To enhance energy production efficiency (EPE) from microalgae Chlorella pyrenoidosa (CP), cassava starch (CS) was mixed with CP to optimise the carbon/nitrogen (C/N) ratio and facilitate efficient dark hydrogen fermentation, followed by photo hydrogen fermentation and methanogenesis. Steam...

Some strains of Rhodosporidium toruloides can produce high concentrations of single cell oil. However, this oleaginous yeast does not produce amylases. Cells of the amylase-producing yeast Saccharomycopsis fibuligera A11-c were immobilized using polyvinyl alcohol. The immobilized yeast could...

After the lipid contents in 7 strains of Rhodosporidium toruloides were determined, R. toruloides 21167 among them was found to be able to produce the highest amount of lipid in its cells. Many ions, such as Mn2+, Ca2+, Zn2+ and Fe3+ had positive effects on lipid accumulation by R. toruloides...

Energy and exergy analyses of native cassava starch drying in a tray dryer were carried out to assess the performance of the system in terms of energy utilization, energy utilization ratio, energy efficiency, exergy inflow and outflow, exergy loss and exegetic efficiency. The results indicated...

In this paper we propose an innovative methodology that aims to solve drawbacks related to how patent data are allocated and organized in international databases. We propose as a case study the biofuels sector, in order to evaluate the validity of such a method. Starting with a systematic...

The issue of production of raw materials for energy generation on agricultural areas is a multileveled issue (the economic, social, environmental and other aspects should be considered). Plantations of energetic plants that represent an important component in satisfying the increasing demand for...
