摘要：Photosynthetic bacteria (PSB) wastewater treatment is a novel method with great potential for resource recovery. Light-dark cycle is important for photosynthetic microorganisms, but its impact on PSB wastewater treatment is still unclear. This study evaluated the effects of four light-dark cycles on PSB biomass, valuable substances production, and pollutant removal. Results indicate that the highest biomass concentration was obtained under 24?h light/24?h dark cycle. The highest concentrations o ...More
Photosynthetic bacteria (PSB) wastewater treatment is a novel method with great potential for resource recovery. Light-dark cycle is important for photosynthetic microorganisms, but its impact on PSB wastewater treatment is still unclear. This study evaluated the effects of four light-dark cycles on PSB biomass, valuable substances production, and pollutant removal. Results indicate that the highest biomass concentration was obtained under 24?h light/24?h dark cycle. The highest concentrations of protein and coenzyme Q10 were obtained under 3?h light/3h dark cycle (826.73 and 88.8?mg/g, respectively). Pigment production were stable under all light-dark cycles tested. Light-dark cycles had little effect on COD and TP removal, while 24?h light/24?h dark cycle resulted in the highest NH3-N removal. ATP and RuBisCO concentrations followed similar trends under different light-dark cycles. These results revealed that PSB could provide more biomass and valuable substances with given energy by changing light-dark cycles.Copyright ? 2018 Elsevier Ltd. All rights reserved. ...Hide
