Abstract
ObjectiveTo isolate and characterize the alcohol-producing yeasts from Woodfordia fruticosa flowers, which are used for the induction and maintenance of fermentation in the making of Ayurvedic formulations. Materials and methodsInitially twenty four yeasts strains were isolated on MGYP agar plate. Among them, four strains were selected for further studies on the basis of their alcohol generation capacity using jaggery media (50% w/v). Physiological, biochemical and genetic characterization (18S rRNA sequencing) of selected strains were carried out. ResultsPhysiological, biochemical and genetic characterization (18S rRNA sequencing) confirmed the strains as Saccharomycopsis fibuligera Jm.8, S. fibuligera Jm.10, S. fibuligera Jm.16 and Saccharomyces cerevisiae Jm.20. Under the controlled conditions, S. cerevisiae Jm.20 produced 69.57 g/l of alcohol, whereas remaining strains produced the alcohol in the range of 6.04–7.32 g/l. ConclusionAmong selected strains, strains S. fibuligera are a newer in the flowers. Kinetic study of alcohol generation revealed the strain S. cerevisiae Jm.20 can be efficiently used in making of fermented Ayurvedic formulations instead of use W. fruticosa flowers.
