| description | Fifteen yeast strains isolated from maprang (Bouea macrophylla Griffith) were characterised using standard microbiological
procedures. The species were identified belonging to three genera Saccharomyces, Hanseniaspora and Pichia and their abilities
for wine production were tested by analysing the alcohol produced and remaining sugar. The best biochemically active strain
was used along with commercial yeast (S. cerevisiae) to produce wine from maprang juice. Fermenting activity of isolated
yeasts was higher than commercial yeast. The isolated yeast strain namely 3.5B and 5.5A showed the best fermenting activity
such as fast fermentation by Durham test and highest alcohol percentage (11.5 and 11.83% v/v). Based on the 28S rRNA
sequences, yeast strain 5.5A and 3.5B showed 99% similarity to S. cerevisiae (KP723678.1 and KF728774.1, respectively).
Using isolated yeast strain 5.5A for wine fermentation at pH 4.0, total soluble solid content 24% and inoculated with yeast
density of 107 cells/mL, the alcohol content produced was 14.5% v/v and the wine had favorable color and flavor. Our work
constitutes a foundation for strain selection for future applications as starter cultures in fruit wine fermentations. This work is
the first ever on yeast diversity from maprang which is the special fruit of Vinh Long province, Vietnam. |
