Morphological and chemical transformations of , during early diagenesis in hypersaline microbial mat that are anoxic and not reached by light. Nevertheless, cyanobacterial remains are often preserved in the sedimentary column. In the virtual absence of bioturbation, the original stratigraphy remains conserved in the sedimentary record. Hence, sediments with microbial mats often comprise an activel

On the significance of solar ultraviolet radiation for the ecology of microbial mats of the total incident irradiance (Table 1). However, they may produce disproportionately large biological effects because they activate many photochemical reactions involving molecules of central biological importance. The consequence of these photoreactions is usually detrimental to the cellular m

Osmotic adaptation of microbial communities in hypersaline microbial matsd by the high salt concentrations. Most halophilic and halotolerant eubacteria and eukaryotic protists exclude salt, and synthesize or accumulate high concentrations of organic solutes that do not interfere with intracellular enzymatic activities (“osmotic solutes” or “compatible solutes”).
