Robust performance of mesophilic anaerobic digestion enabled by microbial functional redundancy

Study evaluates the effect of lowering operating temperatures in pilot-scale digesters on gas yields, digestate chemistry, and microbial dynamics. Six continuously stirred tank reactors are acclimated at 55C before three are gradually reduced to 48C, while three remain at 55C本研究评估了中试规模厌氧消化器（digesters）降低运行温度后，对产气率、消化物化学特性以及微生物群落动态的影响。实验设置6台连续搅拌槽式反应器（Continuously Stirred Tank Reactors），先在55℃条件下完成驯化，随后将其中3台的运行温度逐步降至48℃，剩余3台维持55℃不变。
