For the selected isolates, PGA production was determined for various concentrations of glucose and phenylacetic acid in the medium. PGA production by E. coli isolates was completely repressed by glucose concentration above 5 g/l. Production of PGA by E. coli isolates was completely dependent upon the presence of PAA in the medium and optimal enzyme activity was obtained between 1 g/l and 2 g/l of PAA. Enzyme activity was found to be highest when PAA was used as an inducer. PGA production by our local E. coli isolates was completely inducible.
