High-Up: A Remote Reservoir of Microbial Extremophiles in Central Andean Wetlands [PDF]
The Central Andes region displays unexplored ecosystems of shallow lakes and salt flats at mean altitudes of 3700 m. Being isolated and hostile, these so-called “High-Altitude Andean Lakes” (HAAL) are pristine and have been exposed to little human ...

Development of an improved Pseudoalteromonas haloplanktis TAC125 strain for recombinant protein secretion at low temperature [PDF]
Background: In a previous paper, we reported the accomplishment of a cold gene-expression system for the recombinant secretion of heterologous proteins in Pseudoalteromonas haloplanktis TAC125.

Airborne bacterial populations above desert soils of the McMurdo Dry Valleys, Antarctica [PDF]
Bacteria are assumed to disperse widely via aerosolized transport due to their small size and resilience. The question of microbial endemicity in isolated populations is directly related to the level of airborne exogenous inputs, yet this has proven hard

Alkane hydroxylase genes in psychrophile genomes and the potential for cold active catalysis. [PDF]
BackgroundPsychrophiles are presumed to play a large role in the catabolism of alkanes and other components of crude oil in natural low temperature environments.

Cold adaptation strategy of psychrophilic bacteria: an in-silico analysis of isocitrate dehydrogenase [PDF]
Non-specific electrostatics is crucial for structure and stability; recently, it has been argued that psychrophilic proteins may also utilize specific electrostatic interactions. Do psychrophilic proteins increase the number of salt bridges for cold adaptation?

RNA interference in marine and freshwater sponges [PDF]
Background: The marine sponge Tethya wilhelma and the freshwater sponge Ephydatia muelleri are emerging model organisms to study evolution, gene regulation, development, and physiology in non-bilaterian animal systems. Thus far, functional methods (i.e.,

Potentials and limitations of cold-adapted hydrogen producing bacteria: A mini review
Low-temperature bacteria have potential to produce biohydrogen and are often considered a potential renewable energy generator for the future. However, the bacteria have presented poor hydrogen yield due to slow metabolic rate and prolonged lag phase often caused by their restricted growth temperature limit.
