An internally radiating photobioreactor was applied for the production of astaxanthin using the unicellular green alga Haematococcus pluvialis. The cellular morphology of H. pluvialis was significantly affected by the intensity of irradiance of the photobioreactor. Small green cells were widespread under lower light intensity, whereas big reddish cells were predominant under high light intensity. For these reasons, growth reflected by cell number or dry weight varied markedly with light conditions. Even under internal illumination of the photobioreactor, light penetration was significantly decreased as algal cells grew. Therefore, we employed a multistage process by gradually increasing the internal illuminations for astaxanthin production. Our results revealed that a multistage process might be essential to the successful operation of a photobioreactor for astaxnthin production using H. pluvialis.

(+info)A photobioreactor is not a medical term, but rather a term used in the fields of biology, engineering, and environmental science. It refers to a device or system designed for the cultivation of photosynthetic organisms such as algae, cyanobacteria, and other microorganisms using light as an energy source.
In simple terms, a photobioreactor is a bioreactor that uses light to drive the growth of photosynthetic organisms. These systems are often used in research, biotechnology, and wastewater treatment applications to produce valuable products such as biofuels, nutraceuticals, pharmaceuticals, and other high-value compounds.
While photobioreactors may not have a direct medical application, they can contribute to medical research and healthcare through the production of biomass or specific compounds that can be used in medical treatments, diagnostics, or therapeutic interventions.
Microalgae are microscopic, simple, thalloid, often unicellular organisms that belong to the kingdom Protista. They can be found in freshwater and marine environments, and they are capable of photosynthesis, which allows them to convert light energy, carbon dioxide, and water into organic compounds such as carbohydrates, proteins, and fats.
Microalgae are a diverse group of organisms that include various taxonomic groups such as cyanobacteria (also known as blue-green algae), diatoms, dinoflagellates, and euglenoids. They have important ecological roles in the global carbon cycle, oxygen production, and nutrient recycling.
In addition to their ecological significance, microalgae have gained attention for their potential applications in various industries, including food and feed, pharmaceuticals, cosmetics, biofuels, and environmental bioremediation. Some species of microalgae contain high levels of valuable compounds such as omega-3 fatty acids, antioxidants, pigments, and bioactive molecules that have potential health benefits for humans and animals.
