Avaliação da eficiência biológica e produtiva, de substrato a base de bambu Dendrocalamus asper, para a produção de Pleurotus ostreatus e Pleurotus sajor-caju

Abstract

The demand for a healthier diet has been growing all over the world. Even as we are going through an intense crisis, the population seeks to adhere to a healthier lifestyle, consuming less industrialized products that fit their budget. Mushroom cultivation has been emerging as an alternative to natural protein rich foods with many benefits. Growers are always looking to cheapen their cultivation, with research of low-cost alternative substrates, bamboos can be an alternative in effective production due to their composition and low cost. The objective of this work was to evaluate the potential of using bamboo as substrate for the production of mushrooms of the species Pleurotus sajor-caju and Pleurotus ostreatus, supplemented with wheat bran and limestone, was compared with a conventional sawdust-based substrate. determination of biological and productive efficiency. The experiment was carried out at the Wood Technology Laboratory of the Federal Technological University of Paraná-Campus DoisVizinhos. Two treatments were elaborated for each species: T1: supplemented sawdust; and T2: supplemented bamboo; Twenty replicates of each species were prepared for each treatment.Both substrates were saturated with moisture, packed in polypropylene bags with a capacity of 1 kg in 500 gram aliquots and autoclaved for complete sterilization of the material for 40 minutes, at 121 ° C. Inoculated substrates were incubated for myceliation and frutification. The outcome measures of each treatment were compared by ANOVA and Tukey post-test. The biological efficiency results of both species in the bamboo-based substrate were higher than in the conventional substrate, demonstrating the potential of bamboo as a substrate for mushroom cultivation.
