Crescimento micelial de Pleurotus ostreatus em resíduo de Simarouba amara

Abstract

farelo de soja, a 25 e 30ºC. O melhor desenvolvimento de P. ostreatus ocorreu em meio malte-ágar 3% a 25ºC. A suplementação de farelo de soja na serragem de S. amara favorece o crescimento micelial.Termos para indexação: cogumelos comestíveis, cogumelo hiratake, crescimento micelial, serragem. Mycelial growth of Pleurotus ostreatus in Simarouba amara sawdustAbstract -The objective of this work was to assess the mycelial growth of oyster mushroom (Pleurotus ostreatus) cultivated in sawdust of Simarouba amara. Evaluations were made for the effect of temperatures 22, 25, 27, 30 and 35ºC on the mycelial growth of P. ostreatus in 3% malt-agar and SDA-MA (infusion of S. amara sawdust, enriched with soybean meal-dextrose-agar) media; and the mycelial growth in cultivation substrate of S. amara sawdust, with and without supplementation of soybean meal, at 25 and 30ºC. The best development of P. ostreatus was in 3% malt-agar medium at 25ºC. Soybean meal supplementation on S. amara sawdust promoted mycelial growth.

In vitro cultivation of Pleurotus ostreatus and Lentinula edodes in lignocellulosic residues from Amazon

“…The best result for L. edodes occurred for the substrate SIA-CA SUPL, which showed no statistical difference from the SIA-MA SUPL. It was also observed, in a general way, that the supplementation also favored the growing rate of the fungus in the substrate based on marupá (SAI-MA SUPL), as Sales-Campos et al (2008) evaluated when they analyzed the mycelial kinetic of P. ostreatus grown in S. amara sawdust to determine the optimal condition for the mycelial growth. Through the experiment, we verified that there was no growth in the substrates formulated with banana stalks, even with the supplementation of cereal brans.…”

“…The Pleurotus gender fungi compete with the other edible fungi due to their growth speed and ability to adapt to a series of sub-strates (Vieira et al, 2013), which happens because of an enzymatic complex composed of cellulases, ligninases, laccases, xylanases, peroxidases and hemicellulases (Elisashvili et al 2008). The behavior of the mycelial growth may vary according to a series of factors, such as the fungi species, genetic characteristics of the strain, temperature, type of substrate, supplementation, carbon/ nitrogen ratio, and others (Andrade et al, 2008;Sales-Campos et al, 2008). Several steps must be taken in the production of edible mushrooms from the obtention of the inoculum to the sale of the final product, as stated by Donini et al (2005).…”

Sawdust and fruit residues of Central Amazonian for Panus strigellus spawn’s production

“…Beer yeast and soybean extract presented lower IMGR values but also improved the colony vigor. Sales-Campos et al (2008) obtained the highest mycelial growth to Pleurotus ostreatus (Jacq.) P. Kumm.…”

Resíduos agroindustriais como substrato para cultivo indoor de cogumelos comestíveis da espécie Pleurotus ostreatus

“…A maioria dos cogumelos comestíveis originários de fungos apresentam índices relevantes de desenvolvimento micelial em diversos tipos de matéria-prima enriquecidos ou não com farelos de cereais (Eira, 2004;Sales-Campos et al, 2008). Geralmente os substratos utilizados para o cultivo de cogumelos são gramíneas secas, além de resíduos agrícolas como polpa de café, sabugo de milho e bagaço de cana de açúcar (Moda et al, 2005).…”
