Complete genome sequence of Ferrimonas balearica type strain (PATT)
Standards in Genomic Sciences volume 3, pages174–182(2010)
Ferrimonas balearica Rossello-Mora et al. 1996 is the type species of the genus Ferrimonas, which belongs to the family Ferrimonadaceae within the Gammaproteobacteria. The species is a Gram-negative, motile, facultatively anaerobic, non spore-forming bacterium, which is of special interest because it is a chemoorganotroph and has a strictly respiratory metabolism with oxygen, nitrate, Fe(III)-oxyhydroxide, Fe(III)-citrate, MnO2, selenate, selenite and thiosulfate as electron acceptors. This is the first completed genome sequence of a member of the genus Ferrimonas and also the first sequence from a member of the family Ferrimonadaceae. The 4,279,159 bp long genome with its 3,803 protein-coding and 144 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project.
Strain PATT (= DSM 9799 = CCM 4581) is the type strain of the species Ferrimonas balearica, which is the type species of its genus Ferrimonas [1,2]. Currently, there are five species in the genus Ferrimonas . The generic name derives from the Latin word ‘ferrum’ meaning ‘iron’ and the Greek word ‘monas’ meaning ‘unit’, referring to an iron(III)-reducing cell. The species epithet is also derived from the Latin word ‘balearica’ meaning ‘of the Balearic Islands’, referring to the place where the strain was isolated . Ferrimonas is the type genus of the family Ferrimonadaceae and one of two genera in the family Ferrimonadaceae . Strain PATT was described in 1995 by Rossello-Mora et al.  who isolated the strain from the upper few centimeters of marine sediment of the Palma de Mallorca harbor, Spain [1,5]. Here we present a summary classification and a set of features for F. balearica PATT, together with the description of the complete genomic sequencing and annotation.
Classification and features
The 16S rRNA gene sequence of PATT is 99% identical to four culturable strains, which are reported in GenBank . Two strains, A2A-18 (AB193752) and A3B-47-3 (AB193753), were isolated from marine sand . The culturable strain S8-05 (EU620413) was isolated from Palk Bay sediment in Thondi, India and another strain with accession number AY158002 was isolated from Ala Wai Canal sediment in Honolulu, USA. The 16S rRNA gene of strain PATT shares 93.5-97.4% sequence identity with the sequences of the type strains from the other members of the family Ferrimonadaceae . The environmental samples database (env_nt) contains the marine metagenome clone 1096626783183 (96% sequence identity, AACY020355234). The genomic survey sequences database (gss) contains the uncultured bacterium clone BYUP987.b1 (92%, EF996742), isolated from a fecal sample of adult woman who gave birth after 11 months . Altogether, strains belonging to the species F. balearica or the genus Ferrimonas are rather rare in the habitats screened so far (status September 2010).
Figure 1 shows the phylogenetic neighborhood of F. balearica PATT in a 16S rRNA based tree. The sequences of the seven 16S rRNA gene copies in the genome differ from each other by up to five nucleotides, and differ by up to four nucleotides from the previously published sequence (X93021), which contains two ambiguous base calls.
Strain PATT is a Gram-negative, nonspore-forming, facultatively anaerobic bacterium . The cells are straight rods (0.3–0.5 × 1.2–1.5 µm) with rounded ends (Figure 2, Table 1) [1,5] and appear singly, occasionally in pairs or short chains and usually not encapsulated [1,5]. Strain PATT is motile by means of monotrichous flagella (not visible in Figure 2, but 10% of the cells in the original liquid culture were highly motile) . Colonies produce a black iron precipitate when the cells are grown on TSI agar . Although initially isolated using TSI based media this strain grows better on Marine Broth. Colonies are often brown and mucous when the cells are grown under aerobic conditions . Fresh isolates of this species may not form colonies on PYG agar medium, but the colonies are formed after several subcultivations in enrichment medium [1,5]. Resting stages of strain PATT are not known . Cells of the strain undergo autolysis within five days under aerobic conditions [1,5]. Strain PATT does not contain polyhydroxybutyrate (PHB) or other intracellular inclusions . The strain is chemoorganotrophic. Under anaerobic conditions, the reduction of Fe(III)-oxyhydroxide is coupled to the utilization of lactate as the electron donor, which yields magnetite [1,5]. Strain PATT uses oxygen, nitrate, Fe(III)-oxyhydroxide, Fe(III)-citrate, MnO2, selenate, selenite and thiosulfate as electron acceptors [1,5,25]. Strain PATT requires a minimum of 0.5% NaCl for growth, with a range of NaCl tolerance of 0.5%-7.5% . It does not grow at 5°C or 44°C but does grow at 42°C . The pH range for growth is 6–9 . Enzymatic reactions are positive for catalase, oxidase, phenylalanine deaminase, DNAse and lipase (Tween 20 and Tween 80), but negative for amylase, arginine dihydrolase, gelatinase, lysine decarboxylase, Simmons citrate and urease [1,5]. The strain does not hydrolyze starch . The genus Ferrimonas can be distinguished from other strictly respiratory Gram-negative genera of the Gammaproteobacteria based on its ability to reduce Fe(III), denitrification, growth at 42°C, presence of phenylalanine deaminase activity, inability to grow in NaCL-free media, lack of gelatinase, urease and a negative reaction of Simmons citrate test .
