The complete alk sequences of Rhodococcus erythropolis from Lake Baikal

چکیده
BACKGROUND Rhodococci are bacteria able to degrade a wide range of hydrocarbons, including the alkanes present in crude oil, due to alk genes in their genomes. FINDINGS Genome sequencing of DNA from Rhodococcus erythropolis strain 4 (obtained from a deep-water bitumen mound) revealed four alk genes, and the predicted amino acid sequences coded by these genes were highly conserved, having sections up to 11 amino acid residues. CONCLUSIONS Obtained four genes from Rhodococcus erythropolis were similar to corresponding genes from other bacteria collected from other environments, including marine sources. This indicated a large-scale horizontal alk gene transfer between bacteria from different subgenera.

The complete nucleotide sequence of the 5936 bp cryptic plasmid pFAJ2600 from Rhodococcus erythropolis NI86/21 was determined. Based on the characteristics of its putative replication genes, repA and repB, pFAJ2600 was assigned to the family of pAL5000-related small replicons identified in Mycobacterium (pAL5000), Corynebacterium (pXZ10142), Brevibacterium (pRBL1), Bifidobacterium (pMB1) and Ne...
