“…In addition, the DC from inland desalination plants (Volkmann et al 2007) and other wastewaters (Olguín et al 2001;Bertoldi et al 2006;Li et al 2011) could provide water and nutrients (nitrogen and phosphorus) for the production of microalgal biomass. For this reason, it was possible to reduce the levels of three nutrients present in the BBM control, from 0.25 to 0.09 g L −1 for sodium nitrate, 0.175 to 0.014 g L −1 for monobasic potassium phosphate, and 1.0 to 0.2 mL L −1 for micronutrient solution.…”

“…A microalgal culture can be used to efficiently remove nutrients from salty waters, transforming the nutrients into valuable biomass as feedstock (Volkmann et al 2007) and it is generally recognized that microalgae play an important role in the self-purification of wastewaters (Pittman et al 2011;Olguín 2012). Furthermore, the development of culture media based on wastewater has become an important area of study, resulting in a large number of culture media obtained from different types of mineral media, organic substrates, and synthetic or real wastewaters (Orpez et al 2009;Biller et al 2012;Dickinson et al 2013;Tuantet et al 2014).…”

“…For marine algae, salinity is expected to have some effect on the metabolism (Katz et al 2007), especially on important cell membrane constituents, such as lipids (Takagi and Karseno 2006) and fatty acids (Azachi et al 2002;An et al 2013). In a previous paper, Volkmann et al (2007) investigated the influence of DC combined with Paoletti medium on the fatty acids composition of Arthrospira platensis. In addition, DC could be used as a nutrient source to grow plants, such as giant saltbush (Atriplex nummularia) (Porto et al 2001), which has been used as animal feed and even for fish farming (Oreochromis sp.)…”

Desalination concentrate (DC) is a potential medium for microalgal cultivation since it contains an abundance of mineral salts. In this study, the feasibility of growing Chlorella vulgaris with DC was evaluated and the influence of DC concentration on the growth, biomass productivity, and biochemical composition was assessed. Media comprised of DC mixed with bold basal medium (BBM) in different concentrations were prepared for microalga cultivation. A sequential statistical methodology, comprising fractional factorial design and response surface methodology (RSM) was applied to enhance the biomass production. The growth of C. vulgaris was promoted with 75 % BBM+25 % DC compared with the BBM control. C. vulgaris biomass production (0.59 g L −1 ) was observed with 75 % BBM+25 % DC with optimal concentrations of sodium nitrate (0.09 g L −1 ), monobasic potassium phosphate (0.014 g L −1 ), and micronutrient solution (0.20 mL L −1 ). The gradual increase of DC had a strong effect on the biochemical composition of C. vulgaris. Carbohydrate fiber and protein contents were estimated to be 14.4 and 51.3 %, respectively, when the microalgae were cultivated in 75 % BBM +25 % DC. The lipid content (12.5 %) of C. vulgaris cells was highest at the optimized BBM DC concentrations. When grown in the BBM control and optimized BBM+DC media, C. vulgaris produced lipids rich in polyunsaturated fatty acids (C18:3 ω3) and monounsaturated fatty acids (C18:1). These results indicated that DC is a feasible alternative for the mass cultivation of C. vulgaris.

“…El incremento en el pH puede estar correlacionado al consumo de la fuente de carbón a partir del bicarbonato que contiene el medio de cultivo Zarrouk, los iones de bicarbonato son asimilados por la cianobacteria y subsecuentemente convertidos en dióxido de carbono y carbonato (Raoof et al, 2006). El pH alcalino pudo favorecer la solubilización de las partículas de CBR tipo lignito presentes en el medio, y también el contenido de SH en el mismo, aumentando así la disponibilidad de iones minerales para la nutrición de A. platensis (Volkmann et al, 2007).…”

