Tea waste (TW) was investigated as a new supplement for substrate mixtures in Ganoderma lucidum cultivation. The effects of sawdust (S) based substrates supplemented with TW at the various levels (75S:25TW, 80S:20TW, 85S:15TW, and 90S:10TW) and Ganoderma lucidum strains on yield, biological efficiency (BE) and the chemical composition of fruiting bodies were determined in solid-state fermentation. Significant differences were found among substrates regarding yield and BE, while yield and BE of the strains were not different. The substrate formulations producing highest yield and BE were 80S:20TW (87.98 g/kg substrate and 34.90 % ) and 75S:25TW (82.30 g/kg substrate and 31 % ). Yield and BE of substrates containing TW were generally higher than that of the control (80sawdust:18wheat bran:1sucrose:1 CaCO3). Nitrogen, potassium, iron, and manganese contents and C:N ratios of substrates were strongly correlated with yield. BE showed positive and significant correlations with potassium, iron and manganese. Moisture content, potassium, magnesium, calcium, iron, and zinc contents of the fruiting bodies were affected by both strain and substrate. It was concluded that TW can be used as a supplement for substrate preparation in G. lucidum cultivation.
