Resumen:
The efficacy of two strains of Kluyveromyces thermotolerans in preventing the growth and ochratoxin A (OTA)accumulation of ochratoxigenic fungi both ?in vitro? and ?in situ? was evaluated. The data from this study showed that both yeast strains were able to control Aspergillus carbonarius and A. niger aggregate species growth and ochratoxin A accumulation. The inhibitory effects were dependent on the ochratoxigenic species,
yeast strains, aw and temperature evaluated and their interactions. Over all conditions assayed, ochratoxin A accumulation was reduced from 3% to 100% and the growth rate from 11% to 82.5%, depending on conditions.These results are promising for future development of a bio-pesticide.
