Abstract
Oil drilling and increased shipping in Arctic and subarctic marine regions risk environmental spills and catastrophic effects on marine life and coastal communities. Murphy et al. (e00800-21) conducted spill simulations in laboratory mesocosms that revealed the capacity of cold-adapted microbes from the Labrador Sea to remediate diesel and crude oil contamination. Genomic sequencing revealed unexpected potential for hydrocarbon bioremediation in lineages of bacteria including Paraperlucidibaca, Cycloclasticus, and Zhongshania. Biostimulation of these microbes enhanced their remediation capacity. This strategy shows promise for the environmental restoration of cold ecosystems impacted by oil spills.
