متن کاملMethane turnover and methanotrophic communities in arctic aquatic ecosystems of the Lena Delta, Northeast Siberia.
Large amounts of organic carbon are stored in Arctic permafrost environments, and microbial activity can potentially mineralize this carbon into methane, a potent greenhouse gas. In this study, we assessed the methane budget, the bacterial methane oxidation (MOX) and the underlying environmental controls of arctic lake systems, which represent substantial sources of methane. Five lake systems l...
متن کاملBacterial community structure and carbon turnover in permafrost-affected soils of the Lena Delta, northeastern Siberia.
Arctic permafrost environments store large amounts of organic carbon. As a result of global warming, intensified permafrost degradation and release of significant quantities of the currently conserved organic matter is predicted for high latitudes. To improve our understanding of the present and future carbon dynamics in climate sensitive permafrost ecosystems, the present study investigates st...
متن کاملBacterial diversity and community structure in polygonal tundra soils from Samoylov Island, Lena Delta, Siberia.
During the Arctic summer, bacteria are active above the permafrost in an environment with sharp temperature and oxygen gradients. The present study addressed the diversity and abundance of bacteria in soil layers near the surface and above the permafrost of the rim and center of a low-centered polygon in the Lena Delta, Siberia. 16S rRNA gene clone libraries revealed the presence of all major s...
متن کاملAerobic methanotrophic bacteria of cold ecosystems.
This review summarizes the recent advances in understanding the ecophysiological role and structure-function features of methanotrophic bacteria living in various cold ecosystems. The occurrence of methanotrophs in a majority of psychrosphere sites was verified by direct measurement of their methane-utilizing activity, by electron microscopy and immunofluorescent observations, and analyses of s...
