2017年4月19日 · In illuminated environments most microbial mats are built by cyanobacteria, oxygenic photoautotrophic bacteria that colonize bare sediments and form the basis of the microbial mat through the primary production of organic matter synthesized from the photosynthetic fixed carbon dioxide.

2018年1月1日 · Microbial mats as a study model is an easily accessible viable laboratory, and these communities present with varying degrees of complexity from simple non-phototrophic mats, YNP mats with a low diversity of phototrophs, to the complex hypersaline and mats obtained from Guerrero Negro, México and Llamará, Chile.

Phototrophic biofilms are microbial communities generally comprising both phototrophic microorganisms, which use light as their energy source, and chemoheterotrophs. [1] Thick laminated multilayered phototrophic biofilms are usually referred to as microbial mats or phototrophic mats (see also biofilm ). [ 2 ]

2014年4月7日 · Two unicyanobacterial consortia (UCC-A and UCC-O) containing distinct species of cyanobacteria were isolated from a subsample of the Hot Lake phototrophic microbial mat. These consortia were passaged until they reached functional stability, as determined by proteomic and metabolomic analyses that showed no significant changes for greater than 6 ...

Phototrophic microbial mats are ideal model systems for ecological and evolutionary analysis of highly diverse microbial communities. Microbial mats are small-scale, nearly closed, and self-sustaining benthic ecosystems that comprise the major element cycles, trophic levels, and …

Phototrophic microbial mats are compact ecosystems composed of highly interactive organisms in which energy and element cycling take place over millimeter-to-centimeter-scale distances. Although microbial mats are common in hypersaline environments, they have not been extensively characterized in systems dominated by divalent ions.

Microbial mats are exceptionally productive ecosystems in which cyanobacteria are the main primary producers, although eukaryotic microalgae such as diatoms and anoxygenic phototrophic bacteria may contribute to the primary production as

2014年11月1日 · Phototrophic microbial mats are ideal model systems for ecological and evolutionary analysis of highly diverse microbial communities. Microbial mats are small-scale, nearly closed, and self-sustaining benthic ecosystems that comprise the major element cycles, trophic levels, and food webs.

2014年8月11日 · Phototrophic microbial mats are ideal model systems for ecological and evolutionary analysis of highly diverse microbial communities. Microbial mats are small‐scale, nearly closed, and self‐sustaining benthic ecosystems that comprise the major element cycles, trophic levels, and food webs.

2006年8月3日 · We investigated the genotypic diversity of oxygenic and anoxygenic phototrophic microorganisms in microbial mat samples collected from three hot spring localities on the east coast of Greenland. These hot springs harbour unique Arctic microbial ecosystems that have never been studied in detail before.
