“…(a), the biomass increases in wastewater with algae and bacteria were 0.57 and 0.24 g L −1 , respectively, revealing that algae had much better performance in biomass yield than bacteria in wastewater remediation. The main reason is that microalgae acquired carbon dioxide from the atmosphere by photosynthesis and utilized inorganic carbon in wastewater while organic carbon was the only carbon source for bacteria . Therefore, different trophic modes largely contributed to the difference in the biomass yields of algae and bacteria.…”

“…Additionally, the cooperation between PAOs, EEs‐releasing bacteria, and microalgae realized the efficient recovery of nutrients from centrate wastewater. In previous studies, the contributions of PAOs to nutrients removal from wastewater have been widely reported . However, the relation between PAOs and microalgae in nutrients recovery still remains unclear.…”

BACKGROUND: Microalgae biotechnology is considered as a promising way to recover nutrients from centrate wastewater for value-added biomass production, but it is rarely adopted in a real-world application. Current study confirmed that carbon deficiency and suspended solids are two problems jeopardizing the microalgae-based wastewater remediation. In this regard, glycerol was added into centrate wastewater as exogenous carbon source and algal-bacterial cooperation for nutrients recovery assessment. RESULTS:The results showed that glycerol addition increased the biomass yield of algae from 1.54 to 2.58 g L −1 in 5-day culture and, at the same time, improved the removal efficiency of nitrogen and phosphorus, which were further assessed by pilot-scale experiments. Bacterial community analysis indicated that algal-bacterial cooperation involves carbon dioxide and oxygen exchange, phosphorus absorption, and solid organics degradation, forming a complementary nexus beneficial for wastewater treatment.CONCLUSION: Glycerol is proven to be a good carbon source for microalgae growth in the centrate wastewater. Additionally, the cooperation between microalgae and bacteria plays a key role in the nutrients removal during centrate wastewater. It is expected the technology and knowledge provided by current work can further promote the industrialization of microalgaebased wastewater remediation. Figure 6.

Aquaculture is an important industry providing high‐quality animal protein to humans, but it brings serious environmental pollutions, such as eutrophication of water bodies and the abuse of antibiotics. Microalgae cultivation, which can recover nutrients, release oxygen and yield value‐added biomass, has been studied intensively as a promising biotechnology for aquaculture wastewater treatment and fish diet production. Herein, we introduce a novel concept of applying microalgae biotechnology in aquaculture by integrating wastewater remediation, biomass harvesting and aquatic animals rearing systems. We review recent progress in aspects of value‐added algal species screening, algae cultivation systems design, nutrient recovery by algal–bacterial interactions, and biomass harvesting technologies. Finally, we discuss some problems, including bacterial contamination, unfavorable conditions in effluent and lack of technological assessment, which may hinder the application of microalgae biotechnology. It is expected that this paper could attract researchers' and technicians' attention to the microalgae‐based pollution control and promote the development of ecofriendly aquaculture. © 2020 Society of Chemical Industry
