Rotating green to red: a biofilm-based approach to astaxanthin production

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,

Data mining approaches for monitoring and decision support of indoor microalgae production

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

Spectroscopic on-line biosensors for monitoring and control of microalgal cultivations

Microalgae are well known photosynthetic microbes used as cell factories for the production of relevant biotechnological compounds (e.g. pigments, unsaturated fatty acids) and environmental applications (e.g. wastewater treatment, lipids for biofuel). Despite these outstanding characteristics, industrial scale production of microalgae is still at an early stage of development. Moreover, the economically viable support of the

Modeling and control of microalgae-based wastewater treatment

Microalgal biomass is increasingly gaining interest in new emerging sectors such as biogas and biodiesel production, animal and aqua feed, biopesticides, pharmaceuticals and biofertilizers. Apart from biomass production, starting from the 1960s, microalgae were studied as a new water remediation technology, with the advantage of guaranteeing fewer greenhouse gas production, less energy demand and costs,

DigitAlgaesation summer schools

Between 1st and 8th July 2022, Wageningen (Netherlands) hosted the 7th International Course on Microalgae Process Design, organised by Graduate School VLAG in co-operation with Bioprocess Engineering and AlgaePARC (Wageningen University & Research). All ESRs took part in the summer school and had the opportunity to increase their knowledge on the several types of bioreactors
