This is a short video on the biochemical tests used for college microbiology classes part 1 series of basics biochemical tests used in microbiology labs. Biochemical tests there are many biochemical tests that can be used to help identify bacteria since bacteria will react differently to these tests it is much like the bacterial fingerprint. Biochemical tests are the quickest and easiest tests for identifying bacteria because they use deductive principles to reduce the number of possible species present very quickly additionally, because bacteria are microorganisms, visual identification is not always possible, and is never easy.
