Abstract
An orange pigment-producing bacterium, which was identified as Flavobacterium sp., was isolatedfrom a Palauan marine sponge Homaxinella sp. The main orange pigment was extracted from the cultured mycelium and purified by chromatographic method. It was identified as myxol by means of a spectral data. This is the first isolation of myxol, which is known as the aglycone of myxoxanthophyll widely distributed in cyanobacteria.
