Outline of Final Research Achievements

This study determined the complete genome sequence of Aurantimicrobium minutum, a free-living planktonic ultramicrobacterium isolated from river water in western Japan. This strain has an extremely small, streamlined genome of approximately 1.6 Mb. Such a reduction in genome size may be associated with lowering resource costs. Additionally, genomic annotation of this strain suggests that it undergoes rhodopsin-based photometabolism.
