Isolation of a Thermotolerant Photosynthetic Bacterium, Rhodobacter sphaeroides Strain, NAT, and Its Capacity for Oil and Chemical Oxygen Demand Removal at High Temperatures

Isolation of a Thermotolerant Photosynthetic Bacterium, Rhodobacter sphaeroides Strain, NAT, and Its Capacity for Oil and Chemical Oxygen Demand Removal at High Temperatures

A thermotolerant photosynthetic bacterium NAT identified as Rhodobacter sphaeroides was isolated. When alginate-immobilized cells of strain NAT were used in high-temperature treatment of artificial sewage wastewater containing oil, the chemical oxygen demand (COD) decreased by 80% and 76% of the oil...

Zusammenfassung:A thermotolerant photosynthetic bacterium NAT identified as Rhodobacter sphaeroides was isolated. When alginate-immobilized cells of strain NAT were used in high-temperature treatment of artificial sewage wastewater containing oil, the chemical oxygen demand (COD) decreased by 80% and 76% of the oil was removed after 96 h of treatment at 55 °C. Lipase activity was observed in the culture.
