ʻO ka pahuhopu o kēia noiʻi ʻana, ʻo ia ke ʻano genetic a me ka loiloi palekana o 129 Enterococcus isolates i loaʻa mai ka waina i ka hoʻoheheʻe malolactic.Hōʻike ʻia ke ʻano genetic e ka polymorphic DNA-PCR i hōʻike ʻia i 23 genotypes.Ua ʻike ʻia ʻo Enterococcus faecium he 25 mau mea hoʻokaʻawale i nā ʻano genotypes e ka PCR kikoʻī kikoʻī a hoʻāʻo ʻia no ka pale ʻana i ka lāʻau antibiotic, ka loaʻa ʻana o nā genes virulence a me ka mana aminobiogenic, ma ka medium decarboxylase a me ka waina.Ua nānā ʻia ka mana aminobiogenic i loko o ka waina i mua (assay 1) a me ka ʻole (assay 2) o Oenococcus oeni CECT 7621. ʻO ke kūʻē ʻana i ka tetracycline, cotrimoxazol, vancomycin a me teicoplanin i hōʻike ʻia e 96% o nā kānana, akā ʻaʻohe o lākou i hoʻopaʻa i ka assayed. nā genes virulence.Hoʻopaʻa ʻia nā ʻano a pau i ka gene tyrosine decarboxylase (tdc), aʻo 44% ka maikaʻi no tyramine i loko o ka medium decarboxylase.ʻElima wale nō o 25 mau kānana i ola i loko o ka waina ma hope o nā lā ʻehiku o ka hoʻomoe ʻana, a i ka wā i hoʻoholo ʻia ai ka nui o nā amine biogenic i loko o nā waina e HPLC, ʻo kēlā mau waina wale nō i loaʻa ai nā ʻano ʻelima e ola nei i loko o nā amine biogenic.ʻIke ʻia ka histamine, putrescine a me cadaverine i loko o nā waina mai nā hoʻāʻo ʻelua, ʻoiai ʻoi aku ka kiʻekiʻe o ka hoʻopaʻa ʻana ma ka hoʻāʻo 2. Ua ʻike ʻia ʻo Tyramine a me phenylethylamine i ka loaʻa ʻole o O. oeni.Hāʻawi kēia noiʻi no ka ʻike i nā ʻano palekana o ka enterococci e pili ana i ka hana waina.
