In the present study, ectopic fermentation systems were treated with both solid and liquid waste from livestock. Then, the various physicochemical properties and compositions of microbial communities in different waste straws treatments were compared. The addition of thermophilic bacteria was beneficial to the decomposition of litter, and it improved the fermentation process. Proteobacteria, Bacteroidetes, and Firmicutes were the predominant types in the fermentation vessels, and the presence of the phyla Proteobacteria and Bacteroidetes was correlated with factors prevailing in the mature phase. Furthermore, pig manure with sawdust, rape stem, and rice chaff and pig manure with sawdust, rice straw, and rice chaff vessels had higher concentrations of dissolved nitrogen, which were conducive to the conversion of fermentation wastes into useful fertilizer. These results demonstrate the feasibility of using rape stem and rice straw as padding materials during the treatment of both liquid and solid livestock waste in ectopic fermentation systems.
在本研究中，异位发酵系统同时处理来自牲畜的固体和液体废物。然后，比较了不同废秸秆处理中微生物群落的各种物理化学性质和组成。添加嗜热菌有利于垃圾分解，并改善发酵过程。在发酵容器中，变形菌门、拟杆菌门和厚壁菌门是主要类型，而变形菌门和拟杆菌门的存在与成熟阶段占主导地位的因素有关。此外，猪粪与木屑、油菜秸秆和稻壳以及猪粪与木屑、稻草和稻壳容器的溶解氮浓度较高，有利于将发酵废物转化为有用的肥料。这些结果表明，在异位发酵系统中处理液体和固体牲畜废物时，油菜秸秆和水稻秸秆可用作填充材料。
