Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes

FEBS Letters, EarlyView.
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Performance of the edible halophyte Cakile maritima under critical magnesium and potassium thresholds

Journal of Oasis Agriculture and Sustainable Development
In their natural biotope, plants are challenged with low nutrient availability which is one of the most important limiting factors for plant production. Nutrient limitation causes disruption in several metabolic pathways resulting in a decrease in plant

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics

FEBS Open Bio, EarlyView.
Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

Communities that thrive in extreme conditions captured from a freshwater lake [PDF]

, 2016
Organisms that can grow in extreme conditions would be expected to be confined to extreme environments. However, we were able to capture highly productive communities of algae and bacteria capable of growing in acidic (pH 2), basic (pH 12) and saline (40

The pyruvate:ferredoxin oxidoreductase of the thermophilic acetogen, Thermoanaerobacter kivui

FEBS Open Bio, 2021
Pyruvate:ferredoxin oxidoreductase (PFOR) is a key enzyme in bacterial anaerobic metabolism. Since a low‐potential ferredoxin (Fd2−) is used as electron carrier, PFOR allows for hydrogen evolution during heterotrophic growth as well as pyruvate synthesis

An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide

Advanced Materials, EarlyView.
Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

A single amino-acid substitution in the sodium transporter HKT1 associated with plant salt tolerance [PDF]

, 2017
A crucial prerequisite for plant growth and survival is the maintenance of potassium uptake, especially when high sodium surrounds the root zone. The Arabidopsis HIGH-AFFINITY K TRANSPORTER1 (HKT1), and its homologs in other salt-sensitive dicots ...

Suppressing Glycerol‐3‐phosphate Phosphatase and Enhancing Glycerol‐3‐Phosphate Shuttle Flux Crucial for High‐Efficiency Fatty Acid Production in the Fast‐Growing Oleaginous Schizochytrium

Advanced Science, EarlyView.
This study establishes an efficient oleaginous heterotrophic microalga, Schizochytrium, through chassis optimization and metabolic engineering, significantly enhancing fatty acid titers and productivities. It also identifies a regulatory mechanism that coordinates biomass and lipid synthesis, providing a rational target for metabolic pathway rewiring ...
