Biochemical Tests for Streptococcus Organisms
Streptococcus organisms are Gram positive, microaerophilic and non-motile bacteria. There exist several sources of streptococcus organisms that include humans as well as many animal
Microbiology
Common Biochemical Tests in Microbiology: Hydrogen Sulphide Production Test
Some of the bacteria products hydrogen sulfide (H2S) gas mainly members of the family Enterobacteriaceae. The gas is produced when Sulphur containing amino acids like methionine
Common Biochemical Tests in Microbiology: Nitrate Reduction Test
Nitrate reduction test is used for differentiating organism on the basis of their capability to produce nitrate reductase enzyme that causes hydrolysis of nitrate to nitrite, which again depending
Common Biochemical Tests in Microbiology: Action on Litmus Milk
Milk is a very complicated source of nutrition that consists of protein in an aqueous solution of lactose and minerals. When bacteria are inoculated in this milk, the enzymes secreted by bacteria may bring about changes in the media. Litmus is added identify any changes in the pH.
Common Biochemical Tests in Microbiology: Voges-Proskauer’s Test
Voges-Proskauer’s test is named after two microbiologists after they observed a red colour reaction that was produced after a particular media was treated with potassium hydroxide.
Common Biochemical Tests in Microbiology: Utilization of Citrate as the Sole Source of Carbon
This test is among one of the biochemical test of IMViC tests which is used to differentiate to the gram-negative bacilli in the family Enterobacteriaceae.
Common Biochemical Tests in Microbiology: Gelatin Liquefaction Test
Gelatin is a type of protein obtained from animal protein collagen. The main use of gelatin is as a solidifying agent in food. The process of gelatin hydrolysis is used for determining bacteria proteolysis
Common Biochemical Tests in Microbiology: Methyl Red Test
Methyl-Red Test is one of the important biochemical test performed on bacterial species for studying about the ability of an organism to perform mixed acid fermentation from given glucose. It is a part of IMViC test.
Common Biochemical Tests in Microbiology: Indole Test
Indole test is one of the important biochemical test that is done on bacterial species for detection of organism’s capability to degrade the amino acid tryptophan and form indole.
To study the isolation of pure cultures by using pour plate method
The pour plate method is a common method for isolation of pure cultures and also for counting the number of microbial colonies. So, the objective of this method is to study how to isolate pure cultures by pour plate method.
