Laboratory Science High School. College of Education. Cavite Slate University, Indang, Cavite. May 2018. Adviser: Dr. Ruel M. Mojica. This study focused on producing and characterizing bioethanol from corn cobs since the sugar content of the cobs and availability make them effective sources for bioethanol Production. Specifically, this study tested the effects of varying pH level during fermentation on the characteristic of the bioethanol produced. Oven-drying, grinding. soxhlet extraction, fermentation, and distillation are the procedures underwent by the corcobs. During the fermentation process, the pH level was varied from pH 4 to pH 6 using Hydrochloric acid and Sodium hydroxide. The derived bioethanol were characterized for their sensory, physical, and chemical properties. The sensory properties of the samples showed that all samples were discovered to be as clear as the commercial ethanol, and all had an acceptable odor. Results of the physical analysis and chemical showed that fermentation at pH 6 produced optimum samples with the closest properties to the commercial ethanol. Based on the results of the physical and chemical analyses, it can be concluded that corncobs are feasible sources of bioethanol. However, statistical analysis showed that significant difference did not occur- among the three treatments. Lastly, a variation in the procedure might have affected the results obtained in the study.
