“…This is contrary to what it is expected whereby the DO of the culturing systems increases as the pH increases, due to formation of oxygen molecules, a byproduct of photosynthesis. Microalgae uptake of nutrients from the growth medium is largely dependent on the respective compositions in the medium [24]. The presence of nitrogen and phosphorus is essentially emphasized due to their support for microalgae growth.…”

Application of wastewater for algal biomass production can not only lead to production of thousands of tons of biomass for subsequent biofuel production, but also can provide for significant removal of contaminants in wastewater. The aim of the present study is to evaluate the growth, contaminant removal, and biochemical component (lipid, carbohydrate, and protein) accumulation potential of Chlorella vulgaris, Scenedesmus obliquus, and Oocystis minuta cells in wastewater supplemented with different concentrations of sulfate, nitrate, and phosphate. The results show maximum biomass productivity of 33, 19, and 98 mg dw/L/d for C. vulgaris, S. obliquus, and O. minuta, respectively. Phosphate removal (more than 90%) was highest in the culture with O. minuta; about 93% nitrate was removed by C. vulgaris, and the highest sulfate removal of 36% was observed in the culture with S. obliquus. The biochemical composition of the microalgae cells is in the ranges of 22-65% carbohydrate, 19-38% protein, and 8-17% lipid. This indicates that carbohydrate and protein are preferentially accumulated as compared to lipids under the growth conditions investigated for each of the microalgae strains.Keywords Remediation · Lipids · Microalgae · Carbohydrate · Photosynthetic organism Abbreviations ODOptical density AFDW Ash-free dry weight R 2 Coefficient of determination P Biomass productivity t 1 , t 2 Culture duration, time t 1 and t 2 C 1 , C 2 Biomass concentrations at time, t 1 and t 2 A Mass of lipid in the extract BMass of dried microalgae biomass BSA Bovine serum albumin * Sheriff Olalekan AjalaPublisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Increased interest in renewable, carbon-neutral energy sources makes processing biodiesel from microalgae has become the objective for many researchers and companies. Some kind of wastewater including municipal, industrial and agricultural wastewaters have been identified as alternate growth mediums. Produced water is the largest byproduct of the oil and natural gas extraction process which constitutes of high concentration of pollutants, such as dissolved nitrogen, phosphorus, dissolved organic carbon, heavy metal and monocyclic aromatic compound like BTEX. The purpose of this study is to identify Chlorella sp. potential for producing lipid in artificial produced water. Variations made in this study consist of 0%, 25%, 50%, 75% and 100% volume of artificial produced water to the control Walne medium. The highest specific growth rate and biomass productivity of Chlorella sp. achieved by culture grown in 25% wastewater with a value of 0.225 day−1 and 0.175 g L−1day−1, respectively. The highest lipid yield and productivity in mixed culture of artificial produced water and Walne medium achieved by culture in 25% artificial produced water with value of 0.231 and 40.48 mg.L−1.day−1. C16 and C18 fatty acids which dominated the lipids of Chlorella sp. in all culture variations indicated that the lipid of Chlorella sp. were suitable for producing high quality biodiesel.

“…In this system, it was found that 460 mg/ (L·d) biomass could be harvested with a lipid content of 27%, together with more than 86% nutrient removal. A higher lipid content of 32.7% was also observed in microalgae biomass cultivated with municipal wastewater (Lam et al, 2017). Moreover, other high-value products, such as pigments, fertilizers, nutraceuticals (e.g.…”
