Triple Sugar Iron (TSI) Agar

Triple Sugar Iron (TSI) Agar

Triple Sugar Iron (TSI) Agar Most bacteria have the ability to ferment carbohydrates, particularly sugars. Among them, each bacterium can ferment only some of the sugars, while it cannot ferment the others. Thus, the sugars, which a bacterium can ferment and the sugars, which it cannot is the characteristic of the bacteria and thus an … Read moreTriple Sugar Iron (TSI) Agar

Heme Degradation

Heme Degradation

Heme Degradation Hemes are cyclic tetrapyrroles that contain iron and are commonly found as the prosthetic group of hemoglobin, myoglobin and the cytochromes. This small-molecule component of globins, critical for oxygen transport among other functions undergo a complex process of metabolism and degradation. Roughly 80% of heme destined for degradation and excretion comes from senescent … Read moreHeme Degradation

Violet Red Bile Agar (VRBA)

Violet Red Bile Agar (VRBA)

Violet Red Bile Agar (VRBA) Coliforms refer to all aerobic and facultative anaerobic, gram-negative, non-spore-forming rod-shaped bacteria that ferment lactose with gas and acid formation within 48 hours at 35°C. Procedures to detect, enumerate, and presumptively identify coliforms are used in testing foods and dairy products. One method for performing the presumptive test for coliforms … Read moreViolet Red Bile Agar (VRBA)

Membrane Carbohydrate

Membrane Carbohydrate Structure

Membrane Carbohydrate Cell membranes are selective barriers that separate individual cells and cellular compartments. Membranes are assemblies of carbohydrates, proteins, and lipids held together by binding forces. Carbohydrates are covalently linked to proteins (glycoproteins) or lipids (glycolipids) and also an important part of cell membranes, and function as adhesion and address loci for cells. The Fluid Mosaic Model describes membranes as a … Read moreMembrane Carbohydrate

Levinthal’s Medium

Levinthal’s Medium

Levinthal’s Medium The genus Haemophilus includes a number of species that cause a wide variety of infections but share a common morphology and a requirement for blood-derived factors during growth that has given the genus its name. The Haemophilus genus represents a large group of gram-negative rods that grow on agar containing blood. The blood … Read moreLevinthal’s Medium
