Identification of a novel monocyclic carotenoid and prediction of its biosynthetic genes in Algoriphagus sp. oki45.

ABSTRACT: Bacteria belonging to the genus Algoriphagus have been isolated from various sources, such as Antarctic sea ice, seawater, and sediment, and some strains are known to produce orange to red pigments. However, the pigment composition and biosynthetic genes have not been fully elucidated. A new red-pigmented Algoriphagus sp. strain, oki45, was isolated from the surface of seaweed collected from Senaga-Jima Island, Okinawa, Japan. Genome comparison revealed oki45's average nucleotide identity of less than 95% to its closely related species, Algoriphagus confluentis NBRC 111222 ^T and Algoriphagus taiwanensis JCM 19755 ^T. Comprehensive chemical analyses of oki45's pigments, including ¹H and ¹³C nuclear magnetic resonance and circular dichroism spectros
