Methyl red test. SAE, WT, and SAEC were grown with or without 0.125%, 0.25%, 0.5%, and 1% (g/mL) glucose for 24 h. Five drops of methyl red were added to the culture supernatant and then gently rolled to disperse the methyl red. The supernatant will turn yellow at neutral pH but turn red at pH < 4.0.
