Why is methyl red indicator more suitable?

Methyl red is used as a pH indicator or for the identification of some bacteria.


In methyl red testing what does E.coli do?

E. coli produces acidic byproducts during fermentation, causing the methyl red indicator to turn red in a positive test result. This indicates that E. coli can metabolize glucose with mixed-acid fermentation.


When do you use methyl red instead of phenol red?

Methyl red is typically used in pH tests to determine if a solution is acidic (pH<4.4), while phenol red is typically used to approximate the pH of a solution (between pH 6.8-8.4). Use methyl red when you need to indicate a more acidic pH level, and phenol red for a broader pH range closer to neutral.


Is staphylococcus aureus methyl red positive?

Staphylococcus aureus is typically methyl red negative. Methyl red test is used to determine the ability of an organism to perform mixed-acid fermentation of glucose, with a positive result indicating a significant drop in pH. Staphylococcus aureus is not known to produce enough acid to yield a positive result with the methyl red test.


What is the similarities between both methyl orange and screen methyl orange?

Methyl orange and screened methyl orange are both synthetic dyes commonly used as indicators in titrations. They both change color at specific pH ranges: methyl orange transitions from red to yellow in acidic solutions, while screened methyl orange transitions from yellow to red in basic solutions. Both dyes are water-soluble and widely available for laboratory use.
