Batch Fermentation

Batch fermentation, tseem hu ua batch kab lis kev cai, yog ib txoj hauv kev batch fermentation hauv kev lag luam fermentation uas siv ib lub tank sib sib zog nqus batch fermentation txoj kev. Txhua batch fermentation txheej txheem undergoes inoculation, kev loj hlob thiab kev loj hlob, kab mob senescence, thiab ces xaus fermentation, thaum kawg extracting cov khoom. Cov txheej txheem no yog tswj hwm los ntawm qee cov kab lis kev cai nruab nrab, thiab cov kab mob kis mus rau ntau theem ntawm kev hloov pauv txij thaum yug mus txog rau qhov tuag. Hauv txhua theem ntawm kev hloov pauv, lawv raug txwv los ntawm cov yam ntxwv ntawm cov kab mob lawv tus kheej thiab tseem cuam tshuam los ntawm ib puag ncig ib puag ncig. Tsuas yog los ntawm kev nkag siab kom raug thiab ua tiav qhov kev hloov pauv no tuaj yeem tswj hwm kev tsim khoom fermentation.
Cov yam ntxwv ntawm batch fermentation yog hais tias ib puag ncig nyob rau hauv uas cov kab mob nyob rau hauv tas li hloov, thiab ib tug me me ntawm ntau yam ntawm fermentation ntau lawm yuav nqa tawm. Nyob rau hauv qhov xwm txheej ntawm kev sib kis los ntawm lwm yam kab mob, kev ua haujlwm tuaj yeem raug txiav tawm yooj yim. Thaum cov kev ua haujlwm hloov pauv lossis cov khoom tshiab yuav tsum tau tsim, cov tswv yim fermentation tau hloov tau yooj yim, thiab cov kev xav tau ntawm cov khoom siv raw khoom yog qhov dav.
Cov txheej txheem kev loj hlob ntawm microbial nyob rau hauv batch kab lis kev cai yuav muab faib ua plaub theem: stagnation (los yog hloov) theem, logarithmic (loj hlob) theem, ruaj khov theem, thiab lwj theem. Txoj kev tshawb no ntawm cell metabolism thiab noob caj noob ces yuav tsum siv logarithmic theem cell uas muaj zog loj hlob. Hauv kev tsim cov kev lag luam fermentation, cov noob siv yuav tsum nyob rau theem logarithmic. Thaum lawv inoculated rau hauv cov kab lis kev cai tshiab nruab nrab ntawm lub tank fermentation, yuav luag tsis muaj lub sij hawm stagnation, uas tuaj yeem tau txais cov kab mob loj zuj zus hauv lub sijhawm luv luv, uas muaj txiaj ntsig zoo rau kev ua kom luv luv. Hauv kev tshawb fawb thiab kev tsim khoom, feem ntau nws yog qhov tsim nyog los txuas ntxiv lub logarithmic kev loj hlob theem ntawm cov hlwb.
