Comparison of the Advantages and Disadvantages of Algae Removal Technology and Its Development Status

Water, Journal Year: 2023, Volume and Issue: 15(6), P. 1104 - 1104

Published: March 13, 2023

In recent years, the frequent outbreaks of cyanobacterial blooms have caused severe water pollution in many rivers and lakes at home abroad, endangering drinking safety human health. How to remove cyanobacteria from bodies safely, quickly, economically has attracted attention scientists. Currently, typical treatment methods for algae algae-bearing are physical, biological, chemical methods. The physical method removal is both symptoms root cause, but workload extensive, with high input costs, should not be used on a large scale. biological low-cost, efficiency slow unsuitable sudden bloom. can kill it easy cause secondary pollution. These relatively independent each other, so choice practical combination technologies essential algal bloom eutrophication management. This paper reviews current application status advantages disadvantages abroad; classifies them chemical, combined methods; provides an outlook future development direction technologies.

Review on microalgae protein and its current and future utilisation in the food industry

International Journal of Food Science & Technology, Journal Year: 2023, Volume and Issue: 59(1), P. 473 - 480

Published: July 5, 2023

Summary Microalgae, the photosynthetic microorganisms, open novel commercial opportunities for developing new products because of their abundance in protein, carbohydrates, pigments, vitamins and minerals. These microorganisms possess several advantages such as rapid growth, minimal land water requirements adaptability to various environmental conditions. As concerns arise regarding ability animal plant‐based sources meet future protein demands, researchers have turned attention microalgae like Spirulina Chlorella applications. Microalgae typically contain around 30% case few cyanobacteria it can reach up 55%–60%, surpassing content conventional sources. Numerous studies investigated utilisation algal biomass enhance a wide range food products, including cookies, bread, yoghurt, snacks, dairy alternatives soups. This comprehensive review aims provide systematic exploration its current industry.

Are native microalgae consortia able to remove microplastics from wastewater effluents?

Environmental Pollution, Journal Year: 2024, Volume and Issue: 349, P. 123931 - 123931

Published: April 4, 2024

Wastewater Treatment Plants (WWTPs) are potential sources of microplastics (MPs) in the aquatic environment. This study aimed to investigate wastewater-native microalgae consortia remove MPs from effluent two different types WWTPs as a dual-purpose solution for mitigation and biomass production. For that purpose, occurrence WWTP effluents was analysed over one year. were characterized terms morphology (microbead, foam, granule, irregular, filament film), colour size. The wastewater characterisation followed by removal MP loads, using native consortia, pre-adapted effluent. Microalgae evolved naturally through four assays, adapted seasonal conditions, such temperature, photoperiod, composition. present all samples, ranging 52 233 L−1. indicated predominance white transparent particles, with irregular shapes, mainly under 500 μm μFTIR analysis revealed 43% selected particles plastic, prevalence polypropylene (PP) (34%) polyethylene terephthalate (PET) (30 %). In experiments, substantial production achieved (maximum 2.6 g L−1 (d.w.)), successful MPs, 31 ± 25% 82 13%. These results show growth efficiently promotes reducing this source contamination environment, while generating valuable biomass. Additionally, strategy employed, requires minimal control culture simplifying integration these systems real-world facilities improved management.

Acclimated green microalgae consortium to treat sewage in an alternative urban WWTP in a coastal area of Central Italy

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 945, P. 174056 - 174056

Published: June 18, 2024

This study exposed a microalgal consortium formed by Auxenochlorella protothecoides, Tetradesmus obliquus, and Chlamydomonas reinhardtii to six mixed wastewater media containing different proportions of primary (P) or secondary (S) effluents diluted in centrate (C). Algae could grow at concentrations up 50 %, showing no significant differences between effluents. After acclimation, microalgae cultivated 50%P-50%C 50%S-50%C grew rate similar that control cultures (0.59–0.66 d−1). These results suggest the acclimated both sewage streams modulating proportion species their metabolism. Acclimation also altered photosynthetic activity wastewater-grown samples compared control, probably due partial photoinhibition, changes composition, metabolic activity. No major were observed two with respect biochemical biomass yield, bioremediation capacity algae but grown effluent showed qualitatively higher exopolysaccharides (EPS) production than primary. Regarding remediation, WW proficient nutrient removal efficiencies (close 100 %); however, final pH value 11) would be controversial if system upscaled as it is over legal limit cause phosphorus precipitation, so CO2 addition required. The theoretical scale-up achieve water treatment costs 0.109 €·m−3, which was significantly lower typical activated sludge systems.

Transforming recalcitrant wastes into biodiesel by oleaginous yeast: An insight into the metabolic pathways and multi-omics landscape

Chemical Engineering Journal, Journal Year: 2023, Volume and Issue: 474, P. 145625 - 145625

Published: Aug. 26, 2023

The escalating challenge of waste disposal and the potential threat to global energy supply have sparked renewed interest in repurposing materials for production sustainable renewable fuels. In line with this objective, there has been a growing focus on biodiesel from oleaginous yeast through valorization waste. While numerous reports published subject, only limited number studies provide comprehensive overview recent advancements. To address gap economic viability challenges associated yeast-derived production, present review aims highlight opportunities offered by various recalcitrant wastes as feedstock cultivation. also delves into extensive knowledge about metabolic pathways that facilitate conversion different single-cell oil (SCO), which not extensively covered single platform before. Moreover, most promising species are described, taking consideration aspects sustainability overall process. Furthermore, emphasizes application omics techniques advance bioconversion lipids purpose commercialization. summary, study contributes expanding our current understanding topic facilitates future upscaling commercialization derived yeasts.
