Injongo yolu phononongo ibiluphawu lwemfuzo kunye novavanyo lokhuseleko lwe-Enterococcus isolate ezili-129 ezifunyenwe kwiwayini evundiswa yimalolactic.Ukubonakaliswa kwe-Genetic nge-polymorphic DNA-PCR eyenziwe ngokungakhethiyo ibonise i-23 genotypes.Ii-25 ezizimeleyo ezimele zonke i-genotypes zachongwa njenge-Enterococcus faecium nge-PCR yohlobo oluthile kwaye zavavanyelwa ukuxhathisa amayeza okubulala iintsholongwane, ubukho bejene yentsholongwane kunye nomthamo we-aminobiogenic, zombini kwi-decarboxylase medium kunye newayini.Umthamo we-aminobiogenic kwiwayini uhlalutywe kubukho (i-assay 1) kunye nokungabikho (i-assay 2) ye-Oenococcus oeni CECT 7621. Ukumelana ne-tetracycline, i-cotrimoxazol, i-vancomycin kunye ne-teicoplanin ibonakaliswe yi-96% yeentlobo, kodwa akukho namnye kubo oye waba ne-assaye imfuza yentsholongwane.Zonke iintlobo ziphethe i-tyrosine decarboxylase (tdc) gene, ngelixa i-44% yayilungile kwi-tyramine kwi-decarboxylase medium.Zintlanu kuphela kwiintlobo ezingama-25 eziye zasinda kwiwayini emva kweentsuku ezisixhenxe zokufukanyelwa, kwaye xa i-concentrations ye-biogenic amines kwiwayini yamiselwa yi-HPLC, zezo wayini kuphela apho ezi ntlobo zintlanu ziseleyo zenzeka khona zazine-biogenic amines.I-histamine, i-purescine kunye ne-cadaverine zifunyenwe kwiiwayini ezivela kuzo zombini ii-assay, nangona ugxininiso lwaluphezulu kwi-assay 2. I-Tyramine kunye ne-phenylethylamine zifunyenwe kuphela xa ingekho i-Oeni.Olu phando lunegalelo kulwazi lwemiba yokhuseleko lwe-enterococci enxulumene nokwenza iwayini.
