“…In contrast, various reports showed that these organisms are abundant in eutrophic as well as in oligotrophic environments (Jiao et al, 2007;Koblížek et al, 2006;Yutin et al, 2007). Other authors suggested that nutrient concentrations (Mašín et al, 2008), attachment to particles Waidner and Kirchman, 2007) or light intensity (Koblížek et al, 2003;Shiba, 1991) may influence AAP bacterial abundance.…”

Abstract. Aerobic anoxygenic phototrophic (AAP) bacteria are photoheterotrophic prokaryotes able to use both light and organic substrates for energy production. They are widely distributed in coastal and oceanic environments and may contribute significantly to the carbon cycle in the upper ocean. To better understand questions regarding links between the ecology of these photoheterotrophic bacteria and the trophic status of water masses, we examined their horizontal and vertical distribution and the effects of nutrient additions on their growth along an oligotrophic gradient in the Mediterranean Sea. Concentrations of bacteriochlorophyll-a (BChl-a) and AAP bacterial abundance decreased from the western to the eastern basin of the Mediterranean Sea and were linked with concentrations of chlorophyll-a, nutrient and dissolved organic carbon. Inorganic nutrient and glucose additions to surface seawater samples along the oligotrophic gradient revealed that AAP bacteria were nitrogen-and carbon-limited in the ultraoligotrophic eastern basin. The intensity of the Correspondence to: D. Lamy (lamyd2@univie.ac.at) AAP bacterial growth response generally differed from that of the total bacterial growth response. BChl-a quota of AAP bacterial communities was significantly higher in the eastern basin than in the western basin, suggesting that reliance on phototrophy varied along the oligotrophic gradient and that nutrient and/or carbon limitation favors BChl-a synthesis.

“…The classification of Erythrobacter as a genus separate from Erythromicrobium and Porphyrobacter is warranted by only small phenotypic differences (Shiba, 1991;Fuerst et al, 1993;Yurkov et al, 1994). However, the separation of the cluster that comprises Erythrobacter from the cluster that comprises the genera Erythromicrobium and Porphyrobacter has been supported by a high bootstrap resampling value (Denner et al, 2002).…”

“…The genus Erythrobacter is characterized chemotaxonomically by having C 18 : 1 as the major fatty acid and by a DNA G+C content of 60-67 mol% (Shiba & Simidu, 1982;Fuerst et al, 1993;Yurkov et al, 1994). However, Shiba (1991) reported that the type strain of E. longus has a DNA G+C content of 57?4 mol%.…”

Two Gram-negative, motile, non-spore-forming, yellow-pigmented and slightly halophilic strains (SW-46 T and SW-52) were isolated from sea water of the East Sea, Korea, and subjected to a polyphasic taxonomic study. Strains SW-46 T and SW-52 were characterized chemotaxonomically by having ubiquinone-10 (Q-10) as the predominant respiratory lipoquinone and C 18 : 1 v7c as the major fatty acid. Their DNA G+C content was 64?0-64?1 mol%. Strains SW-46 T and SW-52 showed 1 bp difference in their 16S rDNA sequences and a mean DNA-DNA relatedness level of 94?4 %. Phylogenetic analysis based on 16S rDNA sequences showed that strains SW-46 T and SW-52 fall within the a-subclass of the Proteobacteria and form a coherent cluster with Erythrobacter longus, Erythrobacter litoralis and Erythrobacter citreus. Levels of 16S rDNA similarity between strains SW-46 T and SW-52 and the type strains of these three Erythrobacter species were 96?5-97?9 %. Levels of DNA-DNA relatedness between strains SW-46 T and SW-52 and the type strains of E. longus, E. litoralis and E. citreus were 3?6-14?7 %. Therefore, on the basis of phenotypic properties, phylogeny and genomic data, strains SW-46 T and SW-52 should be placed in the genus Erythrobacter as a novel species, for which the name Erythrobacter flavus sp. nov. is proposed. The type strain is SW-46 T (=KCCM 41642 T =JCM 11808 T ).
