WebJun 18, 2024 · Their temperature range lies between 20 0 C to 45 0 C. The optimum temperature of a mesophile is 37 0 C. Mesophilic bacteria are considered to be the best decomposers in the soil. They are also involved in food contamination and degradation. Most microorganisms found in the human intestine are mesophiles. 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.
