BACKGROUND: In this study, five microalgal species (Chlorella vulgaris, Chlorococcum sp. GD, Parachlorella kessleri TY, Scenedesmus quadricauda, and Scenedesmus obliquus) were cultivated in batch mode to evaluate their respective potential for the treatment of real aquaculture wastewater from a fishery. Subsequently, the microalga with the best performance was cultivated with different initial inoculation concentrations to evaluate the effect of initial inoculation on pollutant removal efficiency. RESULTS: When real aquaculture wastewater was inoculated with exogenous microalgae, the growth of both indigenous microalgae and bacteria was significantly inhibited. Pollutant removal was closely related to exogenous inoculationof microalgae. Parachlorella kessleri TY had high growth potential and pollutant removal capability in aquaculture wastewater, compared with the other four microalgae. When the wastewater was inoculated with low biomass concentrations of P. kessleri TY (50-100 mg L −1 ), it grew well and degraded most of the encountered pollutant. In particular, P. kessleri TY with 100 mg L −1 of inoculation concentration removed 94.4% of COD, 96.2% of ammonium, 99% of nitrite, 94.3% of nitrate, and 95.6% of phosphorus after 3 days of cultivation. CONCLUSIONS: Both the screening for microalgal species and the regulation of initial inoculation concentrations are promising approaches to enhance pollutant removal efficiency from real aquaculture wastewater. Determination of water qualityTo determine the water quality, the microalgal suspension was centrifuged at 5000 rpm for 5 min and the supernatant J Chem Technol Biotechnol 2019; 94: 900-910 /jctb up to 94.4%, 96.2%, 99%, 94.3%, and 95.6% for COD, ammonium, nitrite, nitrate, and total phosphorus, respectively. In the remaining tested inoculation concentrations (25, 50, 200, and 400 mg L −1 ), 77.8-88.9% of COD, 54.2-86.1% of ammonium, 64.1-91.7% of nitrite, 57.1-85.7% of nitrate, and 53-81.4% of total phosphorus were removed from the aquaculture wastewater J Chem Technol Biotechnol 2019; 94: 900-910

“…Multi-trophic systems that involves the use of Chlorella sp. in combination with effective microorganism (EM) have also indicated capability of treating Lates calcifer aquaculture wastewater for recycling (Lananan et al 2014). Mycoalgae biofilm formed by combination of Mucor indicus and C. vulgaris on polymer matrix surface, converts excess nitrogen and phosphorus into microalgal biomass for fish consumption and at the same time purifying the aquaculture water for recirculation (Barnharst et al 2018).…”

Microalgae biomass is used in aquaculture as feed, growth enhancers and immunostimulants. Chlorella vulgaris is an important species with a good biomolecular composition. Commercially, it is one of the most commonly used microalga in aquaculture. Several studies confirmed its ability to improve nutrition, immunity, aquatic bioremediation, amelioration of stress, disease resistance of fish and inhibits bacterial quorum sensing when used appropriately. Despite claims of its benefits, C. vulgaris is reported to have unfavourable effects when incorporated in diets at higher inclusion levels. In addition, its rigid cell wall might restrict the access of digestive enzymes to the intracellular components for proper digestion and assimilation. Thus, this review discusses the role of C. vulgaris and its importance in aquaculture with emphasis on its environmental requirements, morphology, pigments, digestibility, dynamics on growth performance, antibacterial activity, bacterial quorum sensing, immunomodulatory effect, anti‐stress effect, gut microbiome, aquatic bioremediation and its safety as food or feed.

The study evaluates the phytoremediation capabilities of Acrostichum aureum in the treatment of shrimp farm effluent. The effluent parameters like Biochemical Oxygen Demand (BOD) (73%), Chemical Oxygen Demand (COD) (39%) and Nitrate (55%) were found reduced considerably during the treatment period of thirty days. The antioxidant concentrations of the plant were increased to cope up with the stress environment. Superoxide dismutase (SOD) in plants was increased to 70% during the treatment period. Peroxidase activity was also found to be increased from 0.02 to 0.26 mg/gFW. The increase in non-enzymatic antioxidants like chlorophyll indicated the health status of the plant during the treatment period.
