“…Daneshvar et al [43] studied the nitrate removal efficiency for Chlorella vulgaris against several macro and micronutrients concentrations, nitrate concentration, inoculum sizes, initial pH of the medium, and different concentrations of sea salt and sodium chloride, and concluded that nitrate removal efficiency can be improved by manipulating other cultivation conditions besides nitrogen concentration. Moreover, Fan et al [44] reported that nitrogen uptake rates vary among microalgal species mostly due to their different metabolic processes that limits not only their biochemical composition but also their nutrient acquisition and assimilation abilities. In the previous study, the nitrogen to phosphorus ratio had a substantial effect on nutrients removal by microalga.…”

“…Scenedesmus obliquus had higher biomass concentration with 356 mg L -1 than that of Spirulina platensis at 8000 lux. In addition, Scenedesmus obliquus had higher lipid percentage with 36.8% mg L -1 [7]. Aketo et al investigated lipid contents of P. kessleri NKG021201 and C. saccharophilum NKH13 in municipal wastewater.…”

“…It can be used for animal feed, biofuel, food, fertilizer and by-product production. Biomass production depends on environmental factors such as light, pH, the availability of macro and micro components and various types of wastewater [7]. The biomass can be obtained in the various media and microalgae can be cultivated in different wastewaters such as domestic, municipal, swine and industrial wastewater and they can remove some toxic compounds from wastewater [8,9].…”

Microalgae can generally maintain the high amounts of biomass in the wastewater and they can be converted from biomass to bio-butanol. Bio-butanol is a liquid biofuel and it has significant physical and chemical properties. In this study, we carried out bio-butanol production from Borodinellopsis texensis CCALA 892 grown in various concentrations of the municipal wastewater. Also, we determined biochemical composition ratios of microalgae samples and studied the some antioxidant enzymes such as catalase, superoxide dismutase and ascorbate peroxidase. In the current study, bio-butanol was produced by the acetonebutanol-ethanol (ABE) fermentation method. The microalgae sample grown in 25% of wastewater had the highest biomass productivity among five wastewater samples with 0.114 ± 0.002 g L-1 d-1. The carbohydrate and protein concentrations of control group increased day by day and their values reached stationary phases at seven days. The sample grown in 25% of wastewater had the highest carbohydrate concentration with 0.30 g L-1 and protein concentration with 0.35 g L-1 at the stationary phase. The maximum enzyme activities for catalase, superoxide dismutase and ascorbate peroxidase were 15.33 ± 0.88, 8.67 ± 0.67 and 33 ± 1.53 µmole/mg, respectively at 25% of wastewater. In addition, bio-butanol content of B. texensis CCALA 892 was 3.63 ± 0.21 g L-1 and its bio-butanol yield was found as 0.18 ± 0.011 g/g sugar. In the next study, we can examine large scale butanol production.

“…The microalgae biomass of P. kessleri grows rapidly, reaching 376.667mg L −1 in three days [51]. The biomass concentration of the remaining three microalgae exceeded 200 mg L −1 on the third day [52][53][54]. However, the biomass concentrations of the four microalgae T. obliquus, P. kessleri, Hydrodictyon sp., and S. quadricauda were lower compared with previous studies.…”

Microalgae have shown great potential in wastewater treatment. This study evaluates the growth and nutrient removal characteristics of five different microalgae strains, namely Chlorella vulgaris, Tetradesmus obliquus, Parachlorella kessleri, Hydrodictyon sp., and Scenedesmus quadricauda, in simulated domestic wastewater. The five microalgae could adapt to wastewater, but the growth potential and nitrogen removal capacity were species dependent. The nutrient removal effect of the microalgae used in this experiment was about 50% in the first two days. Parachlorella kessleri, selected from the five strains of green algae, shows good potential in removing nutrients from simulated domestic wastewater. For the simulated domestic sewage treated with Parachlorella kessleri, the chemical oxygen demand was almost completely reduced, and ammonium-N (NH4-N) and total nitrogen (TN) removal exceeded 70% at the end of the 10-day treatment. Total phosphorus (TP) removal was slightly worse, more than 65%. Parachlorella kessleri showed the best growth in sewage with the highest biomass reaching 366.67 mg L−1 and the highest specific growth rate reaching 0.538 d−1. This study can provide a reference for selecting suitable microalgae species to treat actual domestic sewage.
