| Abstract: |
Killer yeasts from flowers of
Indian medicinal plants were isolated and the effect of their killer toxin was
determined on sensitive yeast cells as well as fungal pathogens. The toxin of Saccharomyces cerevisiae and Pichia kluyveri inhibited Dekkera anomala accumulating methylene
blue cells on Yeast Extract Peptone Dextrose agar (pH 4.2) at 21°C. There was no inhibition of growth or competition
between the yeast cells in the mixed population of S. cerevisiae isolated from Acalypha
indica. S. cerevisiae and P. kluyveri were found to tolerate 50%
and 40% glucose, while D. anomala
tolerated 40% glucose. Both S. cerevisiae
and P. kluyveri did not inhibit the
growth of Aspergillus niger, Candida albicans and Fusarium spp.
