Pretty much like beef. It's relatively common in India where beef is not eaten for religious reasons. You can also find it without much trouble in both Egypt and Italy. I suspect that in SE Asia, where water buffalo are common, it's also widely eaten.
The inadvertent use of a mixed culture in. biochemical testing will lead to erroneous results. The simplest biochemical test that is used to differentiate between Streptococcus and. Staphylococcus species is the Catalase test. In this test we are testing for the ability of the. bacteria to produce the enzyme catalase. This enzyme breaks down hydrogen peroxide into. water and oxygen. Hydrogen peroxide, as well as superoxides, can be metabolic end. products of the production of ATP by the electron transport chain.
The catalase enzyme is so critical to our health that it is found in nearly every living organism on the planet that is exposed to oxygen. This antioxidant enzyme can catalyze the conversion of hydrogen peroxide into water and oxygen. Hydrogen peroxide is a by-product of cell metabolism, which serves some useful functions including healthy immune response. Catalase has one of the highest rates of turnover when compared to all other enzymes. In other words, one catalase enzyme can change 40 million molecules of hydrogen peroxide into water and oxygen in just one second.
