Culture of the marine diatom Phaeodactylum tricornutum with different nitrogen sources: Growth, nutrient conversion and biochemical composition
Fidalgo Paredes, Pablo; Cid, Ángeles; Abalde, Julio; Herrero, Concepción (Station Biologique de Roscoff, 1995)[Abstract] Cultures of the marine diatom Phaeodaetylum trieornutum were grown in nitrate, nitrite, ammonia or urea media. Nitrogen transformation efficiencies were close to 100% in cultures with nitrate, nitrite or urea, ... -
Effects of nitrogen source and growth phase on proximate biochemical composition, lipid classes and fatty acid profile of the marine microalga "Isochrysis Galbana"
Fidalgo Paredes, Pablo; Cid, Ángeles; Torres, Enrique; Sukenik, A.; Herrero, Concepción (1998-07)[Abstract]The marine microalga Isochrysis galbana was cultured in nitrate, nitrite or urea media to examine changes in the gross biochemical composition, with special emphasis on the growth phase associated changes in the ... -
Growth and biochemical profile of juvenile mussels (mytilus galloprovincialis Lmk) fed on different algal diets
Fidalgo Paredes, Pablo; López Muñoz, I.; Abalde, Julio; Herrero, Concepción (National Shellfisheries Association, 1994)The food value of different microalgal diets to juvenile Mytilus galloprovincialis Lmk was assessed. Three different marine microalgae species (Tetraselmis suecica, Dunaliella tertiolecta and Phaeodactylum tricornutum) ... -
Long-chain class III metallothioneins as a mechanism of cadmium tolerance in the marine diatom Phaeodactylum tricornutum Bohlin
Torres, Enrique; Cid, Ángeles; Fidalgo Paredes, Pablo; Herrero, Concepción; Abalde, Julio (1997-11)Cadmium tolerance of the marine diatom Phaeodactylum tricornutum Bohlin was studied. P. tricornutum growth was significantly reduced by cadmium concentrations of 5 mg l−1 or higher. The EC50 value was 22.39 mg l−1 of cadmium ... -
Microalgas: cultivo y aplicaciones
Abalde, Julio; Cid, Ángeles; Fidalgo Paredes, Pablo; Torres, Enrique; Herrero, Concepción (Universidade da Coruña, Servizo de Publicacións, 1995)[Resumen] Esta obra ofrece una amplia y detallada panorámica de las microalgas, su cultivo (parámetros, especies utilizadas, sistemas y procedimientos) y las aplicaciones que pueden tener en la nutrición animal, la ... -
Production and analysis of secondary carotenoids in green algae
Orosa García, Miguel; Torres, Enrique; Abalde, Julio; Fidalgo Paredes, Pablo (Springer, 2000-10)The microalgae Neochloris wimmeri, Scenedesmus vacuolatus, Scotiellopsis oocystiformis, Chlorella zofingiensis and Protosiphon botryoides were grown under secondary carotenoid inductive conditions. The results indicate ... -
Rapid assay for the analysis of class III metallothioneins by capillary zone electrophoresis in crude extracts of microalgal cells exposed to cadmium
Torres, Enrique; Cid, Ángeles; Fidalgo Paredes, Pablo; Abalde, Julio (Elsevier, 1997-07-18)An optimization strategy for the separation and analysis of class III metallothioneins from a complex matrix by capillary zone electrophoresis (CZE) is presented and illustrated. Metallothioneins are a group of polypeptides ... -
Tolerance and detoxification mechanisms in marine diatom Phaeodactylum tricornutum exposed to cadmium
Torres, Enrique; Cid, Ángeles; Fidalgo Paredes, Pablo; Herrero, Concepción; Abalde, Julio (Springer, 1995)Tolerance is one of the most important mechanisms for survival. Organisms living in polluted environments with heavy metals develop tolerance to these contaminants; this tolerance has been attributed to the ability to ... -
Toxic action of copper on the membrane system of a marine diatom measured by flow cytometry
Cid, Ángeles; Fidalgo Paredes, Pablo; Herrero, Concepción; Abalde, Julio (WILEY-Liss, 1996-09)Flow cytometric measurements were used to investigate the toxic action of copper on some Phaeodactylum tricornutum membrane systems. Throughout the time of metal exposure, the percentage of viable cells decreased as copper ... -
Variabilidad bioquímica de microalgas marinas en cultivo en función de la fuente de nitrógeno
Fidalgo Paredes, Pablo (1995)[Resumen] Se cultivan cinco microalgas marinas con cuatro fuentes de nitrogeno: nitrato, nitrito, amonio y urea. Crecimiento, productividad y composicion bioquimica varian significativamente en funcion de la fuente ... -
Variations in the biochemical profile of the marine microalga Dunaliella tertiolecta (Butcher) cultured with different nutrient concentrations and urea as a nitrogen source
Herrero, Concepción; Abalde, Julio; Cid, Ángeles; Fidalgo Paredes, Pablo; Fábregas, Jaime (Station Biologique de Roscoff, 1994)[Abstract] Variations in the biochemical profile of the marine microalga Dunaliella tertiolecta (Butcher) cultured with different nutrient concentrations and urea as a nitrogen source. Cultures of the marine microalga ...
