Chapman's Nutrient Medium

Chapman's culture medium

**Chapman's nutrient medium** is a medium for growing mycobacterium tuberculosis. The medium is named after its inventor John Hutchinson Jones, an American engineer and bacteriologist also known as Jones Henderson.

The nutrient medium is used for cultivating active forms of tuberculosis bacillus. Incubation of the rod suspension is carried out at a temperature of +32 to +35 degrees Celsius. After 2–3 weeks, yellowish mucus forms on the surface of the medium. The number of divisions of microorganisms is determined by the shape of the mucus bubbles, and the viability of the rod is determined by the thickness of the film. Microscopy of the medium or its seeding onto plates is used. Who invented the medium The inventor of this medium is the American engineer and bacteriologist John Henderson Jones Jones. He was born on February 14, 1853 in Birmingham (England), and graduated from the Faculty of Mathematics at Cambridge University in 1875.
