Abstract
The present work is aimed to show the effects of cdmium in the growth of two bacteria species in the presence of naphthalene solubililzed in ethanol The Pseudomonas pulida culture and I 16, isolated from gasoline soil contaminated with ability to biosurfactant production, were able to growth in naphthalene ethanol until 20 ppm concentration. When a cadmium solution was added of this naphthalene medium we detected a largest bacterial growth with 0.18 ppm of cadmium. We also detected um adaptation period in the growth on the I.8 and 18 ppm of the metal once the final protein concentrations was almost the same in all experimental conditions.
