在牛粪和玉米秸秆混合发酵系统中，研究了添加甘蓝渣对发酵产甲烷的影响。四个实验组，每个包含55 g的基质，设置如下：100%牛粪（C）; 36%白菜和64%牛粪（CC）; 36%稻草和64%牛粪（SC）;和18%白菜，18%稻草，和64%牛粪（CSC）。发酵7天后，CSC组的最大甲烷产量为134 mL，分别是CC、SC和C组的2.81倍、1.78倍和1340倍。CW处理的CSC组增强纤维素酶活性和丰富的可培养的纤维素降解细菌菌株。Miseq测序数据显示，CSC组中的主要门是拟杆菌门，其包含大多数纤维素降解细菌。我们的研究结果表明，CW处理提高纤维素降解和促进甲烷产生。
The effects of cabbage waste (CW) addition on methane production in cow dung and corn straw co-fermentation systems were investigated. Four experimental groups, each containing 55 g of substrate, were set up as follows: 100% cow dung (C); 36% cabbage and 64% cow dung (CC); 36% straw and 64% cow dung (SC); and 18% cabbage, 18% straw, and 64% cow dung (CSC). After seven days of fermentation, the maximum methane yield was 134 mL in the CSC group, which was 2.81-fold, 1.78-fold, and 1340-fold higher than that obtained in the CC, SC, and C groups, respectively. CW treatment of the CSC group enhanced cellulase activity and enriched culturable cellulose-degrading bacterial strains. Miseq sequencing data revealed that the predominant phylum in the CSC group was Bacteroidetes, which contains most of the cellulose-degrading bacteria. Our results suggested that CW treatment elevated cellulose degradation and promoted methane production.
