Agarose gel electrophoresis of the PCR products obtained with the DNA extracted from toxic leaf litter.

The total DNA was extracted and purified from toxic leaf litter samples and the cry 4A, cry4B and cry11 genes were sought by PCR using the corresponding primers. The PCR products detected from toxic leaf litter (lanes 2 and 3) were compared to those obtained from the isolated bacterium serving as a control (lanes 4 and 5).
