Yuav Ua Li Cas Txo Cov Cuam Tshuam Oxygen Rau Lub Txee Lub Neej Ntawm Cov Khoom Ua Bakery?
Jan 20, 2021
Oxygen yog qhov sib faib tawm cov khoom siv dav hauv qhov thiab nws yog qhov tseem ceeb rau tib neeg kev muaj sia nyob. Cov hu ua txhua yam yog ob rab ntaj ob, thiab oxygen tsis muaj qhov tshwj xeeb. Tshwj xeeb hauv kev soj ntsuam kev lag luam hauv cov zaub mov, feem ntau cov zaub mov ua tsis ncaj thiab xeb nrog oxygen. Muaj feem xyuam, xws li lub zog tsis zoo ntawm cov noob txiv, oxidative kev puas tsuaj ntawm cov txiv hmab txiv ntoo thiab zaub, thiab lwm yam.
Cov pwm thiab ua kom tsis zoo ntawm cov mov ci thiab ncuav khob noom kuj muaj feem xyuam nrog oxygen, vim tias feem ntau cov kab mob me me xav tau oxygen mus rau cov tsiaj txhu, yog li hnub no kuv yuav tham nrog koj hais txog cawv ntawm cov kab mob sib txawv.
1. Khaws cov kab mob aerobic
Hom kab mob no tsuas tuaj yeem loj hlob nyob rau hauv cov kev muaj pa oxygen, muaj lub kaw lus ua pa, siv cov pa oxygen thaum kawg txais cov pa, thiab cov hlwb muaj superoxide dismutase (SOD) thiab catalase. Cov kab mob hu ua fungi thiab kab mob feem ntau yog tso cov kab mob aerobic, xws li Aspergillus oryzae, Acetobacter thiab lwm yam.
2. Cov kab mob microaerobic
Cov kab mob me me uas tuaj yeem loj hlob tau nkaus xwb thaum muaj cov pa oxygen ib nrab tawm siab, dhau ntawm cov pa ntawm txoj pa thiab siv oxygen thaum kawg txais cov pa los tsim lub zog, xws li Zymomorsas thiab Campylobacter.
3. Lub ntsej muag aerobic cov kab mob
Hom kab mob microorganisms tuaj yeem loj hlob thiab tsim muaj nyob hauv aerobic lossis anaerobic chaw, tab sis lawv loj hlob zoo dua hauv cov kab mob aerobic Lawv cia siab rau lub peev xwm ua pa thaum lawv aerobic, thiab tau txais fermentation lossis anaerobic respiration muaj peev xwm thaum tsis muaj oxygen; cov hlwb muaj SOD thiab ntau dua Catalase.
Xws li cov poov xab ua pa aerobic nyob rau hauv ib puag ncig aerobic, fermenting glucose nyob rau hauv hypoxic cov kab mob los tsim cawv thiab carbon dioxide, feem ntau cov kab mob pathogenic uas ua rau tib neeg thiab tsiaj txhu, thiab ntau cov kab mob hauv plab hnyuv, xws li E. coli.
4. Cov kab mob aerobic
Cov kab mob Aerobic tuaj yeem nyob rau anaerobic nyob ntawm cov pa oxygen molecular. Lawv tsis xav tau oxygen rau lawv txoj kev loj hlob. Cov pa oxygen tsis muaj qab hau rau lawv, tab sis nws kuj tseem tsis muaj kev phom sij. Nws tsis muaj lub cim kev ua pa thiab nyob ntawm kev zom fermentation kom tau txais lub zog. Paub li aerobic kam rau ua anaerobes. Cov kab mob lactic acid dav dav yog cov kab mob aerobic, xws li Lactobacillus lactis, Streptococcus lactis, Leuconostoc mesenteroides, thiab Enterococcus faecalis.
5. Cov kab mob Anaerobic
Cov kab mob loj hlob zoo dua nyob rau hauv kev mob hlwb ntau dua li ntawm ib puag ncig aerobic. Molecular oxygen yog cov tshuaj lom rau nws. Lub sij hawm luv luv raug rau huab cua yuav thaiv lawv txoj kev loj hlob thiab tseem tua lawv; nyob rau hauv cov huab cua lossis huab cua uas muaj 10% CO2, hauv cov khoom nruab nrab Nws tsis tuaj yeem loj hlob saum npoo av, thiab tuaj yeem tsuas loj hlob nyob rau hauv qhov chaw tob tob lossis qis redox muaj peev xwm ib puag ncig; lub zog uas xav tau rau kev ua haujlwm hauv lub neej yog muab los ntawm fermentation, anaerobic respiration, cyclic photosynthetic phosphorylation lossis methane fermentation; cov hlwb tsis muaj SOD thiab cov hlwb Feem ntau ntawm cov xim oxidases tsis muaj catalase. Cov kab mob Anaerobic tau muab faib rau qhov xwm, tib neeg thiab tsiaj. Cov tshuaj anaerobes tsis muaj nyob hauv tib neeg thiab tsiaj, tshwj xeeb tshaj yog nyob hauv cov hnyuv, cov kab noj ntawm qhov ncauj, cov pa ntawm txoj hlab ua pa thiab mob txeeb zig.
Los ntawm qhov kev pom ntawm tsib hom kev paub ntawm cov kab mob me me, lav cov kab mob aerobic yog qhov tseem ceeb ntawm cov pwm thiab ua kom tsis zoo ntawm cov mov ci thiab khoom qab zib, tom qab ntawd cov kab mob aerobic thiab cov kab mob sib kis aerobic. Yog li, tswj kev thov qhov pa oxygen los ntawm cov kab mob me me tuaj yeem tswj tau qhov pwm thiab ua kom tsis zoo ntawm cov khoom. Cov.
1) Ntim ntim: tsis siv neeg ntim tshuab lossis phau ntawv ntim tshuab los cais tawm sab nraud oxygen los ntawm.
2) Siv cov ntawv ntim nrog cov huab cua tsis zoo: tshwj xeeb tshaj yog rau cov khoom lag luam nrog lub neej ntev, txo cov roj pauv sab hauv thiab sab nraud ntawm cov khoom ntim.
3) Siv cov ntim ntim ntawm nitrogen: txo cov pa cua hauv cov khoom ntim thiab tsis ncaj qha txo cov pa oxygen.
4) Xaiv qhov tsim nyog deoxidizer: nqus cov pa mus rau hauv cov huab cua hauv cov pob los tsim kom muaj chaw oxygen tsis muaj pa rau cov kab mob me.
Ntxiv nrog rau kev tswj cov pa oxygen, txhua tus yuav tsum tsis txhob muaj kev dav nyob hauv chav tswj hwm ib puag ncig, kev ua haujlwm ntawm cov neeg nyiam huv thiab kev xaiv cov khoom txuag. Tom qab tag nrho, tiv thaiv xeb yog txheej txheem ua haujlwm. Txhua yam teeb meem hauv txhua qhov txuas yuav cuam tshuam rau cov khoom kawg. Thov kawm ntxiv. Hu rau Guangzhou Baiqing Technical Department.
