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.
Growth from an overnight culture of the microbe is smeared on a microscope slide. A drop of 3% hydrogen peroxide is added. If copious bubbles are observed, the microbe is positive for catalase.atalase is then added and the reaction is observed. To view the catalase test in VirtualUnknown â¢ Microbiology, complete the following steps: 2. Press the Play button to watch the video. A short video clip showing microscopic observation of a catalase test for the unknown organism will play.
