Gram-Sure Test is a rapid qualitative diagnostic test used for the differentiation of aerobic Gram-negative and Gram-positive bacteria. It is mainly applied for bacteria that are rods or coccobacilli in shape. This test works by detecting the presence of a specific enzyme known as L-alanine aminopeptidase. This enzyme is present almost exclusively in Gram-negative bacterial … Read more
It is a biochemical test used in microbiology for the identification of Streptococcus pneumoniae from other alpha hemolytic streptococci. It is mainly based on the ability of pneumococcal cells to undergo lysis in presence of bile salts. This test is commonly performed in diagnostic laboratories for confirmation of pneumococcal isolates. It is the process in … Read more
Leucine aminopeptidase (LAP) is an enzyme used to distinguish catalase-negative, gram-positive cocci of Aerococcus and Leuconostoc (LAP test negative) from other organisms in the group, such as Streptococcus, Enterococcus, Lactococcus, and Pediococcus (almost always positive).
It is a biochemical test that is used to determine the ability of microorganism to produce and secrete the enzyme lipase. It is also referred to as lipase test. The complex lipids such as triglycerides are large molecules and these cannot pass through the bacterial cell membrane. Due to this reason some bacteria releases the … Read more
A lipase test is a laboratory diagnostic test which is done to measure the level of lipase enzyme in the blood. Lipase is a digestive enzyme which is mainly produced by pancreas and it helps in digestion of fats. It is the process in which dietary triglycerides are broken down into fatty acids and glycerol … Read more
The purpose of the malonate test is to see if the organism can get all of its energy from malonate.
The oxidase enzyme is a key factor in distinguishing Staphylococcus from Micrococcus, and the Microdase Disk is a reagent-impregnated disc recommended for use in qualitative procedures.
What is API (Analytical Profile Index) 20E Test? The API (Analytical Profile Index) 20E test is a standardized biochemical identification system used for the identification of Enterobacteriaceae and other non-fastidious Gram-negative rods. It is developed as a miniaturized system where a number of biochemical reactions are carried out simultaneously in a single plastic strip. It … Read more
