“…A cooperative interaction allows each individual to benefit from the activity of the other, while in competitive interaction one species benefits at the expense of the other by reducing fitness, by exploitation or parasitism. A microalgae consortium containing the four strains Chlorella, Chlamydomonas, Scenedesmus, and Neochloris was co‐cultivated and found capable of removing more than 98% of nutrients from dairy wastewater . Sathish and Sims co‐cultured two dominant microalgae species Chlorella sp.…”

In response to the energy crisis, global warming and climate change, microalgae have received a lot of attention as a promising feedstock for the production of biofuels. However, microalgal biofuels are still unaffordable due to low productivity and their substantial requirements in capital investment and operation costs. Much original research regarding the various microalgal cultivation strategies has been reported, in an attempt to promote microalgal biofuel production. However, current literature indicates the fragmented nature of information available regarding the strategies for the improvement of microalgal production for biofuel conversion. From a systematic perspective, this review highlights the main microalgal cultivation strategies for the achievement of improved biomass and biofuel productivity. It first discloses the current state of microalgal production as a biofuel feedstock, giving general introduction to the topic. Subsequently, it summarizes the current microalgae cultivation technology. Microalgal cultivation strategies are then discussed systematically, including integration with wastewater treatment and CO2 mitigation, batch vs. semi‐continuous vs. continuous culture, two‐stage continuous cultivation, co‐culture, stress culture, and microalgal cultivation with harvest water recycling. Finally, concluding remarks are put forward. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd

“…A volumetric productivity of 11,000 L/ha/year is postulated based on the maximum lipid yield (Woertz et al 2009). Hena et al (2015) also demonstrated nutrient removal of 98% from treated dairy farm wastewater using a consortium of native strains while achieving a final lipid content of 17%.…”

“…The amounts of N and P required for algal growth can be estimated by mirroring the normal intracellular C:N:P ratio, known as the Redfield ratio (Kesaano and Sims 2014). Generally, many factors such as N and/or P limitation, silicon limitation, control of pH, and low temperature can be used to increase oil accumulation, although their effectiveness depend on the strain and other culture conditions (Hena et al 2015). Most municipal wastewater is known to have C:N:P ratios that differ substantially from Redfield values, resulting in N limitation and concomitantly leading to increased lipid production at the expense of growth (Griffiths and Harrison 2009;Kesaano and Sims 2014).…”

Despite years of concerted research efforts, an industrial-scale technology has yet to emerge for production and conversion of algal biomass into biofuels and bioproducts. The objective of this review is to explore the ways of possible integration of biology, ecology and engineering for sustainable large algal cultivation and biofuel production systems. Beside the costs of nutrients, such as nitrogen and phosphorous, and fresh water, upstream technologies which are not ready for commercialization both impede economic feasibility and conflict with the ecological benefits in the sector. Focusing mainly on the engineering side of chemical conversion of algae to biodiesel has also become obstacle. However, to reduce the costs, one potential strategy has been progressing steadily to synergistically link algal aquaculture to the governmentally mandated reduction of nitrogen and phosphorous concentrations in municipal wastewater. Recent research also supports the suppositions of scalability and cost reduction. Noticeably, less is known of the economic impact of conversion of the whole algae-based biorefinery sector with additional biochemical and thermochemical processes and integration with ecological constraints. This review finds that a biorefinery approach with integrated biology, ecology, and engineering could lead to a feasible algal-based technology for variety of biofuels and bioproducts. which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made.

“…for the treatment of raw wastewater from effluents of the tannery industry for nutrients removal 11,12 . Furthermore, studies show that microalgae consortium is more efficient in the removal of pollutants and nutrients, like nitrogen, phosphorus, and ammonium, from wastewater when compared to individual microorganisms applied for the treatment local municipal wastewater 13 and dairy farm 14 . In this context, investigations about the isolation of the microalgae species present in the consortium in the environment are searched.…”

Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather) for the treatment of wastewater of a tannery processing wet-blue leather to finished leather. It was initially evaluated the growth of the microalgae consortium in the three effluents diluted in 50% distilled water: raw effluent (50RE50W), effluent after primary coagulation/flocculation (50PE50W), and effluent after primary and secondary biological treatment (50BE50W). After 16 days of cultivation, the 50PE50W presented the highest HIGHLIGHTS • The microalgae consortium was able to grow in tannery effluents.• The culture achieved higher growth in the diluted raw effluent.
