muri ake nei i roto i te mara o te hanga vanillin tūturu he kaha ki te huri i te umanga reka, e whakarato ana i ngā huarahi rerekē pumau me te hoa-taiao mō te auahatanga reka. I a mātou e whakamahi tonu ana i te kaha o ngā rauemi whakahou me ngā whanaketanga hangarau koiora, ko te hanga vanillin tūturu mai i ngā matū kanorau he huarahi whai hua mō te auahatanga reka pumau.
