Cultivation of microalgae on liquid anaerobic digestate for depollution, biofuels and cosmetics: a review

Microalgae Cultivation on Anaerobic Digestate of Municipal Wastewater, Sewage Sludge and Agro-Waste

Microalgae are fast-growing photosynthetic organisms which have the potential to be exploited as an alternative source of liquid fuels to meet growing global energy demand. The cultivation of microalgae, however, still needs to be improved in order to reduce the cost of the biomass produced. Among the major costs encountered for algal cultivation are the costs for nutrients such as CO₂, nitroge...

Sustainable Cultivation of Microalgae using Diluted Anaerobic Digestate as a Nutrient Medium Algae-Based Systems

In this study, the cultivation of two microalgal species using anaerobic digestate as a nutrient medium was investigated. Several pretreatment methods were applied to the anaerobic digestate including hydrogen peroxide treatment, filtration using polyester filter bags, and supernatant extraction; the latter proved to be the simplest and most effective method in reducing the turbidity and COD of...

Microalgae cultivation on wastewater digestate: β-estradiol and 17α-ethynylestradiol degradation and transformation products identification.

Selenastrum capricornutum and Chlamydomonas reinhardtii were tested for possible biodegradation of the hormones β-estradiol (E2) and 17α-ethinylestradiol (EE2) when cultured in anaerobic digester centrate (ADC). Neither ADC nor the hormones had a negative or toxic effect on the microalgae growth but enhanced it. E2 and EE2 biodegradation was evaluated under different culture conditions. After 7...

Investigation of microalgae cultivation and anaerobic codigestion of algae and sewage sludge for wastewater treatment facilities

Biofuels from microalgae.

Microalgae are a diverse group of prokaryotic and eukaryotic photosynthetic microorganisms that grow rapidly due to their simple structure. They can potentially be employed for the production of biofuels in an economically effective and environmentally sustainable manner. Microalgae have been investigated for the production of a number of different biofuels including biodiesel, bio-oil, bio-syn...
