以沼气发酵的废弃物---沼渣为试验材料,白黄侧耳(Pleurotus cornucopiae)2026为供试菌株,研究不同比例沼渣和玉米芯培养料中白黄侧耳的生长情况。试验结果表明：在供试配比范围内,随着沼渣添加量的增加,白黄侧耳菌丝生长速度呈增加的趋势；子实体产量呈现先增加后降低的趋势。其中试验配方3(40%沼渣,40%玉米芯,13%麸皮,5%玉米粉,2%石膏,含水量60%)用于栽培白黄侧耳,菌丝生长速度快,产量(每袋278.27 g)和生物转化率(69.57%)较高,并且子实体中镉、汞、铅、砷的含量远低于国家对食用菌中重金属含量的要求。

Biogas production residue (BPR)was prepared from cow house bedding (consisting of rice straw spread to 70-80 cm thickness in winter and 50 cm during other seasons,and covered with sawdust to a thickness of 15-20 cm)by adding 8%-9% water after 5-7 days,allowing fermentation to proceed at 35 ℃ for 20 days to produce biogas,and separating the residue from the fermentation liquor using a solid-liquid separator.The effects of replacing the sawdust and corn cob components of a substrate used for cultivating Pleurotus cornucopiae with different amounts of BGR (moisture content ~40%)on mycelial growth and mushroom fruit body yields was then determined.High mycelial growth rates (0.49 cm/d),fruit body yields (278.3 g per bag)and biological efficiency values (69.6%)were achieved following cultivation on a substrate consisting of 40% biogas residue,40% corn cobs,13% wheat bran,5% corn powder and 2% gypsum. Germanium,mercury,cadmium and selenium levels in the cultivated fruit bodies were below the allowable upper limits of heavy metal contamination set by the national food safety standards.
