Biomineralization yog txheej txheem uas cov kab mob muaj sia tsim cov zaub mov.Kev tsim cov khoom lag luam ntxiv ntawm cov biominerals los ntawm microbes muaj peev xwm rau ntau yam kev siv bioengineering.Piv txwv li, kev kho kom tawg thiab txhim kho kev ua haujlwm ntawm cov pob zeb ua kom muaj zog yog lub hom phiaj tseem ceeb rau cov engineers thiab biomineral-tsim microbes tuaj yeem yog cov cuab yeej tseem ceeb hauv kev ua tiav lub hom phiaj no.Ntawm no peb qhia txog kev sib cais, biochemical characterization thiab molecular identification ntawm Pseudomonas azotoformans, microbe uas tsim calcite thiab uas yuav siv tau los kho cov kab nrib pleb hauv cov pob zeb ua vaj tse.Thaum pib, 38 kab mob sib cais tau cais tawm ntawm cov av thiab cov cement.Raws li kev sim thawj zaug, cov kev sib cais tau raug tshuaj xyuas los ntawm kev soj ntsuam urease tom qab kuaj biochemical rau tus nqi ntawm urea hydrolysis, calcite ntau lawm thiab insolubility ntawm calcite.Molecular amplification thiab sequencing ntawm 16S rRNA fragment ntawm cov kev xaiv cais tau tso cai rau peb txheeb xyuas P. azotoformans ua tus neeg sib tw zoo rau p reparation ntawm biotechnological pob zeb.Cov tsiaj no tau raug cais tawm ntawm cov av thiab cov txiaj ntsig tau pom tias ntawm cov kev sim cais nws muaj qhov siab tshaj plaws ntawm urea hydrolysis, tsim cov calcite ntau tshaj plaws, uas, ntxiv rau yog cov nplaum ntau tshaj plaws thiab insoluble.Cov tsiaj no yog li kev txaus siab ua tus neeg sawv cev nrog lub peev xwm los kho cov kab nrib pleb hauv pob zeb.
