“…C). Presence of 2′‐isopentenylsaproxanthin was reported earlier in the marine flavobacterium Jejuia pallidilutea , which was isolated in Japan and South Korea (Lee et al ., ; Takatani et al ., ). Taking the observed auto‐oxidation into account, it is likely that 2′‐Isopentenylsaproxanthin is also the actual compound produced by R .…”

Planctomycetes are ubiquitous and environmentally important Gram-negative aquatic bacteria with key roles in global carbon and nitrogen cycles. Many planctomycetal species have a pink or orange colour and have been suggested to produce carotenoids. Potential applications as food colorants or antioxidants have been proposed. Hitherto, the planctomycetal metabolism is largely unexplored and the strain pigmentation has not been explored. For a holistic view of the complex planctomycetal physiology, we analysed carotenoid profiles of the pink-pigmented strain Rhodopirellula rubra LF2 T and of the orange strain Rubinisphaera brasiliensis Gr7. During LC-MS/MS analysis of culture extracts, we could identify three saproxanthin-type carotenoids including a rare C 45 carotenoid. These compounds, saproxanthin, dehydroflexixanthin and 2 0isopentenyldehydrosaproxanthin, derive from the common carotenoid precursor lycopene and are characterized by related end groups, namely a 3-hydroxylated β-carotene-like cyclohexene ring as one end group and simple hydration on the other end of the molecule. Based on the observed molecule structure we present putative pathways for their biosynthesis. Results support Planctomycetes as a promising, yet mostly untapped source of carotenoids.

“…The percentage of the carotenoids was determined with UV-VIS diode array spectrophotometer, separated by reversed phase HPLC beyond thin layer chromatography (TLC) (Kim et al, 2007). A study with the new carotenogenic bacteria Jejuia pallidilutea strain 11shimoA1 was performed, with Fast Atom Bombardment Mass Spectroscopy (FAB-MS), nuclear magnetic resonance (NMR), circular dichroism (CD), DNA molecular analysis and the quantitative analysis of carotenoids was subjected to HPLC (Takatani et al, 2014).…”

Carotenoids are natural pigments that can be synthesized by various microorganisms, including bacteria, yeasts, filamentous fungi and microalgae. These pigments comprise around 700 different structures with peculiar colors and biological properties that are beneficial to health. Advantages of biotechnological production of carotenoids include the ability of microorganisms to use low cost substrates, the optimized control of cultivation, minimized production time and the natural origin of the synthesized pigments. Techniques for separation and purification of carotenoids are well established at laboratory scale, however the development of processes that can be economically scaled-up is essential for industrial production.

“…One of the genera, Jejuia , was proposed in 2009 for nonmotile, yellow, nondiffusible pigment producers in seawater and consists of a single species J. pallidilutea ( 2 , 3 ). More recently, Takatani et al ( 4 ) have identified a strain 11shimoA1 isolated from the surface of seaweed that produces not only zeaxanthin but also a new monocyclic carotenoid, 2′-isopentenylsaproxanthin. The amount of 2′-isopentenylsaproxanthin production increased under alkaline conditions ( 4 ).…”

Here, we present the draft genome sequence of a novel carotenoid 2′-isopentenylsaproxanthin producer, Jejuia pallidilutea strain 11shimoA1, isolated from the surface of seaweed in Japan, and the ethyl methanesulfonate-induced pigmentation mutants. This genomic information will help to not only elucidate the 2′-isopentenylsaproxanthin biosynthetic pathway but also understand the evolution of flavobacteria.
