  1. 2. A Lactobacillus associated with dental caries
  2. 4. Some oral bacteria can reduce this dietary molecule from vegetables which eventually becomes an important signalling molecule
  3. 10. A small chemical signaling molecule used for communication between microorganisms
  4. 13. An early coloniser of plaque, can use lactate as an energy source
