Sodium dodecyl sulfate, (SDS) is an anionic surfactant that widely utilized in industry and households. Which represent toxic effects to the health and aquatic organisms. The bacterial strains Pseudomonas aeruginosa and Pseudomonas otitidis were isolated from the water samples from waste disposal sites (Taif Governate, Kingdom of Saudi Arabia). So, in the present study, we have made an attempt to improve the biodegradation of SDS by Pseudomonas aeruginosa and Pseudomonas otitidis by different methods such as mutation (Physically and chemically), physically by exposure of bacterial strains to ultraviolet radiation (UV) and chemically by using chemicals such as ethidium bromide (EtBr), also biodegradation rate of SDS can be increased by immobilization technique. The bacterial strains were immobilized in alginate beads, and its SDS degradation efficiency was observed to increase many fold than free strains.
