agulation of proteins is a test in biochemistry to find whether there are proteins such as albumin and globulin found in proteins. The coagulation of proteins in reaction the heat stimulus is an typical phenomenon. The process of coagulation by heat of proteins happens in two phases; denaturation or Agglutination, or the dissociation of the protein denatured in the form it is in.

IMViC is a mnemonic that stands for four tests used in the identification of enteric bacteria: Indole, Methyl Red, Voges-Proskauer, and Citrate. These tests are commonly used in microbiology laboratories to identify bacterial species in the Enterobacteriaceae family, which includes many common pathogens such as Escherichia coli and Salmonella. The principle behind the IMViC tests … Read more

Alkaline Phosphatase (ALP) is an enzyme that is naturally found within all the raw milks that is utilized to determine the quality of pasteurization of milk. A complete pasteurization process can deactivate the enzyme below levels that can be detected by traditional methods. Because the stability of the heat of ALP is higher than the stability of pathogens that could be found in milk, it serves as a metric of security. However, failure for detection of ALP activity is not a mean an item is safe from pathogens.
