Qhov Tseem Ceeb Qhov txawv - Biodegradation vs Bioremediation
Ntau tus kab mob thiab cov kab mob fungal muaj peev xwm ntawm degrading organic pollutants nyob rau hauv ib puag ncig. Biodegradation yog ib qho microorganism-mediated decomposition ntawm cov organic teeb meem. Bioremediation yog txheej txheem siv los ntawm tib neeg los ntxuav cov organic teeb meem thiab lwm yam tshuaj los ntawm kev siv cov microbes nrog cov txheej txheem biodegradation. Qhov sib txawv tseem ceeb ntawm biodegradation thiab bioremediation yog tias biodegradation yog txheej txheem ntuj tsim nyob rau hauv ib puag ncig thaum bioremediation yog cov txheej txheem tsim los ntawm tib neeg los ntxuav ib puag ncig. Ob txheej txheem yog tswj hwm los ntawm cov kab mob.
Biodegradation yog dab tsi?
Cov kab mob microorganisms ua lub luag haujlwm tseem ceeb hauv kev decomposition ntawm cov ntaub ntawv organic uas nyob hauv ib puag ncig. Lawv yog cov recyclers ntawm cov as-ham hauv av. Yuav luag txhua lub voj voog biogeochemical yog tsav los ntawm cov neeg hauv paus txawm microbial hauv av. Biodegradation yog cov txheej txheem uas cov organic tebchaw degraded los yog tawg los ntawm cov kab mob. Nws yog ib qho tseem ceeb ntawm cov txheej txheem uas muab cov khoom noj ntxiv rau ib puag ncig. Microorganisms degrade cov khoom siv organic rau lawv txoj kev loj hlob thiab cov metabolism. Yog li ntawd, cov organic complex tau hloov mus ua carbon dioxide thiab dej.
Muaj ob hom kev biodegradation: aerobic biodegradation thiab anaerobic biodegradation. Aerobic biodegradation yog ua los ntawm cov kab mob aerobic thaum muaj cov pa oxygen txaus rau lawv cov haujlwm. Aerobic biodegradation yog ib txoj kev sai uas degrades cov kab mob tag nrho thaum piv rau anaerobic biodegradation. Anaerobic biodegradation tshwm sim thaum tsis muaj oxygen. Nws txoj kev muaj plaub theem loj: hydrolysis, acidogenesis, acetogenesis thiab methanogenesis. Organic tshuaj yog raug rau anaerobic digestion thiab hloov mus rau carbon dioxide thiab methane.

YYam Bioremediation yog dab tsi?
Bioremediation yog txheej txheem uas siv cov kab mob lossis cov nroj tsuag los ntxuav qhov chaw qias neeg. Cov kab mob tshwm sim los yog qhia txog kab mob, tshwj xeeb tshaj yog cov kab mob microorganisms, uas rhuav tshem ib puag ncig cov pa phem tuaj yeem siv rau hauv bioremediation. Lub hom phiaj tseem ceeb ntawm bioremediation yog hloov cov khoom phom sij rau hauv cov tshuaj tsis muaj tshuaj lom lossis tsawg dua cov tshuaj lom neeg siv cov tshuaj lom neeg. Bioremediation thev naus laus zis tuaj yeem muab faib ua ob pawg tseem ceeb xws li hauv thaj chaw bioremediation thiab ex situ bioremediation. Cov kab mob sib kis tau tawg rau ntawm qhov chaw ntawm qhov pib hauv qhov chaw bioremediation. Qee yam kab mob raug kho tawm ntawm qhov chaw kis kab mob. Hom bioremediation no hu ua ex situ bioremediation.
Bioremediation yog ib txoj hauv kev biotechnological rau kev tswj cov pa phem ib puag ncig. Lub ntuj biodegradable muaj peev xwm ntawm cov tshuaj lom neeg xws li kab mob, fungi, nroj tsuag yog tshawb fawb hauv bioremediation. Bioremediation suav nrog kev tswj hwm ntawm ib puag ncig tsis zoo xws li pH, qhov kub thiab txias, cov ntsiab lus noo noo, thiab lwm yam kom tau txais kev loj hlob zoo ntawm cov kab mob thiab ua kom muaj kev degradation ntau dua. Qee qhov piv txwv ntawm cov thev naus laus zis no yog phytoremediation, bioventing, bioleaching, landfarming, bioreactor, composting, bioaugmentation, thiab biostimulation, thiab lwm yam.

Summary – Biodegradation vs Bioremediation
Biodegradation yog lub peev xwm ntawm cov kab mob kom decompose cov ntaub ntawv organic hauv ib puag ncig. Cov kab mob thiab cov fungi yog cov paub zoo decomposers nyob rau hauv cov av uas yuav pab tau recycle cov ntsiab lus nyob rau hauv ib puag ncig. Feem ntau ntawm cov pa phem yog degraded tag nrho los ntawm aerobic biodegradation nyob rau hauv lub xub ntiag ntawm oxygen. Anaerobic biodegradation yog ua nyob rau hauv ib puag ncig tsis muaj oxygen. Bioremediation yog ib txoj hauv kev biotechnological uas siv cov tshuaj lom neeg los ntxuav cov kab mob hauv ib puag ncig. Hauv bioremediation, cov kab mob tau nkag mus rau qhov chaw kis kab mob los yog txhim kho cov kab mob hauv lub cev los ntawm kev muab cov kev loj hlob tsim nyog. Bioremediation siv lub peev xwm biodegrading ntawm cov kab mob kom ceev cov txheej txheem ntxuav ib puag ncig. Nov yog qhov txawv ntawm
