Approach to biomass production of the marine microalga Tetraselmis suecica (kylin) butch using common garden fertilizer and soil extract as cheap nutrient supply in batch cultures
Fábregas, Jaime; Toribio, Luisa; Abalde, Julio; Cabezas, Buenaventura; Herrero, Concepción (Elsevier Applied Science Publishers, 1987)We report the possibility of an economic cultivation of the marine microalga Tetraselmis suecica, using different mixtures of a common garden fertilizer, soil extract, micronutrients and vitamins. Maximum cellular densities ... -
Biomass production and biochemical composition in mass cultures of the marine microalga Isochrysis galbana Parke at varying nutrient concentrations
Fábregas, Jaime; Herrero, Concepción; Cabezas, Buenaventura; Abalde, Julio (Elsevier Science Publishers, 1986)Mass cultures of Isochrysis galbana were carried out with four nutrient concentrations ranging from 2 to 16 mM of NaNO3 and salinity 35‰. An air flow of 15 l/min maintained a CO2 transference rate sufficient to keep the ... -
Biomass production and biochemical variability of the marine microalga Dunaliella tertiolecta (Butcher) with high nutrient concentrations
Fábregas, Jaime; Herrero, Concepción; Abalde, Julio; Cabezas, Buenaventura (Elsevier Science Editors, 1986)Mass cultures of Dunaliella tertiolecta were carried out in 10-l flasks with four nutrient concentrations in order to obtain a maximum biomass production and to find out its biochemical variability. Using these cultural ... -
Changes in protein, carbohydrates and gross energy in the marine microalga Dunaliella tertiolecta (Butcher) by nitrogen concentrations as nitrate, nitrite and urea
Fábregas, Jaime; Abalde, Julio; Cabezas, Buenaventura; Herrero, Concepción (Elsevier Science Publishers, 1989)Cultures of the marine microalga Dunaliella tertiolecta were grown in nitrate, nitrite and urea at concentrations ranging from 0·25 to 16 mg atom. N/litre. Great biochemical variability has been shown in this microalga ... -
Changes in the gross chemical composition of mass cultures of the marine microalga Dunaliella tertiolecta with different aeration rates
Fábregas, Jaime; Ferrón, Lucía; Abalde, Julio; Cabezas, Buenaventura; Otero, Ana (Elsevier, 1995)The effect of different aeration rates, in the range 0–6·51 l of air min−1 l of culture−1, and CO2 supply on the biochemical composition of mass cultures of the marine microalga Dunaliella tertiolecta was studied. The ... -
Decrease in plasma cholesterol, triglycerides and CPK levels in rats fed on the marine microalga Dunaliella tertiolecta
Fábregas, Jaime; Herrero, Concepción; Parafita, Manuel; Paz, José Manuel; Cabezas, Buenaventura; Abalde, Julio (Geor Thieme Verlag, 1986)The dried marine microalga Dunaliella tertiolecta was fed to weaning albino rats for 12 days as the sole protein source at a protein level of 12% protein from casein. Plasma cholesterol, triglycerides, and CPK levels were ... -
Growth and biochemical variability of the marine microalga Chlorella stigmatophora in batch cultures with different salinities and nutrient gradient concentration
Fábregas, Jaime; Herrero, Concepción; Cabezas, Buenaventura; Abalde, Julio (Taylor & Francis Group, 1987-03-30)[Abstract] Chlorella stigmatophora was cultured under 56 different combinations of nutrient-salinity concentrations, ranging from 1 to 64 mM NaNO3 and from 0 to 35%. salinity. Optimal growth conditions for obtaining maximum ... -
Growth of the marine microalga Tetraselmis suecica in batch cultures with different salinities and nutrient concentrations
Fábregas, Jaime; Abalde, Julio; Herrero, Concepción; Cabezas, Buenaventura; Veiga, Manuel (Elsevier Science Publishers, 1984)The marine microalga Tetraselmis suecica is known for its ability to tolerate a wide range of salt concentrations. Cultures were grown under 48 different nutrient concentration-salinity conditions, ranging from 2 to 64 mM ... -
