Question

Would a microbe that tested positive for a catalase test likely engage in aerobic or anaerobic metabolism? Why?

Answer 1

Catalase test is the process in which we have differentiate a microbes such as bacteria (staphylococcus) is catalase positive or catalase negative. In this test used a enzyme catalase which is produce by a bacteria that bacteria is respire using oxygen and protect themself from the toxic oxygen product.

Catalase test is responsible for aerobic metabolism because it is very important enzyme to protecting the cell from oxidative damage it's break the hydrogen peroxide decomposition to water and oxygen.
