Using coagulation–flocculation to harvest Chlamydomonas reinhardtii: Coagulant and flocculant efficiencies, and reuse of the liquid phase as growth medium

Coagulation–flocculation is an efficient, economic, and scalable process suitable for harvesting microalgae. The study tested the effectiveness of 11 agents (chitosan and 10 commercial, industrially available reference products) for harvesting Chlamydomonas reinhardtii, a model microalga. The highes...

Description
Summary:Coagulation–flocculation is an efficient, economic, and scalable process suitable for harvesting microalgae. The study tested the effectiveness of 11 agents (chitosan and 10 commercial, industrially available reference products) for harvesting Chlamydomonas reinhardtii, a model microalga. The highest efficiencies (>95%) with the lowest dose (
