Résumé

Among the very large diversity of micro-organisms, some are capable of surviving and proliferating at low temperatures. These micro-organisms, called psychrotrophs, are widely distributed and include various genera of bacteria, moulds and yeasts. Psychrotrophs are defined as organisms capable of growing at or close to zero, having optimal growth at temperatures of 15 °C or more and upper limits as high as 40 °C in a few cases. Most of the micro-organisms that are capable of growth in food held at 5 °C are bacteria which grow optimally at 25-30 °C. Although most of these bacteria cause spoilage, certain species are foodborne pathogens. Some information is given concerning these bacteria and their proteins.
