Microalgae, as biodiesel feedstock, are promising renewable energy sources that can be continuously developed into the future. Because recovery of microalgal lipid from dry microalgae incurs high costs, particularly in the dewatering process, wet extraction has been suggested as an attractive...

Oil extraction from microalgae stands as a huge challenge for bioproducts and biofuels production, mainly due to high costs and energy requirement. In this study, maximum cell density, growth curve, lipid content, daily biomass and oil productivities were determined for Chlorella minutissima,...

Simple criteria, guidelines and models are established for free water surface (FWS) constructed wetland selection and preliminary sizing. The analysis employs models for FWS constructed wetland design, considering simultaneously the removal requirements and the hydraulics of the system. On the...

Several technologies for microalgae oil extraction are being evaluated in order to find the most adequate for large scale microalgae processing. In this work, exergy analysis was used as an instrument for screening three design alternatives for microalgae oil extraction in a large-scale process...

Increasing trends in global warming already evident, the likelihood of further rise continuing, and their impacts give urgency to addressing carbon sequestration technologies more coherently and effectively. Carbon dioxide (CO<Subscript>2</Subscript>) is responsible for over half the warming potential of all...</subscript>

Pioneering the works of Brookman (1975), Middelberg et al. (1992a, 1992b) and Kleinig and Middelberg (1996), on cell disruption of yeast through HPH (high pressure homogenizer), the underlying factors in improving energy yield from biomass source has to be considered. This has become a global...

Third generation biodiesel production from microalgae currently necessitates many stages, some of which are complex and energy consuming, cell disruption is such an example. Microalgal strains which are prime candidates for oil extraction normally possess a robust cell wall which prevents the...

The production of alternative fuels from microalgae involves lengthy processing steps. Cell disruption is an integral part of the downstream pool of unit operations as it facilitates the release of intracellular products essential for biofuel production. This study investigated the use of...

The increase in the world's energy demand has contributed to the emergence of new sustainable energy sources, such as microalgae, with their great potential to provide biofuels and other high value co-products for the food and health's markets. However, current biorefinery methodologies are...

The role of microwave treatment as a precursor to lipid extraction from Nannochloropsis oculata using solvent extraction was investigated. Two microwave power settings were used, corresponding to wall plug powers of 635 and 1021 W. To limit the maximum temperature rise of the wet algal...
