title: Evaluation of Burma Reed as Substrate for Production of Pleurotus eryngii.
abstract: Burma reed (Neyraudia reynaudiana), a giant C4 grass, was included in substrate at the rates of 0, 20, 40 and 66 % to partially or wholly substitute sawdust and cottonseed hulls to evaluate its suitability for Pleurotus eryngii cultivation. Inclusion of 20 and 40 % Burma reed did not significantly affect linear mycelial growth, dry matter loss, spawn run period and fructification, and achieved high fruiting body yields and biological efficiency of 336.67 g/bag, 67.33 % and 342.15 g/bag, 68.43 %, respectively, which were not significantly different from 350.08 g/bag to 70.02 % obtained from the control substrate. Enzyme assay revealed that on the mixed substrates laccase and manganese peroxidase activity were significantly enhanced, but cellulase was significantly reduced in the middle stage of incubation as compared with the control substrate. Even on Burma reed substrate without sawdust and cottonseed hulls, fruiting body yield (313.56 g/bag) and biological efficiency (62.71 %) were satisfactory, although significantly lower than that on the control substrate. Therefore, Burma reed was a promising potential substrate for P. eryngii production to largely substitute sawdust and cottonseed hulls.
