Abstract

Arthrospira is an economically important cyanobacterium that contains many useful products, including proteins, vitamins, lipids, and pigments, and it is distributed in several alkaline soda lakes. Arthrospira platensis NIES-46 produces large amounts of hydrogen. In this study, we sequenced the NIES-46 draft genome and performed comparative analyses among Arthrospira species to elucidate the genomic background of this strain. The genome consists of 5.7 Mbp with a GC% of 44.5% and encodes 5,008 proteins. Our phylogenetic analysis using multiple orthologous proteins shows that Arthrospira is divided into two clades and that NIES-46 is closely related to A. platensis NIES-39. The genome structure and protein functions are highly conserved between A. platensis NIES-39 and NIES-46, suggesting that these two strains have recently diverged. Genes involved in hydrogen production are well-conserved among Arthrospira species, indicating conserved abilities to produce hydrogen.
