Qhov sib txawv tseem ceeb ntawm cov khoom hauv lub xeev fermentation thiab submerged fermentation yog tias cov khoom siv hauv xeev fermentation cuam tshuam txog kev cog qoob loo ntawm cov kab mob ntawm cov khoom siv substrate nrog cov ntsiab lus tsis tshua muaj ya raws thaum submerged fermentation suav nrog kev cog qoob loo ntawm cov kab mob hauv cov kua nruab nrab uas muaj ntau dua. tshaj 95% dej ntsiab lus.
Cov kab mob microorganisms muaj txiaj ntsig zoo hauv ntau hom kev lag luam. Cov kab mob thiab cov fungi tshwj xeeb tshaj yog muaj ntau yam kev siv hauv kev lag luam. Cov kab mob yuav tsum tau loj hlob ntawm qhov loj thaum lub sij hawm muaj fermentation txheej txheem kom rho tawm cov khoom tsim nyog uas tshwm sim los ntawm microbial metabolism. Solid-state fermentation thiab submerged fermentation yog ob lub ntsiab ntawm fermentation uas pab tsim cov enzymes industrially. Nyob rau hauv solid-state fermentation, fermentation tshwm sim los ntawm cov kab mob loj hlob ntawm cov khoom substrate thaum nyob rau hauv submerged fermentation, fermentation tshwm sim los ntawm cov kab mob loj hlob hauv cov kua nruab nrab. Txhua txoj kev muaj qhov zoo thiab qhov tsis zoo.
Dab tsi yog Lub Xeev Fermentation?
Lub xeev fermentation yog ib hom fermentation siv nyob rau hauv cov enzyme ntau lawm. Raws li lub npe qhia, fermentation tshwm sim los ntawm cov kab mob loj hlob ntawm cov khoom siv los yog cov khoom siv substrate uas muaj cov dej noo tsawg heev. Ib lub substrate tsis soluble muab cov as-ham xws li carbon, nitrogen, thiab lwm yam, rau kev loj hlob microbes. Microorganisms loj hlob adhered rau cov khoom substrate. Lub xeev fermentation feem ntau siv cov khoom sib xyaw thiab cov khoom sib txawv ntawm kev ua liaj ua teb los yog cov khoom lag luam ntawm kev lag luam xws li nplej husk, nplej bran, qab zib beet pulp, nplej thiab pob kws hmoov, thiab lwm yam. Li no, cov substrates pheej yig dua thiab yooj yim muaj.
Tsis tas li ntawd, filamentous fungi yog cov kab mob zoo tshaj plaws rau cov khoom siv hauv lub xeev fermentation. Tsis tas li ntawd, cov kab mob, cov poov xab thiab lwm yam fungi kuj tuaj yeem loj hlob ntawm cov khoom substrates thiab tuaj yeem siv rau hauv cov txheej txheem fermentation.

Qhov zoo ntawm Lub Xeev Fermentation
Zoo ib yam li lwm cov txheej txheem fermentation, solid-state fermentation kuj muaj ntau yam zoo raws li teev hauv qab no.
- Qhov nruab nrab yog qhov yooj yim, muaj yooj yim, thiab pheej yig
- Substrates xav tau kev kho mob tsawg dua piv rau cov kua dej
- Cov kab mob raug txwv vim tias cov dej noo tsawg
- Forceed aeration feem ntau yooj yim
- Yooj yim thiab txo cov txheej txheem qis qis thiab pov tseg pov tseg
- Cov khoom siv fermentation yooj yim
- High volumetric productivity
Txawm hais tias muaj zog-lub xeev fermentation muab ntau yam zoo, nws kuj muaj ob peb qhov tsis zoo raws li tau teev tseg hauv qab no.
Disadvantages of Solid State Fermentation
- qis noo noo tuaj yeem txwv kev loj hlob ntawm cov kab mob
- Tshem tawm cov cua sov hauv metabolic yog ib qho teeb meem hauv cov nplai loj hauv lub xeev fermentations
- Nyuaj hauv kev saib xyuas cov txheej txheem tsis
Dab tsi yog Submerged Fermentation?
Submerged fermentation yog lwm txoj kev fermentation peb siv hauv kev tsim cov enzymes. Tsis tas li ntawd, nws xav tau lub nkoj loj aseptic fermentation uas tuaj yeem muab qhov chaw tswj xyuas uas muaj qhov zoo tshaj plaws ntawm qhov kub thiab txias, pH, qib ntawm agitation, oxygen concentration, thiab lwm yam., rau kev loj hlob microorganisms. Submerged fermentation tshwm sim nyob rau hauv cov kua nruab nrab uas muaj cov kab mob. Yog li, cov ntsiab lus dej yog siab, thiab tag nrho cov as-ham muaj nyob hauv cov kua nruab nrab rau kev loj hlob ntawm cov kab mob. Qhov tseem ceeb tshaj plaws, cov as-ham yog sib npaug thoob plaws hauv nruab nrab rau cov kab mob hauv submerged fermentation. Kev ntxhov siab ua kom yooj yim rau kev faib tawm ntawm cov as-ham thiab cov kab mob microbial.
Daim duab 02: Submerged Fermentation
Zoo ib yam li cov khoom siv hauv lub xeev fermentation, submerged fermentation kuj muaj qhov zoo thiab qhov tsis zoo raws li tau hais hauv qab no.
zoo
- Yooj yim ntawm kev ntsuas cov txheej txheem tsis
- Txawm kev faib khoom noj thiab cov kab mob
- Muaj peev xwm tswj kev loj hlob
- Muaj cov ntsiab lus dej siab rau kev loj hlob ntawm microbes
Disadvantages
- Kev siv xov xwm kim thiab khoom kim
- txheej txheem nyuaj thiab kim nqes nqes thiab nyuaj rau kev pov tseg pov tseg
- siv zog ntau
Dab tsi yog qhov zoo sib xws ntawm Lub Xeev Fermentation thiab Submerged Fermentation?
- Solid-state fermentation thiab submerged fermentation yog ob hom kev fermentations hauv enzyme ntau lawm.
- Tsis tas li ntawd, cov kab mob ua kom muaj ob txoj hauv kev.
Dab tsi yog qhov txawv ntawm Lub Xeev Fermentation thiab Submerged Fermentation?
Microbes loj hlob rau ntawm qhov chaw ntawm cov khoom hauv lub xeev fermentation thaum microbes loj hlob hauv cov kua nruab nrab hauv submerged fermentation. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lub xeev fermentation thiab submerged fermentation.
Cov hauv qab no qhia txog qhov sib txawv ntawm lub xeev fermentation thiab submerged fermentation.
Summary – Solid State Fermentation vs Submerged Fermentation
Solid-state fermentation siv cov khoom substrate los loj hlob cov kab mob thaum cov dej fermentation siv cov kua nruab nrab los loj hlob cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm lub xeev fermentation thiab submerged fermentation. Lub xeev fermentation tshwm sim nyob rau hauv qis qis qis thaum submerged fermentation tshwm sim nyob rau hauv dej siab.
