Mycobacterium vanbaalenii is a rapidly growingmycobacterium that can usepolycyclic aromatic hydrocarbons. It was first isolated from petroleum-contaminated estuarine sediments and has been shown by 16S rRNA gene sequencing to be closely related toMycobacterium aurum andMycobacterium vaccae.M. vanbaalenii has potential use in thebioremediation ofpolycyclic aromatic hydrocarbon contaminated environmental sites.Etymology: vanbaalenii of Van Baalen, in memory of Dr Chase Van Baalen, late Professor at The University of Texas Marine Science Institute, Port Aransas Marine Laboratory, Port Aransas, TX, USA.
