Expression of Recombinant Cold-Adapted (Hemo)Globins from Marine Bacteria
2022The production of recombinant proteins in bacteria made possible to obtain large quantities of proteins essential for basic and applied research. Escherichia coli remains one of the organisms of choice for recombinant proteins because of its ability to grow at high density and availability of a vast catalog of cloning vectors and mutant host strains ...

Aerobic biodegradation of nonylphenol by cold-adapted bacteria
Biotechnology Letters, 2003Three strains capable of mineralizing nonylphenol as sole carbon source were isolated from a sample of contaminated soil and characterized as two Pseudomonas spp. and a Stenotrophomonas sp. The two Pseudomonas spp. expressed characteristics typical of psychrophiles growing optimally of 10 degrees C and capable of growing at 0 degree C.

Temperature sensitivity of Antarctic soil‐humic substance degradation by cold‐adapted bacteria
Environmental Microbiology, 2021Summary Heteropolymer humic substances (HS) are the largest constituents of soil organic matter and are key components that affect plant and microbial growth in maritime Antarctic tundra. We investigated HS decomposition in Antarctic tundra soils from distinct sites by incubating samples at 5°C or 8°C (within a ...

Cold‐active enzymes from cold‐adapted bacteria
Journal of the American Oil Chemists' Society, 1997AbstractThe properties of amylase, lipase and protease, excreted by newly isolated bacteria from snow‐covered soil, salmon intestine and crab intestine, have been investigated. One amylase, one lipase, and three proteases have been characterized by shifts in their apparent optimal activities toward low temperatures and by reductions in their activation

Molecular Structure of Lipopolysaccharides of Cold-Adapted Bacteria
2017Cold-adapted Gram-negative bacteria inhabit snow, ice water, and frozen grounds and are perfectly adapted to live at very low temperatures. They have evolved several adaptation strategies, some of which concern the cellular membrane. Bacterial outer membrane, that functions as a selective barrier allowing the influx of nutrients and confers protection ...

Cold‐adapted bacteria for bioremediation of crude oil‐contaminated soil
Journal of Chemical Technology & Biotechnology, 2015AbstractBACKGROUNDThere are many cold climate terrestrial sites contaminated with petroleum hydrocarbons. Successful bioremediation in these regions relies heavily on suitable microorganisms with biodegrading capability at low temperatures. This work aims at screening cold‐adapted bacteria strains and examining their capability of biodegrading ...

Enhanced Bioremediation of Petroleum Contaminated Soils through Cold-adapted Bacteria
Petroleum Science and Technology, 2008Abstract The aim of this article is to develop an innovative microbial-enhanced aerobic bioremediation technique, which is viable within a western Canadian context where cold climate conditions exist. Soil samples from the petroleum contaminated Cantuar site, which is located in southwestern Saskatchewan, were picked up.

Biocatalysis and Agricultural Biotechnology, 2021
Abstract The Antarctic continent hosts heterogeneous regions, which are in general exposed to extreme conditions, mainly low temperatures. Thus, microorganisms that thrive in this environment are supposed to harbor a metabolic versatility of great biotechnological interest, which includes the production of cold-adapted enzymes.

Characterization of amylase produced by cold-adapted bacteria from Antarctic samples
Biocatalysis and Agricultural Biotechnology, 2020Abstract The Antarctic continent is characterized by extreme conditions and encompasses peculiar environments which represent promising habitats for the recovery of well-adapted microorganisms with unique metabolic capabilities. Enzymatic activity combined to salinity and pH tolerance of bacteria that thrive in low temperature environment have ...

Antimicrobial Potential of Cold-Adapted Bacteria and Fungi from Polar Regions
2016The discovery of novel and efficient antimicrobial compounds has become a focal point of interest for natural product chemistry. To this purpose, the exploration of unusual and underexplored sources of medically useful substances and the screening of less exploited microbial groups have been recognized as promising tools for the isolation of novel ...
