Bacterial Community Structures in Freshwater Polar Environments of Svalbard
Two thirds of Svalbard archipelago islands in the High Arctic are permanently covered with glacial ice and snow. Polar bacterial communities in the southern part of Svalbard were characterized using an amplicon sequencing approach. A total of 52,928 pyrosequencing reads were analyzed in order to reveal bacterial community structures in stream and lake surface water samples from the Fuglebekken ...
متن کاملMicrobiological transformations of mercury species in aquatic environments
Biogeochemical cycle of mercury (Hg) is a complicated series of biotic and abiotic reactions, from which formation of monomethylmercury (MeHg) is widely considered as the most important, due to the proven toxicity of MeHg [1]. Organomercury forms have a pronounced capability of bioaccumulation (incorporation in cells and tissues of living organisms) and biomagnification (transport through troph...

متن کاملAromatic donor-acceptor interactions in non-polar environments.
We have evaluated the strength of aromatic donor-acceptor interactions between dialkyl naphthalenediimide and dialkoxynaphthalene in non-polar environments. (1)H NMR, UV-vis spectroscopy and isothermal titration calorimetry were used to characterise this interaction. We concluded that the strength of donor-acceptor interactions in heptane is sufficient to drive supramolecular assemblies in this...
متن کاملMercury methylation by novel microorganisms from new environments.
Microbial mercury (Hg) methylation transforms a toxic trace metal into the highly bioaccumulated neurotoxin methylmercury (MeHg). The lack of a genetic marker for microbial MeHg production has prevented a clear understanding of Hg-methylating organism distribution in nature. Recently, a specific gene cluster (hgcAB) was linked to Hg methylation in two bacteria.1 Here we test if the presence of ...
