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

open access: yesPhotosynthesis 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 ...

Protease Production from Polyextremophilic Bacteria

open access: yesInternational Journal of Current Microbiology and Applied Sciences, 2016
A B S T R A C T Extremophilic organisms which are capable of surviving in two different extreme environmental conditions simultaneously are known as polyextremophiles. These organisms are known to be potent producers of bioactive compounds namely enzymes such as proteases which are rapidly used in the growing industrial sector uses such as in the ...

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

open access: yesAstrobiology, 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

open access: yesBioMed 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

open access: yesBioMed 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.
