Entrapment of marine microalga, Isochrysis galbana, for biosorption of Cr(III) from aqueous solution: isotherms and spectroscopic characterization

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...

The isolation and antioxidant activity of polysaccharides from the marine microalgae Isochrysis galbana.

Three polysaccharides, IPSI-A, IPSI-B and IPSII, were successfully isolated from the marine microalgae Isochrysis galbana through a combination of anion-exchange column chromatography and repeated gel chromatography. These three polysaccharides were demonstrated to have moderate scavenging activities against superoxide and hydroxyl radicals and moderate reductive power in a concentration-depend...

Cultivation 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...

Modelling 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 ...
