Evaluation of flocculation induced by pH increase for harvesting microalgae and reuse of flocculated medium
TLDR
This study revealed that the microalgal biomass concentrations and released polysaccharide from microalgae could influence the flocculation efficiencies, and neutralizing pH and then supplementing nutrients allowed the flocculated medium to maintain an approximate growth yield to that of the fresh medium in algal cultivation.About:

Development of a harvesting technique for large-scale microalgal harvesting for biodiesel production
TL;DR: In this article, different harvesting techniques were assessed under a single domain to identify the most suitable one for large-scale harvesting of green microalgae for biodiesel purpose, and pH-induced flocculation was found to be efficient, cost-effective and eco-friendly as the supernatant can be reused as growth medium by resupplementing the nutrients and adjusting the pH.
Journal ArticleDOI
Cross-study analysis of factors affecting algae cultivation in recycled medium for biofuel production
TL;DR: It is found that algae taxa can have the greatest influence, while the harvesting method is less influential on growth outcomes, and this meta-analysis provides a tool for algae cultivation decision-making when medium reuse is an important driver.

Inhibition of Alkaline Flocculation by Algal Organic Matter for Chlorella vulgaris
Dries Vandamme,Annelies Beuckels,Eric W. Vadelius,Orily Depraetere,Wim Noppe,Abhishek Dutta,Imogen Foubert,Lieve M.L. Laurens,Koenraad Muylaert +8 more
TL;DR: In batch cultivation, flocculation was increasingly inhibited over time and mainly influenced by changes in medium composition, rather than biological changes at the cell surface, leading to an increased flocculant demand over time.
