Strains were identified using phenotypic characteristics and the listed name corresponds to that used in the original publication. It is important to note that the correct name of the organism may have changed since the original date of publication.
Kanner and Bartha (1979) suggested based on phenotypic characteristics that this organism was mostly likely a Rhodococcus rhodochrous.
de Bont et al. (1980) identified strain A1 as Rhodococcus rhodochrous using DNA–DNA hybridization.
Although originally isolated and cultivated under aerobic conditions Germon and Knowles (1988) showed that strain E5 can degrade acetylene under anaerobic conditions.
Isolation of and metabolism of propane by this organism was reported in Woods and Murrell (1989).
