Abstract

Abstract

Sediments from two hardwater and six softwater lakes of varying trophic levels from Wisconsin were incubated under conditions which permitted continued synthesis of methane. Rates of acetylene reduction indicated that, on the average, sediments from hardwater and softwater lakes may fix 37 and 7.7 ng of N, respectively, per gram (dry weight) per day. The rate of acetylene reduction diminished in the presence of nitrogenase inhibitors.
