Title
The use of spent brewery grains for Pleurotus ostreatus cultivation and enzyme production
Abstract

In the brewing industry, spent brewery grains (SBGs) are byproducts with a low economic value. The potential use of this leftover as a substrate ingredient for Pleurotus ostreatus fruiting body cultivation and enzyme production was evaluated. The best substrate mixture for P. ostreatus mycelium growth comprised 30% wheat bran (WB), 68% beech sawdust (BS) and 2% CaCO3. On the substrates containing SBG, the fastest mycelium growth was observed on the substrate composed of 10% SBG, 20% WB, 68% BS and 2% CaCO3. The highest biological efficiency (51%) of fruiting bodies was determined on the mixtures containing 20% WB, 10% SBG and 2% CaCO3. The SBGs with the addition of WB were also shown to be suitable as a substrate for enzyme production. However, the supplementation levels designate which enzymes are produced and in what amounts.
