The present work is aimed to show thé effects of cadmium in thé growth oftwo bacteria species in the presenceof'llilplltlalele solubilized in ethanol. The Pseudomonas putida culture and 116, 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 ofthis naphthaiene médium we detected a largest bacterial growth with 0.18 ppm of cadmium. We also detected um adaptation period in the growth on the 1.8 and 18 ppm oftthe metal once the final protein concentrations was almost the same in all cxperimental conditions.
