MISS diversity from saline lakes of Brazilian Pantanal: Origin, potential of preservation and comparison with examples of the Ediacaran‐Cambrian shallow depositional settings

Sedimentology, Volume 73, Issue 4, Page 945-964, June 2026.
ABSTRACT One of the largest wetlands on Earth, the Brazilian Pantanal contains roughly 10 000 natural lakes, about 1000 of which are hypersaline. In these environmentally stressful settings, animal life struggles to survive, while cyanobacteria form extensive mats.

Bacterial sigma factors as targets for engineered or synthetic transcriptional control

Frontiers in Bioengineering and Biotechnology, 2014
Sigma (σ) factors are the predominant constituents of transcription regulation in bacteria. σ factors recruit the core RNA polymerase (RNAP) to recognize promoters with specific DNA sequences. Recently engineering of transcriptional regulators has become

The Complete Genome Sequence of Thermococcus onnurineus NA1 Reveals a Mixed Heterotrophic and Carboxydotrophic Metabolism

, 2008
Members of the genus Thermococcus, sulfur-reducing hyperthermophilic archaea, are ubiquitously present in various deep-sea hydrothermal vent systems and are considered to play a significant role in the microbial consortia.

Eco‐Friendly and Economical Approach for Immobilization of Thermostable ω‐Transaminase

Chemistry–Methods, Volume 6, Issue 5, May 2026.
This work presents immobilization of thermostable ω‐Transaminase on diatomaceous earth using eco‐friendly Fe3+‐tannic acid complexes. The immobilized enzyme retains optimal activity and preserves over half its activity after repeated cycles, offering a simple, economical immobilization strategy for industrial biocatalysis.

Biomolecules from extremophile microalgae: From genetics to bioprocessing of a new candidate for large-scale production

, 2019
Extremophile microalgae are potential candidates for large-scale production because the extreme growth conditions help avoiding contamination, especially in open pond reactors.

Biotechnology for mechanisms that counteract salt stress in extremophile species: A genome-based view

, 2013
Molecular genetics has confirmed older research and generated new insights into the ways how plants deal with adverse conditions. This body of research is now being used to interpret stress behavior of plants in new ways, and to add results from most ...

The resistance of the lichen Circinaria gyrosa (nom. provis.) towards simulated Mars conditions—a model test for the survival capacity of an eukaryotic extremophile

, 2012
The “Planetary Atmospheres and Surfaces Chamber” (PASC, at Centro de Astrobiología, INTA, Madrid) is able to simulate the atmosphere and surface temperature of most of the solar system planets.
