Isolation and screening of yeasts for navel orange wine

The yeasts used for navel orange wine fermentation were isolated and screened from the naturally fermented navel orange wine and the soil in navel orange orchard.The fermentation performances of these yeasts were compared with that of standard yeast strain,by which the excellent yeast for navel orange wine was selected.The results showed that 26 yeast strains were isolated and the strain named GJ-4 exhibited good fermentation properties.GJ-4 could induce fermentation quickly with a low fermentation rate and enhance aromas.
