Anaerobic bacteria from hypersaline environments [PDF]

Microbiological Reviews, 1994
Strictly anaerobic halophiles, namely fermentative, sulfate-reducing, homoacetogenic, phototrophic, and methanogenic bacteria are involved in the oxidation of organic carbon in hypersaline environments. To date, six anaerobic fermentative genera, containing nine species, have been described. Two of them are homoacetogens.

First genomic analysis of Platycopioida and phylogenomics across six copepod orders

Cladistics, EarlyView.
Abstract Recent advances in bioinformatics have significantly expanded our understanding of the genetic properties of organisms and have provided valuable insights into their phylogenetic relationships and evolutionary histories. However, molecular phylogenetic studies of the class Copepoda remain limited, and the focus has been mainly on the major ...

Microbial Community Structure and the Persistence of Cyanobacterial Populations in Salt Crusts of the Hyperarid Atacama Desert from Genome-Resolved Metagenomics

Frontiers in Microbiology, 2017
Although once thought to be devoid of biology, recent studies have identified salt deposits as oases for life in the hyperarid Atacama Desert. To examine spatial patterns of microbial species and key nutrient sources, we genomically characterized 26 salt

Near‐infrared confocal imaging reveals the spatial organisation of far‐red photosynthesis in Shark Bay microbial mats and Halomicronema sp.

Journal of Microscopy, EarlyView.
Abstract Far‐red light (FRL) cyanobacteria occupy spectrally filtered habitats where visible wavelengths are depleted but far‐red radiation persists. Shark Bay (Western Australia) stromatolitic microbial mats provide such a habitat, containing subsurface cyanobacterial communities in which chlorophyll d/f (Chl d/f)‐containing phototrophs coexist with ...

Cyanobacterial Diversity in Microbial Mats from the Hypersaline Lagoon System of Araruama, Brazil: An In-depth Polyphasic Study

Frontiers in Microbiology, 2017
Microbial mats are complex, micro-scale ecosystems that can be found in a wide range of environments. In the top layer of photosynthetic mats from hypersaline environments, a large diversity of cyanobacteria typically predominates.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Metaviromics of Namib Desert Salt Pans: A Novel Lineage of Haloarchaeal Salterproviruses and a Rich Source of ssDNA Viruses

Viruses, 2016
Viral communities of two different salt pans located in the Namib Desert, Hosabes and Eisfeld, were investigated using a combination of multiple displacement amplification of metaviromic DNA and deep sequencing, and provided comprehensive sequence data ...

Duckweeds under salt stress: a meta‐analysis of growth inhibition in relation to morphological and physiological traits and a systematic review of molecular responses

New Phytologist, EarlyView.
Salinity reduces duckweed growth responses. Summary Salinity is one of the main environmental factors limiting the performance of duckweeds and despite growing ecological and biotechnological interest in these macrophytes, there is a lack of quantitative analyses of their responses to sodium chloride.

The extreme halophilic archaeon Haloferax volcanii reduced Fe(III) to conserve energy from extracellular electron transfer

Journal of Bacteriology
Iron availability affects oceanic primary productivity and the strength of the biological carbon pump. However, the mechanism of iron solubility in hypersaline environments is poorly understood.
