“…2-step hybrid systems including optimization of growth in a rich medium and then transfer of part of the culture under conditions favoring lipid production have also been developed (Aziz et al, 2020). Li et al (2019) has reported that the cost of microalgae production processes was strongly affected by the cost of the raw materials used. An alternative eco-friendly solution to reduce these costs could come from the use of wastewater as nutrient sources.…”

Research on lipid production in microalgae, especially to target biofuels, has been widely published in recent decades. This literature is mostly focused on the optimization of culture conditions, metabolic engineering, biorefinery and downstream processes. At the lab scale, lipid production is very promising concerning biofuels production based on microalgae due to their high lipid content. However, the accumulation of knowledge associated with the development of processes and technologies for the production of biomass and associated lipids has so far not achieved the hoped-for commercial success due to still too expensive operating costs compared to fossil fuels. This review aims to present the influence of various abiotic factors on the accumulation of lipids and lipid profile in microalgae, such as the depletion of the culture medium, temperature and light, but also most innovative like the induction by hormones. Other optimization procedures and the use of wastewater to improve the cost-viability are discussed in perspective.

“…For instance, Gupta et al [11] found autoclaving municipal wastewater increased TN and TP concentrations, while COD and NH 4 + -N concentrations decreased. Li et al [45] and Li et al [46] observed an increase in COD, TN, and TP concentrations, compared to a decrease in NH 4 + -N concentration after autoclaving highly concentrated municipal wastewater and cooking cocoon wastewater, respectively. These studies used autoclaving wastewater for microalgae growth, biomass production, and nutrient removal.…”

Microalgae have the ability to utilize nutrients present in wastewater and generate biomass that is abundant in carbohydrates, lipids, and proteins. The ability of microalgae to integrate wastewater management and biofuel production makes them a promising solution for enhancing environmental sustainability. The objective of this study was to assess the potential of local microalgae, Scenedesmus sp., to simultaneously remediate wastewater and produce lipids. The microalgae were cultivated in anaerobically digested brewery effluent, both sterilized and non-sterilized, to evaluate their phycoremediation and lipid production capabilities. The phycoremediation study was investigated by measuring chemical oxygen demand (COD), total nitrogen (TN), ammonium–nitrogen (NH4+-N), and total phosphorus (TP) removal from brewery effluent. Lipids were extracted from microalgal biomass without and with pretreatment methods, such as microwave, autoclave, osmotic stress, oven heating, and HCl digestion in a water bath, to enhance lipid extraction. Results indicate that Scenedesmus sp. achieves higher biomass production in non-sterilized brewery effluent compared to sterilized brewery effluent. Conversely, it attains higher lipid accumulation in sterilized brewery effluent compared to non-sterilized brewery effluent. Scenedesmus sp. also attained a higher removal of TP (69.32%) and COD (77.78%) in non-sterilized effluent, but TN (96.14%) in sterilized brewery effluent. The removal of NH4+-N was nearly 100% in both effluents. The maximum lipid content obtained was 14.79%, which was enhanced by 39.06%, 23.89%, 15.81%, 11.61%, and 4.78% after microwave, HCl digestion, autoclave, osmotic, and oven heating pretreatments, respectively. The findings of this study demonstrate that local microalgae have a great potential for wastewater remediation with lipid production using appropriate pretreatment methods.

“…Li et al. (2019) investigated the suitability of using cooking cocoon wastewater (CCW), a by‐product of many silk producers, to cultivate microalgae, thus removing usable nutrients from the wastewater. Although photosynthetic growth was not affected under raw or autoclaved CCW conditions when compared to the control, both biomass production and nutrient removal efficiency increased under raw and autoclaved CCW conditions.…”
