How does temperature affect bacterial growth?

Answer 1

Most microbes, such as bacteria and yeast, have an optimal temperature range in which they grow best. If you get either too low or too high then they grow much slower and finally cease growing at all. However this temperature range can vary with different organisms. The main reason is the ability of the enzymes that catalyze all the biochemical reactions in the yeast cell to function at those temperatures. Enzymes have an optimal temperature range. When you get below that range there ability to catalyze the intended reaction really slows down. Above that temperature and the enzyme begins to denature or unfold and becomes inactive. Each enzyme will have a different range where it becomes inactive. (this probably all sounds really confusing but it can be help full for last minute revision, it also tends to impress teachers too!)xxx

Answer 2

Certain organisms, like humans or cats or bacteria, have been created to live and thrive in certain temperature ranges. For example, the bacteria that causes Botulism (C.Botulinum) will die at temperatures exceeding 250 degrees F, but will thrive at more milder temperatures, like room temperature for example. While other bacteria will thrive at higher temperatures.

Answer 3

bacteria multiply s and grows quicker when warmer
