1.Optically active D-2-hydroxybutanoate inokosha chivako chepakati chemishonga uye biodegradable poly (2-hydroxybutanoate).Kinetic resolution yeracemic 2-hydroxybutanoate inogona kuve yakasvibira uye inodiwa imwe yeD-2-hydroxybutanoate kugadzirwa.Mune basa iri, D-2-hydroxybutanoate pahuwandu hwepamusoro (0.197 M) uye yakakwira enantiomeric yakawandisa (99.1%) yakagadzirwa neNAD-yakasununguka L-lactate dehydrogenase (L-iLDH) ine biocatalyst.2-Oxobutanoate, imwe yakakosha yepakati, yakagadziridzwa pamwe pakakwirira (0.193 M).Uchishandisa nzira iri nyore yekuchinjanisa ion ine macroporous anion exchange resin D301, D-2-hydroxybutanoate yakaparadzaniswa neiyo biotransformation system ine kupora kwakanyanya kwe84.7%.
2.Asymmetric synthesis yeamino acid isiri yakasikwa yakaratidzwa ne omega-transaminase kubva kuVibrio fluvialis JS17.L-2-Aminobutyric acid yakagadzirwa kubva ku2-oxobutyric acid uye benzylamine ine enantiomeric yakawandisa kupfuura 99%.Kuita kwakaratidza kuvharika kwechigadzirwa ne benzaldehyde, iyo yakakundwa nekushandisa biphasic reaction system kubvisa iyo inhibitory chigadzirwa kubva pachikamu chemvura.Muchimiro chebiphasic reaction (50 mM 2-oxobutyric acid, 70 mM benzylamine uye 2.64 U/ml yakanatswa enzyme) vachishandisa hexane sechinhu chinobvisa, kushandurwa kwe2-oxobutyric acid kwakasvika 96% mu5 h asi 39% chete kutendeuka kwakawanikwa pasina. kubviswa kwechigadzirwa.
