In the last decades, different photosynthetic organisms were identified which can exploit longer wavelength photons to drive photosynthesis; both academia and industry showed a renewed interest in trying to couple it with existing photosynthetic bioprocesses, with the objective of achieving higher productivities. These organisms benefit from an extended absorption range (up to 750 nm) that would
Polyextremophile acidophilic microalgae are a unique class of microorganisms that thrive in extreme environments with extremely low pH levels and high temperatures. These organisms are capable of surviving in very harsh conditions, making them potentially useful, for instance, in the mining and metal recovery industries. The acidity of the growing media hinders the development of
Microalgal biotechnology and the production of microalgae-derived products are promising technologies in the industrial transformation to create a more circular and biobased economy with net zero carbon footprint. For the production of microalgae, many process conditions have to be controlled according to specific environmental requirements by the microalgal strain of interest. These requirements include for
Temperature and light intensity are the main factors affecting microalgae growth in unlimited nutrient conditions. The approach of assuming temperature and light intensity as two independent factors in photosynthesis models is generally accepted— however, a weak coupling between both variables is already observed at low light intensities, while limited data about the joint effect of
Microalgae are photosynthetic microorganisms able to convert light energy and inorganic nutrients into high-value compounds such as fatty acids, polysaccharides, or carotenoids. Astaxanthin, a red carotenoid pigment, is a very attractive molecule due to its antioxidant properties, which are significantly stronger than those of other carotenoids and vitamins. It has numerous applications in various industries,
