Ntuj qhov chaw
Glucoamylase yog ib qho tseem ceeb saccharifying enzyme uas tau siv dav hauv cov hmoov txhuv nplej siab ua haujlwm -hydrolyzing txheej txheem. Lub ntuj qhov chaw ntawm glucoamylase feem ntau suav nrog cov kab mob, cov nroj tsuag, thiab cov nplej germinated, ntawm cov microbial qhov chaw yog cov lag luam tseem ceeb tshaj plaws. Cov kab mob fungal xws li Aspergillus niger thiab Rhizopus hom yog nyiam vim lawv cov enzyme siab yield, ruaj khov fermentation kev ua tau zoo, thiab tsim nyog rau kev tswj loj - teev ntau lawm.
Nroj tsuag - muab tau los ntawm saccharifying enzymes yog ib txwm muaj nyob rau hauv germinating nplej xws li barley, pob kws, thiab nplej, uas lawv pab hloov cov hmoov txhuv nplej siab rau hauv cov suab thaj yooj yim thaum lub sij hawm sprouting. Thaum cov chaw cog qoob loo yav dhau los tau pab txhawb rau ib txwm malt-raws li saccharification, kev lag luam niaj hnub no tau hloov mus rau microbial fermentation vim tias nws cov txiaj ntsig zoo dua, zoo dua purity, thiab ruaj khov enzyme tso zis ntau dua. Raws li qhov tshwm sim, fungal fermentation tau dhau los ua txoj hauv kev tseem ceeb hauv ntiaj teb los tsim cov glucoamylase.
Mechanism & Applications
Glucoamylase ua haujlwm los ntawm kev tshem tawm -1,4 glycosidic bonds los ntawm qhov tsis txo qis ntawm cov hmoov txhuv nplej siab, maj mam tso cov piam thaj. Qhov no stepwise hydrolysis ua kom muaj txiaj ntsig ntawm kev hloov pauv ntawm cov carbohydrates nyuaj rau hauv cov suab thaj fermentable, ua rau glucoamylase tseem ceeb hauv cov txheej txheem uas yuav tsum tau muaj cov saccharification siab.
Nws cov ntawv thov tseem ceeb suav nrog kev ua cov hmoov txhuv nplej siab, cawv fermentation, brewing, ci, nplej sib sib zog nqus- ua, thiab syrup ntau lawm. Hauv kev hloov pauv cov hmoov txhuv nplej siab, glucoamylase ua lub luag haujlwm tseem ceeb hauv kev tsim cov qib siab -glucose syrups nrog kev ua tau zoo. Hauv kev lag luam cawv thiab brewing, nws txhawb cov hmoov txhuv nplej siab, txhim kho fermentation efficiency thiab siv suab thaj. Nyob rau hauv ci, lub enzyme txhawb lub khob noom cookie txias thiab ruaj khov fermentation. Thoob plaws hauv cov teb no, glucoamylase muaj nuj nqis rau nws txoj kev ntseeg siab, kev ua haujlwm, thiab kev sib raug zoo nrog cov tshuab niaj hnub no.
Peb Glucoamylase
Peb muab glucoamylase hmoov ua los ntawm submerged fermentation ntawm ua tib zoo xaiv Aspergillus niger hom. Lub enzyme yog refined los ntawm microfiltration, ultrafiltration, thiab lub tshuab nqus tsev khov - ziab, kom ntseeg tau siab purity, zoo ib yam, thiab ruaj khov batch zoo. Cov txheej txheem kev tswj hwm no ua rau peb cov saccharifying enzyme kom tau raws li ntau yam kev lag luam xav tau rau saccharification thiab hmoov txhuv nplej siab.
