LOPEZ-RODRIGUEZ, Claudia; HERNANDEZ-CORREDOR, Ricardo; SUAREZ-FRANCO, Christian  e  BORRERO, Marta. Evaluation of growth and production of Pleurotus ostreatus on different agroindustrials wastes of Cundinamarca. Univ. Sci. [online]. 2008, vol.13, n.2, pp.128-137. ISSN 0122-7483.

The culture of Pleurotus ostreatus was evaluated to determine the best waste on which this mushroom can show the highest growth and production rates.. The substrates evaluated were agroindustrial wastes of the Department of Cundinamarca (dry skin of goldenberries (Physalis), skin of pea pods and maize cobs). The control substrate was sawdust of oak. The mixtures evaluated were packed in bags of 1 kg containing 78 % of agroindustrial waste of the volume of substrate mixture . Mixtures were sterilized and inoculated with 30 g of seeds of Pleurotus ostreatus obtained commercially. Running time of the mycelium, diameter of fruit bodies, number of fruit bodies produced per bag, fresh weight, biological efficiency, and yield were evaluated on each of the substrates. Finally, the best substrate for the growth and production of Pleurotus ostreatus was the dry skin of goldenberries (Physalis) with a biological efficiency of 76.1% after a total production period of 41 days and a yield of 39.03 Kg/m² with excellent organoleptic characteristics, therefore being an adequate and efficient substrate for cultivating this mushroom.
