Bioremediation of pharmaceutical industrial effluent by organisms screened from effluent discharged soil
Two bacterial strains were isolated from pharmaceutical effluents discharged soil. The samples were identified as Klebsiella pneumonia and Pseudomonas aeruginosa the biological degradation was carried on two bacterial isolates separately added to pharmaceutical effluent water. After proper interval were analysed the physic chemical parameters such as pH, Turbidity, Chemical oxygen demand (COD), Biochemical oxygen demand (BOD), Total solids (mg/L), Total dissolved solid (TDS), Chlorides (mg/L), Alkalinity, Hardness (mg/L) and Aromatic organic compound of phenol (Folin- Ciocalteu method). The maximum degradation was observed at 48 hours in Pseudomonas aeruginosa (72%) and Klebsiella pneumoniae maximum degradation was observed at 48 hours (70%). On comparative study of the biodegradation ability of Bacillus subtilis and Alcaligenes eutrophus maximum biodegradation ability was observed in Bacillus subtilis. Finally, it was concluded that Pseudomonas aeruginosa can able to highly degrade phenolic content in the pharmaceutical effluent. It can be improved and used industrially for the large scale treatment of pharmaceutical waste effluent water and improvement of its quality for its reuse. Pseudomonas aeruginosa can be recommended for controlling the pollution caused by pharmaceutical effluent.
