Pseudomonads tsim ntau ntau ntawm cov tshuaj tiv thaiv kab mob xws li 2,4-diacetylphloroglucinol (DAPG), uas muaj qhov dav-spectrum antagonistic nyhuv tawm tsam phytopathogens. Rhizospheric av qauv tau sau los ntawm Solanaceous cov qoob loo rau kev sib cais ntawm fluorescent pseudomonads (FPs). Tawm ntawm 32 fluorescent kab mob cais tawm, 21 tau pom tias muaj kev tawm tsam tiv thaiv Ralstonia solanacearum yog tsob ntoo me me (NAIMCC-B-01630) nrog thaj tsam siab tshaj plaws ntawm inhibition ntawm 38.33 hli. Ntawm lawv, 11 cov kab mob sib cais tau piav qhia txog kev tsim cov DAPG hauv Kings 'B nruab nrab. DAPG ntau lawm tau kuaj pom los ntawm TLC thiab ntsuas los ntawm HPLC tsom xam. Ntxiv mus, cov kab mob cais OD13 nthuav tawm ntau dua DAPG ntau lawm. Tsis tas li ntawd, lub xub ntiag ntawm DAPG-encoding phlD noob nyob rau hauv qhov loj ntawm 629 bp thiab 725 bp kuj tau lees paub los ntawm kev nthuav dav. Cov kab mob no cais tawm mus rau genera Pseudomonas Raws li kev pom zoo los ntawm morpho-physiological characterization siv VITEK 2 system. Qhov siab dua DAPG-ua cov kab mob cais tawm tau txheeb xyuas raws li Pseudomonas aeruginosa los ntawm polyphasic mus kom ze nrog GenBank tus lej OQ781265. Yog li, DAPG-tsim rhizospheric Pseudomonas Cov kab mob tuaj yeem siv los ua cov tshuaj biocontrol rau cov kab mob wilt. Txawm li cas los xij, kev kawm hauv cheeb tsam yog qhov tseem ceeb heev ua ntej nws daim ntawv thov ua tiav.
