Which of the following is added to decarboxylase media that turns purple when conditions are alkaline/basic and yellow when conditions are acidic? Lysine, Glucose, ornithine, Broom Cresol Purple, Phenol red An acidic environment is inhibitory to decarboxylase activity. true or false? Lysine decarboxylase media is yellow after incubating an organism in it at 37 degrees for 24 hours. Which of the following can be interpreted from this result?
