1.Gukora cyane D-2-hydroxybutanoate nigice cyingenzi cyubaka hagati yimiti na poly biodegradable (2-hydroxybutanoate).Gukemura ibibazo byamoko 2-hydroxybutanoate irashobora kuba icyatsi kandi cyifuzwa muburyo bwa D-2-hydroxybutanoate.Muri iki gikorwa, D-2-hydroxybutanoate yibanda cyane (0.197 M) hamwe na enantiomeric irenze (99.1%) yakozwe na NAD yigenga ya L-lactate dehydrogenase (L-iLDH) irimo biocatalyst.2-Oxobutanoate, ikindi gihe cyingenzi, cyafatanyirijwe hamwe hamwe (0.193 M).Ukoresheje uburyo bworoshye bwo guhanahana ion hamwe na macroporous anion yo guhana resin D301, D-2-hydroxybutanoate yatandukanijwe na sisitemu yo guhindura ibinyabuzima hamwe no gukira kwinshi kwa 84.7%.
2.Asimmetric synthesis ya aside amine idasanzwe yerekanwe na omega-transaminase yo muri Vibrio fluvialis JS17.L-2-Aminobutyric acide yashizwemo kuva aside-2 ya oxobutyric na benzylamine hamwe na enantiomeric irenga 99%.Igisubizo cyerekanye ibicuruzwa bibujijwe na benzaldehyde, byatsinzwe no gukoresha sisitemu ya biphasic reaction kugirango ikure ibicuruzwa bibuza icyiciro cyamazi.Mubisanzwe biphasic reaction (50 mM 2-oxobutyric acide, 70 mM benzylamine na 2.64 U / ml isukuye enzyme) ukoresheje hexane nkikuramo, guhindura aside 2-oxobutyric yageze kuri 96% muri 5 h mugihe ihinduka 39% ryonyine ryabonetse nta gukuramo ibicuruzwa.
