Lactic Acid
Enzyymatic txoj kev
(1) kev hloov pauv ntawm chloroproppionate
Honzaki li al. ntawm University of Tokyo siv huv si {{0} Halogenated acid thiab dl {4 3}} chloroprodolionic acid feem ntau los tsim L-lactic acid lossis d-lactic acid. L {{6} ha} halogenated acid dehalogenated acid catalopionic acid tuaj yeem mot}} chloroprodic acid thiab l}} cloroprocionic Acid los ua cov ntawv sau ua ke kho qhov muag, thiab ua tib cov kev teeb tsa kev teeb tsa sib hloov.
(2) pyruvase hloov dua siab tshiab
D-lactate dehydrogenase tau tau los ntawm Lactobacillus chaotic DSM20196, uas tau muaj kev ua haujlwm siab tshaj plaws ntawm lactically dehydrog acid tau los ntawm lub hauv paus ntawm optically tsis ua hauj lwm pyruvate.
Lub ntsiab kev ntawm kev lag luam tsim cov lactic acid yog fermentation thiab synthesis. Vim tias nws cov txheej txheem yooj yim, kev txhim kho thaum ntxov, muaj kev txhawb nqa hauv cov kua qaub ntau dua li 70 feem ntau, tsuas yog muaj kev sib deev lossis ib nrab txuas ntxiv mus , thiab qhov zoo ntawm fermentic fermented lactic acid tsis tuaj yeem ntsib cov qauv thoob ntiaj teb. Kev siv tshuaj lom neeg tuaj yeem ua tiav loj-teev txuas ntxiv khoom ntawm lactic acid tau pom zoo los ntawm Tsoom Fwv thiab Tshuaj Siv Cov Khoom Siv Raw (FDA), tab sis tsis ua raws li qhov yuav tsum tau ua ntawm Green Chemistry. Lub txheej txheem sib xyaw ua ke yog qhov nyuaj, thiab nws daim ntawv thov kev muaj kev lag luam yuav tsum tau kawm ntxiv.
