Zeaxanthin, a C₄₀ xanthophyll 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 11812T produced highest yield (4.4 ± 0.2 mg L⁻¹) when cultured on marine broth at 32°C for 72 h. This is the first report on the presence of zeaxanthin among the majority of species from the genus Muricauda.
