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 ... -

Abalde, Julio; Orosa García, Miguel; Torres, Enrique; Cid, Ángeles (Universidade da Coruña, 1999) -
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 ... -
Potential use of flow cytometry in toxicity studies with microalgae
Franqueira, Dolores; Orosa García, Miguel; Torres, Enrique; Herrero, Concepción; Cid, Ángeles (2000-03)[Abstract]Cytotoxic effects of aquatic pollutants on microalgae are very heterogeneous, and they are influenced by environmental conditions and the test species. Stress produced by copper or paraquat addition to the culture ... -
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 ... -
Purification and characterization of phycocyanin from the marine cyanobacterium Synechococcus sp. IO9201
Abalde, Julio; Betancourt, Liliana; Torres, Enrique; Cid, Ángeles; Barwell, Clive (Elsevier, 1998-08-07)This paper describes a suitable method for the optimum extraction and isolation of phycocyanin from the cyanobacterium Synechococcus sp. IO9201 isolated from Caribbean waters. Phycocyanin from this microorganism was purified ... -
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 ... -
Removal of cadmium ions by the marine diatom Phaeodactylum tricornutum Bohlin accumulation and long-term kinetics of uptake
Torres, Enrique; Cid, Ángeles; Herrero, Concepción; Abalde, Julio (Elsevier, 1998-03)The marine diatom Phaeodactylum tricornutum Bohlin was exposed to different cadmium concentrations (1–100 mg l−1) for 4 days. The amount of cadmium removed was recorded, with particular attention paid to long-term uptake ... -
Response of the marine microalga Dunaliella tertiolecta (Chlorophyceae) to copper toxicity in short time experiments
Abalde, Julio; Cid, Ángeles; Reiriz, S.; Torres, Enrique; Herrero, Concepción (Springer, 1995-02)Heavy metals are introduced into aquatic ecosystems from industrial wastes, agricultural runoff and mining activities. The toxicity of heavy metal ions in solution to microalgae is well known. The essentiality and toxicity ... -
Sorption isotherm studies of Cd(II) ions using living cells of the marine microalga Tetraselmis suecica (Kylin) Butch
Pérez Rama, Mónica; Torres, Enrique; Suárez, Cristina; Herrero, Concepción; Abalde, Julio (2010-10)[Abstract]The present work reports the use of living cells of the marine microalga Tetraselmis suecica for the biosorption of cadmium ions. For a better understanding of the biosorption characteristics, three fractions of ... -

Sulphate, more than a nutrient, protects the microalga Chlamydomonas moewusii from cadmium toxicity
Mera, Roi; Torres, Enrique; Abalde, Julio (Elsevier, 2014-03)Sulphur is an essential macroelement that plays important roles in living organisms. The thiol rich sulphur compounds, such as cysteine, γ-Glu–Cys, glutathione and phytochelatins participate in the tolerance mechanisms ... -
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 ...
