effects of various fertilizers such as farmyard manure (fm), urea, and plant growth promoting rhizobacteria (pgpr, including the genera azotobacter and azospirillium) were checked on yield, fatty acids, protein, and oil contents of sunflower. a two-year field experiment was conducted in a semi-arid region in iran in 2007 and 2008. the experiment was a split plot in a randomized complete block d...

An efficient microwave-assisted simultaneous distillation and extraction (MA-SDE) method has been developed for the separation of polysaccharides and essential oil from Taxus chinensis var. mairei. The key operating parameters for MA-SDE were optimized by single factor and central composite design experiments, and the optimal conditions were found to include a particle size of 60–80 mesh, liqui...

Herein, the data acquired regarding the preliminary and exploratory experiments conducted with potato peel as a biomass source for the direct thermochemical liquefaction is disclosed. The procedure was carried out in a 2-ethylhexanol/DEG solvent mixture at 160 °C in the presence of p-Toluenesulfonic acid. The adopted procedure afforded a bio-oil in high yield (up to 93%) after only 30 min. For ...

Biodiesel production from vegetable oil has gained attention as an alternative fuel to minimize the usage of fossil fuels and reduce greenhouse gases pollution. In Malaysia, oils from local fruit seeds of papaya and rambutan are potential feedstock for biodiesel production due to their high lipid contents and easily available. In the present study, papaya and rambutan seed oils were extracted v...

This study was aimed at evaluating the capability of Yarrowia lipolytica W29 for the synthesis of lipolytic enzymes in a medium containing plant oils from non-conventional sources with some components displaying bioactivity. Oils from almond, hazelnut, and coriander seeds were obtained by using n-hexane (Soxhlet method) and a chloroform/methanol mixture of solvents (Folch method), and their eff...
