In addition, the digestate derived from the anaerobic digestion of a mixture of these AIW was also evaluated to cultivate this fungus. The mycelial vigor of <em>Lentinula edodes</em> was evaluated during in vitro cultivation, seed production and cultivation at the substrate level prepared from AIW. Physical characteristics, growth and physicochemical analysis of the cultivated fungus and a sensory analysis of basidiomas were performed. The highest mycelial vigor was obtained in PDA culture medium, at pH 7.0, AIW extract, incubation at 20 °C and spore inoculum in liquid consistency. Anaerobic digestate produced basidiomas with higher pH, protein, mineral and moisture content (6.7 ± 0.1; 20.7 ± 0.1 %; 4.5 ± 0.3 %; 86.9 ± 0.6 %, respectively), when compared to the trial without anaerobic digestate.
