Note:

1.1.1. -- In DROPPS I & II, we developed a suite of experimental platforms and techniques that allow us to conduct in-situ observations of microbial kinetics near oil-water interfaces and their complex interactions, as well as to quantify simultaneously the changes by these microbial activities to the interface. In DROPPS III, we seek to first extend our efforts in understanding microscopic mechanisms of biodegradation, and expand our research to provide a holistic and complete assessment on the importance of these micro-scale processes on meso-scales roles to determine the fate of oil droplet. We will apply newly developed microfluidics that enables exquisite control of microenvironments and the state-of-the-art measurement techniques to complete the following tasks that are centered on understanding the impacts of these microbe oil interactions on the fate of oil. We will focus on establishing a holistic and comprehensive assessment on the role of micro-scale processes on the fate of oil droplet and to validate/substantiate our current hypothesis: bioconsumption of dispersed oil constitutes relatively small portion of oil droplets during the oil spill, while the major portion forms sediments (or marine snow) of which the formation processes are initiated and greatly enhanced by microbes via bio-aggregates formation around individual droplet and interactions among them.
