Quantification of chemotaxis to naphthalene by Pseudomonas putida G7

Article Abstract:

The chemotactic response of Pseudomonas putida G7 to naphthalane was quantified using the capillary assay. Results from the capillary assay experiment indicated that the concentration of cells at the capillary mouth remained constant and was equal to the initial concentration in the chamber. The predicted bacterial concentration at the mouth ranged between two and three times the initial concentration throughout the chamber over a 1-h simulation.

Bacterial chemotaxis to naphthalene desorbing from a nonaqueous liquid

Article Abstract:

Research indicates that naphthalene desorption and degradation is associated with chemotaxis in Pseudomonas putida G7 and the effect of chemotaxis depends on the initial bacterial and naphthalene concentrations, suggesting the influence of the concentration gradients on the rates of mass transfer and biodegradation.

Continuous-flow capillary assay for measuring bacterial chemotaxis

Article Abstract:

Bacterial chemotaxis is said to have a significant impact on the structure and function of bacterial communities. According to the experiments performed, the results demonstrate that the continuous flow apparatus accurately measures diffusive transport.
