Methane, a greenhouse gas, is produced from the activity of methanogenic archaea under anaerobic conditions. Methanogenic activity is dominant in freshwater sediments; however, in estuarine sediments and brackish wetlands, the production and emission of methane has also been determined. Studies on methane emissions in tropical brackish environments have been carried...
In this work the anaerobic digestion of the organic fraction of urban solid waste (OFUSW) was studied in two stages: in the first stage, the hydrolysis and acidogenesis in anaerobic hydrolytic leach bed (AHLB) reactor in batch and continuous to evaluate the effect of the rate runoff and inoculation; in...
The coastal lagoons are characterized by the mixture of fresh and salty water, causing these systems to be extremely dynamic, thus generating a very particular ecological behavior. The bacteria present in the sediments of this ecosystems have a critical role in its functioning, such as the recycling of organic matter,...
