Selenastrum Capricornutum: Harvesting and Oil Extraction, for Biodiesel Production
An alternative for biodiesel production is the use of lipids from microalgae. Although all steps to obtain this biofuel are important, harvesting and extraction are the most important. Advances in these areas are necessary in order to obtain third-generation fuels.

The Effect of the Herbicide Glyphosate on the Growth of Selenastrum Capricornutum
The herbicide glyphosate (MON-0139), an isopropylamine salt of N- (phosphonemethyl)glycine, was tested to determine its effects on the growth of the fresh water green alga Selenastrum capricornutum. Experiments were carried out to determine algicidal, algistatic, and inhibitory concentrations of the compound.

Changes in algal nitrogen status that increase algal lipid content also affect the bioconcentration of hydrophobic organic compounds (HOCs). Bioconcentration factors (BCFs) for several HOCs increased up to nine times as the total algal lipid content of the green algae Selenastrum carpricornutum increased from 17 to 44% of the algal dry weight as a ...
