  1. Subseafloor Bacterial Invasion By: Antoine A. Akl

  2. Outline • What is Subseafloor bacteria? • How is it becoming a problem? • What causes it to be Invasive? • What can we do to prevent it?

  3. Subseafloor bacteria • Bacteria found under the sea floor within the sediment. • Contain 1/3 of the world’s microbile biomass (bacteria)

  4. Rapid Evolution! Bacteria is evolving at an alarming rate. Capable of surviving outside the subsea level due to over-activated DNA-repair sequences and Antibiotic target genes. Mean? They can withstand harsher environments' by repairing itself and resist natural antibiotics let alone use antibiotics as a source to obtain nutrients. Now spreading throughout the sea causing infection and diseases among marine life (plants&animals) and environmental modifications.

  5. How is it becoming Invasive? • Stirring up the sediment! • Environmental construction/reconstruction • Drilling • Any other form of unnatural cause • Promoting the Behavior! • Chemical waste!!!

  6. Prevention? -Stop unnecessary environment reconstruction. -Dispose of medications/chemicals appropriately.
