“…In a preliminary study of biomass production and ammonium removal in Synechococcus sp. VDW (accession number MH393765) isolated from natural seawater in Thailand ( Tinpranee et al, 2018 ), we discovered that at optimum conditions (initial pH 7.4, inoculum size of 0.17 (OD 730 ), and ammonium concentration of 10.5 mg L −1 ), maximum ammonium removal and biomass productivity were 95% and 34 mg L −1d−1 , respectively. Furthermore, fatty acid methyl ester (FAME) analysis revealed that the major fatty acids were palmitic acid (C16:0), linoleic acid (C18:2 n6 cis), palmitoleic acid (C16:1), and oleic acid (C18:1 n9 cis), accounting for more than 80% of total fatty acids, indicating that this strain has potential for simultaneous water treatment and biomass production for biofuel feedstock ( Srimongkol et al, 2019b ).…”

Over the last several decades, concerns about climate change and pollution due to human activity has gained widespread attention. Microalgae have been proposed as a suitable biological platform to reduce carbon dioxide, a major greenhouse gas, while also creating commercial sources of high-value compounds such as medicines, cosmetics, food, feed, and biofuel. Industrialization of microalgae culture and valorization is still limited by significant challenges in scaling up the production processes due to economic constraints and productivity capacities. Therefore, a boost in resource usage efficiency is required. This enhancement not only lowers manufacturing costs but also enhancing the long-term viability of microalgae-based products. Using wastewater as a nutrient source is a great way to reduce manufacturing costs. Furthermore, water scarcity is one of the most important global challenges. In recent decades, industrialization, globalization, and population growth have all impacted freshwater resources. Moreover, high amounts of organic and inorganic toxins in the water due to the disposal of waste into rivers can have severe impacts on human and animal health. Microalgae cultures are a sustainable solution to tertiary and quaternary treatments since they have the ability to digest complex contaminants. This review presents biorefineries based on microalgae from all angles, including the potential for environmental pollution remediation as well as applications for bioenergy and value-added biomolecule production. An overview of current information about microalgae-based technology and a discussion of the associated hazards and opportunities for the bioeconomy are highlighted.

Microalgae, as photosynthetic microorganisms, possess significant potential in addressing environmental challenges and promoting sustainable practices. This review explores the wide-ranging applications of microalgae, emphasizing their pivotal roles in bioremediation, biofuel production, bioethanol generation, and biofertilizer development. Microalgae’s ability to thrive in various wastewater types, including municipal, agricultural, and industrial, signifies a sustainable approach to wastewater treatment. By efficiently removing nitrogen, phosphorus, carbon, and heavy metals, microalgae make substantial contributions to environmental sustainability. Furthermore, their integration into wastewater treatment processes not only reduces operational costs but also yields valuable biomass for various applications. Microalgae’s capacity to sequester carbon dioxide, coupled with their role in enhancing soil fertility, renders them invaluable tools in mitigating climate change and promoting sustainable agriculture. This review underscores the importance of ongoing research to fully harness microalgae’s potential, paving the way for a greener and more resilient future. It summarizes the effects of microalgae’s potential on agricultural soil and wastewater treatments, among other areas, by examining relevant works related to the topic. To achieve this, databases such as Google Scholar, Frontier in Microbiology, Microbial Cell Factory (MCF), Scopus, Web of Science, ScienceDirect, and Directory of Open Access Journals (DOAJ) were explored to identify studies on microalgae’s potential in various fields.

“…Wild-type Synechococcus sp. VDW (GenBank database accession number MH393765), collected from Ao Wong Duan, Koh Samet, Thailand in July 2012 ( 9 ), was selected as the representative microalgal strain in this study. The cultures were grown in BG11 broth combined with Turks Island salt solution (pH=7.5; Merck, Kenilworth, NJ, USA) for maintenance and cell production ( 10 ) and were incubated at 30 °C in 250-mL flasks under daylight fluorescent tubes with light intensity of 30 µmol/(m 2 ·s).…”

SUMMARYThis study aims to determine the antioxidant activity of bioactive peptides derived from Synechococcus sp. VDW cells cultured for 21 days. Synechococcus sp. VDW protein hydrolysates were prepared with trypsin and purified by ultrafiltration with molecular mass cut-off membranes of 10, 5 and 3 kDa. The M<3 kDa (FA) fraction had the highest 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) and 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities, with IC50 values of (11.5±0.3) and (13.6±0.2) µg/mL, respectively. The FA fraction was separated by reversed phase HPLC to yield four subfractions (F1–4). The F4 subfraction showed the highest maximum ABTS radical scavenging activity (3.55±0.61) % and it was selected for further analysis by electrospray ionisation quadrupole time-of-flight mass spectrometry (ESI-Q-TOF-MS/MS) based on de novo peptide sequencing. Five antioxidant peptides were identified, of which AILESYSAGKTK had the highest ABTS radical scavenging activity. Furthermore, the FA fraction showed high cytotoxic activities against human cancer-derived cell lines, especially the colon cancer cell line (SW620) with an IC50 value of (106.6±21.5) µg/mL, but not the untransformed Wi38 cell line. The FA fraction activated the apoptotic pathway in SW620 cells after treatment for 24, 48 and 72 h, with the highest activities of caspases-3, -8 and -9 being observed after treatment for 72 h. These findings suggested that microalgae Synechococcus sp. VDW may be used to develop natural anticancer drugs.
