ASTAXANTHIN-PRODUCING BACTERIUM, BACTERIUM CULTURE PRODUCT, ASTAXANTHIN-CONTAINING COMPOSITION, AND METHOD FOR PRODUCTION OF ASTAXANTHIN

摘要

A bacterium belonging to the genus Erythrobacter which can produce astaxanthin accounting for 35% by mass or more of the produced composition; a bacterium of Erythrobacter JPCC M sp. whose 16S rDNA sequence consists of the nucleotide sequence represented by SEQ NO:1 or a nucleotide sequence having a 96% or higher homology with the nucleotide sequence represented by SEQ ID NO:1; a bacterial culture product yielded by culturing the bacterium; an astaxanthin-containing composition collected from the bacterium; and a method for producing astaxanthin which comprises the step of culturing a bacterium belonging to the genus Erythrobacter, wherein the bacterium has an astaxanthin productivity capable of producing astaxanthin accounting for 35% by mass or more of the all produced pigments.
