Recent Progress on Methods for the Detection and Analysis of Psychrophilic Bacteria in Milk [PDF]
Shipin KexueMilk is an excellent medium for the growth of microorganisms, which is easily contaminated by microorganisms from the environment. Psychrophilic bacteria are the most common microorganisms in cold-stored raw milk. Moreover, psychrophilic bacteria produce

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 ...

Comparison of the white-nose syndrome agent Pseudogymnoascus destructans to cave-dwelling relatives suggests reduced saprotrophic enzyme activity. [PDF]
PLoS ONE, 2014 White-nose Syndrome (WNS) is an emerging infectious mycosis that has impacted multiple species of North American bats since its initial discovery in 2006, yet the physiology of the causal agent, the psychrophilic fungus Pseudogymnoascus destructans ...

Psychrophiles: Ecological significance and potential industrial application
South African Journal of Science, 2018 The bulk of earth’s biosphere is cold (5 °C) that sustains a broad diversity of microbial life by triggering physiological response(s) to ensure survival in cold and frozen ecosystems.
