Astaxanthin as a King of Ketocarotenoids: Structure, Synthesis, Accumulation, Bioavailability and Antioxidant Properties

Marine Drugs, Год журнала: 2023, Номер 21(3), С. 176 - 176

Опубликована: Март 13, 2023

Astaxanthin (3,3-dihydroxy-β, β-carotene-4,4-dione) is a ketocarotenoid synthesized by Haematococcus pluvialis/lacustris, Chromochloris zofingiensis, Chlorococcum, Bracteacoccus aggregatus, Coelastrella rubescence, Phaffia rhodozyma, some bacteria (Paracoccus carotinifaciens), yeasts, and lobsters, among others However, it majorly lacustris alone (about 4%). The richness of natural astaxanthin over synthetic has drawn the attention industrialists to cultivate extract via two stage cultivation process. in photobioreactors expensive, converting soluble form so that can be easily assimilated our digestive system requires downstream processing techniques which are not cost-effective. This made cost prompting pharmaceutical nutraceutical companies switch astaxanthin. review discusses chemical character astaxanthin, more inexpensive cultivating techniques, its bioavailability. Additionally, antioxidant this microalgal product against many diseases discussed, make compound an excellent drug minimize inflammation consequences.

Cultivation of microalgae–bacteria consortium by waste gas–waste water to achieve CO2 fixation, wastewater purification and bioproducts production

Biotechnology for Biofuels and Bioproducts, Год журнала: 2024, Номер 17(1)

Опубликована: Фев. 15, 2024

Abstract The cultivation of microalgae and microalgae–bacteria consortia provide a potential efficient strategy to fix CO 2 from waste gas, treat wastewater produce value-added products subsequently. This paper reviews recent developments in fixation treatment by single microalgae, mixed consortia, as well compares summarizes the differences utilizing different microorganisms aspects. Compared monoculture consortium may mitigate environmental risk, obtain high biomass, improve efficiency nutrient removal. applied include Chlorella sp., Scenedesmus Pediastrum Phormidium sp. among others, most strains belong Chlorophyta Cyanophyta. bacteria are mainly activated sludge specific sewage sources. Bioengineer CBB cycle cells effective achieve improvement or yield high-value products. mechanisms removal microbial systems also explored concluded, importance technology is proven. After cultivation, biomass can be harvested through physical, chemical, biological magnetic separation methods used by-products, such biofuel, feed, food, biochar, fertilizer, pharmaceutical bio-compounds. Although this has brought many benefits, some challenging obstacles limitation remain for industrialization commercializing. Graphical

Unlocking the Therapeutic Potential of Algae-Derived Compounds in Hematological Malignancies

Cancers, Год журнала: 2025, Номер 17(2), С. 318 - 318

Опубликована: Янв. 20, 2025

Algae are a rich source of bioactive compounds that have wide range beneficial effects on human health and can show significant potential in the treatment hematological malignancies such as leukemia, lymphoma, multiple myeloma. These diseases often pose therapeutic challenge despite recent advances (e.g., use immunomodulatory drugs, proteasome inhibitors, CD38 monoclonal antibodies, stem cell transplant, targeted therapy). A considerable number patients experience relapses or resistance to applied therapies. Algal compounds, alone combination with chemotherapy other more advanced therapies, exhibited antitumor preclinical studies may improve disease outcomes. include ability induce apoptosis, inhibit tumor growth, immune responses. However, most these conducted vitro, without vivo validation clinical trials. This paper summarizes current evidence vitro algae extracts isolated myeloma lines. In addition, we address application algae-derived drug carriers their synergistic against hematologic malignancies.

Algal nanobionics to enhance value added products – A review

Current Research in Biotechnology, Год журнала: 2023, Номер 5, С. 100124 - 100124

Опубликована: Янв. 1, 2023

Microalgae nanobionics is a new field of study that combines nanotechnology and plant biology. are single celled, photosynthetic organisms live in saltwater or freshwater convert solar energy to chemical through the process photosynthesis. The site photosynthesis plants chloroplast. Chloroplast traps sunlight converts it into form food for algae cells. By acting as an artificial system boost capacity, electron transport photosystems, pigment content, light absorption across UV–visible spectrum, has been shown benefit plants. As result, current aims review approach microalgae, their uptake integration with chloroplasts, modulation process, effect on high value-added compounds microalgae. Major challenges potential opportunities related utilization also briefly discussed.
