Microalgae are capable of synthesizing high levels of triacylglycerol (TAG) which can be used as precursor compounds for fuels and specialty chemicals. Algal TAG accumulation typically occurs when cellular cycling is delayed or arrested due to nutrient limitation, an environmental challenge...

Using a panel of 48 provinces for four years we empirically analyze a series of temporary and permanent policies aimed at curbing fuel consumption implemented in Spain between March and June 2011. The first policy was a reduction in the speed limit in highways. The second policy was an increase...

The rapid expansion of the biofuel industry diverts a large amount of agricultural crops as energy feedstocks, and in turn affects farm land allocation, feedstock market equilibrium, and agricultural economic development in local areas. In this paper, we propose game-theoretic models that...

Increasing scarcity of oil reserves and the high CO2 emissions from using oil have contributed to the development of renewable biofuels. Pulp and paper mill integrated forest biorefineries offer one important means to increase biofuel production. This study analyzes the effects of policies to...

With many of the poor people in Brazil living in rural areas, local governments have intensified their efforts to design and implement effective policies that boost rural development. In 2004, a national program for production and use of biodiesel was launched aiming at increasing income among...

To select microalgae with a high biomass, chlorophyll a, lipid, and fatty acid content of two mutants (LARB-202-2 and LARB-202-3) and their parent wild type of the unicellular green alga Nannochloropsis sp were cultured with air containing 1% CO2 for a week in 1L bubbled tubes with continuous...

Interest in the use of microalgae for the production of biofuels has grown in recent years. Biomethane is a biofuel that can be obtained with high efficiency from anaerobic digestion of various organic feedstocks. In this study, a selection of freshwater (n=15) and marine (n=5) microalgae were...

Dual-injection strategies in spark-ignition (SI) engines allow the in-cylinder blending of two different fuels at any blend ratio, when simultaneously combining port fuel injection (PFI) and direct-injection (DI). This offers increased flexibility and the potential to optimize the combustion...

Botryococcus braunii (B. braunii), a green colonial microalga, is one of the most potentially significant renewable energy sources, because of its high productivity of hydrocarbon oils. In order to maximize energy utilization from this alga, it should be important to recover energy from not only...
