Growth of different strains of Pleurotus ostreatus in lignocellulosic biomasses
Concilium(2022)
Abstract
Agro-industrial waste has been widely applied in bioprocesses, among which fungiculture has been highlighted for its ability to transform waste into value-added products. Thus, this study observed two strains (474 and 572) of Pleurotus ostreatus when cultivated in residues of pineapple crown, açaí seeds and mixture of pineapple crowns and açaí seeds, and evaluated the colonization of the substrates, formation of structures and quantity of mushrooms produced. In all the substrates, it was possible to observe complete colonization, with the emergence of primordia up to 20 days. In the treatments with the 474 strain, only in the pineapple crown substrate were there three flushes of production, while in the açaí seeds and pineapple crowns and açaí seeds, there were only two flushes. As for strain 542, all treatments showed three flushes. The pineapple crown substrate provided greater production of basidiocarps (fresh mass) in strains 474 and 542. Therefore, the capacity of adaptation and development of P. ostreatus strains in different substrates was evidenced, since mushrooms were produced with characteristics similar to those reported in the literature.
