“…The functional differences between the cytochrome c-and iron-sulfur-based transmembrane subunits, and the interactions of these subunits with different membrane quinol pools (ubiquinol and menaquinol), may be important to the putative functional difference between NAP-a and NAP-b in Shewanella. In aerobic cultures of Shewanella, ubiquinols (ubiquinol 7 and 8) are present in higher concentrations than menaquinols (menaquinol 7 and methylmenaquinol 7) (Akagawa-Matsushita et al, 1992;Nishijima et al, 1997;Venkateswaran et al, 1999), which accords with the classification of ubiquinol as the 'aerobic' quinol (Soballe & Poole, 1999). Anaerobic cultures of S. oneidensis MR-1 produce four to fivefold more menaquinols than ubiquinols (Myers & Myers, 2000).…”

In the bacterial periplasm, the reduction of nitrate to nitrite is catalysed by a periplasmic nitrate reductase (NAP) system, which is a species-dependent assembly of protein subunits encoded by the nap operon. The reduction of nitrate catalysed by NAP takes place in the 90 kDa NapA subunit, which contains a Mo-bis-molybdopterin guanine dinucleotide cofactor and one [4Fe"4S] iron-sulfur cluster. A review of the nap operons in the genomes of 19 strains of Shewanella shows that most genomes contain two nap operons. This is an unusual feature of this genus. The two NAP isoforms each comprise three isoform-specific subunits -NapA, a di-haem cytochrome NapB, and a maturation chaperone NapD -but have different membrane-intrinsic subunits, and have been named NAP-a (NapEDABC) and NAP-b (NapDAGHB). Sixteen Shewanella genomes encode both NAP-a and NAP-b. The genome of the vigorous denitrifier Shewanella denitrificans OS217 encodes only NAP-a and the genome of the respiratory nitrate ammonifier Shewanella oneidensis MR-1 encodes only NAP-b. This raises the possibility that NAP-a and NAP-b are associated with physiologically distinct processes in the environmentally adaptable genus Shewanella. IntroductionSpecies of the genus Shewanella are defined as pink-or salmon-coloured, Gram-negative, rod-shaped, facultative anaerobic bacteria with a single polar flagellum that are oxidase-and catalase-positive and can reduce trimethylamine N-oxide (TMAO) and nitrate (Venkateswaran et al., 1999). Almost all Shewanella species to date have been discovered in extreme aquatic or terrestrial environments, including deep-sea trench sediments, Antarctic ice cores, and sites contaminated with toxic compounds, including arsenic, remnants of military explosives or crude oil (Konstantinidis et al., 2009;Zhao et al., 2005Zhao et al., , 2006. Most Shewanella species are classifiable into one or more selected extremophilic subgroups: halophiles, psychrophiles or barophiles (Fredrickson et al., 2008;Hau & Gralnick, 2007;Pakchung et al., 2006). Most recently, Shewanella vesiculosa sp. nov. and Shewanella marina sp. nov. have been characterized from marine environments (Bozal et al., 2009;Park et al., 2009) and contribute to the 51 species of Shewanella identified at the time of writing (http://www.bacterio.cict.fr/). Some Shewanella species, most notably Shewanella oneidensis MR-1, can grow via the reduction of metal oxides -including Fe(III), Mn(IV), Cr(VI), U(VI), Tc(VI), V(V) -thiosulfate, elemental sulfur and arsenate (Burns & DiChristina, 2009;Carpentier et al., 2005;Konstantinidis et al., 2009;Malasarn et al., 2008;Murphy & Saltikov, 2007;Nealson & Saffarini, 1994;Nealson & Little, 1997). The respiratory versatility of Shewanella species has significant implications in bioremediation and in the assembly of microbial fuel cells (Fredrickson et al., 2008;Hou et al., 2009;Kim et al., 2002;Tiedje, 2002). Interest in the ecology and physiology of Shewanella at the genetic level is reflected by the 19 genome sequencing projects completed by the US ...

