Inhloso yalolu cwaningo kwakuwukubonakaliswa kofuzo kanye nokuhlolwa kokuphepha kwama-Enterococcus isolate angu-129 atholwe ewayini elivutshelwa nge-malolactic.Ukulingiswa kofuzo nge-polymorphic DNA-PCR ethuthukisiwe ngokungahleliwe kubonisa ama-genotypes angu-23.Ama-isolate angama-25 amele zonke izinhlobo ze-genotype ahlonzwe njenge-Enterococcus faecium nge-PCR ethile yezinhlobo ezithile futhi avivinywa ukumelana nama-antibiotic, ukuba khona kwezakhi zofuzo ze-virulence namandla aminobiogenic, kokubili ku-decarboxylase medium kanye newayini.Amandla e-aminobiogenic ewayini ahlaziywa phambi (i-assay 1) kanye nokungabikho (i-assay 2) ye-Oenococcus oeni CECT 7621. Ukumelana ne-tetracycline, i-cotrimoxazol, i-vancomycin ne-teicoplanin kuboniswe ngama-96% wezinhlobo, kodwa akukho neyodwa yazo eyaba nemiphumela emibi. izakhi zofuzo.Zonke izinhlobo zazinofuzo lwe-tyrosine decarboxylase (tdc), kuyilapho u-44% wawuvuma i-tyramine ku-decarboxylase medium.Yizinhlanu kuphela kwezingu-25 izinhlobo ezasinda ewayinini ngemva kwezinsuku eziyisikhombisa zokufukamela, futhi lapho ama-concentration amine ama-biogenic amine ewayinini anqunywa yi-HPLC, yilawo mawayini kuphela lapho lezi zinhlobo ezinhlanu ezisaphila zenzeka ayequkethe ama-amine e-biogenic.I-histamine, i-purescine kanye ne-cadaverine zitholwe ewayinini kusuka kuzo zombili izivivinyo, nakuba ukugxila bekuphezulu ku-assay 2. I-Tyramine ne-phenylethylamine zitholwe kuphela uma ingekho i-O. oeni.Lolu cwaningo lunikela ngolwazi lwezingxenye zokuphepha ze-enterococci ezihlobene nokwenza iwayini.
