Thermo Scientific™ Motility B Medium

Description

• Demonstrate motility in nonfermentative, gram negative bacilli with Thermo Scientific™ Remel™ Motility B Medium
• Motility B Medium was formulated by Gilardi with a reduced agar concentration to facilitate the appearance of motility by non-fermentative, gram-negative bacilli such as pseudomonads 1,2
• The Gard plate technique that contains Motility B Medium poured into a petri dish 3 is used to select a motile strain from a population of cells which otherwise appears nonmotile
• Motility B Medium is a semisolid media that is used to demonstrate motility, primarily in nonfermentative, gram negative bacilli
• Agar provides a semisolid medium which makes motility interpretations macroscopic
• Ready- to-use: Convenience of prepared media
• Easy to interpret: Positive test- Diffuse growth extending away from the stab line; cloudiness or turbidity may be observed throughout the medium
• Negative test- Growth confined to the stab line
• Motility B Medium contains casein peptone and yeast extract that supply amino acids, peptides and vitamins to promote growth of nonfermentative gram-negative bacilli
• Sodium chloride provides essential electrolytes and maintains osmotic equilibrium
