摘要:
厌氧发酵是解决秸秆和畜禽粪等农业废弃物污染的重要途径,为实现秸秆和牛粪的资源化利用,研究稻秆和牛粪混合物料干、湿厌氧发酵特性,并对混合物料发酵前后的菌群结构进行分析。结果表明,稻秆与牛粪混合物料干、湿发酵的挥发性脂肪酸(VFAs)均以乙酸和丙酸为主,发酵pH值均在5.6~7.7之间变化,湿发酵的总固体浓度(total solid,简称TS)累积产甲烷量(63.8 mL/g)较干发酵(36.9 mL/g)提高73.90%,发酵前后菌群结构发生较大变化,细菌的优势菌群由消化链球菌(Peptostreptococcaceae)、瘤胃菌(Ruminococcaceae)、梭菌(Clostridiaceae.1)和理研菌(Rikenellaceae)转变为普雷沃氏菌(Prevotellaceae)、毛螺菌(Lachnospiraceae)和互养菌(Synergistaceae),古菌的优势菌群由甲烷杆菌(Methanobacteriaceae)和甲烷球菌(Methanosarcinaceae)转变为以乙酸代谢为主的甲烷球菌(Methanosarcinaceae)。
