Qhov sib txawv tseem ceeb ntawm Azotobacter thiab Azospirillum yog Azotobacter yog ib hom kab mob uas feem ntau yog aerobic thiab endophytic diazotrophs. Meanwhile, Azospirillum yog ib tug genus ntawm cov nroj tsuag kev loj hlob-txhawb cov kab mob uas yog microaerophilic thiab nto-colonizing kab mob.

Azotobacter thiab Azospirillum yog ob hom kab mob uas tseem ceeb xws li nitrogen fixers hauv av. Lawv yog cov kab mob hauv av uas yog gram-negative. Ntxiv mus, lawv yog cov kab mob dawb-nyob uas koom nrog cov cag ntoo. Lawv txhim kho cov nroj tsuag kev loj hlob thiab kev loj hlob tom qab inoculation. Azotobacter spp yog cov kab mob heterotrophic thiab aerobic, oval lossis spherical kab mob thaum Azospirillum spp yog microaerophilic thiab cov kab mob uas tsis yog-fermentative rod-zoo li tus kab mob.

Azotobacter yog dab tsi?

Azotobacter yog ib hom kab mob uas muaj cov kab mob aerobic, motile, oval lossis spherical, dawb-nyob hauv av kab mob. Tsis tas li ntawd, Azotobacter tsim cov hlwv tuab-walled thiab tuaj yeem tsim cov kua dej ntau ntau. Yog li ntawd, lawv cov cysts yog resistant rau tej yam tsis zoo ib puag ncig. Cov kab mob no ua lub luag haujlwm tseem ceeb hauv kev kho nitrogen thiab koom nrog lub voj voog nitrogen hauv qhov xwm txheej.

Daim duab 01: Azotobacter

Azotobacter hloov atmospheric nitrogen rau ammonia hauv av. Txij li thaum lawv muaj peev xwm kho nitrogen, lawv siv los ua biofertilizers. Ntxiv mus, Azotobacter yog siv los ua zaub mov additives thiab ib co biopolymers.

Azospirillum yog dab tsi?

Azospirillum yog ib hom kab mob microaerophilic, gram-negative, rod-shaped kab mob cuam tshuam nrog cov hauv paus hniav. Lawv feem ntau hu ua cov kab mob cog kev loj hlob. Lawv yog cov feem ntau nto-colonizing kab mob. Yog li ntawd, lawv tsim cov koom haum xoob nrog cov nroj tsuag nto. Zoo ib yam li Azotobacter, Azospirillum spp kuj yog cov tshuaj nitrogen-kho cov kab mob tsis muaj sia nyob. Lawv nyob rau tsev neeg rhodospirillaceae, uas tsis yog-fermentative.

Vim Azospirillum tuaj yeem kho cov nitrogen, nws yog ib qho ntawm cov khoom siv dav dav siv cov kab mob uas tsis muaj nitrogen-kho cov kab mob xws li inoculants, tshwj xeeb tshaj yog rau mov. Nyob rau hauv cov xwm txheej submerged hauv paddy teb, Azospirillum txhim kho cov nplej cog kev loj hlob thiab tawm los.

Dab tsi yog qhov zoo sib xws ntawm Azotobacter thiab Azospirillum?

  • Ob Azotobacter thiab Azospirillum yog cov kab mob uas yog diazotrophs.
  • Lawv yog cov kab mob gram-negative, dawb-nyob kab mob.
  • Ntxiv mus, lawv yog cov kab mob motile.
  • Azotobacter sp thiab Azospirillum yog siv los ua nitrogen-fixing bio-fertilizer.
  • Yog li ntawd, ob qho tib si siv los ua cov kab mob inoculants ua cov nroj tsuag lossis av inoculants.

Qhov txawv ntawm Azotobacter thiab Azospirillum yog dab tsi?

Azotobacter spp yog aerobic thiab endophytic diazotrophs. Hauv qhov sib piv, Azospirilla yog microaerophilic thiab feem ntau ntawm cov kab mob hauv cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Azotobacter thiab Azospirillum. Azotobacter yog ib tug genus ntawm tsev neeg; pseudomonadaceae / azotobacteraceae, thaum Azospirillum yog ib tug genus ntawm rhodospirillaceae. Tsis tas li ntawd, Azotobacter spp yog cov kab mob oval lossis spherical, thaum Azospirillum spp yog cov kab mob zoo li tus pas nrig.

Ntxiv mus, lwm qhov sib txawv ntawm Azotobacter thiab Azospirillum yog Azotobacter spp yog ib qho tseem ceeb xws li nitrogen-fixing inoculants, biofertilizers, zaub mov additives, thiab ib co biopolymers thaum Azospirillum spp tseem ceeb tshaj li cov nroj tsuag kev loj hlob-txhim kho cov kab mob. Tsis tas li ntawd, Azotobacter spp yog endophytic diazotrophs A thaum Azospirilla yog cov kab mob feem ntau ntog-colonizing.

Hauv qab infographic qhia txog qhov sib txawv ntawm Azotobacter thiab Azospirillum.

Summary – Azotobacter vs Azospirillum

Azotobater thiab Azospirillum yog ob hom ntawm cov kab mob tsis muaj sia, kho cov kab mob nitrogen. Lawv yog cov kab mob gram-negative, motile av kab mob uas txhawb cov nroj tsuag kev loj hlob thiab kev loj hlob. Azotobacter spp yog aerobic thiab endophytic diazotrophs. Hauv qhov sib piv, Azospirillum spp yog microaerophilic thiab feem ntau ntawm cov kab mob hauv cov kab mob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm Azotobacter thiab Azosprillium.
