Direct utilization of peach wastes for enhancements of lignocellulolytic enzymes productions by Pleurotus eryngii under solid-state fermentation conditions

One of the main wastes that created environmental troubles is lignocellulosics such as fruit pulps collected in huge amounts from food industry. Peach wastes were utilized as the substrates raise ligninocellulolytic enzymes productions, namely manganese peroxidase (MnP), lignin peroxidase (LiP), carboxymethyl cellulase (CmCase), xylanase, exoglucanase, beta-glucosidase (BGLA), by Pleurotus eryngii. The effects of different concentrations with different compounds, copper, iron, Tween 80, ammonium nitrate and manganese on productions of ligninocellulolytic enzymes were investigated contingent on incubation time. The optimal productions of ligninocellulolytic enzymes were attained by 5.0 g peach waste and 70 mu M Cu2+, 18 mu M Fe2+, 4.0 gL(-1) ammonium nitrate, 250 mu M Mn2+, 0.025% (v/v) Tween 80 qua the inductivers. According to the results under optimized conditions, 6.51-, 9.52-, 1.86-, 3.17-, 1.06-, and 2.73-fold boosts were achieved for lignocellulolytic enzyme activities of MnP, LiP, CMCase, Xylanase, exoglucanase, BGLA, respectively. This study is important with regard to succeed the improvement of six-lignocellulolytic enzymes activities utilizing various inducers. [GRAPHICS] .
