We evaluated the influence of yeast biomass and mannoproteins in the biodegradation and retention of biodiesel in soil. After 60 days of experiments, the biomass reached a biodegradation of 81%, a considerably higher value than reached through natural attenuation (3.6%). The adsorption of contaminants was 20%, indicating interactions between soil and biostimulants.
