Abstract:
In the alternative energies perspective the major goal is to achieve safe, efficient, low-cost energy from the use of organic matter, microorganisms and waste, in order to use the carbohydrates, present in the biomass it is necessary to fraction and degrade the lignocellulosic structure through pretreatment. In this work, the potential of enzymatic production and fungal biomass of Pleurotus ostreatus (PO) is evaluated using peels of banana, dragon fruit (yellow), gulupa, mango, pineapple, and the whole goldenberry fruit. First, a mycelial growth rate (cm/day) was determined according to the visible diameter of the mycelium using a fruit-based agar. Then, in a semi-submerged culture biomass production, reducing sugars and enzymatic production (cellulases, pectinases, and laccases) was registered for 25 days at 27°C and 150 rpm. It was found that the fruit-based agars made of goldenberry, banana and dragon fruit were better promotors in mycelial growth of PO, in reducing sugars the behavior obtained varies from consumption and liberation, results from the production of laccase indicate that both pineapple and goldenberry cultures present high laccase activity and productivity, for the pectinases and cellulases activity it was obtained a decreasing profile of the enzymatic activity for the majority of fruit substrates. It is possible to conclude that, Pleurotus ostreatus is highly responsive to substrate composition due to the versatility of behavior obtained.
