The significance of Fe(III) reducing bacteria in U(VI) bioremediation and energy production by sediment fuel cells
Iron metabolism sedimentary environments uranium contaminated sediments geochemistry pathogenic bacteria
2015/1/28
Dissimilatory Fe(III) reduction is one of the most significant metabolisms in sedimentary environments. Molecular and geochemical studies conducted on uranium contaminated sediments suggested that Fe(...
Meiofauna enhances organic matter mineralization in soft sediment ecosystems

2014/4/4
We investigated the influence of meiofauna on the benthic decomposition of a radiolabeled diatom bloom by
measuring the production of 14

in a laboratory microcosm. Mineralization of the diatom ...
Studies on Sediment Characteristics of Madhurantakam Lake, Tamilnadu, India
Ostracod Lake Benthos
2010/3/29
We report the results of quantitative and qualitative investigations of the ostracod fauna of the benthos of Madhurantakam Lake in Tamilnadu, India. Five species of ostracod were recorded from the ben...
Studies on Sediment Toxicity Bioassays Using Chironomus thummi K., 1911 Larvae
Zinc copper lead lethality concentration Chironomus thummi larvae bioassay
2010/3/30
The acute toxicity of zinc, copper and lead to freshwater dipteran Chironomus thummi larvae was evaluated by static bioassays, calculating the LC50 (lethality concentration for 50%). Mortality increas...
Effects of Gut Sediment Contents on Heavy Metal Levels in the Amphipod Corophium volutator(Pallas)
Corophium volutator copper zinc cadmium sediment gut
2010/3/31
Concentrations of copper, zinc and cadmium were determined in Corophium volutator (with and without gut contents) exposed for 4 and 10 days to contaminated sediment. Significant differences were obser...
Influence of Sediment on Heavy Metal Uptake by the Polychaete Arenicola marina
Arenicola marina cast lugworm heavy metal sediment
2010/4/1
In this study, the suitability of the polychaete Arenicola marina as a test organism using clean intertidal sediment contaminated with copper, zinc and cadmium was evaluated. Metal levels in casts wer...
