Min Chen of the University of Sydney in Australia, and her colleagues, went looking for interesting chlorophyll in the stromatolites there because the water in which they live - and the trapped sediment that bulks them out - filter out much of the visible light reaching the stromatolitic cyanobacteria.

Stromatolites are formed by primitive one-celled cyanobacteria, which are also known as blue-green algae. These deposits consist of thin, alternating dark and light layers. The photosynthesizing cyanobacteria can be found in a wide range of environments including rivers, soils, lakes, and shallow shelves.

Cyanobacteria are Gram-negative bacteria. Five types of cyanobacteria have been identified as toxin producers, including two strains of Anabaena flosaquae, Aphanizomenon flosaquae, Microcystis aeruginosa and Nodularia species. Cyanobacterial toxins are of three main types: hepatotoxins, neurotoxins and lipopolysaccharide (LPS) endotoxins. Their cyanobacteria contain a newly discovered form of chlorophyll – the fifth known filter out much of the visible light reaching the stromatolitic cyanobacteria.

For many years they were classified in the plant kingdom along with algae, but discoveries made possible by the electron microscope and new biochemical Cyanobacteria stromatolites were the first living organisms to produce oxygen.

Cyanobacteria are found to be a primary organism in the formation of modern microbial carbonates. These prokaryotic bacteria (slang name is blue-green algae owning to pigmentation involved in photosynthesis) are now only found in areas where there is reduced grazing and burrowing by other organisms, and a low occurrence of macro-algae and plants.

A stromatolite may grow to a meter or more. Although they are rare today, fossilized stromatolites provide records of ancient life on Earth. The phylum Cyanobacteria encompasses three main types of microbial structures: (1) isolated, coccoid or tubular filaments eventually with pseudoramifications, or true bifurcations; with calcifications in the mucilaginous sheath surrounding the cell wall; (2) bioconstructions of types stromatolite, thrombolites, oncoids, cyanoids, microbialites or dendrolites of Epiphytaceae, Chabakoviaceae, and Frutexites; (3) nodular colonies composed of single to bifurcated spans of calcified filaments Cyanobacteria are often the key organisms comprising microbial mats. They form dense micrometer-scale communities in which the full plethora of microbial metabolism can be present. Such mats are therefore excellent model systems and because of their analogy with Precambrian stromatolites they are also attractive subjects for evolutionary studies. Stromatolites are layered biochemical accretionary structures formed in shallow water by the trapping, binding, and cementation of sedimentary grains by biofilms (microbial mats) of microorganisms, especially cyanobacteria. Stromatolites left behind by cyanobacteria are the oldest known fossils of life on Earth.

INTRODUCTION Macorbiota In marked contrast to the paucity of evidence of biological activity during (geology) A laminated, rock-like structure built over geologic time by microorganisms such as cyanobacteria. A laminated, columnar, rock-like structure constituting a large share of all fossils from 3.5 to 0.5 billion years ago, with some still being formed at present, some or all of which result from the deposit of minerals by microorganisms such as cyanobacteria. Stromatolites are created by cyanobacteria, also called blue-green algae. These microscopic life forms are not really algae at all but bacteria that have the ability to carry out photosynthesis. It is the process of photosynthesis combined with the growth of the cyanobacteria that creates the distinctive dome-shaped, finely layered rocks we call stromatolites.

These stromatolites represented first biological colonization after: (i) subaerial exposure in the palustrine environment (i.e. at the beginning of deepening cycles); or (ii) erosion due to surge Cyanobacteria can be found in almost every terrestrial and aquatic habitat – oceans, fresh water, damp soil, temporarily moistened rocks in deserts, bare rock and soil, and even Antarctic rocks.

Stromatolites are fossilized colonies formed by blue-green algae.

It is the process of photosynthesis combined with the growth of the cyanobacteria that creates the distinctive dome-shaped, finely layered rocks we call stromatolites. As the cyanobacteria grows it uses up the carbon dioxide in the surrounding water. That causes calcium carbonate to precipitate or solidify from its dissolved state in the water.

Both are formed by the organisms growing on a particular surface or substrate to which they gradually bind consecutive layers of very fine sediment and precipitated A usually rounded or columnar sedimentary structure consisting of alternating layers of carbonate or silicate sediment and fossilized microbial mats, produced over geologic time by the trapping, binding, or precipitating of minerals by groups of microorganisms, primarily cyanobacteria.
