Latitudinal distribution of microbial communities in anaerobic biological stabilization ponds: effect of the mean annual temperature.

ABSTRACT: Considering wide utilization and high methane fluxes from anaerobic biological stabilization ponds (ABSPs), understanding the methanogenesis in ABSPs is of fundamental importance. Here we investigated the variation and impact factors of methanogenesis in seven ABSPs that spanned from the north to the south of China. Results showed that methanogen abundance (7.7 × 10⁹ -8.7 × 10¹⁰  copies g^-1 dry sediment) and methanogenic activities (2.2-21.2 μmol CH₄  g^-1  dry sediment h^-1 ) were considerable for all sediments. Statistical analysis demonstrated that compared with other factors (ammonium, pH, COD and TOC), mean annual temperature (MAT) showed the lowest P value and thus was the most important influencing factor for the methan
