The lower reduction in percentage of coliforms found in this study was possibly caused by the different culture medium and initial cell concentrations used. The use of diluted medium stimulated competition for carbon sources where coliform bacteria and P. aeruginosa were forced to overlap. Technically, coliform bacteria would have advantages due to shorter doubling-time when compared to P. aeruginosa (Tamagnani and Gonzáles, 1997; Camper et al., 1991). Nevertheless, pyocyanin-producing P. aeruginosa strains have proven to be more nutritionally versatile and capable of adaptation when competing with another microorganism. Moreover, literature reported that under competition for nutrients, coliform bacteria usually delay in lag time Vaconcelos et al. 1137 24 48 72 96 Time (h) against PA2 against PA14 against PA16 Control Fig. 2.

Although coliform bacteria are the universal indicators of fecal pollution in waters for human consumption, detection of P. aeruginosa as a complementary test is matter of concern because presence of P. aeruginosa and low coliform bacteria concentration would hide a major risk and would compromise the results from current methods used for water analysis. P. aeruginosa creates an element of concern, as this species can cause nosocomial infections or multi-drug resistant strains which may be untreatable. The three most harmful strains in this study were also resistant to at least three important antibiotics used for the treatment of P. aeruginosa infections, as follows (concentration tested in µg.ml -1 ): ciprofloxacine (5), norfloxacine (10) and imipenem (10), and were sensitive to amikacin (30), ceftazidime (30), gentamicin (10), ticarciline/clavulanate
