Bacillus amyloliquefaciens ibhakitiriya rinobatsira chirimwa cheGram-positive rinobatanidzwa mukudzvanya utachiona hunotakurwa nevhu kuburikidza nekuvanzika kwemasecondary metabolites uye kugona kwepamusoro kwerhizosphere.Kuumbwa kweBiofilm kunoonekwa sechinhu chinodiwa kune yakakwira rhizosphere kugona.Mune basa iri, tinoratidza kuti mashizha emiti anokanganisa chemotaxis uye biofilm kuumbwa kweB. amyloliquefaciens SQY 162 (SQY 162).Yese macarbohydrates akaedzwa akakonzera chemotaxis uye biofilm kuumbwa kweSQY 162 strain;zvisinei, chiyero chekukura kwebhakitiriya chakanga chisina kukanganiswa nekuwedzera kwemakhahydrates.Mhinduro yakasimba ye chemotactic uye biofilm kuumbwa kweSQY 162 zvose zvakakonzerwa nepectin kuburikidza nekukurudzira surfactin synthesis uye transcriptional kutaura kwebiofilm formation inoenderana nematrix majini.Migumisiro iyi yakaratidza kuti pectin inogona kushanda sechinhu chezvakatipoteredza mukukurudzira kuumbwa kwebiofilm yeSQY 162. Uyezve, mukuedza kwepoto kugadzirwa kwesurfactin uye ion yehuwandu yeSQY 162 mu rhizosphere yakawedzera zvakanyanya nekuwedzera kwe sucrose kana pectin, nepo kuwanda kwebhakitiriya pathogen Ralstonia yakaderera.Nekuwedzera kwekugadzirwa kwechipiri metabolites mu rhizosphere yefodya neSQY 162 uye yakagadziridzwa colonization density yeSQY 162 mukurapa kwepectin, chiitiko chechirwere chebhakitiriya wilt chakanyatso kudzvinyirirwa.Chidzidzo chazvino chakaratidza kuti zvimwe zvinomera zvinomera zvinogona kushanda semasimba emagetsi kana matipi ezvemamiriro ekunze eSQY 162 kuwedzera kuwanda kwehuwandu pamidzi yefodya uye kushanda kwebio-control yefodya bacterial wilt.
