A
Temperature
B
Nutrient concentration
C
pH
D
Osmotic pressure
Verified step by step guidance1
Understand that incubators are devices designed to create controlled environmental conditions to support microbial growth.
Identify the factors that influence microbial growth: temperature, nutrient concentration, pH, and osmotic pressure.
Recognize that incubators primarily control temperature by maintaining a constant and optimal heat level for microbial metabolism and reproduction.
Note that nutrient concentration is controlled by the composition of the growth medium, not by the incubator itself.
Understand that pH and osmotic pressure are also properties of the growth medium and environment, which are not directly regulated by incubators.
