Optimal light intensity for the growth of Rhodopseudomonas palustris strain B1 for application in sago and palm oil mill effluents treatment
The light intensity for the growth of the phototrophic R. plaustris strain B1 in glutamate-malate medium has been optimized at 4 klux. This condition was used for the treatment of sago effluent and POME using R. palustris strain B1, with three days retention time. At 10% (v/v) inoculum size, there w...

| Summary: | The light intensity for the growth of the phototrophic R. plaustris strain B1 in glutamate-malate medium has been optimized at 4 klux. This condition was used for the treatment of sago effluent and POME using R. palustris strain B1, with three days retention time. At 10% (v/v) inoculum size, there was a 67% reduction for both COD and BOD of the sago effluent. By comparison the reductions in POME were only about 35% in undiluted effluent and 45% in 50% (v/v in tap water) diluted effluent. |
