Qhov txawv ntawm Nitrosomonas thiab Nitrobacter yog Nitrosomonas yog cov kab mob uas hloov ammonium ions lossis ammonia rau hauv nitrites thaum Nitrobacter yog cov kab mob uas hloov nitrite rau nitrates hauv av.
Lub voj voog nitrogen yog lub voj voog biogeochemical tseem ceeb. Nitrogen voj voog tshwm sim ntawm plaub txheej txheem loj: nitrogen fixation, ammonification, nitrification thiab denitrification. Av microorganisms koom nrog feem ntau cov tshuaj tiv thaiv nyob rau hauv lub voj voog nitrogen thiab hloov atmospheric nitrogen rau hauv cov ntaub ntawv siv tau. Nitrification yog kev hloov pauv lom ntawm ammonia lossis ammonium ions rau hauv nitrates los ntawm oxidation. Nws yog ib feem tseem ceeb ntawm lub voj voog nitrogen. Nws tau yooj yim los ntawm ob hom kab mob chemoautotrophic hu ua Nitrosomonas thiab Nitrobacter. Lawv ua haujlwm nyob rau hauv aerobic mob. Nitrification yog pib los ntawm Nitrosomonas. Nitrosomonas hloov ammonia thiab ammonium ions rau hauv nitrite. Tom qab ntawd, Nitrobacter hloov nitrite rau nitrate.
Nitrosomonas yog dab tsi?
Nitrosomonas yog ib hom kab mob nitrifying kab mob. Nitrosomonas hom yog Gram-negative thiab qws-zoo li tus. Lawv yog cov kab mob chemoautotrophic uas hloov ammonium ions thiab ammonia rau hauv nitrite ions hauv av. Yog li ntawd, Nitrosomonas ua lub luag haujlwm tseem ceeb hauv lub voj voog nitrogen.
Daim duab 01: Nitrosomonas spp.
Nitrosomonas hom ua haujlwm nyob rau hauv aerobic mob thiab zoo pH ntawm 7.5 txog 8.5. Ntxiv mus, Nitrosomonas spp muaj polar flagella; yog li ntawd, lawv yog cov kab mob motile. Lawv nyob rau ib pawg ntawm beta proteobacteria.
Nitrobacter yog dab tsi?
Nitrobacter yog ib hom kab mob gram-negative nitrifying bacteria. Nitrobacter hom hloov nitrite hauv av rau hauv nitrates. Qhov no yog ib kauj ruam tseem ceeb ntawm lub voj voog nitrogen. Tsis tas li ntawd, nws yog ib qho tseem ceeb ntawm cov zaub mov ntawm cov nroj tsuag. Nitrate yog daim ntawv siv tau ntawm nitrogen ntawm cov nroj tsuag.
Daim duab 02: Nitrobacter spp.
Nitrobacter nyob ntawm Nitrosomonas rau nws qhov chaw nitrogen. Yog li ntawd, ob qho tib si Nitrosomonas thiab Nitrobacter yog cov kab mob tseem ceeb heev rau cov khoom noj cog qoob loo. Nitrobacter hom muaj sub-terminal flagella. Yog li ntawd, lawv yog cov kab mob motile. Ntxiv mus, Nitrobacter belongs rau alpha subclass ntawm proteobacteria.
Dab tsi zoo sib xws ntawm Nitrosomonas thiab Nitrobacter?
- Nitrosomonas thiab Nitrobacter yog ob yam kab mob chemoautotrophic pom hauv av thiab dej.
- Lawv koom nrog oxidizing ammonia rau hauv nitrate.
- Yog li ntawd, lawv yog cov kab mob nitrifying.
- Lawv ua haujlwm zoo tshaj plaws ntawm qhov zoo tshaj pH ntawm 7.5 txog 8.5.
- Nitrobacter pejxeem muaj kev vam khom rau cov pejxeem ntawm Nitrosomonas.
- Ob tus kab mob no nkag siab rau ntau qhov chaw ib puag ncig xws li pH, yaj oxygen concentration, kub, thiab tshuaj tiv thaiv, thiab lwm yam.
- Ob tus kab mob no zoo li tus pas nrig.
- Ntxiv mus, lawv yog cov kab mob Gram-negative.
- Ob leeg siv CO2 ua lawv cov pa roj carbon.
- Lawv rov tsim dua los ntawm binary fission.
Qhov txawv ntawm Nitrosomonas thiab Nitrobacter yog dab tsi?
Qhov sib txawv tseem ceeb ntawm Nitrosomonas thiab Nitrobacter yog Nitrosomonas koom nrog hauv thawj kauj ruam ntawm nitrification, uas yog kev hloov pauv ntawm ammonia rau hauv nitrites, thaum Nitrobacter koom nrog qib thib ob ntawm nitrification, uas yog kev hloov pauv ntawm nitrite rau nitrates.. Nitrosomonas belongs rau pab pawg ntawm beta proteobateria thaum Nitrobacter belongs rau pawg alpha proteobacteria. Yog li, qhov no yog lwm qhov sib txawv ntawm Nitrosomonas thiab Nitrobacter.
Hauv qab infographic qhia txog qhov sib txawv ntawm Nitrosomonas thiab Nitrobacter hauv daim ntawv teev npe rau ib sab ntawm kev sib piv.
Summary – Nitrosomonas vs Nitrobacter
Nitrification yog hloov pauv ntawm ammonium ions lossis ammonia rau nitrate ions hauv av. Nws yog txheej txheem ob-kauj ruam. Ua ntej, Nitrosomonas hloov ammonium ions rau hauv nitrite. Tom qab ntawd, Nitrobacter hloov nitrite ions mus rau nitrate ions. Qhov no yog ib kauj ruam tseem ceeb hauv cov zaub mov cog txij thaum nitrate (NO 3–) yog cov nroj tsuag siv tau cov nitrogen. Nitrosomonas belongs rau beta subclass ntawm proteobacteria thaum Nitrobacter belongs rau alpha subclass ntawm proteobacteria. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm Nitrosomonas thiab Nitrobacter.
