How does temperature affect bioremediation?

• It has no effect on the process

• Higher temperatures increase microbial activity

• Lower temperatures increase microbial activity

• Temperature only affects the pH level

What is the pH of the soil?

• It has no impact on microbial metabolism

• It affects the growth of plants

• pH is not related to bioremediation

• It influences the biodegradation process
