A large oil spill in the Pacific Ocean is
threatening marine life. Scientists charged
with cleaning up the spill believe
bioremediation is the best option, but they
are not sure what type of bacterial species to
use in the bioremediation process. To help
them in their decision, they have listed the
nutritional modes of each species. Given
your knowledge of the different nutritional
modes of bacteria, which nutritional mode
would be most beneficial in bioremediation
of the oil spill?

Extremotroph
Photoautotroph
