Haloarchaea: A Promising Biosource for Carotenoid Production

2021
Haloarchaea are halophilic microorganisms belonging to the Archaea domain that inhabit salty environments (mainly soils and water) all around the world. Most of the genera included in this group are able to produce carotenoids at significant concentrations (even wild-type strains).

Genomics and functional genomics with haloarchaea

Archives of Microbiology, 2008
The first haloarchaeal genome was published in 2000 and today five genome sequences are available. Transcriptome and proteome analyses have been established for two and three haloarchaeal species, respectively, and more than 20 studies using these functional genomic approaches have been published in the last two years.

Carotenoids from Haloarchaea: Extraction, Fractionation, and Characterization

2022
Carotenoids are bioactive molecules known to promote human health. Many extreme halophilic archaea synthesize carotenoids, mainly represented by C50 bacterioruberin (BR) and its derivatives. BR has a potent antioxidant capacity, even higher than that of β-carotene, thus, there is an increasing interest to advance the study of its biological properties ...

Haloarchaea, excellent candidates for removing pollutants from hypersaline wastewater

Trends in Biotechnology, 2022
Hypersaline wastewater is difficult to treat due to the inhibition of salt stress on microbes' viability and metabolic capabilities. Haloarchaea, native microorganisms that thrive in hypersaline habitats, overcome this key obstacle naturally. This review provides a comprehensive overview of the metabolic versatility of Haloarchaea in hypersaline ...

Haloarchaea: worth exploring for their biotechnological potential

Biotechnology Letters, 2017
Halophilic archaea are unique microorganisms adapted to survive under high salt conditions and biomolecules produced by them may possess unusual properties. Haloarchaeal metabolites are stable at high salt and temperature conditions that are useful for industrial applications.

Anaerobic carboxydotrophy in sulfur-respiring haloarchaea from hypersaline lakes

The ISME Journal, 2022
Abstract Anaerobic carboxydotrophy is a widespread catabolic trait in bacteria, with two dominant pathways: hydrogenogenic and acetogenic. The marginal mode by direct oxidation to CO2 using an external e-acceptor has only a few examples. Use of sulfidic sediments from two types of hypersaline lakes in anaerobic enrichments with CO as an ...

Isolation of haloarchaea that grow at low salinities

Environmental Microbiology, 2004
Summary Archaea, the third domain of life, were long thought to be limited to environmental extremes. However, the discovery of archaeal 16S rRNA gene sequences in water, sediment and soil samples has called into question the notion of Archaea as obligate extremophiles.

Evolutionary Developmental Biology in Haloarchaea

2023
Archaea as one of the three domains of life are prokaryotes that are similar to bacteria, yet have distinct properties that separate them from Bacteria and Eukaryota. Most archaea and bacteria cells are similar in shape and size, but there are exceptions like the Haloquadratum walsbyi, which has flat and square-shaped cells. Archaea are the predominant
