“…Algae can uptake nutrients through ion exchange and adsorption processes, whereby ions are exchanged between the algal cell surface and the surrounding water or adsorbed onto cell surfaces. This mechanism allows algae to efficiently capture dissolved nutrients from the wastewater matrix, facilitating nutrient removal from the aqueous phase (Narvarte, et. al., 2023, Sanz-Luque, Bhaya & Grossman, 2020, Zafar, et.…”

Algae-based wastewater treatment systems have gained significant attention as sustainable and efficient solutions for nutrient removal, organic pollutant degradation, and biomass production. This comprehensive review explores the role of algae-based systems in wastewater treatment, covering key aspects such as nutrient uptake mechanisms, cultivation techniques, system design considerations, and environmental sustainability implications. Algae offer unique advantages for wastewater treatment, including high nutrient removal rates, CO2 sequestration, and the production of valuable biomass for biofuel production and nutrient recycling. Various cultivation methods, including open ponds, raceways, photobioreactors, and wastewater treatment wetlands, are evaluated for their suitability in different wastewater treatment scenarios. The integration of algae-based systems with conventional wastewater treatment processes, such as activated sludge and membrane bioreactors, is discussed to enhance treatment efficiency and resource recovery. Furthermore, the environmental sustainability of algae-based systems, including carbon footprint, water footprint, and ecosystem impacts, is assessed to identify opportunities for mitigating environmental impacts and promoting ecosystem resilience. Future research directions in algae-based wastewater treatment systems, such as optimization of cultivation conditions, development of novel algal strains, and techno-economic analysis of large-scale implementation, are proposed to address remaining challenges and accelerate the adoption of algae-based technologies in wastewater treatment practices. Overall, this review provides valuable insights into the role of algae-based systems as sustainable and versatile tools for wastewater treatment, highlighting their potential to address the growing challenges of nutrient pollution and water scarcity in the 21st century.

“…Observation showed phosphate and nitrate levels ranged from 0.1-0.46 mg/L to 0.2-0.5 mg/L, respectively; this value is higher than the quality standard. According to Narvarte et al (2023), phosphate levels in moderately fertile waters range between 0.0021-0.05 mg/L, and fertile waters range between 0.051-0.1 mg/L. There is a suspicion that the elevated phosphate and nitrate levels in the waterways north of Banda Aceh are largely influenced by land-based sources, such as domestic trash.…”

Abstract. Akbar SA, Hasan M, Afriani S, Nuzlia C. 2023. Evaluation of phytochemical composition and metabolite profiling of macroalgae Caulerpa taxifolia and C. peltata from the Banda Aceh coast, Indonesia. Biodiversitas 24: 5283-5292. The study of seaweeds to extract their bioactive compounds has become increasingly important from the standpoint of broader applications. This study aimed to examine the metabolite profiles and phytochemical content of Caulerpa peltata and Caulerpa taxifolia along the coast of Banda Aceh in Indonesia. Readers interested in learning more about the biological activities of C. peltata and C. taxifolia can refer to the material gathered from this study. The three steps proposed by this study were phytochemical composition, antioxidant scavenging, and in vivo metabolite profiling by the use of Gas Chromatography-Mass Spectrometry (GC-MS), Fourier Transform Infrared (FTIR) characterization, and the 2,2-diphenylpicrylhydrazyl (DPPH) test. Using DPPH to measure antioxidant activity, both extracts demonstrated greater scavenging capability, with inhibition values of 42.59% and 39.81%, respectively. In both macroalgae, the GC-MS methodology has shown to be a quick, sensitive, and trustworthy way to monitor individual components and the entire chemical composition. In C. taxifolia, there are 29 phytochemical compounds, whereas in C. peltata, there are 26 types. The ethanol extract of the macroalgae C. taxifolia and C. peltata was then subjected to an FTIR spectrum. These findings at 3352 cm-1, 1654 cm-1, and 1019 cm-1 proved that alkanes, alkenes, and hydroxyl groups were present, corresponding to several compounds in the GC-MS measurement results. Caulerpa taxifolia and C. peltata are potential antibacterial agents; the bioactive compounds for this activity are Heptadecane, Hexadecanoic acid, and other ester derivatives.

“…Studies have demonstrated that algal cells can store nitrate-nitrogen in vesicles following uptake. The intracellular and extracellular nitrate-nitrogen concentration ratio can reach 1000:1 (Narvarte et al, 2023), which ensures an ample supply of nitrogen required for other physiological processes such as photosynthesis and carbon fixation in algal cells. Xu and Gao (2012) have reported in Gracilaria lemaneiformis that high levels of UVR can disrupt the molecular structure of NR and reduce its activity.…”
