Microbial degradation, compared with many other degradation processes, is the most important
pathway for the depletion of triazine herbicides in soil. The aim of this study was to determine the
growth potential of Pseudomonas sp. CY in the presence of atrazine and additional carbon (sodium
citrate) and nitrogen (ammonium-nitrate) sources. The experiment was performed with five
treatments: i) 100 mg/L atrazine (control); ii) One hundred mg/L atrazine + sodium citrate (0.3 %,
w/v); iii) One hundred mg/L atrazine + sodium citrate (0.3 %, w/v) + ammonium nitrate (0.6 %, w/v);
iv) Atrazine (300 mg/L) + sodium citrate (0.3 %, w/v) and v) Atrazine (500 mg/L) + sodium citrate
(0.3 %, w/v). The bacterial count was determined after incubation (7 days at 30°C) using the agar
plate method, while atrazine degradation was determined by measuring the optical density at 221 nm.
Pseudomonas sp. CY can partially utilize atrazine as the sole source of carbon and energy. The
highest values of th...e bacterial count were determined at the highest initial atrazine concentrations;
however, bacterial growth was not detected in these treatments. A significant impact of citrate on
bacterial growth and atrazine degradation was observed, while the addition of nitrate decreased the
atrazine degradation rate. This study confirmed that Pseudomonas sp. CY can be used as a prominent
candidate for the remediation of atrazine-affected environments.
