INTERACTION BETWEEN ESCHERICHIA COLI AND PSEUDOMONAS AERUGINOSA IN MIXED CULTURES

Abstract

Both continuous and stationary cultures were used to detect interactions between Escherichia coli and Pseudomonas aeruginosa in mixed cultures, with pure cultures included as controls. The interactions observed were both pH and substrate dependent. Stimulation of P. aeruginosa in mixture was the most marked interaction, and was, in part, due to changes in carbohydrate metabolism.
