An Analysis of Collaboration Networks in Bioenergy: Using the ‘Bioen Program’ to Evaluate Sugarcane Ethanol Biomass (FULL-TEXT)

This paper analyzes the network of scientific collaboration in sugarcane biomass. The impact of the FAPESP research program on bioenergy (BIOEN) is also analyzed, with a focus on the division of biomass and its
subareas. Using detailed information from scientific articles in the subareas of Enzymatic hydrolysis, molecular markers, delignification, genotypes, enzymatic conversion, gene expression, nitrogen and photosynthesis, an evaluation of the international insertion of research and collaboration networks of Brazilian researchers is carried out. The methodologyconsists of the formation of clusters of publications indexed on the ISI Web of Science database. The selection of publications is guided by search queries based on keywords related to the subareas of biomass division. The software programs VantagePoint and Pajek are used to support the analysis of the information. The principle objective of the study is to identify the global incorporation of efforts to generate knowledge in sugarcane biomass carried out by BIOEN. Through an analysis of the indicators, it was possible to identify a number of factors related to scientific collaboration in the area of biomass, such as geographic distance, area with the greatest contribution in a determined field of study, and the dynamics of scientific collaboration between countries. An analysis of the biomass division of BIOEN, from a global perspective, showed little cooperation between Latin American countries. The results illustrate that Brazil generates the greatest amount of scientific knowledge regarding sugarcane biomass. However, when the subareas are analyzed separately, scientific publications from the US and China are also dominant

Xylose utilization in ethanol production: a patent landscape

Bioethanol is considered as one of the best alternatives to fossil fuels as unwanted biomass is converted into fuel ethanol. As there is increasing demand for fuel ethanol, researchers have started looking for some better ways to produce ethanol. In light of the present scenario, we have attempted to develop a global patent landscape view of xylose utilization in ethanol production. Our country-specific patent analysis has revealed that most of the research on xylose-utilizing ethanol production is carried out in the USA followed by China and Sweden. Moreover, it has been found that more patent applications/grants have been claimed for processes, followed by recombinant strains. Patent publication trends for genes and enzymes have shown that most of the research is focused on the xylA gene and xylulokinase. Assignee patenting trends suggest that Du Pont is the major player in xylose-utilizing ethanol production research. Additionally, analysis based on micro-organisms used in xylose-utilizing ethanol production revealed that most of the research has been performed using Saccharomyces cerevisiae to enhance the ethanol yields.
