Kev tsim cov txheej txheem ntawm Microbial Fermentation

Cov txheej txheem microbial fermentation tau muab faib ua aerobic fermentation thiab anaerobic fermentation raws li cov cai ntawm fermentation tej yam kev mob. Muaj ntau txoj hauv kev rau aerobic fermentation, nrog rau cov kua nplaum kab lis kev cai fermentation, fermentation ntawm ntxeem tau los yog granular khoom nruab nrab nto, thiab aerobic sib sib zog nqus fermentation. Anaerobic fermentation siv anaerobic sib sib zog nqus fermentation. Yog li ntawd, ob qho tib si aerobic thiab anaerobic fermentation tuaj yeem ua tiav los ntawm kab lis kev cai sib sib zog nqus, uas tau ua tiav hauv cylindrical fermentation tso tsheb hlau luam nrog qee qhov piv txwv. Cov txheej txheem kev khiav hauj lwm tuaj yeem muab faib ua cov hauv qab no.
Batch ua haujlwm: Lub substrate yog loaded rau hauv lub tank ib zaug, inoculated nyob rau hauv haum tej yam kev mob rau cov tshuaj tiv thaiv, thiab tom qab ib tug tej lub sij hawm ntawm lub sij hawm, tag nrho cov reactants raug tshem tawm.
Semi batch lag luam: tseem hu ua kwj ntxiv ua haujlwm. Nws yog hais txog thawj qhov kev thauj khoom ntawm qee qhov substrate rau hauv lub tank thiab inoculating nws nyob rau hauv cov xwm txheej tsim nyog los pib cov tshuaj tiv thaiv. Thaum lub sij hawm cov txheej txheem tshuaj tiv thaiv, tshwj xeeb txwv substrates yog pub rau hauv lub reactor los tswj cov concentration ntawm txwv substrates nyob rau hauv lub tank nyob rau hauv ib tug tej yam ntau yam. Cov tshuaj tiv thaiv raug txiav thiab tag nrho cov reactants raug tshem tawm.
Rov ua dua batch ua haujlwm: Tom qab kev ua haujlwm batch tiav, tshem tawm ib feem ntawm cov tshuaj tiv thaiv kab mob, ntxiv qhov seem rov qab rau hauv lub substrate, thiab tom qab ntawd ua haujlwm batch.
Rov ua dua ib nrab batch kev ua haujlwm: Tom qab ua tiav kev khiav haujlwm ntxiv, tshem tawm ib feem ntawm cov tshuaj tiv thaiv kab mob, thiab ntxiv ib qho nyiaj ntawm cov substrate rau qhov seem seem, thiab tom qab ntawd txuas ntxiv ua haujlwm ntxiv.
Kev ua haujlwm tsis tu ncua: Tom qab cov tshuaj tiv thaiv pib, ntawm ib sab, lub substrate yog txuas ntxiv mus rau lub reactor, thiab tib lub sij hawm, cov tshuaj tiv thaiv cov kua tau tawm mus tas li, kom cov txheej txheem cov tshuaj tiv thaiv nyob rau hauv lub xeev ruaj khov, thiab cov tshuaj tiv thaiv. cov xwm txheej tsis hloov nrog lub sijhawm.
