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.
