In this survey, a bibliometric analysis of the global scientific production on enzyme immobilization researches was developed using Web of Science© database. The time-span comprised the period from 1991 to 2017. A total of 9636 documents related to the subject were retrieved and analyzed according to seven main aspects: publication years, journals, countries, authors, organizations, keywords, and Web of Science categories. The results indicated that the countries with the highest number of publications were China and the United States. The most expressive international collaborative networks were evidenced between Brazil and Spain and between the USA and China. Additionally, the Spanish researchers were the ones that contributed most to this domain, while the Consejo Superior de Investigaciones Cientificas and the Chinese Academy of Sciences were the most emblematic organizations. Finally, the analysis of keywords revealed that biosensor, lipase and glucose oxidase were the most cited terms among all publications, and also indicated the existence of a possible knowledge gap involving the terms Escherichia coli, Candida rugosa lipase and cytochrome-c in the context of enzyme immobilization. This study was efficient to evaluate the trends of the body of literature on enzyme immobilization research, subsidizing future decision-making in this field of science.

A bibliometric analysis was performed to evaluate the global scientific production on ecological restoration from the period of 1997 to 2017. This analysis was based on online database of Science Citation Index Expanded – Web of Science© and a total of 3297 publications was retrieved. The analysis comprised seven main aspects: (1) publication activity, (2) Web of Science categories, (3) journals, (4) countries, (5) authors, (6) organizations and (7) keywords. The results indicated that the annual publications on ecological restoration study have recently increased. The USA play an important role as they have published highly in this field and have been the most frequent partner in international collaborations. American researchers have accumulated most of the publications. The Chinese Academy of Science is the emblematic organization, with 363 published papers. The Restoration Ecology and Ecological Engineering are the two most used journals to disseminate results. The major related research areas are “Environmental Science Ecology”, “Forestry” and “Biodiversity Conservation”. Studies about “restoration”, “pinus ponderosa”, “climate change”, “biodiversity” and “ecosystem services” have become the main subject of research along the years. Analyses of keywords suggested that there is a relatively lack of information about “soil” and “tropical ecosystems” among the analyzed studies. Overall, this framework proved to be effective to evaluate the recent research trends and to contribute with researchers and governments on management and decision-making on science.
