Shiitake cultivation in axenic blocks containing brewery residue

Abstract

Shiitake (Lentinula edodes) edible mushroom growth in an axenic block is the most popular method worldwide allowing higher productivity and a shorter cultivation cycle, than the conventional in wood logs. Blocks might be composed of residues from several agro-industrial activities. Among them, the brewery industry generates abundant waste that can cause negative environmental impacts if its incorrect disposal of in the environment, but it has not been studied to shiitake. The goal of this study was to evaluate if it is possible to produce it on barley malt bagasse (BMB) as one of the raw materials on the block. Results show shiitake biological efficiency (BE), productivity (PR), and their features. Substrates with C:N ratios of 30:1 and 36:1 resulted in BE values of 20.18 and 16.41% and PR of 10.91 and 10.19% showing that it is possible to product shiitake on blocks containing BMB.
