Methylation of mercury and tin by estuarine microbial mats

Marine Pollution Bulletin
After tin and mercury salts were added to estuarine microbial mats increasing amounts of methyltin and methylmercury, respectively, were formed over a 30 to 100 hour time period. Inhibition of the methylation by molybdate, a metabolic inhibitor of sulfate reduction, stimulation by pyruvate addition and lack of methylation by sterilized mats, were ...

Microbial Mats

2011
crobial mats are laminated microbial communities that generally develop in aqueous environments under conditions that exclude fauna. The biogeochemical cycles in microbial mats are usually largely closed, although small fluxes of elements are exchanged with the geo-, bio-, and atmosphere.

Diazotrophic Microbial Mats

2010
Microbial mats have been the focus of scientific research for a few decades. These small-scale ecosystems are examples of versatile benthic communities of microorganisms, usually dominated by phototrophic bacteria (e.g., Krumbein et al., 1977; Jørgensen et al., 1983). They develop as vertically stratified populations of functionally different groups of

Microbial mats: A joint venture

Marine Geology, 1993
Microbial mats characteristically are dominated by a few functional groups of microbes: cyanobacteria, colorless sulfur bacteria, purple sulfur bacteria, and sulfate-reducing bacteria. Their combined metabolic activities result in steep environmental microgradients, particularly of oxygen and sulfide.The driving force of most microbial mats is ...

Interfacial Microbial Mats and Biofilms

2001
Abstract Biofilms and microbial mats can be defined as surface-associated layers of microbial cells embedded in extracellular polymeric substance (EPS; Characklis and Marshall, 1989; Stal and Caumette, 1994). Biofilms cover solid surfaces, while mats cover sediments.

Microbial Spheres from Microbial Mats

2003
Filamentous cyanobacteria from the LPP-group (Lyngbya sp., Plectonema sp., Phormidium sp.), diatoms and heterotrophic bacteria are the dominant microorganisms of North Sea microbial mats (Gerdes et al., 1986). Cultivated on solid or liquid media the cyanobacteria produce motile trichomes.
