Abstract:

The predominant yeast strain isolated from Lonicera edulis fruits after enrichment culture was tested for its acidresistant, alcohol-resistant, sulfurous acid-resistant and acid degrading properties. This was followed by fermentation of Lonicera edulis fruit wine with this strain after activation. It was found that this yeast strain could utilize citric acid and malic acid well and its ability to utilize tartaric acid was bad. Meanwhile, this yeast strain exhibited the resistance to sulfurous acid and alcohol. Moreover, fermentation with it resulted in a 13.2% decrease of acidity in Lonicera edulis fruit wine. Therefore, this strain will have promising application prospect in the fermentation of high-acidity fruit wine.

Key words: Lonicera edulis, yeast, fermentation characteristics, bio-deacidification, fruit wine
