Application

Xylose Disks are used to differentiate bacteria on the basis of carbohydrate fermentation abilities.

Principle

Xylose disks are used based on the principle that microorganisms can only ferment certain carbohydrates. The ability to cleave various carbohydrates depends on the type of enzymes they possess. This can be detected either by gas production (CO2) in liquid media or change in color of the pH indicator because of the acid production.

Differentiation of Escherichia coli from coliforms

There are many other methods of detection to indicate the presence of E. coli. Review common tests and biochemical reactions for this contaminant.

Differentiation and Identification Media for Salmonella

Salmonella contamination is the second leading cause of food-borne illness worldwide. Controlling outbreaks of Salmonella is an important task for food regulators, restaurants and the food industry in general. The Salmonella family includes over 2,300 serotypes of bacteria, but two types, Salmonella enteritidis and Salmonella typhimurium, are responsible for about half of all human infections. Most outbreaks of Salmonella are traced back to dairy, poultry and meat products, but Salmonella can grow on nearly any food. Chicken, eggs and their derivative products are particularly high risk.

Listeria: a Survivor

In recent years it has been recognized that Listeria is an important public health problem. The disease affects primarily people of advanced age, pregnant women, newborns, and adults with weakened immune systems.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
