Singular adaptations in the carbon assimilation mechanism of the polyextremophile cyanobacterium Chroococcidiopsis thermalis

Photosynthesis Research, 2023
Abstract Cyanobacteria largely contribute to the biogeochemical carbon cycle fixing ~ 25% of the inorganic carbon on Earth. However, the carbon acquisition and assimilation mechanisms in Cyanobacteria are still underexplored regardless of being of great importance for shedding light on the origins of autotropism ...

CULTIVATION CONDITIONS FOR PROTEASE PRODUCTION BY A THERMO-HALOSTABLE BACTERIAL ISOLATE PLS A

Jurnal Natural, 2019
Polyextremophiles have increasingly been utilised to produce thermostable enzymes with better stability in multiple extreme conditions. This study reports the screening results of four new bacterial isolates (PLS A, PLS 75, PLS 76 and PLS 80), isolated ...

An Antarctic Extreme Halophile and Its Polyextremophilic Enzyme: Effects of Perchlorate Salts [PDF]

Astrobiology, 2018
Effects of perchlorate salts prevalent on the surface of Mars are of significant interest to astrobiology from the perspective of potential life on the Red Planet. Halorubrum lacusprofundi, a cold-adapted halophilic Antarctic archaeon, was able to grow anaerobically on 0.04 M concentration of perchlorate.

Polyextremophilic Bacteria from High Altitude Andean Lakes: Arsenic Resistance Profiles and Biofilm Production

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
High levels of arsenic present in the High Altitude Andean Lakes (HAALs) ecosystems selected arsenic‐resistant microbial communities which are of novel interest to study adaptations mechanisms potentially useful in bioremediation processes. We herein performed a detailed characterization of the arsenic tolerance profiles and the biofilm production of ...

Identification of a New Serine Alkaline Peptidase from the Moderately Halophilic Virgibacillus natechei sp. nov., Strain FarDT and its Application as Bioadditive for Peptide Synthesis and Laundry Detergent Formulations

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
A new peptidase designated as SAPV produced from a moderately halophilic Virgibacillus natechei sp. nov., strain FarDT was investigated by purification to homogeneity followed by biochemical and molecular characterization purposes. Through optimization, it was determined that the optimum peptidase activity was 16,000 U/mL.

Genome‐Scale Metabolic Modeling of Archaea Lends Insight into Diversity of Metabolic Function

Archaea, Volume 2017, Issue 1, 2017., 2017
Decades of biochemical, bioinformatic, and sequencing data are currently being systematically compiled into genome‐scale metabolic reconstructions (GEMs). Such reconstructions are knowledge‐bases useful for engineering, modeling, and comparative analysis. Here we review the fifteen GEMs of archaeal species that have been constructed to date.

Comparative Genome Analysis of Three Halobacillus Strains Isolated From Saline Environments Reveal Potential Salt Tolerance and Algicidal Mechanisms

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Following the previous complete genome analysis, this research provides the function of new Halobacillus species. Three strains were identified: Halobacillus shinanisalinarum sp. nov. SSTM10‐2T, Halobacillus salinarum sp. nov. SSBR10‐3T, and Halobacillus amylolyticus sp. nov. SSHM10‐5T.
