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

New opportunities for agricultural digestate valorization: current situation and perspectives

“…Experimental results suggest that liquor digestates can be used to support algal growth. Nevertheless, it is important to notice that digestate has been used after pretreatment including solid/liquid separation, macro or micronutrient adjustment/supplementation 47,48 and dilution. The vast majority of available data were obtained by indoor batch tests under controlled (although different among references) temperature, illumination, CO 2 supply and mixing conditions.…”

Potential of Chlorella vulgaris culture for waste treatment from anaerobic biomass biodigestion at the Piaszczyna (Poland) integrated facility

“…Similar effectiveness of treatment might be achieved also for anaerobic digestate effluent (Wang et al 2010a, Pei et al 2017, Jiang et al 2018. The Chlorella strains are also able to capture and store the bioavailable fraction of phosphorus when cultivated in the presence of the anaerobic digestate which contribute to the overall treatment of the digestate (Marcilhac et al 2015).…”

“…It is hard to directly compare the microalgal productivity in under conditions and with different anaerobic digestate composition. The biomass yield from 0.4 to 0.8 g Á L À1 was achieved on livestock wastes (De la No€ ue and Basseres 1989, Marcilhac et al 2015). Other research reports the microalgae productivity on media composed of or containing digestate in range from 29 mg Á L À1 Á d À1 up to 0.26 g Á L À1 Á d À1 (De la No€ FIG.…”
