Ujeedada daraasaddan ayaa ahayd astaamaha hidda-socodka iyo qiimeynta badbaadada ee 129 Enterococcus go'doominta laga helay khamriga oo ku socda halsano malolactic ah.Astaamaha hidde-sidaha ee DNA-PCR si aan kala sooc lahayn loo xoojiyay ayaa muujiyay 23 genotypes.25 go'doomin wakiil dhammaan genotypes waxaa loo aqoonsaday sida Enterococcus faecium by noocyada PCR-gaar ah oo lagu qiimeeyay iska caabinta antibiyootiga, joogitaanka hiddo-wadaha fayraska iyo awoodda aminobiogenic, labadaba dhexdhexaadiyaha decarboxylase iyo khamriga.Awoodda aminobiogenic ee khamriga waxaa lagu falanqeeyay joogitaanka (qiimaynta 1) iyo maqnaanshaha (qiimaynta 2) ee Oenococcus oeni CECT 7621. Iska caabbinta tetracycline, cotrimoxazol, vancomycin iyo teicoplanin ayaa lagu soo bandhigay 96% noocyada, laakiin midkoodna ma qaadin baaritaanka. hiddo-wadeyaasha fayraska.Dhammaan noocyada kala duwan waxay haysteen hidda-wadaha tyrosine decarboxylase (tdc), halka 44% ay u wanaagsanaayeen tyramine ee dhexdhexaadka ah ee decarboxylase.Shantii nooc ee 25 ka mid ah ayaa khamriga ku badbaaday todobo maalmood oo ka mid ah ka dib markii la beeray, iyo markii la isku dayay ee amines-ka biogenic ee khamriga lagu go'aamiyay HPLC, kaliya kuwa khamriga ah ee shanta nooc ee badbaaday ay ku jiraan amines biogenic ah.Histamine, putrescine iyo cadaverine ayaa laga helay khamriga laga soo qaaday labada imtixaan, in kasta oo fiirsashada ay sare u kacday baaritaanka 2. Tyramine iyo phenylethylamine ayaa la ogaaday kaliya maqnaanshaha O. oeni.Cilmi-baaristu waxay gacan ka geysataa aqoonta dhinacyada amniga ee enterococci ee la xidhiidha khamriga.
