Sulfate reduction in profundal sediments in Lake Kizaki, Japan

Abstract: The sulfate reduction rate was measured for almost four years in the profundal sediments of Lake Kizaki, a mesotrophic lake in central Japan. The rate was generally highest in the surface layer and decreased with depth. Seasonally, sulfate reduction tended to be high in spring and summer, and then to decrease until the end of stratification (December) in spite of a constant in situ temperature of around 6 "C, although fluctuations were found in every year. The rate also fluctuated greatly according to year. Th… Show more

“…Half-saturation constants derived from core incubation experiments have provided further support for this hypothesis (Smith and Klug, 1981;Boudreau and Westrich, 1984;Li et al, 1996). Presumably, the development of a high affinity uptake system for sulfate by SRB in freshwater environments allows them to cope with the low in situ sulfate concentrations (Purdy et al, 2001).…”

“…The 35 S radiotracer technique has been extensively used for measuring sulfate reduction rates and rate distributions in sediments (e.g., Jørgensen, 1978;Thode-Andersen and Jørgensen, 1989;Li et al, 1996;Hurtgen et al, 1999;Gribsholt and Kristensen, 2003). The large amount of available in situ rate data contrasts with the limited attempts to derive and calibrate predictive mathematical rate models for sulfate reduction.…”

“…These half saturation constants do not indicate the existence of high sulfate affinity in marine communities of SRP or the adaptation of sulfate reducers to low sulfate concentration, such as deep down in the methane zone. However, in freshwater systems with sulfate concentrations of only 10-200 lM, sulfate is consumed efficiently within the top several cm of lake sediment and apparent K m values are low (Smith and Klug, 1981;Urban et al, 1994;Li et al, 1996). This shows that sulfate reducers adapted to low sulfate concentrations are indeed present in limnic environments (Holmer and Storkholm, 2001).…”

“…Anaerobic conditions, sulfates and available OM are known to be the major factors that determine the activity of sulfate-reducing bacteria (SRB), which play a crucial role in the terminal anaerobic organic carbon mineralization, while temperature is only partially responsible for the seasonal SRB activity in aquatic ecosystems (Li et al, 1996;Holmer and Storkholm, 2001). During the summer-autumn period in bottom sediments of leaf litter accumulation zones under sufficient sulfate concentration, the activity of sulfate reducing bacteria was promoted due to accumulation of labile organic matter and partly because of temperature.…”
