Comments Temperature has a direct influence on the reaction kinetics of metabolic processes, which can be described by their Ea and Q10 values. Therefore, researchers calculated the apparent Ea and Q10 values for the different aspects of oxygen community metabolism in the artificial mat and compared those with values previously described for other benthic environments.
