Two coating adhesives, 0.05 % Triton CS-7 and 0.1 % methylcellulose, on populations of microorganisms on corn kernels were tested by coating the kernels. There was non-significant difference on population densities of either bacteria or yeasts on surface of treated kernels at 14 days after coating, regardless of types of suspension and adhesives used. Twenty-nine and two isolates of bacteria that showed inhibitive and non-inhibitive (isolate 123, 158) actions, respectively against Aspergillus flavus in vitro and Lactobacillus plantarum TISTR543 were evaluated as biocontrol agents for treating corn kernels (26-27 % moisture content) in order to prevent infection and aflatoxin production by A. flavus. At 5 days after coating, all bacterial isolates could not significantly reduce the percentage of infected kernels (87.5-100 %) and population density of A. flavus on kernel surface (1.14*10** (5)-1.29*10** (6) cfu/kernel) as compared to the control (100 % and 7.43*10** (5) cfu/kernel). At the same period of storage, all seven isolates of yeasts satisfactorily inhibited the growth and infection of A. flavus while the lowest infection was found from the kernels treated with the yeasts isolates 4 (9.5 %). The lowest population density of A. flavus on kernel surface (1.09*10** (4) cfu/kernel) was detected from kernel treated with yeast isolate 6. Effective period for suppression of A. flavus on corn kernels with 26-27 % moisture content by yeasts was 15 days.
