abstract={The yeasts involved in cocoa fermentation play an important role in obtaining good cocoa beansˇŻ quality. Apart from cocoa fermentation, these yeasts could have a good inhibitory action against the growth of any phytopathogenic microorganism notably <i>Dickeya</i><i> </i><i>dqdantii</i> and <i>Dickeya</i><i> </i><i>solani.</i><i> </i>This study is the first to evaluate the inhibitory action of yeasts involved in cocoa fermentation on the rot potato phytopathogen. For this purpose, the yeasts isolated from C?te dˇŻIvoire were confronted with the sensitive strain of <i>Saccharomyces</i><i> </i><i>cerevisiae</i> (W303). Moreover, the yeast killers were used to evaluate their inhibitory action on <i>Dickeya</i><i> </i><i>solani</i> and <i>Dickeya</i><i> </i><i>dadantii</i>. Finally, the physicochemical parameters (temperature, pH and salt concentration) capable to influence the inhibitory action of killer yeasts on <i>Dickeya</i><i> </i><i>solani</i> and <i>Dickeya</i><i> </i>were evaluated. Thirty-three (33) yeasts out of the yeasts isolates tested were capable to produce toxic substances against the sensitive strain of <i>Saccharomyces</i><i> </i><i>cerevisiae</i> (W303). Among these yeasts, 14 are capable to inhibit the growth of <i>Dickeya</i><i> </i><i>solani</i><i> </i>at temperature of 25 ˇăC and 30 ˇăC as well as pH of 4.5 and 6. Four (4) of these yeasts (C1P8, E10P10, D12P12 and E10P19) exert an inhibiting action on the growth of <i>Dickeya</i><i> </i><i>dadantii</i> in the same condition as before. These four yeasts isolates can be used in the biological fight against these two phytopathogens responsible for potato rot.},
