Otero Casal, Ana MaríaPereira Bouzas, Simón2020-07-312020-09-282020http://hdl.handle.net/10347/23237In this work the author has studied the influence of light composition on growth, pigment content and photosynthetic response in four microalgae species with commercial interest: the Chlorophyta Haematococcus pluvialis, Dunaliella salina, and Dunaliella tertiolecta, and the Rhodophyta Porphyridium cruentum. The results show how light composition is a parameter that may largely influence the production of compounds with industrial interest. Therefore, the use of a specific light spectrum is confirmed as an important tool for the optimization of artificial-light microalgae cultivation. Moreover, the work has been carried out in an industrial environment and shows the upscaling of a two-stage H. pluvialis cultivation as a proof of concept of the aforementioned, at a pilot-scale.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/MicroalgaeCulture optimizationLight compositionMaterias::Investigación::33 Ciencias tecnológicas::3302 Tecnología bioquímica::330203 Microbiología industrialMaterias::Investigación::24 Ciencias de la vida::2414 Microbiologíadoctoral thesisopen access
