The cultivation of mushrooms generates large amounts of waste polypropylene bags stuffed with wood flour and bacterial nutrients that makes the mushroom waste (MW) a potential feedstock for anaerobic bioH fermentation. MW indigenous bacteria were enriched using thermophilic temperature (55°C) for use as the seed inoculum without any external seeding. The peak hydrogen production rate (6.84 mmol H/L-d) was obtained with cultivation pH 8 and substrate concentration of 60 g MW/L in batch fermentation. Hydrogen production yield (HY) is pH and substrate concentration dependent with an HY decline occurring at pH and substrate concentration increasing from pH 8 to 10 and 60 to 80 g MW/L, respectively. The fermentation bioH production from MW is in an acetate-type metabolic path.
蘑菇栽培会产生大量装满木粉和细菌营养物质的废弃聚丙烯袋，这使得蘑菇废料（MW）成为厌氧生物制氢发酵的潜在原料。利用嗜热温度（55°C）富集MW中的本土细菌，用作种子接种物，无需任何外部接种。在分批发酵中，培养pH值为8且底物浓度为60 g MW/L时，获得了最高产氢率（6.84 mmol H/L-d）。产氢量（HY）取决于pH值和底物浓度，当pH值从8增加到10以及底物浓度从60 g MW/L增加到80 g MW/L时，HY分别下降。MW发酵生物制氢遵循乙酸型代谢途径。
