Zeaxanthin, aC40xanthophyll carotenoid,has potential biological applications in nutrition and human health. In this study we characterized carotenoid composition in 5 taxonomically related marine bacterial isolates from the genus Muricauda. The pigment was characterized using high performance liquid chromatography (HPLC)and mass spectrometry, which confirmed the presence of all-trans-zeaxanthin. Muricauda strains produced zeaxanthin as a predominant carotenoid. M. flavescens JCM 11812Tproduced highest yield (4.4 ± 0.2 mg L-1) when cultured on marine broth at 32 °C for 72 h.This is the first reporton the presence of zeaxanthinamong the majority of species from the genus Muricauda.
