test determines if there is acetoin found in a bacterial culture. Using alpha-naphthol and potassium hydroxide detects if there is acetoin in the culture. The test is determined by the digestion of glucose to acetylmethylcarbinol. The test will react with alpha-naphthol and potassium hydroxide if glucose is being broken down and turn a red color. If a test is positive it will show a maroon colored band on the top portion of the broth. Lab Results E. coli is MR+ because it does ferment

They come in all sorts of shapes including rods‚ spirals‚ and spheres. Some bacteria
