The Role Of Bacteria-Particle Interactions In Marine Snow Dynamics, Emily M. Yam
The Role Of Bacteria-Particle Interactions In Marine Snow Dynamics, Emily M. Yam
Dissertations, Theses, and Masters Projects
Marine snow aggregates are one of the primary vehicles for deep-sea carbon sequestration. Bacterial activity on marine snow affects both degradation and aggregation processes that determine the flux of carbon to depth, biogeochemical cycling, and microbial food webs. The microscale processes occurring on aggregates depend on specific interactions between bacteria and particles. In this thesis, I describe two such interactions which have larger scale implications on marine snow dynamics: (1) the effects of starvation on bacterial motility and colonization behaviors on marine aggregates and (2) interactions between bacteria and phytoplankton which could contribute to the production of TEP.
