Advancement of research involving Aspergillus niger and sugarcane bagasse as a source of carbon for the production of cellulases: A bibliometric analysis

摘要

A variety of studies have been realized with the objective of producing celulases with low cost to be used in the production of second generation alcohol (2G) from lignocellulosic residues. Among them, the use of sugarcane bagasse as carbon source for the growth of microorganisms is highlighted. Based on this, this article aimed to carry out a bibliometric review on the use of Aspergillus niger using sugarcane bagasse as a carbon source, aiming the production of cellulase, through the study of scientific and technological advances on the themes. To perform the review, we used the Web of Science database, inserting four keywords: "Aspergillus niger", "cellulase", "cane" and "submerged" between the years of 1945 and 2018. From this search, was possible to identify the most important authors, periodicals and research groups in this subject. It was identified an increase in the number of publications over the years by several countries, showing interest in the production of lower cost cellulases for 2G alcohol generation. Brazil was the country with the largest number of publications on the subject, due to the great capacity of planting sugarcane and production of alcohol. By analyzing the correlation networks of the authors it was verified the existence of a relation of the research groups in Brazil, between the cities of Campinas, S?￡o Paulo and Curitiba and another association in Denmark, between the cities of Lyngby and Copenhagen.
