Assessment of temperature dynamics and microbial community responses in aerobic membrane bioreactors from mesophilic to hyper-thermophilic conditions

This study investigates the impact of temperature variations on the performance of an aerobic membrane bioreactor (MBR) as it transitions from mesophilic (30 °C) to hyper-thermophilic (65 °C) conditions. The microbial community structure was analyzed using 16S rRNA gene sequencing to assess how temp...
