<p> There are currently 58 different Rhodococcus species (reference list periodically updated at http://www.bacterio.net/rhodococcus.html) and based on 16S rRNA data (McMinn et al., 2000) they are classified into three main subclades: R. erythropolis, R. equi and R. rhodochrous. Of the R. erythropolis subclade, the three most characterised industrial species are R. erythropolis, R. opacus, and R. jostii (Goodfellow et al., 2012). R. erythropolis was the first characterised bacteria in this subclade while R. jostii was the first to have its genome sequenced (McLeod et al., 2006). R. opacus has the unique ability of accumulating up to 40% of its dry cell mass as triacylglycerols (Kurosawa et al., 2010). All three species catabolise a wide range of oligosaccharides and organic compounds, but R. erythropolis has two industrial advantages of tolerating a wider range of temperatures and possessing a significantly smaller genome, corresponding to faster growth rate. However, the larger genomes of R. jostii and R. opacus gives them the ability to metabolise a wider range of organic substances. | <p> There are currently 58 different Rhodococcus species (reference list periodically updated at http://www.bacterio.net/rhodococcus.html) and based on 16S rRNA data (McMinn et al., 2000) they are classified into three main subclades: R. erythropolis, R. equi and R. rhodochrous.
