Obtenção de linhagens de Lentinula edodes resistentes a temperaturas elevadas e seleção de linhagens resistentes ao Trichoderma sp

Abstract

Lentinula edodes (Berk.) Pegler (shiitake) is the second most consumed mushroom in the world and its production can be made in natural logs or in axenic culture using agroindustrial residues as substrate. The cultivation of shiitake in Brazil has been seriously harmed by the high incidence of contaminant fungi such as Trichoderma sp. and by the absence of strains adapted to tropical temperatures. Two strains resistant to Trichoderma sp. were obtained by selection when grown in contact with the contaminant fungus and, by mycelial fragmentation, strains were obtained that can resist high temperatures and grow at 30º C in a culture medium.
