| The present paper examines a long-run relationship between the energy, bioenergy and food prices. In the recent years the bioenergy production has increased significantly around the world. The increase has been driven by rising energy prices as well as by environmental policies aiming at reducing the harmful effects of conventional sources of energy, such as climate change. Bioenergy, in turn, affects agricultural markets, because it uses agricultural commodities as inputs. The theoretical model we develop predicts that, because of price inelastic food demand, the agricultural price increase may be substantial. The empirical findings confirm the theoretical hypothesis that energy prices do affect prices of agricultural commodities. However, the... |

| The chemical screening carried out on Schizochytrium sp. biomass led the identification of 24 types of organic compounds belonging to n-alkanes, 1-alkenes, 1-alkanols, free fatty acids, methyl and ethyl esters of saturated and unsaturated fatty acids, saturated tri- and diglycerides, unsaturated monoglycerides, wax esters, sterols, triterpenes, and mono- and sesquiterpenes. Moreover, a sample containing fully saturated ethyl biodiesel was obtained experimentally with a yield of 28.72% w/w of the crude extract, and an average chain length of 15.52 carbons. This strain produced no toxins, but showed important nutrients, making it potentially applicable to the field of functional food, and biodiesel production. |
