Ko te 1.Optically active D-2-hydroxybutanoate he mea nui te takawaenga whare mo nga rongoa me te polydegradable poly(2-hydroxybutanoate).Ko te whakataunga kinetic o te racemic 2-hydroxybutanoate he momo kaakaariki me te hiahia mo te hanga D-2-hydroxybutanoate.I roto i tenei mahi, D-2-hydroxybutanoate i te kukū tiketike (0.197 M) me te taikaha enantiomeric tiketike (99.1%) i hanga e te NAD-independent L-lactate dehydrogenase (L-iLDH) kei roto biocatalyst.Ko te 2-Oxobutanoate, tetahi atu takawaenga nui, i hangaia tahi i te kohinga teitei (0.193 M).Ma te whakamahi i te tukanga whakawhiti katote ngawari me te macroporous anion exchange resin D301, D-2-hydroxybutanoate i wehea mai i te punaha biotransformation me te nui o te whakaoranga o 84.7%.
2. Ko te whakahiato hangarite o te waikawa amino rerekee i whakaatuhia e te omega-transaminase mai i te Vibrio fluvialis JS17.Ko te waikawa L-2-Aminobutyric i synthesized mai i te waikawa 2-oxobutyric me te benzylamine me te taikaha enantiomeric teitei ake i te 99%.I whakaatuhia e te tauhohenga te aukati hua nui na te benzaldehyde, i hinga ma te whakamahi i te punaha tauhohenga biphasic hei tango i te hua aukati mai i te wahanga wai.I roto i te tauhohenga biphasic angamaheni (50 mM 2-oxobutyric acid, 70 mM benzylamine me 2.64 U/ml pure enzyme) ma te whakamahi hexane hei tangohanga, ko te hurihanga o te waikawa 2-oxobutyric i tae ki te 96% i roto i te 5 haora engari ko te 39% anake te huringa karekau. te tangohanga hua.
