Restriction enzymes are found in many different strains of bacteria where their biological role is to participate in cell defense. These enzymes restrict foreign (viral) DNA that enters the cells by destroying them.
Yeasts will grow over a temperature range of 10°-37°C (50°-98.6°F), with an optimal temperature range of 30°-37°C (86°-98.6°F), depending on the type of species. There is little activity in the range of 0°-10°C. Above 37°C yeast cells become stressed and will not divide properly. Most yeast cells die above 50°C (122°F).
