Methyl red is a pH indicator dye that is commonly used in microbiology to differentiate bacteria based on their fermentation patterns. It is a synthetic dye with a deep red color that changes to yellow in acidic conditions.
Chemical Properties
Methyl red is an azo dye, meaning it contains an azo group (N=N). It is water-soluble and has a molecular formula of C15H15N3O2. The dye molecule absorbs light in the blue range and reflects red light, giving it its characteristic red color.
Microbiological Applications
In microbiology, methyl red is used in the Methyl Red (MR) test to identify bacteria that produce stable acids from glucose fermentation. The test distinguishes between bacteria that produce a mixed acid fermentation pathway, resulting in a pH below 4.4 and turning the methyl red indicator red, and those that produce other fermentation byproducts.
Industrial Uses
Aside from its applications in microbiology, methyl red is also used in various industrial processes. It is a common pH indicator in chemistry labs and is used in the production of dyes, pigments, and other chemicals. Its vibrant red color and pH sensitivity make it a versatile compound in different industries.
Overall, methyl red plays a crucial role in microbiology for differentiating bacterial species based on their metabolic pathways. Its distinct color change properties and chemical stability make it a valuable tool in various scientific and industrial applications.
