Bibliometric Analysis of Research on Bioethanol Production from Algaroba (Prosopis Juliflora)

This study conducts a bibliometric analysis of the last decade, focusing on the production of 2G ethanol from Algaroba as a biomass source. Using the Web of Science database, four main areas were categorized: Product (second-generation ethanol, bagasse, ethanol production, bioethanol, ethanol), Process (biomass treatment, fermentation, distillation, hydrolysis, saccharification, adsorption), Equipment (bioreactors, fermenters), and Raw Material (Algaroba, Prosopis juliflora). The combination of Product and Raw Material revealed significant clusters, highlighting 40 prominent articles in the areas of biotechnology, renewable energy, and biological resource technology. The predominant process involves steps such as drying, size reduction, pretreatment, hydrolysis, detoxification, fermentation, and bioethanol separation. The choice of microorganisms, especially S. cerevisiae and Z. mobilis in the last three years, reflects the trend towards thermotolerant yeasts for increased saccharification and fermentation efficiency. Co-culturing for the fermentation of sugar mixtures emerges as a promising alternative. This study contributes to understanding the research dynamics in second-generation ethanol production from Algaroba, providing crucial insights to advance toward a more sustainable energy matrix.
