“…Ultrasonic power and processing time are two important parameters for extracting high-value products from microorganisms, including microalgae. (Zheng et al, 2021). Kuhavichanan et al (2018) reported that increasing the processing time of sonication treatment resulted in higher protein yields for green microalga Coelastrum sp.…”

Disruption methods used to extract proteins from the cell often require optimization in terms of yield increase and molecular integrity according to the cell type. Most cell lysis methods primarily target the cell wall. However, even for the wall-deficient strains, efficient extraction of molecules in or attached to membranous structures is a delicate process. In this study, we optimized the protein extraction technique for a cell wall deficient strain of Chlamydomonas reinhardtii, which is also a preferred material for most of the recombinant protein production studies. Liquid nitrogen (LN) was evaluated for efficient protein extraction from wall-less strain. The results were compared with sonic treatments, which were optimized in terms of applied power and duration. The results showed that sonication at 25% power for 20 seconds of three rounds provided optimum results for the protein integrity and extraction yield (74.13±2 µg/mL and 185.32±5 mg/g). Although LN has provided similar results in terms of protein content compared to sonication, (70.15±4.43 µg/mL and 175.37±11.09 mg/g maximum), it revealed low efficiency in extracting intact proteins from sub-compartments of the cell.

“…It has significant carbon recovery capabilities and helps to achieve a higher carbon neutrality percentage (Chew & Show, 2022). Microalgae‐based water treatment can potentially improve biomass recovery, which can generate high‐value‐added products, in contrast to other traditional water treatment techniques (Zheng et.al 2021). Microalgae can survive in a variety of environments and use sunlight to break down harmful chemicals into usable biomass (Oliveira et.al 2021). Microalgal cultivation can be achieved using highly concentrated water, as the algal phylum contains extremophiles well‐adapted to harsh conditions (Vishwakarma et.al 2022).…”

Post technological advancements and industrialisation, the recovery of resources by treating wastewater is gaining momentum. As the global population continues to grow, the need for water is becoming increasingly urgent. Therefore, the re‐utilisation of water is becoming an increasingly important factor in the preservation of life on this planet. Wastewater is classified according to its source of origin. When left untreated, the effluent causes several environmental hazards and poses health issues as they have higher concentrations of nutrients and toxic heavy metals. Currently, several conventional methods exist to treat and handle wastewater, but they generate secondary waste post‐treatment and are not sustainable. Microalgae‐based treatment of wastewater is highly sustainable, cost‐efficient and aligns with the concept of circular bioeconomy. The biological treatment of effluents using microalgae has several advantages. Approximately 1.83 kg of CO2 is sequestered per kg of the dry biomass during microalgae cultivation. Among all the sustainable alternatives, microalgae offer better biomass productivity by utilising a higher concentration of nutrients in wastewater. The wastewater‐grown microalgae have higher efficiency in producing commercially important secondary metabolites. This systematic review highlights the competence of microalgae in different wastewater sources and their industrial perspectives. This also gives an overview of the biproducts produced from microalgae‐based wastewater treatment.

“…These pressure fluctuations create a large number of cavitation bubbles, which undergo stretching and compression due to the continuous waves. Eventually, the bubbles implode, releasing a significant amount of energy into the liquid, resulting in the formation of shock waves, high temperature, and shear forces that rupture microalgae cells [55,56]. Ultrasound power, frequency, amplitude, time, temperature, solvent type, and exposure mode are the primary factors that are crucial to the ultrasound process.…”

Microalgae have emerged as a promising source of renewable energy and natural bioproducts since they show high biomass productivity, offer carbon dioxide fixation, and exhibit a rich content of compounds. Recent efforts have focused on green extraction technologies that utilize green solvents to further promote sustainability and minimize the environmental impact of the microalgal process. At this point, life cycle analysis (LCA) provides valuable insights into the environmental impacts of specific products and techniques. A comprehensive overview of the life cycle environmental and energy assessments conducted for the extraction of metabolites from microalgae is presented. Special attention is given to using green extraction technologies, i.e., supercritical fluid extraction, pressurized liquid extraction, microwave‐assisted extraction, ultrasound‐assisted extraction, and pulsed‐electric field extraction, and solvents to ensure sustainability. Additionally, the main principles, historical development, tools, and challenges of LCA are discussed. By addressing these aspects, the paper attracts attention to the environmental impacts associated with green extraction techniques for obtaining microalgal metabolites.
