Biochemical tests to determine the biodegradability potential of bacterial strains in PAH polluted sites. B amino acid sequences of enzymes. 6 Citrate Utilization Test Aim To determine the ability of a microorganism to utilize citrate as the sole source of carbon and as energy source for the growth and ammonium salt as a sole source of nitrogen Principle Citrate test is used to differentiate among enteric bacteria on the basis of their ability to utilize ferment citrate.

Among the biochemical tests such as catalase test coagulase test starch h ydrolysis test and nitrate test are. Some of the biochemical tests mentioned here for example catalase test oxidase test assists us in many ways apart from the primary purpose mentioned in this post. In addition to the above tests the P.

Double test carried out in week 11-13. Phenol Red is ued as an indicator in the media. Particularly it is used to differentiate E.

Biochemical Test IMViC Significance of Biochemical Test IMViC. Used to identify the.

The biochemical tests in microbiology they are a set of chemical tests that are made to the microorganisms present in a sample in order to identify them. Lab Procedure We have included the basic procedure for doing many common biochemical tests below. Since bacteria will react differently to these tests it is much like the bacterial fingerprint.

D capability of a microbe to perform a specific enzymatic activity. D A genus can best be defined as. Intended Use The oxidase test is based on the production of an enzyme called indophenols oxidase.

B Amino acid sequences.
