Produção de Lentinula edodes em toras de híbridos de Eucalyptus grandis e Eucalyptus urophylla

The productivity of five strains of Lentinula edodes (LE-240, LE-241, LE-243, LE-244 and BP-245) is evaluated and their nutritional rates assessed and compared, totally or in parts, produced in wood from eucalyptus clone. The chemical composition of the wood before and after the culture cycle, mass and number of basidioma produced by the strains, protein rates of entire mushrooms, stipites and pillei were evaluated. Mean protein rates of entire mushrooms varied between 11.16 and 15.78%, with strains LE-240 and BP-245 featuring the highest rates. LE-241 had the best production performance, with the greatest production in basidium mass and greater decomposition of holocellulose rates. Current assay evidenced the importance of strain choice adapted to climatic conditions of the culture region. Strains may actually differ in productivity and nutritional quality.
