چکیده

Zeaxanthin, a C40xanthophyll 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 11812(T) produced highest yield (4.4 +/- 0.2 mg L(-1)) when cultured on marine broth at 32 degrees C for 72 h. This is the first report on the presence of zeaxanthin among the majority of species from the genus Muricauda.

Complete genome sequence of the facultatively anaerobic, appendaged bacterium Muricauda ruestringensis type strain (B1T)

Muricauda ruestringensis Bruns et al. 2001 is the type species of the genus Muricauda, which belongs to the family Flavobacteriaceae in the phylum Bacteroidetes. The species is of interest because of its isolated position in the genomically unexplored genus Muricauda, which is located in a part of the tree of life containing not many organisms with sequenced genomes. The genome, which consists ...

Carotenoid biosynthesis changes in five red pepper (Capsicum annuum L.) cultivars during ripening. Cultivar selection for breeding.

Changes in the biosynthesis of individual carotenoid pigments have been investigated during fruit ripening of five cultivars of red pepper (Capsicum annuum L.): Mana, Numex, Belrubi, Delfin, and Negral (a chlorophyll-retaining mutant when ripe). The study was carried out throughout the ripening process, and with special emphasis on the ripe stage, to discover possible differences between cultiv...

Introduction of new carotenoids into the bacterial photosynthetic apparatus by combining the carotenoid biosynthetic pathways of Erwinia herbicola and Rhodobacter sphaeroides.

Carotenoids have two major functions in bacterial photosynthesis, photoprotection and accessory light harvesting. The genes encoding many carotenoid biosynthetic pathways have now been mapped and cloned in several different species, and the availability of cloned genes which encode the biosynthesis of carotenoids not found in the photosynthetic genus Rhodobacter opens up the possibility of intr...

Cloning and characterization of the zeaxanthin glucosyltransferase gene (crtX) from the astaxanthin-producing marine bacterium, Paracoccus haeundaensis.

Zeaxanthin glucosyltransferase (CrtX) mediates the formation of zeaxanthin to zeaxanthin diglucoside. Here, we report cloning of the crtX gene responsible for zeaxanthin diglucoside biosynthesis from Paracoccus haeundaensis and the production of the corresponding carotenoids in transformed cells carrying this gene. An expression plasmid containing the crtX gene (pSTCRT-X) was constructed, and E...

Recent Studies of Carotenoid Biosynthesis

The effects of nicotine on carotenoid biosynthesis have been investigated in a non-photosynthetic Flavobacterium strain 0147, and in two photosynthetic bacteria, Rhodopseudomonas spheroides and Rhodomicrobium vanrtielii. In Flavobacterium, nicotine inhibits the synthesis of the nOrmal main carotenoid, zeaxanthin, and causes an accumulation of lycopene at high nicotine concentration, and rubixan...
