Raoultella planticola
Raoultella planticola was a bacterium.
In 2017, Agrofuel Research Operations genetically modified an sample of the bacteria using the enzyme EC 31. Due to a misplaced decimal point, the bacteria became world-ending.
The bacteria produced ethanol, which filled the greenhouse, as well as the lab. When the lab's vent systems cycled, it would be released into the Earth's atmosphere and destroy the world within a year as predicted by the Monks. The Twelfth Doctor destroyed the bacteria and saved the Earth by blowing up half of the lab the bacteria was created in, the fire burning the bacteria away. (TV: The Pyramid at the End of the World)
