Hoʻokuʻu ʻia ʻo CALB
Hoʻokuʻu ʻia ʻo CALB e ka adsorption kino ma ka resin hydrophobic kiʻekiʻe he macroporous, styrene/methacrylate polymer.He kūpono ka Immobilized CALB no nā noi i nā mea hoʻoheheʻe organik a me nā ʻōnaehana solvent-free, a hiki ke hana hou a hoʻohana hou ʻia no nā manawa he nui i nā kūlana kūpono.
Huahana Huahana: SZ-CALB- IMMO100A, SZ-CALB- IMMO100B.
★ ʻoihana kiʻekiʻe, koho kiral kiʻekiʻe a ʻoi aku ka paʻa.
★ ʻoi aku ka maikaʻi o ka hana ma nā pae wai ʻole.
★E wehe maʻalahi mai ka ʻōnaehana pane, hoʻopau wikiwiki i nā hopena, a pale i ke koena protein i loko o ka huahana.
★Hiki ke hana hou ʻia a hoʻohana hou ʻia e hōʻemi i ke kumukūʻai.
Ka hana | ≥10000PLU/g |
ka pae pH no ka pane | 5-9 |
Kaulana wela no ka pane | 10-60 ℃ |
Ka nana aku | CALB-IMMO100-A: Melemele māmā a paʻa ʻeleʻele CALB-IMMO100-B: Paʻa keʻokeʻo a ʻeleʻele māmā |
Nui ʻāpana | 300-500μm |
Pohō ma ka maloʻo ʻana ma 105 ℃ | 0.5%-3.0% |
Resin no ka immobilization | Macroporous, styrene/metacrylate polymer |
Mea hoʻoheheʻe pane | ʻO ka wai, ka mea hoʻoheheʻe organik, etc., a i ʻole ka solvent.No ka pane ʻana i kekahi mau mea hoʻoheheʻe organik, hiki ke hoʻohui ʻia ka 3% wai e hoʻomaikaʻi i ka hopena hopena |
Nui ʻāpana | CALB-IMMO100-A: 200-800 μm CALB-IMMO100-B: 400-1200 μm |
Wehewehe ʻāpana: 1 ʻāpana pili i ka synthesis o 1μmol i kēlā me kēia minuke propyl laurate mai lauric acid a me 1-propanol ma 60 ℃.ʻO ka CALB-IMMP100-A a me CALB-IMMO100-B i luna e pili ana i nā mea lawe immobilized me nā ʻāpana ʻokoʻa.
1. ʻAno Reactor
Ua pili ka enzyme immobilized i ka kettle batch reactor a me ka moena hoʻomau kahe mau.Pono e hoʻomaopopo ʻia e pale i ka ʻoki ʻana ma muli o ka ikaika o waho i ka wā hānai a hoʻopiha.
2. ʻO ka pH, ka mahana a me ka solvent
Pono e hoʻohui hope ʻia ka enzyme immobilized, ma hope o nā mea ʻē aʻe i hoʻohui ʻia a hoʻoheheʻe ʻia, a hoʻoponopono ʻia ka pH.
Inā ʻo ka hoʻohana ʻana i ka substrate a i ʻole ka hoʻokumu ʻana o ka huahana e alakaʻi i ka hoʻololi ʻana o ka pH i ka wā o ka hopena, pono e hoʻohui ʻia ka buffer i ka ʻōnaehana pane, a i ʻole e nānā ʻia ka pH a hoʻoponopono ʻia i ka wā o ka hopena.
I loko o ka palena wela o ka CALB (ma lalo o 60 ℃), ua hoʻonui ʻia ka hoʻololi ʻana me ka piʻi ʻana o ka mahana.I ka hoʻohana pono ʻana, pono ke koho ʻia ka mahana hopena e like me ke kūpaʻa o ka substrate a i ʻole ka huahana.
ʻO ka maʻamau, kūpono ka hopena hydrolysis ester i ka ʻōnaehana aqueous phase, aʻo ka hopena synthesis ester i kūpono i ka ʻōnaehana pae.Hiki i ka mea hoʻoheheʻe organik ke ethanol, tetrahydrofuran, n-hexane, n-heptane a me toluene, a i ʻole he mea hoʻoheheʻe hui ʻia.No ka pane ʻana i kekahi mau mea hoʻoheheʻe organik, hiki ke hoʻohui ʻia ka 3% wai e hoʻomaikaʻi i ka hopena hopena.
3. Hoʻohana hou a me ke ola lawelawe o CALB
Ma lalo o ke kūlana hopena kūpono, hiki ke hoʻihoʻi a hoʻohana hou ʻia ka CALB, a ʻokoʻa nā manawa noi kikoʻī me nā papahana like ʻole.
Inā ʻaʻole hoʻohana mau ʻia ka CALB i hoʻihoʻi ʻia a pono e mālama ʻia ma hope o ka hoʻihoʻi ʻana, pono e holoi a maloʻo a hoʻopaʻa ʻia ma 2-8 ℃.
Ma hope o kekahi mau pōʻai o ka hoʻohana hou ʻana, inā hoʻemi iki ka hopena o ka hopena, hiki ke hoʻohui pono ʻia ka CALB a hoʻomau i ka hoʻohana.Inā hoʻemi nui ka hopena o ka hopena, pono e hoʻololi.
