Measurement of the kinetics of bacterial adherence to hexadecane in polystyrene cuvettes

Abstract The kinetics of bacterial adherence to hexadecane were measured using disposable polystyrene cuvettes. The rate of adherence was exponential, and was itself linearly dependent on the water:hexadecane ratio employed. The dependency of the rate of adherence on the water:hexadecane ratio, termed the removal coefficient, varied from 4.7 min⁻¹ for Streptococcus pyogenes to 72 min⁻¹ for Acinetobacter calcoaceticus . The removal coefficient of Serratia marcescens was a function of growth temperature, 48 min⁻¹ following growth at 30°C as opposed to 5.8 min⁻¹ for 35°C-grown cells.
