Four microalgal strains, namely, Tetraselmis indica (T. indica), Scenedesmus abundans (S. abundans), Spirulina sp., and Nostoc muscorum (N. muscorum) were cultivated on four different wastewaters in 1000 ml photobioreactors with 750 ml working volume under 94.5 μmol m s light intensity for 14 days for phycoremediation of wastewaters and sustainable biodiesel production. These microalgal strains attained maximum biomass growth in the secondary treated sewage (STS). Maximum biomass yield (0.6533 g L) and lipid productivity (25.44 mg L d) for T. indica were achieved in STS. T. indica removed (63.6-78.24%) of nitrate, (60.90-65.97%) of phosphate, (61.01-80.01%) of ammonical nitrogen, and (71.16-85.70%) of total organic carbon (TOC) in all four wastewaters. The fatty acid methyl ester (FAME) profile of T. indica shows the presence of myristic acid (1.2%) pentadecylic acid (0.28%), palmitic acid (10.32%), oleic acid (34.59%), linoleic acid (12.38%), and eicosanoic acid (14.88%) in STS. This study demonstrates that T. indica is the most suitable microalgal species among the four microalgal strains selected for phycoremediation of wastewaters and higher biomass production for sustainable biodiesel production.

The increasing need for sustainable agricultural practices due to the overuse of chemical fertilizers has prompted interest in microalgae as biofertilizers. This review investigates the potential of microalgae as biofertilizers and phycoremediators within sustainable agroecosystems, addressing both soil fertility and wastewater management. Microalgae provide a dual benefit by absorbing excess nutrients and contaminants from wastewater, generating nutrient-rich biomass that can replace chemical fertilizers and support plant growth.

The current study investigated the enhancement of biomass in S. obliquus, using rice bran oil processing (RBOP) wastewater in different RBOP wastewater concentrations, while also aiming to produce biofuel and treat the wastewater simultaneously. The strain was grown in Blue Green-11 (BG11) media as well as RBOP wastewater at different wastewater concentrations with distilled water at 10%, 25%, 50%, 75%, and 100% under controlled experimental settings.

Qatar and other Gulf States have a diverse range of marine vegetation that is adapted to the stressful environmental conditions of seawater. The industrial wastewater produced by oil and gas activities adds further detrimental conditions for marine aquatic photosynthetic organisms on the Qatari coastlines. Thus, these organisms experience severe stress from both seawater and industrial wastewater.

Background: In recent decades the demand for freshwater has drastically increased as a consequence of population growth, economic development, climate change and pollution. Therefore, any strategy for wastewater treatment can play a role in alleviating the pressure on freshwater sources.
Results: In the present study an autochthonous microalgal pool (MP), isolated from a constructed wetland, was proposed as an alternative to the secondary treatment of an urban wastewater treatment system.
