Bacillus amyloliquefaciens bụ ihe ọkụkụ na-erite uru nke Gram-positive bacteria na-etinye aka n'igbochi nje ndị na-ebute ala site na nzuzo nke metabolites nke abụọ na ikike rhizosphere dị elu.A na-ahụta nhazi biofilm dị ka ihe dị mkpa maka ikike rhizosphere dị elu.N'ime ọrụ a, anyị na-egosi na ihe ọkụkụ na-emetụta chemotaxis na biofilm nhazi nke B. amyloliquefaciens SQY 162 (SQY 162).Ndị carbohydrates niile nwalere kpalitere chemotaxis na biofilm nke ụdị SQY 162;Otú ọ dị, mmụba nke carbohydrates emetụtaghị mmụba nke nje bacteria.Nzaghachi chemotactic siri ike na nhazi biofilm nke SQY 162 bụ nke pectin kpalitere site na mkpali nke njikọ surfactin na nkwupụta ederede nke mkpụrụ ndụ ihe nketa biofilm metụtara matrix.Nsonaazụ ndị a na-atụ aro na pectin nwere ike ịbụ ihe na-eme gburugburu ebe obibi na mkpali nke biofilm guzobe nke SQY 162. Ọzọkwa, na ite nnwale mmepụta surfactin na populat ion nke SQY 162 na rhizosphere budata ụba na mgbakwunye nke sucrose ma ọ bụ pectin. ebe ịba ụba nke nje pathogen Ralstonia belatara.Site na mmụba nke mmepụta metabolites nke abụọ na rhizosphere nke ụtaba site na SQY 162 yana njupụta njupụta nke SQY 162 ka mma na ọgwụgwọ pectin, a na-ebelata ọrịa nke wilt nje nke ọma.Ọmụmụ ihe dị ugbu a kpughere na ụfọdụ mịpụta ihe ọkụkụ nwere ike bụrụ isi mmalite ike ma ọ bụ akara gburugburu ebe obibi maka SQY 162 iji kwalite njupụta ọnụ ọgụgụ mmadụ na mgbọrọgwụ ụtaba yana njikwa bio-nkwarụ nke nje nje ụtaba.
