Dataset for: Adhesion of Marinobacter hydrocarbonoclasticus to Surfactant-Decorated Dodecane Droplets

This project investigated the effect of surfactant chemistry and concentration on the initial adhesion of Marinobacter hydrocarbonoclasticus at the interface of dodecane droplets suspended in water, investigating both the time-dependent adhesion of bacteria at the dodecane/water interface and the dependence of adhesion on droplet size and surfactant concentration. The dataset contains z-stack images (.tiff) for three different drop sizes at different time intervals, and z-stack images (.tiff) for two different drop sizes at different surfactant concentrations. The data analyzed consists of: (a) normalized drop diameter as a function of inner to outer fluid flow rates in microfluidic device; (b) number of cells as a function of time; (c) time constant of adhesion as a function of drop diameter; (d) orientation distribution of cells at dodecane/water interface for three drop sizes; (e) cell areal density as a function of surfactant concentration; (f) interfacial tension as a function of surfactant concentration; (g) cell areal density as a function of interfacial tension; and (h) zeta potential of emulsion droplets. This dataset is associated with GRIIDC dataset R5.x285.000:0008 which includes images (.bmp) for dodecane-in-water emulsions prepared using co-flow microfluidic device and pendant drop movies (.avi files) at different surfactant concentrations for the dodecane/water system.
