Bibliometric analysis of the environmental applications of microalgae: a review
Keywords:
Algae, Biorefinery, BiotechnologyAbstract
During the last decades, microalgae have been pointed out as robust organisms that can be applied efficiently in different productive sectors. Despite the versatility of the biomolecules that are synthesized by microalgae, their scaling is still a limiting factor to make microalgae effective as a competitive and viable industrial product. According to the interest in microalgae, there is a need to identify what research is being developed and to design the most promising areas with microalgae. Therefore, this study aimed to perform bibliometric survey of the environmental applications of microalgae in three scientific databases, Web Science, Scopus and ScienceDirect in the last 10 years using the VOSviewer software. In the three databases, 469 articles with 290 terms were found, being related and divided into 18 clusters. The terms microalgae and biochar obtained the highest occurrences and link strength, with 5.73% and 5.29%; 3.36% and 2.83% respectively. Biochar of the microalgae is considered an emerging innovative product, but it needs to expand its studies to obtain from microalgae biomass. Bibliometric analyses are an important tool for the development of science, by identifying which, how and where scientific research is being carried out. The bibliometric analyses help to project promising areas, identifying other byproducts of biomass microalgae as the viability for the biorefinery.
