Some microalgae are particularly attractive as a renewable feedstock for biodiesel production due to their rapid growth, high content of triacylglycerols, and ability to be grown on non-arable land. Unfortunately, obtaining oil from algae is currently cost prohibitive in part due to the need to pump and process large volumes of dilute algal suspensions. In an effort to circumvent this problem, ...

Renewable and carbon neutral biofuels are necessary for environmental and economic sustainability. The viability of the first generation biofuels production is however questionable because of the conflict with food supply. Microalgal biofuels are a viable alternative. The oil productivity of many microalgae exceeds the best producing oil crops. This paper aims to analyze and promote integration...

of a thesis at the University of Miami. Thesis supervised by Professor Andrew Baker. No. of pages in text. (46) The Deepwater Horizon (DWH) blowout of 2010 exposed many coastal and marine ecosystems in the Gulf of Mexico (GoM) to the acute and chronic effects of crude oil. To date, no studies have investigated the toxicity of DWH oil on shallow reef-building corals despite the relative proximit...

Ileana Callejas discusses how remote sensing can be used to monitor water quality in coastal regions,including tracking sewage plumes, algal blooms and oil spills.

Energy in algal oil 37.90 Energy in biogas from residual biomass 50.00 Estimated as 22.85 MJ kg 1 of urea and 2.94 MJ kg 1 of diammonium phosphate. Using sedimentation followed by continuous vacuum belt filters. Approximate only in view of the developmental nature of algal oil recovery processes. Estimated as 80.4 MJ m 2 of facility area divided by a 20 year working life and the mass of oil pro...

Microalgae offer great promise to contribute a signifi cant portion of the renewable fuels that will be required by the Renewable Fuels Standard described in the 2007 Energy Independence and Security Act of the United States. Algal biofuels would be based mainly on the high lipid content of the algal cell and thus would be an ideal feedstock for high energy density transportation fuels, such as...

Background In this study, a two-step processing method (hydrothermal liquefaction followed by catalytic upgrading) was used to produce upgraded bio-oil. A comprehensive screening analysis of algal species, including four microalgae and four macroalgae, was conducted to bridge the gap between previous accounts of microalgae and macroalgae hydrothermal liquefaction and the upgrading process of th...

Algae are widely used as biosorbent for the sorption of heavy metals, however sorption of oil on algae has not been explored. Algae in marine and fresh water environment may affect the fate and transport of spilled oil. Sorption of diesel and lubricating oil was studied using dead biomass of Spirulina sp. and Scenedesmus abundans. The rate and extent of sorption was studied in well mixed batch ...
