Scientific articles come mainly from China, Italy, and the United States. The most productive journals, authors, institutions, and countries are Bioresource Technology, Irini Angelidaki, Danmarks Tekniske Universitet, and China. All this research is of supreme importance for the development of this line of research at the Universidad del Atlántico, where research projects are currently being developed that will contribute to the strengthening of the national and international scientific community
