Research Topic: Biodegradation of Polycyclic Aromatic Hydrocarbons (PAH) in Arctic Sea Ice Brine Channels: Protistan Grazing on PAH Degrading Bacteria

Advisor: Nancy Kinner

Heather Ballestero
Description of Research


This study focuses on long term biodegradation studies of varying crude oil concentrations in different cold temperatures and high salinity regimes to mimic what would happen if oil were spilled in the Arctic oceans and froze into the Sea Ice, concentrating the oil in ice brine channels.  The microbial populations are monitored to see the relationship between the polycyclic aromatic hydrocarbon (PAH) concentrations, bacterial counts, and the protest counts (prey on bacteria).  The water soluble fractions of oil (PAH) are analyzed over time with a gas chromatograph- flame ionization detector (GC-FID) and the microbes are counted using epifluorescent microscopy techniques.
