Pollution with heavy metals, especially those combined with petroleum, is one of the major environmental problems. These pollutants contaminate soil, water, and related ecosystems and cause problems for the flora and even humans. Considering the potential of microalgae for elimination of petroleum pollution and reduction of various heavy metals contaminations, this study was carried out using Calothrix sp., isolated from polluted areas with the aim of investigating the reduction of nickel as well as studying some physiological behaviors of microalgae. Experiments were designed using the Design Expert software and factors such as PH (pH4-9), nickel concentration (5-100 mg/L), and time (30-120 min) were considered. Results showed that at pH 8, 80.74 mg/L nickel concentration, and 48.24 min the highest nickel uptake (69%) was observed. Treatment of algal biomass with different chemical and physical factors in various forms, such as immobilization or use of its metabolites could improve and facilitate the absorption process and paves the way for the potential application of these microalgae in subsequent purification systems.
