Microalgae are pervasive organisms regarded as conservative alternatives for the sustainable synthesis of various high-value-added bio-products to replace depleting fossil fuels and reduce CO2 emissions. However, microalgae biorefinery is still very far from being commercially viable due high costs, intensive energy requirements, low availability biomass biomolecules. In this review, current status discussed by establishing efficiency green biotechnology in producing wastewater diverse derived biorefinery. addition, aspects involved production bulk chemicals value-added biorefinery, including their roles environmental protection promotion an integrated circular bio-economy elucidated. Lastly, challenges facing recommendations guide future research toward cost-effective, more efficient, presented.

Nutrient Removal by Algae-Based Wastewater Treatment

Current Pollution Reports, Год журнала: 2022, Номер 8(4), С. 369 - 383

Опубликована: Авг. 18, 2022

Abstract Algae cultivation complements wastewater treatment (WWT) principles as the process uptakes nutrients while assimilates CO 2 into biomass. Thus, application of algae-based WWT is on upward trajectory more attention for recovery and capture reducing its economic challenge in circular economy concept. However, complexity algal ecological characteristics induces techno-economic challenges industry implementation. Algae-based relies totally ability algae to uptake store Therefore, removal efficiency proportional biomass productivity. This mechanism limits applications low nutrient concentration wastewater. The hydraulic retention time (HRT) significantly long (i.e. > 10 days), compared a few hours bacteria-based process. Phototrophic are most used studies well pilot-scale trials. Application phototrophic faces supply illumination. Collectively, significant landscape required has limited organic removals, which require pretreatment wastewaters before flowing can be connection with remove partial capturing . Future research should strive achieve fast high growth rate, strong environmental tolerance species, simple downstream processing high-value There also clear urgent need systematic analysis both carbon credit assessment values facilitate identification prioritisation barriers lower cost WWT.

Influence of Carbon Sources on Biomass and Biomolecule Accumulation in Picochlorum sp. Cultured under the Mixotrophic Condition

International Journal of Environmental Research and Public Health, Год журнала: 2022, Номер 19(6), С. 3674 - 3674

Опубликована: Март 19, 2022

The major downfalls of the microalgal biorefinery are low volume high value product accumulation, biomass productivity and cultivation costs. Here, we aimed to improve industrially relevant Picochlorum sp. BDUG 100241 strain. growth was investigated under different cultivations conditions, including photoautotrophic (with light), mixotrophic (1% glucose, with light) heterotrophic without light). Among them, BDUG100241 showed highest in condition. Under (1%) carbon sources' supplementation, sodium acetate, glycerol, citric acid methanol, tested. acetate found be most suitable source for growth, (1.67 ± 0.18 g/L) biomolecule productivity. From concentrations (0, 2.5, 5.0, 7.5 10 tested, maximum production 2.40 0.20 g/L 95 5.00 mg/L/d measured from acetate. total lipid (53.50 1.70%) carotenoids (0.75 0.01 µg/mL) contents were observed at concentration 5.0 as a source, respectively. In conclusion, condition containing yield accumulation compared other organic sources.
