Carotenoids are ubiquitous and essential pigments in photosynthesis. They absorb in the
blue-green region of the solar spectrum and transfer the absorbed energy to (bacterio-) …

Ongoing work has led to the identification of most of the biochemical steps in carotenoid
biosynthesis in chlorophototrophic bacteria. In carotenogenesis, a relatively small number of …

The increasing production of synthetic and natural poly (cis-1, 4-isoprene) rubber leads to
huge challenges in waste management. Only a few bacteria are known to degrade rubber …

The biosynthesis of the major carotenoid spirilloxanthin by the purple nonsulfur bacterium
Rhodospirillum rubrum is thought to occur via a linear pathway proceeding through …

Purple bacteria including aerobic photosynthetic bacteria belong to the Proteobacteria, and
75 genera including around 160 species have been described. These bacteria produce …

A brown-coloured bacterium was isolated from photoheterotrophic (benzoate) enrichments
of flooded paddy soil from Andhra Pradesh, India. On the basis of 16S rRNA gene sequence …

Photosynthesis genes and operons of aerobic anoxygenic photosynthetic (AAP) bacteria
have been examined in a variety of marine habitats, but genomic information about …

We reported previously that the Rhodococcus erythropolis strain AN12 synthesizes the
monocyclic carotenoids 4-keto γ-carotene and γ-carotene. We also identified a novel …

Aerobic photosynthetic bacteria possess the unusual characteristic of producing different
classes of carotenoids. In this study, we demonstrate the presence of two distinct crt gene …

Okenone is a unique ketocarotenoid found in many purple sulfur bacteria; it is important
because of its unique light absorption and photoprotection properties. Okenane, a …
