Carotenoidsrsquo; Production from Halophilic Bacteria
Carotenoids have received considerable attention due to their interesting industrial applications and, more importantly, their potential beneficial effects on human health. Halophiles comprise a heterogeneous group of microorganisms that need salts for optimal growth. The pigments produced by these halophilic organisms comprise phytoene, beta;-carotene, lycopene, derivatives of bacterioruberin, and salinixanthin. Here, we describe the procedure to obtain salinixanthin from the extremely halophilic bacterium Salinibacter ruber. Additionally, we describe the expression of the beta;-carotene biosynthetic genes crtE, crtY, crtI, and crtB from Pantoea agglomerans in the moderately halophilic bacterium Halomonas elongata obtaining a strain able to produce practically pure beta;-carotene. Thus...
