Iimveliso

I-Bacillus amyloliquefaciens yintsholongwane yeGram-positive eluncedo kwisityalo ebandakanyekayo ekucinezeleni iintsholongwane ezisasazwa ngumhlaba ngokukhuselwa kwesecondary metabolites kunye nobuchule obuphezulu berhizosphere.Ukuqulunqwa kwe-Biofilm kuthathwa njengento efunekayo kubuchule obuphezulu be-rhizosphere.Kulo msebenzi, sibonisa ukuba izicatshulwa zezityalo zichaphazela i-chemotaxis kunye nokwakheka kwe-biofilm ye-B. amyloliquefaciens SQY 162 (SQY 162).Zonke i-carbohydrates ezivavanyiweyo zenze ukuba i-chemotaxis kunye nokwakheka kwe-biofilm ye-SQY 162 strain;nangona kunjalo, izinga lokukhula kwebhaktheriya alizange liphenjelelwe kukongezwa kweecarbohydrates.Impendulo eyomeleleyo ye-chemotactic kunye nokwakhiwa kwe-biofilm ye-SQY 162 zombini zenziwe yi-pectin ngokuvuselela i-surfactin synthesis kunye nokubhaliweyo okubhaliweyo kwe-biofilm ukubunjwa kwejene ye-matrix ehambelanayo.Ezi ziphumo zicebise ukuba i-pectin inokusebenza njengento yokusingqongileyo ekukhuthazeni ukubunjwa kwe-biofilm ye-SQY 162. Ngaphezu koko, kwiimvavanyo zembiza ukuveliswa kwe-surfactin kunye ne-ion ye-populat ye-SQY 162 kwi-rhizosphere yanda kakhulu ngokudityaniswa kwe-sucrose okanye i-pectin, ngelixa ubuninzi bebhaktiriya pathogen iRalstonia yehla.Ngokunyuka kwemveliso ye-metabolites yesibini kwi-rhizosphere yecuba nge-SQY 162 kunye nokuphuculwa kwe-colonization density ye-SQY 162 kunyango lwe-pectin, iziganeko zesifo se-bacterial wilt zanyanzeliswa ngokufanelekileyo.Uphononongo lwangoku lubonise ukuba izicatshulwa ezithile zezityalo zinokusebenza njengemithombo yamandla okanye iimpawu zokusingqongileyo ze-SQY 162 ukomeleza ukuxinana kwabemi kwiingcambu zecuba kunye nolawulo olululo lwebhaktheriya yecuba.
