“…The fatty acid compositions of Chlorella sp. under citric acid were 16:0, 20:5 and 22:5 at 18%, 25% and 17%, respectively, of total fatty acids (Li et al, 2013). The predominant fatty acids composed of C16 and C18 chain length present in the Chlorella strains are appropriate for the biofuel and biodiesel application.…”

“…For example, rates of nitrogen and phosphorus removal of C. sorokiniana were 50-68 and 1.4-2.6 mg/L respectively, from poultry manure ADE (Singh et al, 2011). Removal of TN, TP and NH 4 -N of Chlorella vulgaris were 99%, 96% and 100% from 10% citric acid effluent (Li et al, 2013). TN, TP and NH 4 -N removals of Chlorella sp.…”

“…1). The maximum biomass production of C. sorokiniana was measured at 313-387 mg/L in poultry ADE (Singh et al, 2011) while various C. vulgaris strains yielded 0.52-0.765 g/L in citric acid effluent (Li et al, 2013). The biomass of C. sorokiniana CS-01 under both 10% ADE and BBM conditions reached 280 mg/L (cell density: 50-60 million cells/mL) at day-16 before decreasing in cell number.…”

“…Nutrient uptake from different manure-based ADE products and industrial effluents have been evaluated for production of biomass, lipids, carbohydrates and proteins in Chlorella species. Effluent sources have (1) poultry litter (Singh et al, 2011); (2) citric acid effluent produced by fermentation (Li et al, 2013); (3) carpet mill industrial effluent and (4) animal manure from different sources Huo et al, 2012;Kebede-Westhead et al, 2004;Mulbry et al, 2008;Zhou et al, 2012).…”

Chlorella sorokiniana CS-01, UTEX 1230 and UTEX 2714 were maintained in 10% anaerobic digester effluent (ADE) from cattle manure digestion and compared with algal cultivation in Bold's Basal Medium (BBM). Biomass of CS-01 and UTEX 1230 in ADE produced similar or greater than 280mg/L after 21days in BBM, however, UTEX 2714 growth in ADE was suppressed by more than 50% demonstrating a significant species bias to synthetic compared to organic waste-based media. The highest accumulation of protein and starch was exhibited in UTEX 1230 in ADE yielding 34% and 23% ash free dry weight (AFDW), respectively, though fatty acid methyl ester total lipid measured less than 12% AFDW. Results suggest that biomass from UTEX 1230 in ADE may serve as a candidate alga and growth system combination sustainable for animal feed production considering high yields of protein, starch and low lipid accumulation.

“…Orpez, R. et al [34] found that Botryococcus braunii cultivated in sewage (secondarily treated) as tertiary treatment unit can acquire good performance with 17% lipid accumulation. There were also other researches suggested that the industrial wastewater can be subjected to dilution or mixing with organic compounds will promote the growth of microalgae [35,36].…”

Abstract. Microalgae have great potential as the feedstock of renewable energy. Nevertheless, the high cost of microalgae cultivation hinders its development economically, so inexpensive cultural mediums are supposed to be found for the large-scale application of microalgae. Wastewater contains large amount of organic and inorganic compounds, which provides nutrition for the cell growth and lipid accumulation of microalgae. Here we will review the systems of microalgae cultivation and utilize wastewater as a feedstock for biodiesel production. It illustrates that the integration of microalgae cultivation and wastewater treatment could improve water quality and accumulate lipid simultaneously.

Waste organics conversion to algal lipid is environmentally friendly and it promotes sustainability. Achieving high-lipid content in cells is crucial to the economic feasibility of algal lipid production and collection. Here, a phagotrophic microalga Ochromonas danica was grown on waste ketchup and then stimulated to accumulate high-lipid content using glycerol and acetate. Individually, glycerol and acetate could increase lipid synthesis. Sequential glycerolthen-acetate addition was more effective; for an O. danica culture with 0.25 g L −1 cells, the intracellular lipid content was increased to 70-80% (w/w) in 6-12 hours. However, acetate added at >1 g L −1 damaged cells. For high-density (25 g L −1 ) fermentations, glycerol and acetate addition strategies were evaluated to overcome this inhibition. Results indicated that glycerol could be added in batches or continuously as long as the amount was sufficient to satisfy the glycerol consumption rate of 6 mg (g cells-hour) −1 while acetic acid needed to be added continuously, optimal at a rate of 0.27-0.30 g hour −1 or 12-14 mg (g cells-hour) −1 . Intracellular lipid content could reach 70-80% after 2-day supplementation of glycerol and acetic acid. The methods of glycerol/ acetate additions developed here enhance algal lipid production and enable effective conversion of organic wastes to algal lipids as sustainable bioproducts.Keywords Phagotrophic microalgae Á Algal lipid Á Ochromonas Á Glycerol Á Acetic acid Á Acetate sensitivity J Am Oil Chem Soc (2019) 96: 231-238.
