摘要(Abstract)：

随着全球能源需求的增加和环境问题的加剧，煤的厌氧发酵技术因其能够将煤炭转化为甲烷等清洁能源逐渐成为研究热点。在不同温度（50℃、60℃、70℃）下进行厌氧发酵实验，通过对比分析各厌氧发酵系统中气相、液相变化及菌群结构的差异，探讨了温度对煤厌氧发酵过程中糖类代谢及效率的影响。结果表明，多糖和还原糖的含量变化趋势在不同温度条件下基本一致，但峰值含量及变化幅度存在显著差异。60℃条件下生物甲烷产量最高，在此温度下，微生物群落结构稳定，水解产酸菌和产甲烷菌的协同作用最佳，糖类代谢途径稳定，代谢效率最佳。本研究揭示了温度对微生物群落结构及糖类代谢途径的调控作用，为煤厌氧发酵技术的开发提供了重要的理论依据。
