Improving confirmed nanometric sulfur bioproduction using engineered Thioalkalivibrio versutus

, 2020
Complicated production procedures and superior characteristics of nano-sized sulfur elevate its price to 25-40 fold higher than micrograde kind. Also, natural gas hydrogen sulfide levels are restricted because of its toxic environmental consequences ...

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.

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.

Determination of the Residual Anthracene Concentration in Cultures of Haloalkalitolerant Actinomycetes by Excitation Fluorescence, Emission Fluorescence, and Synchronous Fluorescence: Comparative Study

Journal of Analytical Methods in Chemistry, Volume 2016, Issue 1, 2016., 2016
Polycyclic aromatic hydrocarbons (PAHs) are compounds that can be quantified by fluorescence due to their high quantum yield. Haloalkalitolerant bacteria tolerate wide concentration ranges of NaCl and pH. They are potentially useful in the PAHs bioremediation of saline environments.

Genomic features of lichen‐associated black fungi

IUBMB Life, Volume 77, Issue 1, January 2025.
Abstract Lichens are mutualistic associations consisting of a primary fungal host, and one to few primary phototrophic symbiont(s), usually a green alga and/or a cyanobacterium. They form complex thallus structures, which provide unique and stable habitats for many other microorganisms. Frequently isolated from lichens are the so‐called black fungi, or

Purification and Characterization of a Polyextremophilic α‐Amylase from an Obligate Halophilic Aspergillus penicillioides Isolate and Its Potential for Souse with Detergents

BioMed Research International, Volume 2015, Issue 1, 2015., 2015
An extracellular α‐amylase from the obligate halophilic Aspergillus penicillioides TISTR3639 strain was produced and enriched to apparent homogeneity by ammonium sulfate precipitation and Sephadex G100 gel filtration column chromatography. The mass of the purified amylase was estimated to be 42 kDa by SDS‐PAGE.

Characterization of Skoliomonas gen. nov., a haloalkaliphilic anaerobe related to barthelonids (Metamonada)

Journal of Eukaryotic Microbiology, Volume 71, Issue 6, November/December 2024.
Abstract Metamonads are a large and exclusively anaerobic group of protists. Additionally, they are one of the three clades proposed to ancestrally possess an “excavate” cell morphology, with a conspicuous ventral groove accompanied by a posterior flagellum with a vane.

Archaeal Communities in a Heterogeneous Hypersaline‐Alkaline Soil

Archaea, Volume 2015, Issue 1, 2015., 2015
In this study the archaeal communities in extreme saline‐alkaline soils of the former lake Texcoco, Mexico, with electrolytic conductivities (EC) ranging from 0.7 to 157.2 dS/m and pH from 8.5 to 10.5 were explored. Archaeal communities in the 0.7 dS/m pH 8.5 soil had the lowest alpha diversity values and were dominated by a limited number of ...

Characterization of novel mevalonate kinases from the tardigrade Ramazzottius varieornatus and the psychrophilic archaeon Methanococcoides burtonii

Acta Crystallographica Section D, Volume 80, Issue 3, Page 203-215, March 2024.
This work reports the purification, biochemical characterization and high‐resolution structures of two novel mevalonate kinases: one from the extremotolerant tardigrade Ramazzottius varieornatus at 2 Å resolution and one from the psychrophilic archaeon Methanococcoides burtonii at 2.2 Å resolution.Mevalonate kinase is central to the isoprenoid ...
