“…In dry milling, which is the most common procedure, the dried grain is milled into a meal, which is then heated in water to liquefy the starch. Then introduce an enzyme to hydrolyze the starch into sugar, and then is added to ferment the sugar into ethanol and CO 2 [56,57]. The resulting CO 2 can be used for the production of carbonated beverages and dry ice and starch-off cereal residues can be marketed for animal feeding (DDGS).…”

Maize - Production and Use

Maize is the predominant raw material (together with sugar cane) for the production of bioethanol, the most common and widespread biofuel, and at the same time the predominant raw material for biogas production, with the highest yields in Europe. The advantage of maize biomass over other energy plants is the fact that biomass occurs after harvesting the seed and does not require the use of a different area for its development. The main drawback of the use of maize biomass is the negative effects of removing crop residues on fertility and the physical properties of the soil. Bioethanol's share of global biofuel production is over 94%, as many countries are replacing a portion of their fossil fuels with biofuels, according to international regulations. The choice of crops used as feedstock for the production of bioethanol is strongly associated with local climatic factors. About 60% of world bioethanol production is made with cane raw material in the Central and South American countries, with Brazil leading, while the remaining 40% from other crops with North America producing bioethanol almost exclusively from maize, and the EU uses as raw material raw starch (cereals and maize) as well as crops such as sugar beet and sweet sorghum.

“…Likewise, Arapoglou et al [ 8 ] obtained 18.5 g/L fermentable sugar from the enzymatic hydrolysis of potato peel waste with a group of three enzymes and produced 7.6 g/L of ethanol after fermentation. Efforts towards the use of starch-based lignocellulosic biomasses for bioethanol production are being challenged by low sugar yield from substrate, high inhibitor production, high production cost and low fermentation efficiency [ 16 ], thus highlighting the need for further optimisation.…”

“…The equations describe effects of the test variables on predicted responses, providing the assessment of relationships between test variables and predicting the combined effect of all test variables on the response. This approach enables efficient exploration of a process or a system [13] and is extensively used for optimization of bioethanol production [6,[14][15][16][17][18].…”

Bioethanol technology represents an important scientific research area because of the high market value and wide availability of its primary and by-products. Worldwide interest in utilizing bioethanol as a renewable and sustainable energy source has significantly increased in the last few years due to limited reserves of fossil fuels and concerns about climate change. Therefore, improvement of the bioethanol production process is a priority research field at the international scale, due to both economic and environmental reasons. The aim of this study was to optimize production of bioethanol from soybean molasses based media using response surface methodology. Three different strains of the yeast Saccharomices cerevisiae, commercially available in dried form, were used as production microorganisms, and the best results were obtained by using dried baker's yeast. The results of optimization of alcoholic fermentation using dried baker's yeast indicate that the highest value of the overall desirability function (0.945) is obtained when the initial sugar content is 18.10 % (w/v) at the fermentation time of 48.00 h. At these conditions the model predicts that bioethanol concentration is 8.40 % (v/v), yeast cell number 2.21·10 8 cells/mL and the residual sugar content is 0.35 % (w/v).
