Industrial applications of cold-adapted enzymes: challenges, innovations and future perspective

3 Biotech, 2021
Extreme cold environments are potential reservoirs of microorganisms producing unique and novel enzymes in response to environmental stress conditions. Such cold-adapted enzymes prove to be valuable tools in industrial biotechnology to meet the increasing demand for efficient biocatalysts.

Cold-Active Enzymes from Cold-Adapted Yeasts

2017
Cold-adapted yeasts include psychrophiles or psychrotolerant nonconventional species able to survive and grow at low temperatures. They represent an important source of biological diversity that has developed a set of structural and functional adaptation strategies to overcome the adverse effects of cold (sometimes associated with other limiting ...

Hydrocarbon degradation and enzyme activities of cold-adapted bacteria and yeasts

Extremophiles, 2003
The potential of 89 culturable cold-adapted isolates from uncontaminated habitats, including 61 bacterial and 28 yeast strains, to utilize representative fractions of petroleum hydrocarbons (n-alkanes, monoaromatic and polycyclic aromatic hydrocarbons) for growth and to produce various enzymes at 10 degrees C was investigated.

Cold‐active enzymes from cold‐adapted bacteria

Journal of the American Oil Chemists' Society, 1997
AbstractThe 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

Biotechnology of enzymes from cold-adapted microorganisms

1999
One of the main goals in enzyme research is industrial application. Nowadays, we are surrounded by enzymes as well as chemicals produced by enzymes in our daily life. Since papain (EC 3.4.22.2) was used, probably as the first exogenous enzyme, to prevent the formation of chill hazes in beer,1 many enzymes isolated from various species have been ...

Harnessing the Untapped Potential of Cold-Adapted Enzymes

Industrial Biotechnology
Cold-adapted enzymes exhibit high catalytic activity at low temperatures and specificity, making them ideal biocatalysts for various industrial applications. Their thermolability facilitates easy inactivation under mild conditions, preventing excessive enzymatic activity.

Isolation and characterization of psychrophilic yeasts producing cold-adapted pectinolytic enzymes

Letters in Applied Microbiology, 2004
The present study was conducted to screen for psychrophilic yeasts that are able to degrade pectin compounds at low temperature, and to examine the cold-active pectinolytic enzymes produced by the isolated psychrophilic yeasts.Psychrophilic yeasts, which grow on pectin as a sole carbon source, pectinolytic-psychrophilic yeast (PPY) strains PPY-3, 4, 5 ...

Cold adaption of enzymes: Structural comparison between salmon and bovine trypsins

Proteins: Structure, Function, and Bioinformatics, 1994
AbstractThe crystal structure of an anionic form of salmon trypsin has been determined at 1.82 Å resolution. We report the first structure of a trypsin from a phoikilothermic organism in a detailed comparison to mammalian trypsins in order to look for structural rationalizations for the cold‐adaption features of salmon trypsin.

Molecular dynamics of the salt dependence of a cold-adapted enzyme: endonuclease I

Journal of Biomolecular Structure and Dynamics, 2015
The effects of salt on the stability of globular proteins have been known for a long time. In the present investigations, we shall focus on the effect of the salt ions upon the structure and the activity of the endonuclease I enzyme. In the present work, we shall focus on the relationship between ion position and the structural features of the Vibrio ...

Metabolism, enzymic activities and cold adaptation in Antarctic mesopelagic fishes

Marine Biology, 1988
Several species of Antarctic mesopelagic fishes that have different minimal depths of occurrence but the same environmental temperature were collected in November–December 1983 and in March 1986 between 0 and 1 000 m in the open water near the marginal ice zone in the vicinity of 60°S 40°W (1983) and 65°S 46°W (1986), and oxygen consumption rate (V O 2)
