Growth and sporophore yield in strain Pt-Omon13 of Pteurotus tuberregium (Fr.) Singer on substrates made of waste paper (WP), plantain peelings (PP), and different combinations of WP and PP was investigated. Sporophores were produced on all substrates and substrate combinations tested. A substrate combination containing 80% by weight of waste paper gave the highest sporophore yield, at 43.78 ± 5.1 (fresh weight) per 100 g. Another substrate combination containing 80 % by weight of plantain peelings gave the least sporophore yield among the substrate combinations tested (3.15 ± 0 g/100 g). The high Sporophores yield of this species on some of the substrate combinations may qualify WP and supplementation with PP as a suitable substrate for the low-cost mass production of this mushroom. This could also become an environmentally friendly avenue for biological recycling of these wastes, which are abundant in our immediate environment. The stability of the strain used (Pt-Omon13) as a selected "sporophore-only"-producing strain is further confirmed.
