“…Co-cultivation of Scenedesmus sp., and Chlorella sorokiniana in BWW, showed that 78% organic pollutant removal with 90–97% removal of ammonia, total nitrogen, and phosphorous. Produced biomass recovered 16 mg/l of chlorophyll, 9.57 mg/L of carotenoids, and 30.4 mg/L of carbohydrates respectively (Han et al 2021 ). Song et al ( 2020 ) reported that the cultivation of Chlorella sp.,Spirulina , and Scenedesmus sp., in the BWW prove that Scenedesmus sp ., are fast-growing and adapted organisms in BWW with 1.02 g/L of biomass production with nutrients removal of COD (73%), ammonia (89%), total nitrogen (75%), and phosphorous (95%), respectively.…”

Microalgae are recognized as cell factories enriched with biochemicals suitable as feedstock for bio-energy, food, feed, pharmaceuticals, and nutraceuticals applications. The industrial application of microalgae is challenging due to hurdles associated with mass cultivation and biomass recovery. The scale-up production of microalgal biomass in freshwater is not a sustainable solution due to the projected increase of freshwater demands in the coming years. Microalgae cultivation in wastewater is encouraged in recent years for sustainable bioeconomy from biorefinery processes. Wastewater from the food industry is a less-toxic growth medium for microalgal biomass production. Traditional wastewater treatment and management processes are expensive; hence it is highly relevant to use low-cost wastewater treatment processes with revenue generation through different products. Microalgae are accepted as potential biocatalysts for the bioremediation of wastewater. Microalgae based purification of wastewater technology could be a universal alternative solution for the recovery of resources from wastewater for low-cost biomass feedstock for industry. This review highlights the importance of microalgal biomass production in food processing wastewater, their characteristics, and different microalgal cultivation methods, followed by nutrient absorption mechanisms. Towards the end of the review, different microalgae biomass harvesting processes with biorefinery products, and void gaps that tend to hinder the biomass production with future perspectives will be intended. Thus, the review could claim to be valuable for sustainable microalgae biomass production for eco-friendly bioproduct conversions. Graphical abstract

In light of global concerns regarding greenhouse gas emissions, a CO 2 absorption and microalgae conversion (CAMC) system has been proposed as a potential solution. This study investigated the impact of a mixed absorbent containing trans-1,4diaminocyclohexane (DACH) and K 2 CO 3 on Chlorella L166's growth and the CAMC system and explored the regulatory mechanism. Results showed that a 1:50 mixture of DACH and K 2 CO 3 increased the dissolved inorganic carbon content, enabling better growth and better fixation of CO 2 by Chlorella L166. The chlorophyll a, carotenoid, and carbohydrate contents were 11.89, 16.67, and 31.28% higher than those of the control group (0:50), respectively. Transcriptome analysis suggested that the mixed absorbent altered gene expression in microalgal cells and influenced their cellular composition. Upregulation of processes such as photosynthesis, the Calvin cycle, and carbohydrate metabolism facilitated the redirection of more energy toward carbon fixation and carbohydrate accumulation, thereby improving the growth performance of Chlorella L166. Overall, the mixed absorbent is an effective strategy to enhance the performance of the CAMC system.

“…Co-cultivation of microalgae species offers exciting prospects for environmental pollutant removal and renewable energy production. The mutualistic interactions among microalgae enhance nutrient removal capacity and facilitate adaptation to varying environmental conditions in the wastewater treatment system ( Han et al, 2021 ). For instance, Prathima Devi et al achieved a biomass concentration of 0.98 mg.L -1 .…”

The burgeoning human population has resulted in an augmented demand for raw materials and energy sources, which in turn has led to a deleterious environmental impact marked by elevated greenhouse gas (GHG) emissions, acidification of water bodies, and escalating global temperatures. Therefore, it is imperative that modern society develop sustainable technologies to avert future environmental degradation and generate alternative bioproduct-producing technologies. A promising approach to tackling this challenge involves utilizing natural microbial consortia or designing synthetic communities of microorganisms as a foundation to develop diverse and sustainable applications for bioproduct production, wastewater treatment, GHG emission reduction, energy crisis alleviation, and soil fertility enhancement. Microalgae, which are photosynthetic microorganisms that inhabit aquatic environments and exhibit a high capacity for CO2 fixation, are particularly appealing in this context. They can convert light energy and atmospheric CO2 or industrial flue gases into valuable biomass and organic chemicals, thereby contributing to GHG emission reduction. To date, most microalgae cultivation studies have focused on monoculture systems. However, maintaining a microalgae monoculture system can be challenging due to contamination by other microorganisms (e.g., yeasts, fungi, bacteria, and other microalgae species), which can lead to low productivity, culture collapse, and low-quality biomass. Co-culture systems, which produce robust microorganism consortia or communities, present a compelling strategy for addressing contamination problems. In recent years, research and development of innovative co-cultivation techniques have substantially increased. Nevertheless, many microalgae co-culturing technologies remain in the developmental phase and have yet to be scaled and commercialized. Accordingly, this review presents a thorough literature review of research conducted in the last few decades, exploring the advantages and disadvantages of microalgae co-cultivation systems that involve microalgae-bacteria, microalgae-fungi, and microalgae-microalgae/algae systems. The manuscript also addresses diverse uses of co-culture systems, and growing methods, and includes one of the most exciting research areas in co-culturing systems, which are omic studies that elucidate different interaction mechanisms among microbial communities. Finally, the manuscript discusses the economic viability, future challenges, and prospects of microalgal co-cultivation methods.
