Season’s Greetings – E. Coli Plate

Anne Wilkinson from the Stopford Labs, has created a snowflake using Escherichia Coli (E. coli 165) grown on an Eosin Methylene Blue agar. The shiny blue/green colour of the snowflake is produced when the E. coli, which is a lactose fermentor, produces acids that precipitate out the methylene blue in the agar medium.
