Qhov sib txawv tseem ceeb ntawm Cyanobacteria thiab Proteobacteria tsis tuaj yeem txiav tawm tshwj xeeb. Txawm li cas los xij, cyanobacteria, hu ua xiav-ntsuab algae, yog cov photosynthetic kiag li thaum cov kab mob proteobacteria tsim los ntawm ntau yam kab mob gram tsis zoo tawm ntawm qee cov kab mob uas yog photosynthetic.
Txawm tias Cyanobacteria thiab Proteobacteria qhia ntau tus yam ntxwv sib xws, raws li lawv lub peev xwm los ua photosynthesize, lawv yuav txawv ntawm ib leeg. Txawm li cas los xij, lawv ob leeg yog cov kab mob tseem ceeb hauv kev lag luam nrog rau cov kab mob uas ua rau muaj kab mob.
Cyanobacteria yog dab tsi?
Cyanobacteria lossis xiav-ntsuab algae yog cov kab mob photosynthetic. Lawv yog cov prokaryotic autotrophs thiab muaj cov xim sib txawv xws li chlorophyll a, phycobilin thiab phycoerythrin. Tsis tas li ntawd, lawv yog cov kab mob unicellular filamentous, thiab qee zaum lawv muaj xws li cyanobacterial blooms. Lawv ua cov haujlwm photosynthetic siv lawv cov plasma membranes.
Cyanobacteria feem ntau muaj nyob rau hauv cov dej tsis qab thiab hauv cov av ntub dej. Lawv qhov loj me txawv ntawm 0.5 - 60 µm. Tsis tas li ntawd, binary fission yog lub ntsiab mechanism ntawm cyanobacterial cell proliferation thiab reproduction. Tsis tas li ntawd, qee yam ntawm cov tsiaj no tau tawg thiab ntau qhov sib cais.
Nitrogen Fixation los ntawm Cyanobacteria
Cyanobacteria muaj cov qauv tshwj xeeb hu ua heterocyst. Heterocyst muaj peev xwm kho nitrogen los ntawm huab cua. Tsis tas li ntawd, cov kab mob Cyanobacterial xws li Anabaena thiab Nostoc muaj peev xwm kho tau cov pa Nitrogen.
Qhov tseem ceeb ntawm Cyanobacteria
Cyanobacteria tau dav siv los ua cov khoom noj khoom haus vim muaj cov khoom noj muaj txiaj ntsig ntawm qee hom Cyanobacterial (Spirulina, Cholerella). Qee cov Cyanobacteria ua haujlwm ua inoculants hauv kev tsim cov txheej txheem biofertilizers. Yog li ntawd, ntau qhov kev sib raug zoo tseem ceeb, hu ua Lichen koom haum, uas tseem ceeb heev hauv kev ua liaj ua teb, muaj nyob nruab nrab ntawm cov fungi thiab Cyanobacteria.
Daim duab 01: Cyanobacteria
Tsis tas li ntawd, Cyanobacteria tsub zuj zuj tuaj yeem ua rau eutrophication hauv cov dej ua rau lawv muaj kuab paug loj hauv dej. Yog li ntawd, Cyanobacteria kuj ua raws li qhov ntsuas ntawm dej paug.
YPab Proteobacteria yog dab tsi?
Proteobacteria yog ib pawg kab mob dav dav uas suav nrog tag nrho cov kab mob Gram Negative. Yog li ntawd, pawg no muaj cov kab mob ntau tshaj plaws. Cov kab mob no muaj ntau yam nta. Qee yam ntawm cov yam ntxwv no suav nrog;
- Muaj peev xwm photosynthesize.
- Muaj peev xwm kho nitrogen
- Ua raws li kab mob pathogenic.
- tuaj yeem ua tau qhov sib txawv ntawm cov qauv morphologies.
- Muaj peev xwm koom nrog ntau lub luag haujlwm metabolic.
Daim duab 02: Proteobacteria
Muaj rau chav kawm tseem ceeb ntawm Proteobacteria; lawv yog,
- Alphaproteobacteria - muaj cov kab mob phototrophic.
- Betaproteobacteria - muaj cov kab mob aerobic lossis facultative. Qee qhov yog chemolithotrophic (Nitrosomonas).
- Gammaproteobacteria - Feem ntau cov kab mob (Salmonella, Vibrio).
- Deltaproteobacteria - Aerobic kab mob. Ib txhia ua raws li leej faj txo cov kab mob.
- Epsilonproteobacteria - Feem ntau yog spirilloid hauv cov duab. (Helicobacter)..
- Zetaproteobacteria- Cov kab mob qhia tau ntau yam yam ntxwv.
Dab tsi zoo sib xws ntawm Cyanobacteria thiab Proteobacteria?
- Cyanobacteria thiab Proteobacteria yog ob qho tib si rau Kingdom Bacteria.
- Ob leeg muaj lub koom haum prokaryotic cellular.
- Qee kab mob ntawm ob pawg muaj peev xwm kho nitrogen.
- ob leeg muaj peev xwm ua tau raws li cov kab mob.
- Lawv ob leeg muaj hom uas ua raws li cov kab mob tseem ceeb hauv kev lag luam.
Qhov txawv ntawm Cyanobacteria thiab Proteobacteria yog dab tsi?
YCyanobacteria vs Proteobacteria |
|
| Cyanobacteria (los yog xiav ntsuab algae) yog ib pawg ntawm cov kab mob uas muaj peev xwm ua kom photosynthesize. | Proteobacteria tsim ntau yam kab mob gram tsis zoo, thiab ntawm cov uas, qee qhov yog photosynthetic. |
| Muaj peev xwm Photosynthesize | |
| Lawv muaj peev xwm ua kom photosynthesize. | Tsuas yog qee hom tsiaj tuaj yeem nkag mus rau photosynthesis. |
| Cell Wall Structure | |
| Lawv tuaj yeem yog Gram Negative lossis Gram Positive. | Tag nrho yog Gram Negative. |
Summary – Cyanobacteria vs Proteobacteria
Ob pawg Cyanobacteria thiab Proteobacteria muaj ntau haiv neeg, yog li ntawd, nws nyuaj heev kom paub qhov txawv ntawm lawv. Raws li cov yam ntxwv qhia los ntawm cov kab mob, cyanobacteria yog cov kab mob photosynthetic tag nrho thaum tsuas yog qee cov kab mob proteobacteria yog photosynthetic. Tsis tas li ntawd, tag nrho cov proteobacteria yog Gram Negative, nyob rau hauv sib piv tsuas yog ib co cyanobacteria yog Gram Negative. Qhov no yog qhov txawv ntawm Cyanobacteria thiab Proteobacteria.
