Assays were performed in 500 mL Erlenmeyers containing
300 mL of liquid media. Cells of Enterobacter sp., Pseudomonas
sp. and Morganella sp., collected from agar plates (BMM,
agar and Acid Orange 7) were inoculated separately and combined
into the media. The cultures were incubated at 30 C under
magnetic stirring at 150 rpm. Control was performed
without bacteria inoculum.
