Rubrobacter xylanophilus is a thermophilic species of bacteria. It is slightly halotolerant, short rod- and coccus-shaped and gram-positive, with type strain PRD-1T. It is the only known true radiation resistant thermophile. It can degrade xylan and hemicellulose.[1] The first strain of the genus Rubrobacter was isolated from gamma-irradiated hot spring water samples by Yoshinaka. This organism was found to be extremely gamma-radiation resistant, with a higher shoulder dose than the canonical radiation resistant species of the genus Deinococcus. The organism stained Gram-positive and was slightly thermophilic with an optimum growth temperature of about 60 °C.[2].Genome sequencing of Rubrobacter xylanophilus has revealed numerous genes involved in DNA repair and oxidative stress protection, which are thought to contribute to its extreme resistance to radiation.[3] The species produces a thermostable D-amino acid oxidase that remains active at 65 °C.[4]
