“…They are an essential component of the membrane and light-harvesting complex, which contains a large number of catalytic enzymes that are involved in the photosynthesis process. In terms of quantity, several species of microalgae have been reported to contain extremely high concentrations of protein; on a dry weight basis, these concentrations can range from 42% to over 70% in certain cyanobacteria and up to 58% in C. vulgaris , according to the literature ( Hachicha et al, 2022 ). Microalgae are high in nutritional value because they contain all of the essential amino acids that mammals are unable to produce.…”

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.

“…The main challenges appear to be the high cost of operation, infrastructure, maintenance, mass production, bioproduct accumulation and extraction [ 138 ]. Using industrial or agricultural waste contained with less microbial load should be adapted to a medium for sustainability and thus saving costs for the industrial scale.…”

Recently, microalgal biotechnology has received increasing interests in producing valuable, sustainable and environmentally friendly bioproducts. The development of economically viable production processes entails resolving certain limitations of microalgal biotechnology, and fast evolving genetic engineering technologies have emerged as new tools to overcome these limitations. This review provides a synopsis of recent progress, current trends and emerging approaches of genetic engineering of microalgae for commercial applications, including production of pharmaceutical protein, lipid, carotenoids and biohydrogen, etc. Photochemistry improvement in microalgae and CO2 sequestration by microalgae via genetic engineering were also discussed since these subjects are closely entangled with commercial production of the above mentioned products. Although genetic engineering of microalgae is proved to be very effective in boosting performance of production in laboratory conditions, only limited success was achieved to be applicable to industry so far. With genetic engineering technologies advancing rapidly and intensive investigations going on, more bioproducts are expected to be produced by genetically modified microalgae and even much more to be prospected.

“…The microalga biomass is used for various purposes, but for their overproduction there are various challenges such as high-cost maintenance, feedback inhibition, and low space availability for pigment droplets accumulation, and its extraction [73]. High production cost is due to low biomass productivity and poorly developed bio-refinery technologies [44,74].…”

Globally, microalgae are gaining attention due to their high nutritional value and broad application in the pharmaceutical, nutraceutical, food, cosmetics, bio-fertilizer, and biofuel industries. Microalgal-based foods have been shown a positive impact on human health by acting as antioxidants, antimicrobials, anti-inflammatory agents, and antiviral agents. Scale-up, production cost, and safety issues are the significant challenges in microalgae product commercialization. However, various techniques have been developed to overcome these challenges and to produce microalgae bio-products in a high amount and make them safe for human and animals use. Recently, multiple techniques such as metabolic and genetic engineering have emerged to overcome these limitations. The present review focused on the application of these engineering tools to improve biomass yield and nutrient quality in microalgae. However, these tools are proved to be very effective in enhancing the nutrients in microalgae. Limited success has been achieved to improve the quality at the industrial level.
