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,
Microalgae are rich sources of protein, lipids, carbohydrates, and pigments. During the last decades, they emerged as a sustainable source of raw materials in the food, feed (aquaculture), nutraceuticals, medicinal and cosmetic industries. The high production cost associated with industrial microalgae manufacturing is a pressing concern that challenges their adoption as a viable source of
