Fatty Acid Profile of Microalgal Oils as a Criterion for Selection of the Best Feedstock for Biodiesel Production

Microalgae are considered to be potentially attractive feedstocks for biodiesel production, mainly due to their fast growth rate and high oil content accumulated in their cells. In this study, the suitability for biofuel production was tested for <i>Chlorella vulgaris</i>, <i>Chlor...

In this study, the suitability for biofuel production was tested for <i>Chlorella vulgaris</i>, <i>Chlorella fusca</i>, <i>Oocystis submarina</i>, and <i>Monoraphidium</i> strain. The effect of nutrient limitation on microalgae biomass growth, lipid accumulation, ash content, fatty acid profile, and selected physico-chemical parameters of algal biodiesel were analysed.
