The DSMZ 20288 chromosome was analysed by pulsed-field gel electrophoresis, enabling the construction of a physical and genetic map. A total of 21 recognition sites of the restriction enzymes I, I-I, I and I were mapped on the chromosome, which was found to be circular with an estimated size of 2026 kb. This is believed to constitute the first study into the genomic organization of a strain of this genus, addressing the localization of important chromosomal regions such as and . A total of 23 genetic markers were mapped, including eight operons that were precisely assigned in 37 % of the chromosome. The transcription direction of loci was determined and three different clusters were recognized regarding the presence/absence of tRNA genes in ITS regions.
