在萨尔河中，甲烷氧化细菌的分布和它们的代谢活性的垂直和纵向剖面。在沉积物表面约两个数量级以上的甲烷氧化剂检测比上覆水。在河流中以及在实验室实验中，甲烷氧化速率与甲烷浓度密切相关。沉积物中产甲烷细菌产生的甲烷大部分逃逸到大气中。平均只有1.2%的甲烷在水相中被氧化。
In the River Saar, the distribution of methane-oxidizing bacteria and their metabolic activity were determined in vertical and longitudinal profiles. At the sediment surface about two orders of magnitude more methane oxidizers were detected than in the overlying water. In the river as well as in laboratory experiments, the rate of methane oxidation was closely related to the concentration of methane. Most of the methane produced by methanogenic bacteria in the the sediment escaped into the atmosphere. On the average only 1.2% of the produced methane was oxidized in the water phase.
