Cultivo do cogumelo comestível Pleurotus ostreatus em bagaço de bocaiúva pela técnica Jun-Cao

Abstract

The adaptation of Pleurotus species to new residues is currently one of the main processes of bioconversion of agro-industrial residues in edible products of high nutritional value. The present work, using the principle of clean technologies, cultured/strain EF-136B lot of Pleurotus ostreatus in marc marc Bocaiúva supplemented with sugarcane bagasse. The biological efficiency (BE) obtained in Treatment 1 (T1 - composed of 70% sugarcane bagasse and 30% of Bocaiúva bagasse) was 30.81 ± 9.23 and in Treatment 2 (T2 - comprising 50% of sugarcane bagasse and 50% of Bocaiúva bagasse) was 37.51 ± 9.45, these were not statistically different for the confidence interval of 95%, however there is a perceived tendency to increase the EB with the greatest amount of Bocaiúva bagasse, probably because it presents higher C/N ratio of 55,80:1 against 49,48:1 for T1, confirming the literature that states that the C/N ratio must be greater than 29:1. The standardization of cultivation Bocaiúva bagasse allow a reasonable EB can be used as a substrate for future commercial crops.
