(Asociación española de ecología terrestre, 2008-04)La eutrofización de los pantanos destinados al abastecimiento de agua de consumo humano supone un deterioro de la calidad de la misma, e incluso puede afectar a la salud de los consumidores. Éste es el caso de la presencia ... -
Cultivation of Microalgae Chlorella Using Wine Industry by-Products
(MDPI, 2021-01)An approach of new and sustainable uses for by-products generated in the wine production industry, one of the agro-food sectors of importance, has been studied. Wine lees, a sediment obtained in different processes of ... -
Enhancement of carotenoid production in Nannochloropsis by phosphate and sulphur limitation
(Formatex, 2007)Because of its value as antioxidants, food-supplements and in animal-feeding, carotenoids are among the most attractive target compounds of marine microalgae. In this contribution the influence of essential nutrients (N, ... -
Enhancement of Lutein Production in Chlorella sorokiniana (Chorophyta) by Improvement of Culture Conditions and Random Mutagenesis
(MDPI, 2011-09)Chlorella sorokiniana has been selected for lutein production, after a screening of thirteen species of microalgae, since it showed both a high content in this carotenoid and a high growth rate. The effects of several ... -
Estudio y manipulación genética de la ruta de carotenoides en "Chlamydomonas Reinhardtii" mediante la expresión de genes exógenos
(Universidad de Huelva, 2012)Los carotenoides son un grupo de pigmentos isoprenoides sintetizados por todos los organismos fotosintéticos y algunas bacterias y hongos. Los animales y otros organismos que no los producen in vivo deben incluirlos en ... -
Exploring Nordic microalgae as a potential novel source of antioxidant and bioactive compounds
(Elsevier, 2023)Nordic microalgae are a group of photosynthetic organisms acclimated to growth at low temperature and in varying light conditions; the subarctic climate offers bright days with moderate temperatures during summer and cold ... -
