Biological efficiency and protein content of Pleurotus florida cultivated on waste cellulosic substrates

Pleurotus florida is an industrially cultivated basidiomycete with nutritional، environmental and medical properties. In This study used the cellulytic waste materials contains newspaper، straw paper، inkjet printed paper، laser printed paper، handwritten paper، plain paper. The effects of different substrate on fruit body formation، biological efficiency and protein content of P. florida in 50 days period were examined. Spawn running، pin head and fruit body formation، were studied and the results demonstrated that these three phases take less time in straw paper treatment compare to control. In the all treatments، protein content were decreased. The most protein content was observed in the laser printed paper while the lowest measure of protein content showed in the straw paper treatment. The waste paper treatments decreased biological efficiency and also in the protein content of P. florida.
