Ensilage and fungal pretreatment of giant reed harvested from August through December were compared based on their effects on feedstock preservation, glucose yield, and subsequent methane production via anaerobic digestion (AD). Compared to fungal pretreatment, ensilage obtained lower total solids (<1.2%) and cellulose (<3.5%) losses, and comparable hemicellulose degradation, except for giant reed harvested in August. Ensilage increased glucose and methane yields by 7-15% and 4-14%, respectively, for giant reed harvested from August through December. Fungal pretreatment failed for giant reed harvested in August and October with reduced glucose yields, and was effective for that harvested in November and December, with about 20% increases in glucose yield. However, hydrocarbon losses during fungal pretreatment offset the increased glucose yield, resulting in decreased methane yields by AD. In summary, ensilage was found to be more suitable than fungal pretreatment for giant reed storage and its methane production via AD.
青贮和真菌预处理对 8 月至 12 月收获的巨蔺的影响进行了比较，主要是基于对原料保存、葡萄糖产量和后续沼气发酵（AD）的影响。与真菌预处理相比，青贮获得了较低的总固体（<1.2%）和纤维素（<3.5%）损失，以及可比的半纤维素降解，除了 8 月收获的巨蔺。青贮使 8 月至 12 月收获的巨蔺的葡萄糖和甲烷产量分别提高了 7-15%和 4-14%。真菌预处理对 8 月和 10 月收获的巨蔺无效，葡萄糖产量降低，而对 11 月和 12 月收获的巨蔺有效，葡萄糖产量增加约 20%。然而，真菌预处理过程中的碳氢化合物损失抵消了葡萄糖产量的增加，导致 AD 产生的甲烷产量减少。综上所述，青贮比真菌预处理更适合巨蔺的储存及其通过 AD 产生甲烷。
