Imikhiqizo

I-Bacillus amyloliquefaciens iyi-bacterium ye-Gram-positive enesitshalo enenzuzo ebandakanyekayo ekucindezeleni amagciwane athwalwa enhlabathini ngokukhishwa kwama-metabolites esibili kanye nekhono eliphezulu le-rhizosphere.Ukwakhiwa kwe-Biofilm kuthathwa njengento edingekayo ukuze kube nekhono eliphezulu le-rhizosphere.Kulo msebenzi, sibonisa ukuthi izitshalo ezikhishwe izitshalo zithinta ukwakheka kwe-chemotaxis kanye ne-biofilm ye-B. amyloliquefaciens SQY 162 (SQY 162).Wonke ama-carbohydrate ahlolwe abangela ukwakheka kwe-chemotaxis kanye ne-biofilm yohlobo lwe-SQY 162;Nokho, izinga lokukhula kwebhaktheriya alizange lithonywe ukwengezwa kwama-carbohydrate.Impendulo eqinile ye-chemotactic kanye nokwakheka kwe-biofilm ye-SQY 162 kokubili kudalwe i-pectin ngokukhuthazwa kwe-surfactin synthesis kanye nokuvezwa okubhaliwe kwezakhi zofuzo ze-matrix ezihlobene nokwakheka kwe-biofilm.Le miphumela iphakamise ukuthi i-pectin ingase isebenze njengesici semvelo ekukhuthazeni ukwakheka kwe-biofilm ye-SQY 162. Ngaphezu kwalokho, ekuhlolweni kwebhodwe ukukhiqizwa kwe-surfactin kanye ne-ion egcwele ye-SQY 162 ku-rhizosphere yanda kakhulu ngokungezwa kwe-sucrose noma i-pectin, kuyilapho ubuningi be-pathogen yebhaktheriya i-Ralstonia yehla.Ngokukhuphuka kokukhiqizwa kwama-metabolites esibili ku-rhizosphere kagwayi nge-SQY 162 kanye nokuminyana kwe-colonization okuthuthukisiwe kwe-SQY 162 ekwelapheni kwe-pectin, izehlakalo zezifo ze-bacterial wilt zacindezelwa ngokuphumelelayo.Ucwaningo lwamanje luveze ukuthi izitshalo ezithile ezikhishwe esitshalweni zingase zisebenze njengemithombo yamandla noma izinkomba zemvelo ze-SQY 162 ukuthuthukisa ukuminyana kwabantu ezimpandeni zikagwayi kanye nempumelelo yokulawula i-bio ye-wilt kagwayi yebhaktheriya.
