Computer simulations explain the anomalous temperature optimum in a cold-adapted enzyme
Nature Communications, 2020 Enzymes from organisms inhabiting cold environments (psychrophiles) have adapted to catalyzing chemical reactions at near freezing temperatures. Here – using molecular dynamics simulations – the authors analyze cold adaptation of psychrophilic α-amylase ...

Isolation of carotenoid-producing yeasts from an alpine glacier [PDF]
, 2014 Cold-adapted yeasts are increasingly being isolated from glacial environments, including Artic, Antarctic, and mountain glaciers. Psychrophilic yeast isolates mostly belong to Basidiomycota phylum, such as Cryptococcus, Mrakia, and Rhodotorula, and ...

Psychrophilic Lipase from Arctic Bacterium
Tropical Life Sciences Research, 2016 A lipase producer psychrophilic microorganism isolated from Arctic sample was studied. The genomic DNA of the isolate was extracted using modified CTAB method. Identification of the isolate by morphological and 16S rRNA sequence analysis revealed that the isolate is closely related to Arthrobacter gangotriensis (97% similarity). A.

Extremophiles and their application to veterinary medicine
Irish Veterinary Journal, 2004 Extremophiles are organisms that can grow and thrive in harsh conditions, e.g., extremes of temperature, pH, salinity, radiation, pressure and oxygen tension. Thermophilic, halophilic and radiation-resistant organisms are all microbes, some of which are

Response of selected microoganisms to experimental planetary environments [PDF]
A microbial population profile of mixed Cape Canaveral soil samples is presented. During this investigation a few organisms were isolated which exhibit the ability to grow at 3 C, 32 C, and 55 C.

Degradation of Dispersants and Dispersed Oil [PDF]
, 2011 Chemical oil dispersants are proprietary mixtures of surfactants and solvents which are directly applied to a spill in order to reduce the natural attractive forces of the oil. When oil treated with dispersants is exposed to mixing energy, typically from

Microbial Extremophiles in Evolutionary Aspect [PDF]
, 2007 The microflora of the cryosphere of planet Earth provides the best analogs for life forms that might be found in the permafrost or polar ice caps of Mars, near the surface of the cometary nuclei, or in the liquid water beneath the ice crusts of icy moons
