Synechocystis sp. PCC 6803, a cyanobacterium widely used for basic research, is often cultivated in a synthetic medium, BG-11, in the presence of 4-(2hydroxyethyl)-1-piperazine ethanesulfonic acid (HEPES) or 2-[[1,3-dihydroxy-2-(hydroxymethyl)propan-2-yl]amino]ethanesulfonic acid buffer. Owing to the high cost of HEPES buffer (96.9% of the total cost of BG-11 medium), the biotechnological application of BG-11 is limited. In this study, we cultured Synechocystis sp. PCC 6803 cells in BG-11 medium without HEPES buffer and examined the effects on the primary metabolism. Synechocystis sp. PCC 6803 cells could grow in BG-11 medium without HEPES buffer after adjusting for nitrogen sources and light intensity; the production rate reached 0.54 g cell dry weight/L/day, exceeding that of commercial cyanobacteria and Synechocystis sp. PCC 6803 cells cultivated under other conditions. The exclusion of HEPES buffer markedly altered the metabolites in the central carbon metabolism; particularly, the levels of compatible solutes, such as sucrose, glucosylglycerol, and glutamate were increased. Although the accumulation of sucrose and glucosylglycerol under high salt conditions is antagonistic to each other, these metabolites accumulated simultaneously in cells grown in the cost-effective medium. Because these metabolites are used in industrial feedstocks, our results reveal the importance of medium composition for the production of metabolites using cyanobacteria.

“…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 ). A review study by Pancha et al (2019) showed various microalgae lipid content cultivated in various wastewaters ranging from 18–79% w/w of biomass.…”

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.

“…Moreover, analysis of fatty acid methyl esters (FAME) indicated that the predominant fatty acids, including palmitic acid (C16:0), linoleic acid (C18:2 n6 cis), palmitoleic acid (C16:1), and oleic acid (C18:1 n9 cis), constituted over 80% of total fatty acids. This composition highlights the strain's potential for simultaneous water treatment and biomass production for biofuel feedstock (Srimongkol et al, 2019b). A review by Pancha et al (2019) demonstrated that various microalgae cultivated in different wastewaters had lipid contents ranging from 18% to 79% w/w of biomass.…”

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.