“…The genus Shewanella is composed of four species, and only one of these species, Shewanella hanedai, is bioluminescent. Compared to species of the genera Alteromonas, Pseudomonas, and Deleya, S. hanedai and Shewanella putrefaciens have unique quinone compositions, and these organisms possess menaquniones that are not present in Alteromonas species (1). Further confirmation that these Shewanella species form an independent clade that can be recognized as a genus came from 16s rRNA sequence analysis (4).…”

Thirty-four strains of nonfermentative, respiratory, luminous bacteria were isolated from samples of squid ink and seawater from depths of 200 to 300 m in the Alboran Sea. Although these strains had a few properties similar to properties of Shewanella (Alteromonas) hanedui, they did not cluster phenotypically with any previously described bacterium. The nucleotide sequence of a 740-bp segment of l d was not homologous with other known l d sequences but clustered with the 2 4 sequences of Shewanella hanedai, fibrio logei, fibriofischeri, and Photobacterium species. The 16s RNA gene from two strains was sequenced and was found to be most closely related to the S. hunedai 16s RNA gene. Based on the differences observed, we describe the new isolates as members of a new species, Shewanella woodyi sp. nov. Strain ATCC 51908 (= MS32) is the type strain of this new species.The first isolates of exclusively respiratory (nonfermentative) marine luminous bacteria were assigned to Alteromonas hanedai (2, 5a) and later were reassigned to the genus Shewanella (5b, 9). The genus Shewanella is composed of four species, and only one of these species, Shewanella hanedai, is bioluminescent. Compared to species of the genera Alteromonas, Pseudomonas, and Deleya, S. hanedai and Shewanella putrefaciens have unique quinone compositions, and these organisms possess menaquniones that are not present in Alteromonas species (1). Further confirmation that these Shewanella species form an independent clade that can be recognized as a genus came from 16s rRNA sequence analysis (4).Water samples and squid ink samples from intermediatedepth dives of the submersible Johnson Sea Link contained luminous bacteria that were found to be unable to ferment sugars but could grow anaerobically with nitrate or nitrite as a terminal electron acceptor. Because these organisms did not seem to be similar to S. hanedai, we performed a more complete phenotypic characterization along with a hybridization and sequence analysis of a 740-bp section of the luxA gene, and we also sequenced the 16s RNA gene from two strains. We designated these new isolates Shewanella woodyi sp. nov. The species name is in honor of J. Woodland Hastings, known to most as Woody, an American biologist who, among other things, has made numerous and valuable contributions to our understanding of the biochemistry and function of bacterial bioluminescence. MATERIALS AND METHODSAll of the strains analyzed in this study (Table 1) Our previous experience with luminous marine bacteria indicated that this medium was suitable for most luminous marine bacteria; however, S. woodyi grew but did not produce luminescence in GMA broth (this was later shown to be due to a salt requirement for luminescence). We also found that the strains whose designations begin with MS (MS strains) did not utilize glycerol. Consequently, the medium used for these strains was changed to Shewanella marine agar (SMA) containing (per liter) 5 g of Bacto Peptone (Difco), 1 g of Bacto Yeast Extract (Difco), 15 g of Bacto Ag...

Isoprenoid quinones were extracted from lyophilized cells and analysed as described by Akagawa-Matsushita et al (1992). Isoprenoid quinone composition was characterized by HPLC (Shimadzu instruments) using a reversed-phase type Zorbax ODS column (25064?6 mm) and acetonitrile/2-propanol (65 : 35, v/v) as a mobile phase at a flow rate of 0?5 ml min 21 .…”

Six novel gliding, heterotrophic, Gram-negative, yellow-pigmented, aerobic, oxidase- and catalase-positive bacteria were isolated from the green alga Ulva fenestrata, sea water and a bottom sediment sample collected in the Gulf of Peter the Great, Sea of Japan. 16S rRNA gene sequence analysis revealed that the strains studied were members of the family Flavobacteriaceae. On the basis of their phenotypic, chemotaxonomic, genotypic and phylogenetic characteristics, the novel bacteria have been assigned to the new genus Maribacter gen. nov., as Maribacter sedimenticola sp. nov., Maribacter orientalis sp. nov., Maribacter aquivivus sp. nov. and Maribacter ulvicola sp. nov., with the type strains KMM 3903T (=KCTC 12966T=CCUG 47098T), KMM 3947T (=KCTC 12967T=CCUG 48008T), KMM 3949T (=KCTC 12968T=CCUG 48009T) and KMM 3951T (=KCTC 12969T=DSM 15366T), respectively.
