What is the difference between mesophilic and thermophilic culture?

by Kim

Mesophilic means medium-temperature loving bacteria which will ferment the best at temperatures up to 30°C or 90°F.

Thermophilic is a heat-loving bacteria which will ferment best when above 30°C or 90°F.

Different cheeses require different temperatures during the process, and therefore different cultures are used to provide different textures and tastes across the range of cheeses.
