“…Methylotrophic or methylautotrophic microbes-or model organisms created for methanol-based heterotrophic fermentation -have been suggested as ideal bacteria to supplement delivered food [57]. Microalgae cultivation has numerous advantages over plant crops [65]. They can be cultivated in straightforward stirred reactors using readily available raw materials like atmospheric CO2 and redox couples found in the regolith or methanol produced by the catalytic reduction of CO2.…”

As humanity sets its sights on establishing a sustainable and prosperous colony on Mars, the main challenges to be overcome are ensuring a reliable and nutritious food supply for settlers, feedstock for 3D printing, fuel and pharmaceuticals. While various solutions for production of essential products on Mars have been proposed, there is growing interest in the use of microorganisms as the main production units. This scientific review article proposes a novel concept of using single cell oil (SCO) as a versatile feedstock for various applications in a bioregenerative life support system (BLSS) for space missions. The authors suggest using outputs from autotrophic systems, such as cyanobacteria biomass and oxygen, to cultivate SCO-producing microorganisms from the class Labyrinthulomycetes. The produced SCO can be used for food, fuel, 3D printing materials, and pharmaceuticals. This approach can potentially reduce the importance of carbohydrates in space foods, offering various benefits, including a reduction in food weight, simpler, lightweight, more compact bioreactors, launch cost reduction, potentially improved mental and cognitive performance, and reduced fatigue for the crew. The authors also suggest using SCO as the feedstock for the production of 3D printable filaments and resins and as a supplementary fuel source for space colonies. While the concept is hypothetical, the theoretical foundation is solid, and this approach could potentially become an important element required for the establishment of a successful Mars colony.

“…In recent years, it has been proven that microalgae produce significant metabolites which show unique biological activities such as antibacterial, antiviral, antifungal, non-cytotoxic, immunosuppressive effects [21][22][23][24][25][26] . The increasing concerns about the infection rates of antibiotic-resistant microorganisms have caused to great attention on investigating the antimicrobial activities of microalgae [27,28,37,38,[29][30][31][32][33][34][35][36] . As a result of the researches, it has been proven that the presence of antibacterial compounds to be derived from microalgae biomass is highly dependent on the solvent used to extract these compounds, as well as the microalgae species.…”

Background: Sutures act as excellent surfaces that allow bacteria to penetrate wounds. In this way, they cause microbial colonization, biofilm formation, and thus surgical sites infection. Such side effects have a great impact on the human life quality. Therefore, the concerns about this issue are increasing rapidly. At this point, microalgae have been drawn attention with their high-biologically active compounds. In this study, A. platensis, H. pluvialis, C. minutissima, B. braunii and N. muscorum extracts were investigated for their usability potential as surgical suture covering material. Methods: In order to evaluate their biocompatibility, the antibacterial activities and cytotoxic effects of the sutures [PGLA and PDO] coated with these extracts were determined. Major results: The results showed that A. platensis and N. muscorum extracts have acceptable cytotoxic levels on L929 cell line according to ISO 10993-5. Moreover, A. platensis extract was found to be the most promising suture coating material for the human applications. Conclusions: The surgical sutures have been successfully coated with extracts derived from microalgae species. As a result, it has been proven that antibacterial sutures could be obtained, and the biological properties of surgical sutures could be improved by using microalgal antibacterial extracts. In summarize, it appears as microalgal extracts can used in biological materials with potential application in the pharmaceutical industries due to its ingredients.
