HRP system applications:
Glucose/insulin regulation system
Problem: no receptor in E. coli to detect glucose directly
AHL produced in biofilms:
(Notes on the journal modeling AHL production in biofilms of the same bacterial population)
AHL synthesis is subject to autoinduction in which production of AHLs operates
as a positive feedback loop.
Assumptions made in the model:
All bacterial cells are physiologically identical with regard to size, shape and permeability of the cell membrane, as well as production and degradation rates of the signalling molecules
Bacterial population exhibit a standard logistic growth pattern
No metabolic or physiological lag is assumed
At very low Cbc, the net rate of AHL production, h(Cbc), is assumed to be determined solely by the difference between basal production, Bp, and degradation of AHLs
Degradation of AHLs is proportional to the concentration of AHL and occurs at a rate d*Cbc
Not considered in the model: permeability constant a, which is characteristic of the bacterial cell membrane, the diffusability of a given AHL, and the viscosity of the cell and the biofilm
Conclusions from the model: high concentrations of AHL inside cells could be achieved at very low population densities. Rapid rise in AHL concentration early in population growth, followed by a plateau, followed by another rise to a second plateau
