I investigate how pathogenic bacteria such as Vibrio in symbiosis with certain algal species can help provide the environment with more oxygen.

One in every five breaths that you take, come from photosynthetic phytoplankton that live beneath the ocean surface. However, some of these phytoplankton cannot protect themselves from destructive hydrogen peroxide in the environment. That’s exactly where commensal bacteria come in to the picture: the bacteria Vibrio fisherii can act as helpers for the phytoplankton by excreting the enzyme catalase. Catalase, an enzyme, breaks down hydrogen peroxide into oxygen so that the phytoplankton are protected and able to perform photosynthesis efficiently. Indeed, a breath of fresh air!
