The research was conducted in the laboratories of the Agricultural Technical College/Mosul during the period from October 2023. The aim was to produce distilled ethanol from yellow and white corn in Iraq. The research included collecting parts (fruits, seeds, and leaves), transferring them to the Agricultural Technical College in the laboratory, and storing them in sterile nylon bags. The fermentation treatments were divided into 6 treatments to carry out fermentation processes by adding a 2% solution of Saccharomyces cerevisiae yeast to the leaves, fruits, and seeds of corn that were previously prepared and sterilized for fermentation. They were placed in fermenters, and after completing fermentation, carbon dioxide CO2 and ethanol CH3CH2OH were measured, and then the mixture was fractionally distilled to obtain pure ethanol. The results of the productivity experiment treatments after 72 hours showed that the treatment (yellow corn leaves + 2% yeast) gave the highest production of CO2 gas, 220800 ml, and ethanol, 3.61%, while the treatment (white corn fruits + 2% yeast) gave the lowest production of CO2 gas, 131840 ml, and ethanol, 2.15%. After conducting fractional distillation on approximately 15 liters of yeast resulting from this experiment for each treatment, the results showed that the percentage of alcohol distilled was 90%. The highest volume obtained from the yellow corn leaves treatment was 540 ml, while the lowest volume obtained from the white corn fruits + 2% yeast treatment was 322 ml. Based on the results, genetically modified yeast strains can be used to increase efficiency and improve the biofuel production process.
