Abstract

Adenine nucleotide pools and adenylate energy charge distributions were determined by using a laboratory-generated quasi-steady-state Pseudomonas aeruginosa biofilm. The method used involved freezing and sectioning of the intact biofilm, followed by extraction and assay of the adenylates in the sectioned material. Results indicated an increase in adenylate energy charge of about 0.2 units from the bottom to the surface of the biofilm. However, energy charge values were generally low throughout the biofilm, reaching a maximum of only 0.6 units. Of the adenylates measured, AMP was the predominant nucleotide, especially in the deeper parts of the biofilm profile.
