“…The MUFA content of the lipids in the biomass obtained with the mixed culture (6.9%) was higher than that obtained with the microalgae monoculture (4%). The latter finding is consistent with the results reported in another study, where lipids produced by the binary mixtures of CV/Rhodopseudomonas palustris (21.1%), CV/Rhodobacter sphaeroides (24.5%) and Chlorella pyrenoidosa/ Rhodobacter sphaeroides (29.3%) had a higher oleic acid content than those of the microalgae monocultures [41].…”

Microalgae-based renewable energy, industrial chemicals, and food have received great attention during the last decade. This review article highlights the versatility of algal biomass as a feedstock for producing various commodities and high-value products, including aromatic hydrocarbons and lipids within biorefinery systems. Lipid content and the composition of algal biomass cultivated in various media, specifically in wastewater streams generated at agricultural and industrial production facilities, are reviewed. Technical and chemical aspects of algal biomass conversion via thermochemical techniques including pyrolysis, hydrothermal liquefaction, and hydrothermal carbonization are discussed. The properties of the final products are reviewed based on the conversion process employed. Studies published within the last 5 years are reviewed. The importance of further research on inexpensive and more effective catalysts and the development of downstream processes to upgrade crude products obtained from thermal conversion processes is emphasized. This review concludes with an in-depth discussion of the opportunities and challenges involved in algal biomass-based bioproduct manufacturing and commercialization.

“…Nonetheless, it is important to note that these studies are still in their early experimental phases but the prospects are promising. On the other hand, a broader spectrum of co-cultures involving photosynthetic organisms has been directed towards wastewater treatment, with a particular emphasis on augmenting the sequestration of specific chemicals or assisting in the growth of biomass to enhance nutrient removal [62,63]. In addition to chemical removal, certain co-cultures, particularly those involving algae and fungus, demonstrated the ability to form aggregated structures that facilitated easier settling and removal from wastewater, streamlining the wastewater treatment process [64].…”

Meso- and extremophilic microalgae and cyanobacteria have a wide range of biotechnological applications. However, the industrial demand for bioactive molecules and the redundancy of these molecules has resulted in a need for new methodologies for enhanced production and the discovery of specialized metabolites. Co-cultivation has been established as a promising approach to addressing these challenges. In this context, this work aimed to describe the state of the art of the co-cultivation method involving meso- and extremophilic photosynthetic microorganisms, as well as discuss the advantages, challenges, and limitations of this approach. Co-culture is defined as an ecology-driven method in which various symbiotic interactions involving cyanobacteria and microalgae can be used to explore new compounds and enhanced production. Promising results regarding new bioactive metabolite expression and increased production through co-cultivation-based research support that idea. Also, the metabolic diversity and evolutionary adaptations of photosynthetic microorganisms to thrive in extreme environments could improve the efficiency of co-cultivation by allowing the implementation of these microorganisms. However, the complexity of ecological interactions and lack of standardization for co-cultivation protocols are obstacles to its success and scientific validation. Further research in symbiotic interplays using -omics and genetic engineering, and predictive experimental designs for co-cultures are needed to overcome these limitations.
