An integrated metagenomic and metabolite profiling study of hydrocarbon biodegradation and corrosion in navy ships

Abstract Naval vessels regularly mix fuel and seawater as ballast, a practice that might exacerbate fuel biodegradation and metal biocorrosion. To investigate, a metagenomic characterization and metabolite profiling of ballast from U.S. Navy vessels with residence times of 1-, ~20-, and 31 weeks was...
