Background Rhodobacter sphaeroides KD131 (KCTC12085) is a halophilic, purple nonsulfur photosynthetic bacterium that produces high levels of biohydrogen H(2). The strain, KD131, was originally isolated from sea mud off the coast of DaeBu Island, South Korea. Like the other three sequenced R.sphaeroides strains (2.4.1, ATCC 17025 and ATCC 17029) it has a large 3.1 Mb chromosome and a small 1.3 Mb chromosome in addition to 2 smaller plasmids. Comparative optical mapping studies have shown that in terms of size and physical map structure, the large chromosome in these strains is relatively stable, whereas the smaller chromosomes are much more variable.
