Abstract
Pectinolytic yeasts,
Saccharomyces marxianus, S. bayanus, S. cerevisiae
var.
ellipsoideus
, and
Schizosaccharomyces
sp., predominated in the natural fermentation of coffee cherries of
Coffea robusta
variety grown in Chikmagalur district of Mysore State, India. These yeast species were found on the cherry surfaces, and evidence was adduced to show that the natural fermentation of coffee was the result of activity of microflora from the cherry surface itself rather than that of flora of air or water. Incorporation of pure cultures of
Saccharomyces
species was shown to aid the process when a mixture of all three species was used. An enzyme preparation from the
Saccharomyces
species was observed to hasten the mucilage-layer degradation.
