ABSTRACT
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 (40ºC) and Ochrobactrum sp. gave the highest yield (404.6 mg·l-1) after
incubation for 72 h (30ºC). 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%.
