This past week, we learned about different classifications of bacteria. One classification in particular was on which bacteria grow in certain temperature ranges. Listed below are four types of bacteria that we learned in class, in addition to an extra group:
- Psychrophiles can grow at 0° C but optimum is about 15° C.
- Psychrotrophs can grow at 0° C also but optimum is 20 - 30° C – (important in food spoilage).
- Mesophiles grow best at moderate around 37° C – (many pathogens fall in this category).
- Thermophiles have a growth optimum at around 60° C.
- Hyperthermophiles have growth optima of 80° C or higher.
