scholarly journals The effect of changes in opportunity costs and prices of some agricultural products such as sugar beet, corn,wheat etc. used for bioethanol production on the cost of bioethanol production is not adequately known in Turkey.. Therefore, it was aimed to determine the bioethanol production cost items and unit production costs and also to put forth the effects of variations in raw material prices on cost of bioethanol.. The research data were collected via personal interviews from active bioethanol plants in Turkey. The results of previous studies and documents of related institutions and organizations were also used. The study followed classical cost analysis approach to calculate production cost. Scenario analysis was performed when exploring the effect of raw material prices on bioethanol production cost. Research findings showed that production cost per litre bioethanol produced from sugar beet molasses, corn, wheat and corn-wheat mixture were 2.50 TL, 2.84 TL, 2.95 and 2.84 TL, respectively. The share of raw material expenses in bioethanol cost per liter varied associated with the crops used in the process, it was 28.55% for bioethanol produced from sugar beet molasses, 44.81% for bioethanol produced from corn-wheat mixture and 44.87% bioethanol produced from corn. The research results also showed that the changes that occur in raw material prices significantly affected the bioethanol production cost and opportunity cost of crops created difficulties in biomass supply. Implementing the suitable policies and strategies and making the necessary arrangements in legislation would enhance the economic sustainability of bioethanol production in Turkey.

Abstract A bench scale submerged fermentation process was used to bioethanol produce using sugar beet molasses and Saccharomyces cerevisiae, as substrate and microbial strain, respectively. Effects of selenium amount on growth of S. cerevisiae and bioethanol production were evaluated. The obtained results indicated that growth of S. cerevisiae (manifested as turbidity intensity) in the samples containing 0, 5, 10, 15, 20 and 25 μg sodium selenite, during aerobic process, was 0.1707, 0.1678, 0.1679, 0.1664, 0.1627 and 0.160% a.u./h (after 14 h incubation), respectively. Statistical analysis based on compression test indicated that there were insignificant (p > 0.05) differences between growth rate of the yeast in the fermented samples containing S. cerevisiae and 5 to 25 μg selenium salt. Response surface methodology was utilized to evaluate effects of two fermentation parameters namely, amount of selenium (5-25 μg) and substrate brix (10-25°Bx) on the concentration (g/L) of produced bioethanol. Obtained results revealed that maximum bioethanol concentration (55 g/L) was achieved using 15 μg selenium and molasses with 25°Bx. Furthermore, results have also indicated that, without using selenium and using molasses with 25°Bx, bioethanol with concentration of 29 g/L was produced.
