Fueled by the chemicals dissolved in the vent fluids, these areas are often home to large and diverse communities of thermophilic, halophilic and other extremophilic prokaryotic microorganisms (such as those of the sulfide-oxidizing Beggiatoa genus), often arranged in large bacterial mats near cold seeps.

Biofilm |
The transcriptional regulator CsgD is central to Biofilm formation, controlling the expression of the curli structural and export proteins, and the Diguanylate cyclase, adrA, which indirectly activates cellulose production.
Biofilm from the mixture of sugar and plaque create a suitable environment for S. sobrinus to grow.
