“…It is documented that determining the strategies that provide the best performance in harvesting, and after-harvesting stages are of paramount importance in achieving the commercially feasible feedstock production process [20]. The downstream technologies generally include the best harvesting and after-harvesting methods without having qualitative damages to algal biomass and/or lipid content [20,50,51].…”

“…Harvesting is an important stage in the feedstock production process that requires to be investigated carefully throughout an integrated approach [49,51]. Accordingly, establishing the strategies that provide the best performance without qualitative damages to FA profiles, biomass, and lipid contents is crucial in implementing successful feedstock production [51]. Some strategies have been developed for algal biomass recovering, which the major ones include membrane filtration, centrifugation, and coagulation [124] Flocculation is a convenient harvesting strategy for recovering large volumes of algal biomass [169].…”

“…Table 1 shows a list including studies about increases in lipid and/or growth rate in microalgae, brief findings of which are given presently. Among the considered approaches, establishing the strategies that provide the best performance in the harvesting stage without having qualitative damages to microalgae biomass and/or lipid content is also important in the successful implementation of the feedstock production process [51]. For instance, Liu et al [52] applied magnetite nanoparticles (nano-Fe3O 4 coated) for the harvesting of C. pyrenoidosa and S. obliquus strains, and reported that this harvesting method did not reduce the lipid content in these species.…”

“…For instance, Liu et al [52] applied magnetite nanoparticles (nano-Fe3O 4 coated) for the harvesting of C. pyrenoidosa and S. obliquus strains, and reported that this harvesting method did not reduce the lipid content in these species. Very few studies have been performed on harvesting and after-harvesting stages, although these stages should be taken into consideration for improving lipid productivity in the feedstock production process [50,51]. In one of such studies, Menegazzo et al [49] reviewed the culture conditions for various algae species and their influence on the separation of microalgae biomass, lipid content, including biomass thickening methods, and methods of biomass depletion, the methods of cellular disruption and lipid extraction.…”

Microalgae have received widespread interest owing to their potential in biofuel production. However, economical microalgal biomass production is conditioned by enhancing the lipid accumulation without decreasing growth rate or by increasing both simultaneously. While extensive investigation has been performed on promoting the economic feasibility of microalgal-based biofuel production that aims to increase the productivity of microalgae species, only a handful of them deal with increasing lipid productivity (based on lipid contents and growth rate) in the feedstock production process. The purpose of this review is to provide an overview of the recent advances and novel approaches in promoting lipid productivity (depends on biomass and lipid contents) in feedstock production from strain selection to after-harvesting stages. The current study comprises two parts. In the first part, bilateral improving biomass/lipid production will be investigated in upstream measures, including strain selection, genetic engineering, and cultivation stages. In the second part, the enhancement of lipid productivity will be discussed in the downstream measure included in the harvesting and after-harvesting stages. An integrated approach involving the strategies for increasing lipid productivity in up- and down-stream measures can be a breakthrough approach that would promote the commercialization of market-driven microalgae-derived biofuel production.
