The higher incubation temperature of 44 °C supports the growth of E. coli and at the same time inhibits the development of secondary bacteria. Sub-lethally damaged bacteria can also be detected through pre-incubation (6 hours at 25 °C). E. coli and coliform bacteria form yellow colonies. Secondary gram-positive bacteria are inhibited by bile salts and lauryl sulfate.
