Psychrotrophic bacteria are those that can grow in low temperatures. Some species have been known to survive at zero degrees Celsius or lower, but most have an optimum growing temperature between 10 and 20 degrees Celsius.
Multiplying at low temperatures is a cause for concern when it comes to food, as the cooler climate of the refrigerator will not work in preventing these microbes from growing. L. piscium is one of the most common of all food-spoiling bacteria found in fridge-stored products. It mainly targets meat, giving it a sour smell.
