Özet

Pseudomonas aeruginosa and Ochrobactrum sp. were tested according to EPS production at different pH, temperatures, Remazol Blue concentrations, and incubation periods. Optimum pH was 7 for P aeruginosa and 8 for Ochrobactrum sp. according to the highest EPS amount. P aeruginosa produced the highest EPS (456.4 mg.l(-1)) after incubation for 48 h (40 degrees C) and Ochrobactrum sp. gave the highest yield (404.6 mg.l(-1)) after incubation for 72 h (30 degrees C). P aeruginosa had a low capacity to remove Remazol Blue (12.5%), however, Ochrobactrum sp. had a significant potential to remove Remazol Blue yielded as 89.4%.
