| 英文摘要 | Microalgae have been identified as a promising option for simultaneous bioremediation of wastewater and production of valuable biomass (i.e., high value-added products and bioenergy). This study investigated the potential for applying microalgae-microalgae consortia to treat biogas slurry with high ammonia nitrogen (156.60 +/- 1.32 mg & sdot; L - 1 ) and pH (9.53 +/- 0.23) value. Different co-culture systems were established using various microalgae (i.e., Chlorella vulgaris, Chlorella pyrenoidosa and Tetradesmus obliquus ). The results indicated that cocultivation of microalgae significantly enhanced the tolerance of microorganisms to biogas slurry and improved nutrient removal efficiencies. Particularly, C. vulgaris - C. pyrenoidosa - T. obliquus co-cultivation system performed best, leading to high removal efficiencies of 80.23 +/- 0.45 %, 80.40 +/- 0.57 %, and 68.54 +/- 0.20 % for total nitrogen (TN), ammonium (NH 4 + -N) and total phosphorus (TP), respectively. Particularly, synergistic effects of this co-culture system on the increase in biomass growth was also observed, with dry weight of 0.410 +/- 0.0071 g & sdot; L - 1 . The highest extracellular polymeric substances (EPS) content (63.97 +/- 0.21 mg & sdot; L - 1 ) of C. vulgaris - C. pyrenoidosa - T. obliquus highlighted the crucial role of microalgal co-cultivation in stimulating the formation of microalgal aggregates, thereby enhancing the adaptability of microalgae to stressful environment associated with biogas slurry. Furthermore, this co-cultivated system facilitated the production of high value-added products, with protein and lipid contents of 37.53 +/- 0.83 % and 31.33 +/- 0.78 %, respectively. Fatty acid analysis revealed that co-culture-derived biodiesel could fulfill the standard specifications, reinforcing the fact that microalgae biomass could serve as a sustainable feedstock for biodiesel production. The findings of this study shed a light on the application potential of a microalgae-microalgae co-culture system for effectively treating biogas slurry. |
