LAP test is used for the differentiation and identification of catalase-negative Gram-positive cocci bacteria. Specifically, it is used to distinguish Streptococcus, Enterococcus, Pediococcus, and Lactococcus species from Aerococcus and Leuconostoc … Read more
Lipid Hydrolysis Test (Lipase Test) is the biochemical test used to detect the ability of bacteria to produce exoenzyme lipase and hydrolyze lipids. Lipids are important components of the biological … Read more
Lecithinase Test (Nagler’s Reaction) is a biochemical test for assessing bacteria’s ability to produce a toxic, phospholipase enzyme called ‘lecithinase’. Lecithinase (Phospholipase C) is a lipolytic enzyme, produced by some … Read more
Casein Hydrolysis Test is the biochemical test used to determine the ability of bacteria to synthesize caseinase enzyme. Casein is the major protein (phosphoprotein) with a molecular formula of C81H125N22O39P, … Read more
Carbohydrate Fermentation Test is the biochemical test used to assess the ability of bacteria to ferment a specific carbohydrate and to differentiate bacteria based on their carbohydrate fermentation pattern and … Read more
KOH test, also known as KOH mount or KOH preparation, is a rapid test used to visualize the fungal structures in clinical samples using potassium hydroxide (KOH) as a clearing … Read more
Hydrogen Sulfide (H2S) Test is the biochemical test used to detect the ability of bacteria to produce H2S gas. Several bacteria and archaea can metabolically reduce sulfur-containing compounds to hydrogen … Read more
Different bacteria have different enzyme systems and different biochemical activities to derive metabolic energy. Based on the enzyme system and biochemical characteristics, the end product of metabolism of the same … Read more
Pyruvate Broth Test is the biochemical test used to assess the ability of bacteria to utilize pyruvate and produce metabolic acid. Two pyruvates are produced as end products during glycolysis (aerobic … Read more
Salt Tolerance Test is the biochemical test used to determine the ability of bacteria to tolerate a high salt concentration (of 6.5%). Different genera of bacteria have different requirements for … Read more
