Deep- Sea Bacteria And Their Biotechnological Potentials [PDF]

, 2004
Deep-sea environment characterized by its low temperature, high hydrostatic pressure, limited nutrient contents, and constant darkness has been a hostile environment for most marine microorganisms.

Discovery and Characterization of a New Cold-Active Protease From an Extremophilic Bacterium via Comparative Genome Analysis and in vitro Expression

Frontiers in Microbiology, 2020
Following a screening of Antarctic glacier forefield-bacteria for novel cold-active enzymes, a psychrophilic strain Psychrobacter sp. 94-6PB was selected for further characterization of enzymatic activities.

Rye Snow Mold-Associated Microdochium nivale Strains Inhabiting a Common Area: Variability in Genetics, Morphotype, Extracellular Enzymatic Activities, and Virulence

Journal of Fungi, 2020
Snow mold is a severe plant disease caused by psychrophilic or psychrotolerant fungi, of which Microdochium species are the most harmful. A clear understanding of Microdochium biology has many gaps; the pathocomplex and its dynamic are poorly ...

The characterization of a new stabilized lactonase from the endophytic fungi Aspergillus pseudonomiae with anti‐bacterial and anti‐fungal properties

Protein Science, Volume 35, Issue 8, August 2026.
Abstract Microorganisms use diverse small‐molecule signals to coordinate behavior, supporting interspecies and interkingdom communication. These chemical dialogs shape fundamental biological processes and define interactions from cooperation to antagonism.

Aliivibrio wodanis as a production host: development of genetic tools for expression of cold-active enzymes

Microbial Cell Factories, 2019
Background Heterologous production of cold-adapted proteins currently represents one of the greatest bottlenecks in the ongoing bioprospecting efforts to find new enzymes from low-temperature environments, such as, the polar oceans that represent ...

Shewanella spp. genomic evolution for a cold marine lifestyle and in-situ explosive biodegradation. [PDF]

PLoS ONE, 2010
Shewanella halifaxensis and Shewanella sediminis were among a few aquatic gamma-proteobacteria that were psychrophiles and the first anaerobic bacteria that degraded hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX). Although many mesophilic or psychrophilic

Temperature and Ultraviolet Radiation Influence the Skin Microbiome of Humpback Whales

Molecular Ecology, Volume 35, Issue 15, August 2026.
ABSTRACT The skin microbiome of humpback whales harbours diverse microbial communities that play a crucial role in host skin protection and environmental interaction. However, studies on cetacean skin microbiomes in the Southern Hemisphere focus on feeding grounds, with limited information on microbiome dynamics at breeding grounds and during migration

Psychrophilic microorganisms and their cold-active enzymes

Journal of Industrial Microbiology & Biotechnology, 1996
The earth's vast and varied cold environments could be rich sources of psychrophilic microorganisms growing at 5°C or below. Unfortunately, the diversity, physiology and potential of these organisms have largely been overlooked. This article focuses on psychrophiles and their cold-active enzymes and emphasizes how future studies could give basic ...

Plasmids of psychrophilic and psychrotolerant bacteria and their role in adaptation to cold environments

Frontiers in Microbiology, 2014
Extremely cold environments are a challenge for all organisms. They are mostly inhabited by psychrophilic and psychrotolerant bacteria, which employ various strategies to cope with the cold.

Mechanozyme: An Artificial Enzyme With a Mechanophore Framework

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Mechanical destabilization of a G‐quadruplex mechanophore in a DNAzyme markedly boosts its catalytic activity, demonstrating “mechanozymes” as artificial enzymes whose functions are modulated by mechanical stress exerted by ultrasonication. This mechanozyme principle is broadly applicable to control biomolecular activities.
