An algal bloom of Peridinium gatunenese generally precedes the annual maximum of methane release from the profundal sediment of Lake Kinneret. Therefore, we investigated the response of the sediment methanogenic microbial community to simulated algal deposition. Addition of algal biomass on top of sediment cores resulted in increased CH4 production rates and concentrations of the fermentation products acetate and propionate in the upper 4‐cm layers with maximum values at 1‐cm depth. Addition of…

Structure and function of methanogenic microbial communities in sediments of Amazonian lakes with different water types.

This study showed that function of the microbial communities may be understood on the basis of their structures, which in turn are determined by environmental heterogeneity.

Composition of the archaeal community involved in methane production during the decomposition of Microcystis blooms in the laboratory.

Higher temperatures enhanced the methanogenic transformation of the Microcystis biomass and the phylogenetic dominance of hydrogenotrophic methanogens, suggesting that H( 2) and CO(2) might be the primary substrates for CH(4) production during MicrocyStis decomposition without the participation of lake sediment.

Changes in the Substrate Source Reveal Novel Interactions in the Sediment-Derived Methanogenic Microbial Community

The analysis of communities that developed on various carbon sources casts new light on the ecophysiology of the recently described bacterial phylum Caldiserica and methanogenic Archaea representing the genera Methanomassiliicoccus and Methanothrix.

Vertical variation of bulk and metabolically active prokaryotic community in sediment of a hypereutrophic freshwater lake

The results indicate that rRNA analysis may be more effective than rDNA analysis for evaluation of relationships between actual microbial processes and material cycling in lake sediments.

Effects of algal and terrestrial carbon on methane production rates and methanogen community structure in a temperate lake sediment

Summary 1. Sources of atmospheric CH4 are both naturally occurring and anthropogenic. In fact, some anthropogenic activities may influence the production of CH4 from natural sources, such as…

Dissolved CH4 coupled to Photosynthetic Picoeukaryotes in Oxic Waters and Cumulative Chlorophyll-a in Anoxia

Abstract. CH4 emissions from reservoirs are responsible for the majority of the atmospheric climatic forcing of these aquatic ecosystems, comparable to emissions from paddies or biomass burning.…

Stratification of Archaea in the Deep Sediments of a Freshwater Meromictic Lake: Vertical Shift from Methanogenic to Uncultured Archaeal Lineages

An integrated molecular approach was performed to gain information on the structure, composition, abundance and vertical stratification of archaeal communities thriving in anoxic freshwater sediments along a gradient of sediments encompassing 130 years of sedimentation.

Influences of eutrophication on methanogenesis pathways and methanogenic microbial community structures in freshwater lakes.

Stable isotope fractionation during the methanogenic degradation of organic matter in the sediment of an acidic bog lake, Lake Grosse Fuchskuhle

Lake Grosse Fuchskuhle is an acidic bog lake, which develops an anoxic hypolimnion during the summer season, so that sediment organic matter is degraded anaerobically to CH4 and CO2. The δ13C values…

Effect of algal deposition on acetate and methane concentrations in the profundal sediment of a deep lake (Lake Constance)

The results show that phytoplankton blooms may cause a seasonal variation of acetate and CH4 in profundal sediments of deep lakes despite the constant low temperature and indicate that acetate is the dominant substrate for methanogenic bacteria in the Profundal Sediments of Lake Constance.

Evidence for anaerobic syntrophic acetate oxidation during methane production in the profundal sediment of subtropical Lake Kinneret (Israel).

Methane production in samples of the profundal sediment from Lake Kinneret showed Methanomicrobiaceae as the dominant methanogenic group, whereas acetoclastic methanogens could not be detected, indicating that CH(4) was produced exclusively from acetate.

It is shown that acetate carbon was predominantly consumed by acetoclastic methanogens in profundal Lake Kinneret sediment, while it was also utilized by a small and heterogeneous community of bacteria.

Microbial Response of a Freshwater Benthic Community to a Simulated Diatom Sedimentation Event: Interactive Effects of Benthic Fauna

The results indicate that Chironomus larvae compete with sediment bacteria for available organic substrates, and this was interpreted as a result of faster decomposition of diatoms in treatments with chironomids, which was validated by a faster decline of ATP and chlorophyll a in the sediment.
