Cov kab mob yog anaerobic thiab nitrogenase yog nquag (ua haujlwm). … Rhizobia tsis tuaj yeem kho nitrogen thaum tsis muaj tus tswv thiab yog li, nitrogenase tseem tsis ua haujlwm. Cov lus teb tiav: Rhizobium yog cov kab mob uas xav tau kev sib raug zoo symbiotic los kho nitrogen. Nws yog aerobe, qws zoo li lub xov tooj ntawm tes thiab cov kab mob gram-negative.
Qhov twg ntawm cov enzyme hauv qab no tsis ua haujlwm hauv Rhizobium?
Nitrogase yog cov enzyme uas tsis ua haujlwm hauv Rhizobium hauv theem ywj pheej.
YPuas Rhizobium tsim nitrogenase?
Cov kab mob Rhizobium los yog Bradyrhizobium colonize tus tswv tsev cov hauv paus system thiab ua rau cov hauv paus hniav tsim nodules rau tsev cov kab mob (Daim duab 4). Cov kab mob ces pib kho cov nitrogen xav tau los ntawm cov nroj tsuag. … Extensive nodulation ntawm txiv laum huab xeeb hauv paus tom qab inoculation nrog Bradyrhizobium strain 32H1.
txheej txheem ntawm Rhizobium yog dab tsi?
Rhizobium kis cov hauv paus hniav ntawm cov nroj tsuag leguminous Lawv feem ntau pom hauv av thiab tsim cov nodules tom qab kis cov hauv paus hniav ntawm cov nroj tsuag leguminous. Yog li ntawd, nitrogen gas yog tsau los ntawm cov cua. Cov nitrogen no tau tsim muaj rau cov nroj tsuag uas pab lawv txoj kev loj hlob thiab kev loj hlob.
Puas yog Rhizobium aerobic lossis anaerobic?
Rhizobium yog ib yam kab mob aerobic bacterium. Lawv yog cov genus ntawm Gram-negative, av, pas nrig-zoo li nitrogen-fixing kab mob.
