Özet
<p>The aim of the study is to investigate the effect of supplementation of growing media with different levels of <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/biogas" rel="noopener noreferrer" target="_blank">biogas</a> liquid waste (BLW) on the production of two commercial strains of shiitake (LE-Agroma and LE-Homegreen). The strains were cultivated on <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/quercus" rel="noopener noreferrer" target="_blank">oak</a> sawdust (OS) soaked with water containing 0, 2.5, 5, and 10% percentages of BLW and the effect of different treatments was evaluated for cultivation cycle, yield, biological efficiency, nutritional content, macro- <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/microelement" rel="noopener noreferrer" target="_blank">micro element</a> contents and accumulation of <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/heavy-metal" rel="noopener noreferrer" target="_blank">heavy metals</a> in the <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/fruiting-body" rel="noopener noreferrer" target="_blank">fruiting body</a>. The shortest cultivation cycle for shiitake mushrooms, i.e., 82.3 and 75.6 days, was obtained with 10% <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/wastewater-treatment" rel="noopener noreferrer" target="_blank">BLW treatment</a> in LE-Agroma and LE-Homegreen, respectively. The strains displayed the highest yield and BE (297.82 g kg−1–87.6% and 225.89 g kg−1–75.8%, respectively) in the same treatments. The use of BLW positively affected the fat, carbohydrate, macro and <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/microelement" rel="noopener noreferrer" target="_blank">micro element</a> contents of shiitake strains, whereas its increased supplementation inversely affected the protein content of the <a href="https://www.sciencedirect.com/topics/agricultural-and-biological-sciences/fruiting-body" rel="noopener noreferrer" target="_blank">fruiting body</a>. Accordingly, the left-over BLW after biogas production can be successfully used as an additive to cultivate shiitake mushrooms, with no risk to human health.</p>
