1. Mofuta oa reactor
Enzyme e sa tsamaeeng e sebetsa ho ka bobeli kettle batch reactor le bethe e tsitsitseng e tsoelang pele ea ho phalla.Hoa lokela ho hlokomeloa ho qoba ho senya ka lebaka la matla a ka ntle nakong ea ho fepa kapa ho tlatsa.
2. Ho arabela pH, mocheso le solvent
Enzyme e sa tsamaeeng e lokela ho eketsoa qetellong, ka mor'a hore lisebelisoa tse ling li kenngoe le ho qhibiliha, 'me pH e lokisoe.
Haeba tšebeliso ea substrate kapa sebopeho sa sehlahisoa se lebisa phetohong ea pH nakong ea karabelo, buffer e lekaneng e lokela ho eketsoa tsamaisong ea karabelo, kapa pH e lokela ho beoa leihlo le ho lokisoa nakong ea karabelo.
Ka har'a maemo a mamello a mocheso a CALB (ka tlase ho 60 ℃), sekhahla sa phetoho se eketsehile ka ho eketseha ha mocheso.Ka ts'ebeliso e sebetsang, mocheso oa karabelo o lokela ho khethoa ho latela botsitso ba substrate kapa sehlahisoa.
Ka kakaretso, ester hydrolysis reaction e loketse tsamaisong ea metsi, athe ester synthesis reaction e loketse tsamaisong ea organic phase.Mokelikeli oa tlhaho o ka ba ethanol, tetrahydrofuran, n-hexane, n-heptane le toluene, kapa motsoako o tsoakiloeng o loketseng.Bakeng sa karabelo ho li-solvents tse ling, metsi a 3% a ka eketsoa ho ntlafatsa phello ea karabelo.
3. Tšebeliso hape le bophelo ba ts'ebeletso ea CALB
Tlas'a boemo bo nepahetseng ba karabelo, CALB e ka khutlisoa le ho sebelisoa hape, 'me linako tse ikhethileng tsa ts'ebeliso li fapana ho ea ka merero e fapaneng.
Haeba CALB e fumanweng e sa sebediswa hape kamehla mme e hloka ho bolokwa ka mora ho fola, e hloka ho hlatsuwa le ho omiswa le ho kwalwa ka mocheso wa 2-8 ℃.
Kamora ho sebelisoa hape ka makhetlo a 'maloa, haeba ts'ebetso ea karabelo e fokotsehile hanyane, CALB e ka eketsoa ka nepo 'me ea tsoela pele ho sebelisoa.Haeba ts'ebetso ea karabelo e fokotsehile haholo, e hloka ho nkeloa sebaka.
