Algae and aquatic biomass: reactors and remediation
Towards the Phycoremediation of Digestate: Physiological Analysis of Algal Growth in an Artificial and Pre-treated Digestate
Short Introductive summary
Phycoremediation of wastewaters contributes to the mitigation of global warming while recycling nutrients and carbon into high value algal biomass. Digestate is a wastewater produced during the anaerobic fermentation of biomass into biogas and, despite its richness in nutrients, its toxicity makes it difficult to use as growing medium for microalgae. Our study investigated the phycoremediation of digestate from a physiological point of view, using first an artificial digestate and then a pre-treated digestate. Three promising species (T. obliquus, C. reinhardtii, A. protothecoides) were selected for the remediation of the wastewater and several experiments were carried out to enhance biomass production and remediation yield. Despite a digestate concentration higher than 7% was deleterious for the algae tested, different growing conditions, such as immobilization, were examinated to improve the sustainability and efficiency of the process.

Presenter's biography
I am a plant biotechnologist with a great passion for environmental sustainability and microalgae biotechnology. Currently I'm working as PhD student (UNIVPM) on microalgae and their uses as biostimulants and also to phytoremediate wastewaters.
