Some food in this world are made using microorganism to produce a desire flavour‚ taste and texture of the food. For examples: yogurt‚ tapai‚ cheese‚ bread and others. Starter cultures is used in these food production. A starter culture is a microbiological culture which actually perform fermentation. These starters usually consist of a cultivation medium‚ such as grains‚ seeds‚ or nutrient liquids that have been well colonized by the microorganisms used for the fermentation. These starters are formed

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 glucose and the has a high acidity produced during the fermentation. E Coli is VP- because it does not make acetyl methyl carbinol‚ a neutral product. E. Coli produces more acidic products S. epidermidis
