“…is exposed to salinity stress, fatty acid profiles were lower than those in this study where C16:0 was 23.30%, C18:0 was 1.71% and C18:3 was 11.12%. A similar FAME profile Shekh et al (2016).…”

In this study, mixed microalgal culture dominated by Chlorella vulgaris and Scenedesmus armatus was grown in Anaerobic Liquid Digestate (ALD) at different NaCl concentrations ranging between 0 and 100 mM. Highest lipid and carbohydrate amounts were observed as 38.4 and 36.2%, respectively, when the salinity was 50 mM NaCl. However, the protein content was drastically decreased to 12.8% with increased NaCl concentration. Furthermore, the algal biomass was subsequently decreased along with the total chlorophyll amount with increased NaCl concentration. Algal species showed diverse response to salinity stress and demonstrated a cost-effective approach towards the cultivation of mixed microalgae within digestate and provided insight that ALD and/or other wastewaters can be diluted with seawater instead of tap water in the future studies. This study could be further converted into biofuels because of an increase in lipid content along with the digestate treatment, which will help to valorize ALD and bring into economy.

“…The higher SV results in the higher percentage of free fatty acids which may lead to soap formation and lower yield of biodiesel (Ibeto et al, 2011). The average SV was >239 mg KOH/g biodiesel which was much higher than values (170-217 mg KOH/g biodiesel) have been reported for pure algal biodiesel (Shekh et al, 2016;Talebi et al, 2013;Yang et al, 2016). CP relates to biodiesel cold properties and defines the onset crystallisation temperature of the biodiesel.…”

“…S14 may be attributed to combinatory effects of salinity (2.5 g/L NaCl) and light intensity (100 µmol photons m −2 s −1 ). Shekh et al [ 29 ] reported an accumulation of PUFA (71.91%), SFA (16.66%) and MUFA (13.19%) in Chlorella sp. cultivated under high light intensity (100 µmol photons m −2 s −1 ) and low salinity (12.5 ppm).…”

Microalgae is a rich source of polyunsaturated fatty acid. This study was conducted to identify and isolate microalgal strain with the potentials for producing polyunsaturated fatty acids (PUFAs) and determine its cytotoxic effect on some cancer cells. The algal strain (Chlorella sp. S14) was cultivated using modified BG-11 media, and algal biomass obtained was used for fatty acid extraction. Gas chromatographic–mass spectrometry was used to identify and quantify the levels of the fatty acid constituents. The total content of monounsaturated fatty acids (1.12%) was low compared to polyunsaturated fatty acids (PUFAs) (52.87%). Furthermore, n-3 PUFAs accounted for (12.37%) of total PUFAs with the presence of α-linolenic acid (2.16%) and cis-11,14,17-eicosatrienoic acid (2.16%). The PUFA-rich extract did not exhibit a cytotoxic effect on normal cells. Treatment with the PUFA-rich extract (150 µg/mL) significantly reduced cell viability in MCF-7 (31.58%) and A549 (62.56%) cells after the 48 h treatment. Furthermore, treatment of MCF-7 with fatty acid extracts (125 and 150 µg/mL) showed a significant reduction in MDA levels, increase in catalase activities and decrease in GSH level compared to untreated cells. However, a slight decrease in MDA level was observed in A549 cells after the 48 h treatment. There are no significant changes in catalase activities and GSH level in treated A549 cells. However, a slight reduction of NO levels was observed in treated MCF-7 and A549 cells. These results indicate the potentials of PUFA-rich extracts from Chlorella sp. S14 to reduce viability and modulate redox status in A549 and MCF-7 cells.
