Conteúdo:	Pseudomonas may use as bioremediator and as biopesticide. The use of soil enzymatic assays as biological indicator of possible negative effects in soil functioning was evaluated after P.putida AF7 inoculation. For that, AF7 was originally isolated from the rizosphere of rice and was inoculated on three soils: Rhodic Hapludox (RH), Typic Hapludox (TH); and Arenic Hapludult (AH). Soil characteristics were measured in each plot. Acid phosphatase, ?-glucosidase and protease activities were measured at 7, 14 and 21 days. The enzyme activity waved during the experimental period but there is a significant reduction of ?-glucosidase activity in RH soil on day 14. Corg was positively correlated to the activities of ?-glucosidase and protease. The presented data indicate that soil biochemical properties may be useful as indicator of soil perturbations.
