Anaerobic digestates are useful nutrient sources for microalgae cultivation: functional coupling of energy and biomass production

Bioprospecting of microalgae for integrated biomass production and phytoremediation of unsterilized wastewater and anaerobic digestion centrate

“…2 and 4) and final density of the cultures (Fig. 5a) observed in this study are either similar or lower than the values reported earlier for Chlorella and Scenedesmus species cultivated in domestic wastewater or AD effluent (Bjornsson et al 2013;de Bashan et al 2008;Li et al 2011;McGinn et al 2012;Park et al 2010Park et al , 2011bWang et al 2010). However, the experimental design and cultivation conditions in the current study were quite different from the conditions applied in the studies mentioned above (e.g., continuous light (de Bashan et al 2008;Li et al 2011;Park et al 2011b), higher temperature (de Bashan et al 2008;Li et al 2011;Wang et al 2010), and CO 2 injections (Bjornsson et al 2013;Li et al 2011).…”

“…important for robust growth in the unsterilized wastewater containing a variety of contaminants. Previous studies have indeed reported on the potential application to wastewater and tolerance to ammonia for both C. sorokiniana (de Bashan et al 2008;Kim et al 2013a;Kobayashi et al 2013;Ogbonna et al 2000;Tuantet et al 2013Tuantet et al , 2014 and Scenedesmus species (Bjornsson et al 2013;Dickinson et al 2013;Gantar et al 1991;McGinn et al 2012;Park et al 2010), although in most of those cases, the wastewater was sterilized or filtered through 0.22-μm filter to remove bacteria and other indigenous microorganisms prior to algal cultivation. Another factor contributing to robustness of the C. sorokiniana and Scenedesmus species in wastewater may be the tough structure of their cell wall.…”

Control of nitrogen behaviour by phosphate concentration during microalgal-bacterial cultivation using digestate

“…Other technologies requiring less energy and chemical additions may be a solution for nutrient recovery, in particular treatment and valorisation of N and P with microalgae (Bjornsson et al, 2013). Indeed, digestate can be an interesting culture medium for microalgae cultivation, as for higher plants.…”

Waste to Energy from Flue Gas of Industrial Plants to Biodiesel: Effect of CO2 on Microalgae Growth

“…In this regard, various studies were conducted for use municipal, agricultural and industrial waste for cultivation of microalgae [34]. However, the prior dilution of waste resources is necessary to enhance the productivity and nutrient utilization rate of microalgae [35]. The results of our study suggest that Chlorella vulgaris is more suitable species for management of CO 2 from flue gas and production of valuable products (e.g.…”
