Popularly known as pupunha, Bactris gasipaes Kunth is a palm tree native to the Amazon region whose planting has extended to the Southern and Southeastern states of Brazil. The production and consumption of peach palm generate a huge volume of by-products. It is estimated that approximately 84% of the total weight of the palm are lignocellulosic wastes. The white-rot fungus Pleurotus ostreatus was used for biological pretreatment of peach palm lignocellulosic wastes (inner sheath and peel) for improving the enzymatic saccharification and production of glucose. Non-treated and pre-treated B. gasipaes inner sheath and peel were submitted to hydrolysis by a commercial cellulase preparation from T. reesei. The amounts of total reducing sugars and glucose obtained from the 30d-pretreated inner sheath were seven and five times superior, respectively, when compared to those obtained with the non-pretreated inner sheath. However, the pre-treatment did not cause any improvement in the saccharification of the B. gasipaes peel. Scanning electronic microscopy of lignocellulosic fibers was done to verify the structural changes caused by the biological pretreatments. Upon the biological pretreatment the lignocellulosic structures of the inner sheath were substantially modified to less ordered ones. The main features of the modifications were detachment of the fibers, cell wall collapse and, in several cases, formation of pores in the cell wall surfaces. The peel lignocellulosic fibers showed more ordered fibrils and no modification was observed after pre-treatment. In conclusion, P. ostreatus pretreatment considerably improved saccharification of the B. gasipaes inner sheath (7-fold), but ´pretreatment of the peel was largely ineffective.
