Comparative Studies on Production Technology of Pleurotus species and Shizophyllum species

Abstract

Oyster mushroom (Pleurotus spp.) is a member of the fungal sub-division Basidiomycotina. Split gills mushroom (Shizophyllum commune) belongs to the family of Shizophyllaceae of Agaricales. In India the oyster mushroom is known as 'Dhingri‟ and grows in temperate and tropical forests. The present investigation was carried out on the present investigation were carried out on “Comparative studies on production technology of Pleurotus species and Schizophyllum species” The colonies of Pleurotus sp. were observed as cottony/shiny/creamy white with circular dense or sparse margins. Colonies of Schizophyllum sp. were observed as pure white. Strain Sch-21-01 have dense fluffy while margins of Sch-21-03 and Sch-21-06 were sparse. The fruiting bodies of evaluated strains were found to be developed in clusters or rarely single. Fruiting bodies of Pl-21-04 and Pl-21-09 were observed fan like structure while fruiting bodies of PL-21-06 were umbrella like structure and quickly alter to a fan shape structure. The pileus of Pl-21-04 and PL-21-06 were creamy white in colour while, pileus of Pl-21-09 were dirty white in colour. Stipe of Pl-21-04 and Pl-21-09 were decurrent, stiff, hard, off white to pale white, and eccentric. While stipe of PL-21-06 was attenuated type, eccentric, occasionally central, and solid. Fruiting bodies of Schizophyllum species were scattered or clustered. The pileus was short and upper surface was covered with very small white hairs while margins were wavy. Among different media evaluated malt extract agar was found best for Pleurotus while in case of Schizophyllum sp. (Sch-21-06) Saubouraud dextrose agar was found best however, Czapek dox agar media was found least suitable. Among different chemical additives, PDA+MgSO4 @2% was found best while potato dextrose agar was found least suitable for Pleurotus sp and Schizophyllum sp. Among cereal flours tested, the maximum spawn growth was found in wheat grain + Maize flour @3% while in case of inorganic additives maximum spawn growth was observed in wheat grain + MgSo4 @2% in Pleurotus species (PL-21-09) as well as Schizophyllum species ( Sch-21-06). The maximum yield of both mushrooms (Pleurotus species (PL-21-09) and Schizophyllum species (Sch-21-06) were observed in wheat straw + rice flour@4% among the all cereal flour additives and in wheat straw + MgSo4 @2.5% among all chemical additives.
