Abstract
Various wastewater and substrates are used as media to preserve existing water reserves for algae cultivation and to eliminate or reduce the cost of chemicals used. In this study, the growth, biochemical content, nutrient removal capacity, and antioxidant activity of Chloroidium ellipsoideum isolated from Lake Sapanca was investigated, using the wastewater as a culture medium taken from the Karaman Wastewater Treatment Facility, located within the borders of Sakarya province. While Bg11 medium was used as a control in the study, the growth of C. ellipsoideum was followed for 7 days in wastewater as diluted and undiluted environments with Bg11 medium. Algae grown in the Bg11:Ww had the highest dry biomass amount, and total protein and total carbohydrate percentages. While the most effective removal of nitrate-nitrogen was observed in the Ww, the most effective removal of orthophosphate was observed in Bg11:Ww. The total phenolic content of C. ellipsoideum grown in three environments was determined as 29.2 mg GAE g−1 in Bg11, 18 mg GAE g−1 in Bg11:Ww and 22.4 mg GAE g−1 in Ww. Additionally, antioxidant activity was determined to be related to the amount of total phenolic substances. As a result, this study has demonstrated its usability in algae production by supporting the wastewater environment with standard nutrient media in attempts to improve the high costs of algae cultivation.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
