MOTILITY TEST MEDIUM 500 grams/bottle

Motility Test Medium is a semisolid medium used for the detection of bacterial motility. The use of semi-solid media for the determination of bacterial motility eliminates the shortcomings of microscopic methodes like the hanging-drop technique. Tryptose is the source of nitrogen, carbon, nutrients and amino acids essential for growth. Sodium chloride maintains the osmotic equilibrium of the medium. Small amount of agar helps to create a semisolid medium. Inoculate by the stab method with a straight needle. The motility is manifested macroscopically by a diffuse zone of growth spreading from the line of inoculation. Non-motile bacteria generally give growths that are confined to the stab-line, have sharply defined margins.