The quinone profiles of strain PATT are MK-7 (62.9%), Q-8 (20.4%) and Q-7 (16%) . The presence of both menaquinones and ubiquinones being indicative of the ability of this organism to grow aerobically (with ubiquinones) and anaerobically (with menaquinones). The presence of menaquinones and ubiquinones with different distributions of isoprenoid side chains is a feature also shared by members of the genus Shewanella [26–28] and Paraferrimonas  The major cellular fatty acids of strain PATT, when grown on PYG medium, given in the original species description are C17:1ω8 c (27.5%), iso-C15:0 (14.5%), C17:0 (7.8%), iso-C13:0 (5.8%), C16:1ω7 c (4.7%), C15:0 (4.5%), C13:0 (4.5%), C14:0 (4.2%), C18:1ω9 c (4.0%) and C12:0 3-OH (1.8%), C17:1ω6c (1.6%) and C18:1ω7c (1.2%) . More recent data show a somewhat different fatty acid pattern , with the fatty acids comprising iso-C15:0 (9.8%), C15:0 (1.8%) iso-C16:1ω9c (10.4%) iso-C16: ω7c (5.2%), C16:0 (13.4%) iso-C17:0 (2.1%) C17:1ω8c (12.6%) C17:0 (7.9%) C18:1ω9c (17.6%) C18:1ω7c (4.9%) and C18:0 (3.9%). Hydroxylated fatty acids were not reported. Interestingly the fatty acids reported in a subsequent paper  that are based on the work of Kasuta et al.  omit the iso-C16:1 fatty acids. The fatty acids reported in the original publication  show a number of features also found in members of the genera Shewanella and Paraferrimonas [29,30]. Data generated in the DSMZ during the course of this work indicates that the fatty acids comprise, iso-C13:0 (3.7%), C13:0 (2.7%), C12:0 3OH (2.2%), iso-C14:0 (1.1%), C14:0 (1.0%), iso-C13:0 3OH (3.7%), C13:0 3OH (1.9%), iso-C15:0 (16.1%), C15:1 w8c (2.1%), C15:0 (4.5%), C14:0 3-OH (2.9%), C16:1 w9c (8.1%), C16:1w7c (4.9%), C16:0 (8.4%), iso-C15:0 3OH, (0.9%), iso-C17:0 (1.4%), C17:1 w8c (14.7%), C17:0 (5.6%), C18:1 w9c (7.8%) and C18:1 w7c (1.4%). These results are more consistent with those published in the original description , but there are differences that cannot be attributed to differences in the growth conditions. The complete absence of hydroxylated fatty acids in the work of Kasuta et al.  suggests that no attempt was made to detect them. The presence of at least two positional isomers in unsaturated fatty acids with the same chain length is indicative of the presence of at least two enzymatic pathways for introducing the double bonds. A fairly simple polar lipid pattern has been reported for Ferrimonas futtsuensis, comprising, phosphatidylglycerol, phosphatidylethanolamine and an unidentified aminophopsholipid .
Genome sequencing and annotation
Genome project history
This organism was selected for sequencing on the basis of its phylogenetic position , and is part of the Genomic Encyclopedia of Bacteria and Archaea project . The genome project is deposited in the Genome OnLine Database  and the complete genome sequence is deposited in GenBank. Sequencing, finishing and annotation were performed by the DOE Joint Genome Institute (JGI). A summary of the project information is shown in Table 2.
Growth conditions and DNA isolation
F. balearica PATT, DSM 9799, was grown in DSMZ medium 514 (Bacto Marine Broth)  at 28°C. DNA was isolated from 0.5–1 g of cell paste using Qiagen Genomic 500 DNA Kit (Qiagen, Hilden, Germany) following the standard protocol as recommended by the manufacturer, with modification st/L for cell lysis as described in Wu et al. .
Genome sequencing and assembly
The genome was sequenced using the Sanger sequencing platform (6 and 40 kb DNA libraries). All general aspects of library construction and sequencing performed at the JGI can be found at http://www.jgi.doe.gov/. The Phred/Phrap/Consed software package was used for sequence assembly and quality assessment. After the shotgun stage, reads were assembled with parallel phrap (High Performance Software, LLC). Possible mis-assemblies were corrected with Dupfinisher or transposon bombing of bridging clones (Epicentre Biotechnologies, Madison, WI) . Gaps between contigs were closed by editing in Consed, custom primer walk or PCR amplification. A total of 404 additional custom primer reactions were necessary to close gaps and to raise the quality of the finished sequence. The completed genome sequence contains 48,554 reads, achieving an average of 9.8-fold sequence coverage with an error rate less than 1 in 100,000.
Genes were identified using Prodigal  as part of the Oak Ridge National Laboratory genome annotation pipeline, followed by a round of manual curation using the JGI GenePRIMP pipeline . The predicted CDSs were translated and used to search the National Center for Biotechnology Information (NCBI) nonredundant database, UniProt, TIGRFam, Pfam, PRIAM, KEGG, COG, and InterPro databases. Additional gene prediction analysis and functional annotation was performed within the Integrated Microbial Genomes - Expert Review (IMG-ER) platform .
The genome consists of a 4,279,159 bp long chromosome with a 60.2% GC content (Table 3 and Figure 3). Of the 3,947 genes predicted, 3,803 were protein-coding genes, and 144 RNAs; twenty one pseudogenes were also identified. The majority of the protein-coding genes (72.5%) were assigned a putative function while the remaining ones were annotated as hypothetical proteins. The distribution of genes into COGs functional categories is presented in Table 4.
