Upwelling systems contain a high diversity of pelagic microorganisms and their composition and activity are defined by factors like temperature and nutrient concentration. Denaturing gradient gel electrophoresis (DGGE) technique was used to verify th

REsUmo Os estudos sobre o ciclo do mercurio (Hg) na regiao amazonica durante os ultimos 20 anos indicam que a atual fonte de contaminacao do meio aquatico e o desmatamento. O Hg que se deposita no sistema terrestre tem grande afinidade com os oxihidr

Laboratory radioassays were made to study mercury (Hg) methylation together with bacterial production in the periphyton of two aquatic macrophytes, the submerged Myriophyllum spicatum, from a constructed wetland in Sweden and the floating Eichhornia

The ecological interaction between microorganisms and seaweeds depends on the production of secondary compounds that can influence microbial diversity in the water column and the composition of reef environments. We adapted the (3)H-leucine incorpora

Mercury methylation and bacterial activity associated to tropical phytoplankton

Autor: Jean Remy Davée Guimarães, Sérgio A. Coelho-Souza, Sandra M.F.O. Azevedo, Marcio Rodrigues Miranda, Jane B.N. Mauro

Publikováno v: The Science of the total environment. 364(1-3)

The methylated form of mercury (Hg), methylmercury (MeHg), is one of the most toxic pollutants. Biotic and/or abiotic methylation, often associated to sulfate-reducing bacteria metabolism, occurs in aquatic environments and in many tropical areas, mo
