Oil Bioremediation in the Marine Environment of Antarctica: A Review and Bibliometric Keyword Cluster Analysis

Bioremediation of hydrocarbons has received much attention in recent decades, particularly relating to fuel and other oils. While great relevance globally, there recently been increasing interest hydrocarbon bioremediation the marine environments Antarctica. To provide an objective assessment research this field we used VOSviewer software analyze publication data obtained from ScienceDirect database covering period 1970 present, but with a primary focus on years 2000–2020. A bibliometric analysis allowed identification co-occurrence keywords. There was trend over time for publications oil maritime Antarctica, including both studies metabolic pathways degradation. Studies anaerobic degradation remain under-represented compared those aerobic Emerging keywords included bioprospecting, metagenomic, bioindicator, giving insight into changing foci, such as microbial diversity. The study genomes using metagenomic approaches or whole genome is rapidly likely drive emerging fields future, rapid expansion bioprospecting diverse biotechnology.
