The Biogeochemistry of Hypersaline Microbial Mats
1995Microbial mats are structurally coherent macroscopic accumulations of microorganisms. Photosynthetic mats offer an opportunity to examine the dynamics of a complete microbial ecosystem. Microbial mats construct laminated “miniature reefs” called stromatolites, which occur typically as carbonate rocks and are among the oldest, most abundant fossil ...

Analysis of diurnal and vertical microbial diversity of a hypersaline microbial mat
Archives of Microbiology, 2007Microbial mats are prokaryotic communities that provide model systems to analyze microbial diversity and ecophysiological interactions. Community diversity of microbial mat samples was assessed at 8:00 a.m. and 3:00 p.m. in a combined analysis consisting of 16S rRNA-denaturing gradient gel electrophoresis (DGGE) and phospholipid fatty acid (PLFA ...

Methylation of mercury and tin by estuarine microbial mats
Marine Pollution BulletinAfter 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 ...

Archean Microbial Mat Communities
Annual Review of Earth and Planetary Sciences, 2011Much of the Archean record of microbial communities consists of fossil mats and stromatolites. Critical physical emergent properties governing the evolution of large-scale (centimeters to meters) topographic relief on the mat landscape are (a) mat surface roughness relative to the laminar sublayer and (b) cohesion. These properties can be estimated for

Microbial mats and the early evolution of life
Trends in Ecology & Evolution, 1990Microbial mats have descended from perhaps the oldest and most widespread biological communities known. Mats harbor microbes that are crucial for studies of bacterial phylogeny and physiology. They illustrate how several oxygen-sensitive biochemical processes have adapted to oxygen, and they show how life adapted to dry land long before the rise of ...

Awareness of biofilms and microbial mats is not a modern attribute (see, in this context, Krumbein, 1993, 1994; Krumbein et al., 2003). Slippery surfaces, mucilage-embedded organic films, plaques, or rock patina may have not only stimulated olfactory, tactile, and visual senses, but also initiated questions about reasons.
