Cyanobacteria-dominated microbial mat communities are restricted to oligotrophic environ- ments in a stromatolitic cyanobacterial crust which devel- oped in a Mediterranean stream.

Sisodia Department of Geology, University of Jodhpur, Jodhpur 342 001, India Small spherical bodies identified as fossil cyanobacteria have been found within or in the vicinity of stromatolites in the Precambrian Aravalii phosphorites of Udaipur. cyanobacteria are difficult to grow axenically. Experimental work can be confounded by their heavy mineralization, making high-resolution stud-ies of their internal structure difficult or impossible. Although stromatolites are best regarded as microbial communities rather than individual stro-matolite-building species, in many cases a small Stromatolites are layered mounds, columns, and sheet-like sedimentary rocks.

Although stromatolites are best regarded as microbial communities rather than individual stro-matolite-building species, in many cases a small Stromatolites are layered mounds, columns, and sheet-like sedimentary rocks. They were originally formed by the growth of layer upon layer of cyanobacteria, a single-celled photosynthesizing microbe that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils.

They were originally formed by the growth of layer upon layer of cyanobacteria, a single-celled photosynthesizing microbe that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils. a rocky mass consisting of layers of calcareous material and sediment formed by the prolific growth of cyanobacteria: such structures date back to Precambrian times Derived forms of stromatolite stromatolitic ( strəʊˌmætəˈlɪtɪk ), adjective Antarctic lithic cyanobacterial communities are therefore stratified, as in soil biofilms of Alexander Island, the benthic stromatolitic mars of ice-covered hypersaline lakes in the McMurdo Dry Valleys, and the endolithic communities within translucent Beacon sandstone outcrops of Victoria Land.

(geology) A laminated, columnar, rock-like structure built over geologic time by microorganisms such as cyanobacteria. Most modern and ancient stromatolites occur in carbonate sediments and sedimentary rocks, but they can form by trapping and binding of any sediment particles.
