The objective of the present work was to evaluate the nutritional composition of mushrooms produced in alternative substrates in agricultural and agro-industrial residues from the Amazon. C, N, pH, moisture, soluble solids, protein, lipids, total fibers, ashes, carbohydrates and energy were determined. Substrates were formulated from Simarouba amara Aubl. and Ochroma piramidale Cav. ex. Lam. Sawdust and from Bactris gasipaes Kunth and Saccharum officinarum stipe. Results showed that the nutritional composition of P. ostreatus varied according to the cultivation substrate and that it can be considered important food due to its nutritional characteristics such as: high protein content; metabolizable carbohydrates and fiber; and low lipids and calories contents.
