Biomass production and biochemical variability of the marine microalga Isochrysis galbana in relation to culture medium.
We have studied the autotrophic growth of the marine microalga, Isochrysis galbana Parke, in a batch photobioreactor, comparing five different culture media and analysing the influence of each on growth kinetics as well as on the fatty-acid composition and protein content of the biomass. All the experiments were performed at 15 degrees C, with the culture medium at pH 8.0, a specific rate of ai...
متن کاملModelling neutral lipid production by the microalga Isochrysis aff. galbana under nitrogen limitation.
This article proposes a dynamical model of microalgal lipid production under nitrogen limitation. In this model, intracellular carbon is divided between a functional pool and two storage pools (sugars and neutral lipids). The various intracellular carbon flows between these pools lead to a complex dynamic with a strong discrepancy between synthesis and mobilization of neutral lipids. The model ...
متن کاملCultivation of Isochrysis galbana in Phototrophic, Heterotrophic, and Mixotrophic Conditions
This study compared the growth and biomass production of Isochrysis galbana under hetero-, mixo-, and phototrophic conditions using different organic carbon sources. The growth of I. galbana was inhibited in heterotrophy but was enhanced in mixotrophy compared to that in phototrophy. Subsequently, the influences of organic carbon and environmental factors (light and salinity) on the growth of I...
متن کاملFatty Acid Characteristics of Isochrysis galbana Lipids Extracted Using a Microwave-Assisted Method
Lipids were extracted from Isochrysis galbana using a microwave-assisted method accompanied by various types of organic solvents. The effects of organic solvent type and microwave input energy on the fatty acid characteristics of the extracted lipids and their biodiesel product were investigated. Variations in the characteristics of the lipids extracted using a combination of n-hexane and iso-p...
متن کاملEnhancement of neutral lipid productivity in the microalga Isochrysis affinis Galbana (T-Iso) by a mutation-selection procedure.
Microalgae offer a high potential for energetic lipid storage as well as high growth rates. They are therefore considered promising candidates for biofuel production, with the selection of high lipid-producing strains a major objective in projects on the development of this technology. We developed a mutation-selection method aimed at increasing microalgae neutral lipid productivity. A two step...
