Bordet-Gengou culture medium, also known as Bordet medium or nutrient broth, is one of the most important tools in the medical and scientific field, often used for cultivating living microorganisms. It was invented in the 30s of the 20th century by French scientists Pierre Jean Bordet and Alexandre Thyssen-Zhang.
A nutrient medium is a liquid mixture containing the basic components necessary for the growth and development of microorganisms, such as nutrients, dyes, disintegrants and antibiotics.
