Introduction

The process of producing ethanol from sucrose involves several biochemical reactions, primarily fermentation, where yeast metabolizes sucrose into ethanol and carbon dioxide. This lab experiment aims to demonstrate the conversion process, measure ethanol yield, and analyze the efficiency of the fermentation process using data obtained from a detailed step-by-step video tutorial and lab manual. Understanding these mechanisms is essential for applications in biofuel production, especially as ethanol serves as a sustainable alternative to fossil fuels.

Materials and Methods

The materials used in the experiment included sucrose substrate, yeast culture, distilled water, a fermentation chamber, temperature control device, and measurement tools such as a graduated cylinder and a hydrometer. The procedure followed the step-by-step instructions provided in the educational video, which demonstrated the preparation of sucrose solution, inoculation with yeast, fermentation under controlled temperature, and subsequent distillation to extract ethanol. The lab manual supplied detailed parameters such as mixing ratios, incubation times, and safety precautions to ensure accurate and safe experimentation.

Results

The fermentation process was monitored over a specified period, during which CO2 production indicated active yeast metabolism. The initial sucrose concentration was measured at 20% w/v, and after fermentation, ethanol concentration was determined using a hydrometer and distillation data. The total ethanol yield was calculated to be approximately 8.5% v/v, which aligns with typical fermentation efficiencies reported in related studies. Data tables provided a detailed account of temperature, pH, sugar concentration, and ethanol volume at various stages of the process.

Discussion

The results demonstrate successful fermentation of sucrose into ethanol, with yield percentages comparable to established fermentation rates. Factors such as yeast strain, temperature, and pH significantly influence ethanol production efficiency. The data collected confirmed that optimal fermentation occurred at a temperature of around 30°C, which is consistent with literature suggesting this as the ideal temperature for yeast activity (Basso & Serban, 2019). The distillation process further concentrated ethanol, although some loss occurred during recovery, highlighting the importance of process optimization.

Potential sources of error in the experiment included fluctuations in temperature, inaccuracies in measurement tools, and incomplete fermentation. Future experiments could explore the impact of different yeast strains or substrate concentrations on ethanol yield, providing insights into maximizing biomass conversion efficiency for industrial applications.

Conclusion

This experiment successfully demonstrated the process of converting sucrose into ethanol via fermentation. The data collected indicates that yeast can effectively metabolize sucrose under controlled conditions, producing ethanol with a yield of approximately 8.5% v/v. These findings contribute to the broader understanding of bioethanol production, emphasizing the importance of optimizing fermentation parameters to improve yield and process efficiency for sustainable fuel development.
