Proterozoic stromatolite microfossils (preserved by permineralization in silica) include cyanobacteria and possibly some forms of the eukaryote chlorophytes (that is, green algae). …

2012年1月1日 · 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 …

2024年3月10日 · Stromatolites are layered accretions of microorganisms, primarily cyanobacteria, mixed with sedimentary grains. These formations often occur in shallow water environments. …

At right is a layered stromatolite, produced by the activity of ancient cyanobacteria. The layers were produced as calcium carbonate precipitated over the growing mat of bacterial filaments; …

2021年1月18日 · With a citizen scientist’s understanding, stromatolites are stony structures built by colonies of microscopic photosynthesising organisms called cyanobacteria. As sediment …

2013年11月15日 · Stromatolites ("layered rocks") are rocky structures made by photosynthetic cyanobacteria. The microbes secrete sticky compounds that bind together sediment grains, …

Modern stromatolites represent a significant resource for studying microbial ecology and evolution. A preliminary investigation was undertaken employing specific genetic probes to …

2024年4月4日 · Cyanobacteria are photosynthetic microorganisms, fundamental to aquatic ecosystems, while stromatolites are layered structures formed by the trapping of sediment by …

2009年1月15日 · Although the stromatolites of Highborne Cay contain a wide range of metabolically diverse organisms, photosynthetic cyanobacteria are the driving force for …

2018年5月22日 · Cyanobacteria play a key role in the formation of microbialites, being usually the main primary producers in the microbial mats associated with modern stromatolites. They …
