Why does bacteria grow better in heat?

Answer 1

they grow better in warm areas less than 140 degrees but more than 40 degrees. It is also that the heat causes the germ cells to multiply, causing more germ's. When people refer to bacteria growth it is actually about the amount of bacterium in a colony rather than the actual size of an individual bacterium increasing. Bacterium reproduce asexually through binary fission. This is when they basically just make a copy of their chromosome and then split. They reproduce sexually through conjunction. This is when they attach to one another using their pili, which are short hairlike structures on the outside of the cell. Heat causes this to happen more rapidly, causing more bacteria.
