“…Researchers have estimated the following facts: Chroococcidiopsis can grow for 60 days, accumulate biomass of 16.08 g/m 2 /d. The biomass is rich in phycobiliproteins and essential fatty acids, as such it is suitable for animal food, not toxic to fish, and most importantlythe produced biomass has the quality to settle spontaneously, which eliminates the need of expensive centrifugation or separation techniques (14). We can consider the result optimistic, especially concerning the lack of toxicity to fish.…”

Recently some researchers have gathered around the claim that the likelihood for terraformation of Mars is slim, either because human technology is not up to the task, or the planet does not posses all the necessary resources to allow the process to be completed successfully. This manuscript takes a closer look both at the latest and previous scientific articles, optimistic and skeptical, while trying to reassess the terraforming potential of the planet. To achieve that, we summarized results from different experiments conducted with algae and higher plants. According to our reevaluation, it is concluded that even if the skeptical papers are right, and the others are overly optimistic, partial terraformation of Mars is still possible. It is also suggested that terraforming the planet partially could be a good option if we want to protect the local organisms, assuming that they exist.

“…Several filamentous cyanobacteria form a tangled mesh that can settle to the bottom or float to the top, making biomass separation relatively easier [212]. Some other microalgae and cyanobacteria produce exopolysaccharides, which assist in forming flocs of the cells; these flocs can settle spontaneously to the bottom [213]. Non-settling microalgal cells can also be harvested by taking advantage of sedimentation exhibiting microalgal or yeast strains-a process known as bio-flocculation [214].…”

Whole-cell microalgae biomass and their specific metabolites are excellent sources of renewable and alternative feedstock for various products. In most cases, the content and quality of whole-cell biomass or specific microalgal metabolites could be produced by both fresh and marine microalgae strains. However, a large water footprint for freshwater microalgae strain is a big concern, especially if the biomass is intended for non-food applications. Therefore, if any marine microalgae could produce biomass of desired quality, it would have a competitive edge over freshwater microalgae. Apart from biofuels, recently, microalgal biomass has gained considerable attention as food ingredients for both humans and animals and feedstock for different bulk chemicals. In this regard, several technologies are being developed to utilize marine microalgae in the production of food, feed, and biofuels. Nevertheless, the production of suitable and cheap biomass feedstock using marine microalgae has faced several challenges associated with cultivation and downstream processing. This review will explore the potential pathways, associated challenges, and future directions of developing marine microalgae biomass-based food, feed, and fuels (3F).

Biological-Based Produced Water Treatment Using Microalgae: Challenges and Efficiency

et al. 2022

View full text Add to dashboard Cite

Produced water (PW) is the most significant waste stream generated in the oil and gas industries. The generated PW has the potential to be a useful water source rather than waste. While a variety of technologies can be used for the treatment of PW for reuse, biological-based technologies are an effective and sustainable remediation method. Specifically, microalgae, which are a cost-effective and sustainable process that use nutrients to eliminate organic pollutants from PW during the bioremediation process. In these treatment processes, microalgae grow in PW free of charge, eliminate pollutants, and generate clean water that can be recycled and reused. This helps to reduce CO2 levels in the atmosphere while simultaneously producing biofuels, other useful chemicals, and added-value products. As such, this review focuses on PW generation in the oil and gas industry, PW characteristics, and examines the available technologies that can be used for PW remediation, with specific attention to algal-based technologies. In addition, the various aspects of algae growth and cultivation in PW, the effect of growth conditions, water quality parameters, and the corresponding treatment performance are presented. Lastly, this review emphasizes the bioremediation of PW using algae and highlights how to harvest algae that can be processed to generate biofuels for added-value products as a sustainable approach.
