Abstract: Ethiopia is one of the countries where a wide variety of traditional fermented beverages are produced and consumed for a long time. Traditional fermented beverages are indigenous & popular to a particular area and have been developed by the people using age-old techniques from locally available raw materials in southern parts of country. In this study, maize, barely, sorghum were used as ingredients respectively. Some of Ethiopian indigenous traditional fermented beverages products are borde, booka and korefe, in which fermentation is natural and involves mixed cultures of microbes. The most common fermenting microorganisms, lactic acid bacteria and yeast, are used as a catalyst, for improvement of nutritional quality, good organoleptic properties, and safety were used. The moisture, ash, protein, fat, CHO and energy ranged from 78.9 – 83.4, 0.97 -4.8, 7.3 – 9.75, 6.71 – 2.33, 2.31 – 5.47 and 78.05 – 125.95% for all samples respectively. The result of microbial activities such as E. coli, Enterobacteriaceae, Lactobacillus and coliforms in borde, korefe and booka drink were 0.51, 1.67 ×101, 1.2 ×104, and 3.67 ×105 respectively. The nature of beverage preparation in Ethiopia, traditional household processing, associated lower microorganisms with a fermented beverage, and their contribution toward improvement. Therefore, this study shows that the alcoholic contents booka (1.53±0.2) < korefe (4.21±0.2) < borede (4.67±0.2), this is due to the fermenting time during preparation. In the future, to improve its quality, it is important to standardize the methods of beverage fermentation processes and advanced technologies.

Abstract: Lignocellulosic biomass (LCB), primarily composed of cellulose, hemicellulose, and lignin, represents a valuable renewable resource. Among these components, cellulose is the most abundant biodegradable polymer, with significant industrial potential. However, its efficient isolation remains a major challenge due to its strong association with hemicellulose and lignin within the complex LCB structure. Effective pretreatment strategies are essential to overcome these structural barriers and facilitate cellulose extraction. Conventional pretreatment methods, while effective, often rely on harsh chemicals, elevated temperatures, and high energy inputs, leading to increased costs, low yields, and the formation of fermentation inhibitors, which hinder sustainable biomass utilization. In response to these limitations, environmentally friendly pretreatment approaches have been developed to enhance cellulose separation while minimizing ecological and economic drawbacks. These green methods prioritize efficient delignification, reduced solvent consumption, lower environmental impact, and alignment with sustainable technological advancements. This review explores the application of eco-friendly pretreatment techniques for cellulose isolation from diverse lignocellulosic biomass sources. It further highlights the role of cellulose as a crucial feedstock in the bioeconomy, emphasizing its versatility across various industrial sectors. By advancing sustainable cellulose extraction methods, this research contributes to the broader goal of developing environmentally responsible and economically viable biorefinery processes.
