5 Txoj kev kuaj xyuas

6 Flow Chart

Txoj kev npaj ntawm L-aspartic acid muaj xws li cov txheej txheem hluavtaws thiab txoj kev fermentation. 1. Cov txheej txheem synthesis feem ntau yog raws li cov txiv neej acid lossis fumaric acid lossis lawv cov esters, kho nrog ammonia nyob rau hauv siab, thiab tom qab ntawd hydrolyzed. Nws yog qhov yooj yim rau kev sib txuas ntawm racemic aspartic acid, tab sis tam sim no tsis muaj txoj hauv kev zoo tshaj plaws rau kev faib cov racemate. 2. Fermentation method Ntxiv fumaric acid thiab ammonia nyob rau hauv qhov kev txiav txim ntawm enzymes kom tau cov khoom uas muaj siab yield. Txoj kev no tsuas yog tsim L-isomer nrog cov txiaj ntsig siab, yog li nws yog txoj hauv kev tseem ceeb rau kev tsim khoom lag luam. Aspartic acid yog tsim los enzymatically. Siv L-aspartase los ua rau fumaric acid (fumaric acid) thiab ammonia los tsim L-aspartic acid. Kab mob kab mob Escherichia coli (Eschrichiacoli) Asl. Kev cog qoob loo ntawm 881. Ordinary gravy nruab nrab yog slant nruab nrab, thiab muaj pes tsawg leeg ntawm lub raj mis ntxig nruab nrab yog: pob kws steep cawv 7.5 feem pua, fumaric acid 2.0 feem pua ​​, MgSO4 7H2O {{14} }.02 feem pua. Sau qhov nruab nrab nrog 50-100ml ntawm kab lis kev cai nruab nrab. Nqa cov noob qoob loo rau ntawm txoj kab nqes tshiab los yog hauv cov kua, inoculate lawv mus rau hauv lub khob ntim cov kab lis kev cai nruab nrab, co thiab kab lis kev cai ntawm 37 degree rau 24 teev, nthuav cov kab lis kev cai ib kauj ruam mus rau qhov ntsuas ntawm 1000-2000L, kho pH mus rau 5.0 nrog 1mol / L HCl, Tom qab incubating ntawm 45 degree rau 1 teev, txias rau chav tsev kub, thiab centrifuge nyob rau hauv lub nruas hom high-ceev centrifuge mus sau cov kab mob uas muaj aspartase.

L-immobilized aspartase, ua rau hauv bioreactor Siv 20kg ntawm E. coli cov kab mob ntub dej, tshem tawm hauv 8{{10}}L ntawm centrifuged kab lis kev cai supernatant (los yog 80 L ntawm ib txwm saline), ua kom sov ntawm 40 degree, ces ntxiv 90L kom sov ntawm 40 degree 12 feem pua ​​​​gelatin tov thiab 1.0 feem pua ​​glutaraldehyde tov, tom qab tag nrho nplawm, cia nws txias thiab solidify, ces tsau nyob rau hauv 0.25 feem pua ​​glutaraldehyde tov, thiab tom qab hmo ntuj ntawm 5 degree, txiav nws mus rau hauv me me pieces ntawm 3-5mm3 block, thiab tsau nws nyob rau hauv 0.25 feem pua ​​glutaraldehyde tov ntawm 5 degree ib hmos, ces muab nws tawm, ntxuav nws nrog distilled dej, thiab lim kom qhuav kom tau. immobilized E.Coli uas muaj aspartase, uas tau ntim rau hauv cov ntim bioreactor Hauv, seem. Kev hloov pauv tau txais cov tshuaj ntawm 1mol / L ammonium fumarate (muaj 1mmol / LMgCl2, pH8.5) substrate uas khaws cia ntawm 37 degree, thiab ntws los ntawm bioreactor tsis tu ncua ntawm qee qhov chaw tshaj tawm (SV) los tswj qhov siab tshaj plaws hloov pauv ntau dua. 95 feem pua. Kev hloov pauv hloov. Kev npaj thiab purification ntawm crude khoom ntxiv 1mol / L HCl maj mam mus rau lub hloov dua siab tshiab kua, kho cov pH mus rau 2.8, cia nws nyob rau ntawm 5 degree rau hmo ntuj crystallization, lim lub crystallization, ntxuav nrog dej, lim qhuav, thiab qhuav ntawm 105 degree kom tau. L-asparagus Amino acid crude khoom. Tom qab ntawd recrystallize cov khoom crude nrog dilute ammonia dej, ua ntej dissolve nws mus rau hauv 15 feem pua ​​​​tshuaj (pH5.0) nrog ammonia dej, ces ntxiv 1 feem pua ​​activated carbon, tshav kub ntawm 70 degree thiab do rau 1 teev kom decolorize, lim thaum kub rau. tshem tawm cov residue, coj cov lim kom txias, thiab ua kom sov ntawm 5 degree Crystallize thaum hmo ntuj, sau cov muaju los ntawm kev pom, thiab lub tshuab nqus tsev qhuav ntawm 85 degree kom tau cov khoom tiav ntawm L-aspartic acid.
