Psychrotrophic microbes are able to grow at temperatures below 7 °C (44.6 °F), but have better growth rates at higher temperatures. Psychrotrophic bacteria and fungi are able to grow at refrigeration temperatures, and can be responsible for food spoilage and as foodborne pathogens such as Yersinia. They provide an estimation of the product's shelf life, but also they can be found in soils, in surface and deep sea waters, in Antarctic ecosystems, and in foods. small 4 wheel drive suv 2017WebDec 31, 2024 · Psychrophiles are extremophilic bacteria or archaea which are cold-loving having an optimal temperature for growth at about 15°C or lower, a maximal temperature for growth at about 20°C and... small 4th of july flagWebMay 31, 2024 · What temperature do psychrophiles grow best?
