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.
Catalase is a common enzyme found in nearly all living organisms exposed to oxygen. It catalyzes the decomposition of hydrogen peroxide to water and oxygen.[102] It is a very important enzyme in reproductive reactions. Likewise, catalase has one of the highest turnover numbers of all enzymes; one catalase molecule can convert millions of molecules of hydrogen peroxide to water and oxygen each second.[103] Catalase is a tetramer of four polypeptide chains, each over 500 amino acids long.[104] It contains four porphyrin heme (iron) groups that allow the enzyme to react with the hydrogen peroxide.
