The effect of substrate composition on bioprocess feasibilitywas assessed for the different strains by quantitative (i.e., mushroom yield and Biological Efficiency-BE %) andcarposome qualitative parameters (i.e., weight, size, colour, firmness). P. ostreatus strains produced carposomesearlier than P. eryngii ones. Early fruiting formation was promoted in WS for P. ostreatus strains, whereas forP. eryngii the lowest values of earliness were observed on BOS substrate. As for crop productivity, P. ostreatusstrain AMRL 150 provided the highest BE (>70%) in all substrates except for RB, while P. ostreatus strain AMRL144 achieved the highest yield and BE in BOS and BWS (75.30 and 64.26%, respectively). P. eryngii stainsproduced less number but heavier carposomes. The highest values of BE% for these strains were recorded on WSand BOS substrates. The BE was further correlated to growth parameters of fungal vegetative phase. As formushroom colour, P. ostreatus were lighter than P. eryngii and BOS substrate promoted lightness in both strains.Firmer P. ostreatus mushrooms were produced at CR. No differences in the whiteness and firmness were detectedamong P. eryngii mushrooms and at any substrate used. The data included in this paper showed that Pleurotusmushrooms can be cultivated on low- or zero-value agro-industrial residues of great financial and environmentalimportance towards the production of value-added food products.展开更多
