Harvesting of oleaginous Chlorella sp. by organoclays

Microalgal biofuel revisited: An informatics-based analysis of developments to date and future prospects

“…nontoxic flocculants (e.g., organic polymers) have been intensively investigated but are too expensive for large-scale applications [50]. Autoflocculation by increasing the pH of the medium and electrolytic flocculation may be used to separate algae without the addition of chemicals and would be more economical than other harvesting techniques for marine microalgae [50,51].…”

“…Autoflocculation by increasing the pH of the medium and electrolytic flocculation may be used to separate algae without the addition of chemicals and would be more economical than other harvesting techniques for marine microalgae [50,51]. Moreover, unlike other harvesting technologies, the cost contribution to algal lipid from electrolytic flocculation was unaffected by the concentration of algae in the algal water [52].…”

Harvesting of Microalgae by Means of Flocculation

“…So far, however, only a few studies have explored the potential of clays for harvesting microalgae. One study explored the use of synthetic organoclays with specific surface properties for flocculating Chlorella (Lee et al 2013b). Farooq et al (2013) successfully demonstrated aminoclay harvesting of Chlorella vulgaris and Nannochloris oculata.…”

Lipid extraction from microalgae cell using UV–Fenton-like reaction

“…KR-1) was obtained from the Korea Institute of Energy Research (KIER). Cultivation conditions were the same as in previous studies (Lee et al, 2013;Kim et al, 2014). A final cell density and lipid content was 1.7 g/L and 35% lipid content, respectively.…”
