Eucaryotic Diversity in a Hypersaline Microbial Mat [PDF]

Applied and Environmental Microbiology, 2008
ABSTRACT To determine the eucaryotic diversity of the hypersaline Guerrero Negro microbial mat, we amplified 18S rRNA genes from DNA extracted from this mat and constructed and analyzed clone libraries. The extent of eucaryotic diversity detected was remarkably low, only 15 species among 890 clones analyzed.

Environmental and Biological Influences on Carbonate Precipitation Within Hot Spring Microbial Mats in Little Hot Creek, CA

Frontiers in Microbiology, 2018
Microbial mats are found in a variety of modern environments, with evidence for their presence as old as the Archean. There is much debate about the rates and conditions of processes that eventually lithify and preserve mats as microbialites.

Microbial Diversity of Pinnacle and Conical Microbial Mats in the Perennially Ice-Covered Lake Untersee, East Antarctica

Frontiers in Microbiology, 2020
Antarctic perennially ice-covered lakes provide a stable low-disturbance environment where complex microbially mediated structures can grow. Lake Untersee, an ultra-oligotrophic lake in East Antarctica, has the lake floor covered in benthic microbial mat

Localized electron transfer rates and microelectrode-based enrichment of microbial communities within a phototrophic microbial mat

Frontiers in Microbiology, 2014
Phototrophic microbial mats frequently exhibit sharp, light-dependent redox gradients that regulate microbial respiration on specific electron acceptors as a function of depth.

Metagenomic and metabolic profiling of nonlithifying and lithifying stromatolitic mats of Highborne Cay, The Bahamas. [PDF]

PLoS ONE, 2012
BACKGROUND: Stromatolites are laminated carbonate build-ups formed by the metabolic activity of microbial mats and represent one of the oldest known ecosystems on Earth. In this study, we examined a living stromatolite located within the Exuma Sound, The

Daily Rhythmicity in Coastal Microbial Mats [PDF]

, 2021
To understand the ecological role of circadian rhythms in prokaryotes, we often move from an initial observation in nature to an in-depth analysis of isolated species under laboratory conditions. The other way around is less common: newly found insights on circadian control of microbial physiology and metabolic interactions are rarely tested in the ...

Extant Earthly Microbial Mats and Microbialites as Models for Exploration of Life in Extraterrestrial Mat Worlds

Life, 2021
As we expand the search for life beyond Earth, a water-dominated planet, we turn our eyes to other aquatic worlds. Microbial life found in Earth’s many extreme habitats are considered useful analogs to life forms we are likely to find in extraterrestrial

Investigation of soil microbiome under the influence of different mulching treatments in northern highbush blueberry

AMB Express, 2021
Microbial communities on soil are fundamental for the long-term sustainability of agriculture ecosystems. Microbiota in soil would impact the yield and quality of blueberries since microbial communities in soil can interact with the rhizosphere of plant.

Microbial mats: an ecological niche for fungi [PDF]

Frontiers in Microbiology, 2013
Fungi were documented in tropical hypersaline microbial mats and their role in the degradation of complex carbohydrates (exopolymeric substance - EPS) was explored. Fungal diversity is higher during the wet season with Acremonium, Aspergillus, Cladosporium, and Penicillium among the more common genera.
