Peach and Cherry Agroindustrial Wastes: New and Economic Sources for the Production of Lignocellulolytic Enzymes

Abstract


Pleurotus eryngii was incubated on both peach and cherry agroindustrial wastes by solid state fermentation for 30 days without/with pretreatment conditions. The lignocellulosic substrates were pretreated with dilute acid and alkaline solutions, hot water before incubation. The maximum carboxymethyl cellulase and xylanase activities peaked on 3rd and 5th days under control conditions of both wastes, respectively. The highest laccase and manganese peroxidase activities reached to their maximum on 17th day as 2193.06±50.4 UL-1 and 732.73±19.8 UL-1, respectively. The highest aryl alcohol oxidase activity was obtained as 239.25±7.3 UL-1 in control condition of peach cultures. The used pretreatment methods had generally negative effects on lignocellulolytic enzyme production. The highest lignocellulolytic activities were detected using peach wastes. To results, these wastes could be used as alternative, new and economic energy sources to produce high amounts of lignocellulolytic enzymes.