ResumenLa producción de biomasa y pigmentos a partir de Arthrospira platensis ha cobrado gran importancia, debido a que estos tienen aplicaciones en producción de alimentos, metabolitos de interés biotecnológico e industrial. No obstante, para la producción de biomasa y pigmentos se han utilizado diversos sustratos que generan altos costos. Se estudió el crecimiento y producción de pigmentos de A. platensis bajo la influencia de seis concentraciones de carbón de bajo rango (CBR) tipo lignito (10, 20, 30, 40, 50, 60 mg/L) frente a una concentración de AIA (80 mg/L), se realizaron cultivos en batch en medio Zarrouk suplementados con CBR tipo lignito y AIA, bajo condiciones de aireación constante y fotoperiodos de 12:12 horas, durante 33 días. Los valores promedios más altos que se obtuvieron en cuanto a producción de biomasa y pigmentos se lograron en los cultivos suplementados con 50 y 60 mg/L de CBR tipo lignito con respecto a los controles. Los resultados obtenidos dan constancia al uso potencial del CBR como materia orgánica humificada, rica en nutrientes para el cultivo A. platensis que podrían ser aprovechado en medios acuíferos que son expuestos a la explotación carbonífera, contribuyendo a procesos de depuración y biorremediación de aguas contaminadas con materiales carboníferos.Palabras clave: carbón tipo lignito, pigmentos, solubilización, tasa de crecimiento. AbstractThe Biomass production and pigments from Arthrospira platensis has become very important, because these have applications in food production, metabolites of biotechnological and industrial products. However, for the production of biomass and pigments they have been used various substrates that generate high costs. Growth and pigment production A. platensis under the influence of six concentrations of low rank coal (LRC) type lignite (10, 20, 30, 40, 50, 60 mg / L) was tested against a concentration of AIA (80 mg / L), in batch cultures, performed in Zarrouk medium supplemented with LRC type lignite and AIA, under constant aeration and photoperiod of 12:12 hours, for 33 days. The highest average values obtained in terms of biomass production and pigments were achieved in the cultures supplemented with 50 and 60 mg/L of LRC type lignite with respect to the controls. The results provide evidence of the potential use of CBR as humified organic matter, rich in nutrients for growing A. platensis that could be tapped into aquifers means they are exposed to coal mining, contributing to processes of purification and bioremediation of contaminated waters carboniferous materials.

Reverse osmosis is currently the most promising method for addressing freshwater scarcity in numerous nations, enabling the production of drinkable water for human consumption. This process, however, generates a byproduct stream, known as desalination concentrate (DC), that is enriched with high concentrations of salts such as Na+ and Cl−, moderate levels of SO42−, Mg2+, Ca2+ and K+ and trace levels of Si, Fe3+, NO3− and PO43−, which can be suitable and valuable for microalgal metabolism and growth. Salt concentration in DC can significantly influence microalgal growth via effects through osmotic shock, salt stress and cellular ionic ratios. Under certain conditions, these salinity changes can have a positive impact on microalgal metabolism, such as the synthesis of lipophilic compounds that include lipids, fatty acids and carotenoids. This mini‐review aims to provide up‐to‐date information of recent studies conducted towards the use of DC as a potential substrate for microalgal cultivation as well as to summarize the response mechanism of microalgae when cultured in DC. Several laboratory‐based studies have examined the effect of different DC concentrations on the biochemical composition of microalgae grown either in photobioreactors or in raceway ponds. These studies have uncovered significant effects of DC on the synthesis of proteins, amino acids and phycocyanin in freshwater species like Chlorella vulgaris and Arthrospira platensis, where DC tends to hinder these processes. Conversely, experiments with halophilic Dunaliella salina and marine Nannochloropsis gaditana have demonstrated that increasing DC concentration can positively influence the production of β‐carotene, lipids and specific saturated fatty acids (C16:0 and C18:0), suggesting that these species can adapt to a broader range of DC salinities. Cultivating salinity‐tolerant microalgae in DC would greatly reduce the production cost of algal‐based products, offering a promising approach to enhance the profitability of desalination and microalgal industries. © 2023 Society of Chemical Industry (SCI).
