Draft genome and description of Waterburya agarophytonicola gen. nov. sp. nov. (Pleurocapsales, Cyanobacteria): a seaweed symbiont.

ABSTRACT: This work introduces Waterburya agarophytonicola Bonthond and Shalygin gen. nov., sp. nov, a baeocyte producing cyanobacterium that was isolated from the rhodophyte Agarophyton vermiculophyllum (Ohmi) Gurgel et al., an invasive seaweed that has spread across the northern hemisphere. The new species genome reveals a diverse repertoire of chemotaxis and adhesion related genes, including genes coding for type IV pili assembly proteins and a high number of genes coding for filamentous hemagglutinin family (FHA) proteins. Among a genetic basis for the synthesis of siderophores, carotenoids and numerous vitamins, W. agarophytonicola is potentially capable of producing cobalamin (vitamin B12), for which A. vermiculophyllum is an auxotroph. With a taxonomic description of the genus and species and a draft genome, this study provides as a basis for future research, to uncover the nature of this geographically independent association between seaweed and cyanobiont.

Rise of Microbial Culturomics: Noncontiguous Finished Genome Sequence and Description of Beduini massiliensis gen. nov., sp. nov.

Project description:Microbial culturomics is a new field of omics sciences that examines the bacterial diversity of human gut coupled with a taxono-genomic strategy. Using microbial culturomics, we report here for the first time a novel Gram negative, catalase- and oxidase-negative, strict anaerobic bacilli named Beduini massiliensis gen. nov., sp nov. strain GM1 (= CSUR P1440 = DSM 100188), isolated from the stools of a female nomadic Bedouin from Saudi Arabia. With a length of 2,850,586 bp, the Beduini massiliensis genome exhibits a G + C content of 35.9%, and contains 2819 genes (2744 protein-coding and 75 RNA genes including 57 tRNA and 18 rRNA genes). It is composed of 6 scaffolds (composed of 6 contigs). A total of 1859 genes (67.75%) were assigned a putative function (by COGs or by NR blast). At least 1457 (53%) orthologous proteins were not shared with the closest phylogenetic species. 274 genes (10.0%) were identified as ORFans. These results show that microbial culturomics can dramatically improve the characterization of the human microbiota repertoire, deciphering new bacterial species and new genes. Further studies will clarify the geographic specificity and the putative role of these new microbes and their related functional genetic content in health and disease. Microbial culturomics is an emerging frontier of omics systems sciences and integrative biology and thus, warrants further consideration as part of the postgenomics methodology toolbox.

High-quality draft genome sequence and description of Haemophilus massiliensis sp. nov.

Project description:Strain FF7(T) was isolated from the peritoneal fluid of a 44-year-old woman who suffered from pelvic peritonitis. This strain exhibited a 16S rRNA sequence similarity of 94.8 % 16S rRNA sequence identity with Haemophilus parasuis, the phylogenetically closest species with a name with standing in nomenclature and a poor MALDI-TOF MS score (1.32 to 1.56) that does not allow any reliable identification. Using a polyphasic study made of phenotypic and genomic analyses, strain FF7(T) was a Gram-negative, facultatively anaerobic rod and member of the family Pasteurellaceae. It exhibited a genome of 2,442,548 bp long genome (one chromosome but no plasmid) contains 2,319 protein-coding and 67 RNA genes, including 6 rRNA operons. On the basis of these data, we propose the creation of Haemophilus massiliensis sp. nov. with strain FF7(T) (= CSUR P859 = DSM 28247) as the type strain.

High-quality draft genome sequences of five anaerobic oral bacteria and description of Peptoanaerobacter stomatis gen. nov., sp. nov., a new member of the family Peptostreptococcaceae.

Project description:Here we report a summary classification and the features of five anaerobic oral bacteria from the family Peptostreptococcaceae. Bacterial strains were isolated from human subgingival plaque. Strains ACC19a, CM2, CM5, and OBRC8 represent the first known cultivable members of "yet uncultured" human oral taxon 081; strain AS15 belongs to "cultivable" human oral taxon 377. Based on 16S rRNA gene sequence comparisons, strains ACC19a, CM2, CM5, and OBRC8 are distantly related to Eubacterium yurii subs. yurii and Filifactor alocis, with 93.2 - 94.4 % and 85.5 % of sequence identity, respectively. The genomes of strains ACC19a, CM2, CM5, OBRC8 and AS15 are 2,541,543; 2,312,592; 2,594,242; 2,553,276; and 2,654,638 bp long. The genomes are comprised of 2277, 1973, 2325, 2277, and 2308 protein-coding genes and 54, 57, 54, 36, and 28 RNA genes, respectively. Based on the distinct characteristics presented here, we suggest that strains ACC19a, CM2, CM5, and OBRC8 represent a novel genus and species within the family Peptostreptococcaceae, for which we propose the name Peptoanaerobacter stomatis gen. nov., sp. nov. The type strain is strain ACC19a(T) (=HM-483(T); =DSM 28705(T); =ATCC BAA-2665(T)).

Project description:Timonella senegalensis strain JC301(T) gen. nov., sp. nov. is the type strain of T. senegalensis gen. nov., sp. nov., a new species within the newly proposed genus Timonella. This bacterial strain was isolated from the fecal flora of a healthy Senegalese patient. In this report, we detail the features of this organism, together with the complete genome sequence and annotation. Timonella senegalensis strain JC301(T) exhibits the highest 16S rRNA similarity (95%) with Sanguibacter marinus, the closest validly published bacterial species. The genome of T. senegalensis strain JC301(T) is 3,010,102-bp long, with one chromosome and no plasmid. The genome contains 2,721 protein-coding genes and 72 RNA genes, including 5 rRNA genes. The genomic annotation revealed that T. senegalensis strain JC301(T) possesses the complete complement of enzymes necessary for the de novo biosynthesis of amino acids and vitamins (except for riboflavin and biotin), as well as the enzymes involved in the metabolism of various carbon sources, chaperone genes, and genes involved in the regulation of polyphosphate and glycogen levels.

Draft genomes and descriptions of Urmitella timonensis gen. nov., sp. nov. and Marasmitruncus massiliensis gen. nov., sp. nov., isolated from severely malnourished African children using culturomics.

Project description:Two strains, designated as Marseille-P2918T and Marseille-P3646T, were isolated from a 14-week-old Senegalese girl using culturomics: Urmitella timonensis strain Marseille-P2918T (= CSUR P2918, = DSM 103634) and Marasmitruncus massiliensis strain Marseille-P3646T (= CSUR P3646, = CCUG72353). Both strains were rod-shaped, anaerobic, spore forming motile bacteria. The 16S rRNA gene sequences of strains Marseille-P2918T (LT598554) and Marseille-P3646T (LT725660) shared 93.25% and 94.34% identity with Tissierella praeacuta ATCC 25539T and Anaerotruncus colihominis CIP 107754T, their respective phylogenetically closest species with standing in nomenclature. Therefore, strain Marseille-P2918T is classified within the family Tissierellaceae and order Tissierellales whereas strain Marseille-P3646T is classified within the family Oscillospiraceae and order Eubacteriales. The genome of strain Marseille-P2918T had a size of 2.13 Mb with a GC content of 50.52% and includes six scaffolds and six contigs, and that of strain Marseille-P3646T was 3.76 Mbp long consisting of five contigs with a 50.04% GC content. The genomes of both strains presented a high percentage of genes encoding enzymes involved in genetic information and processing, suggesting a high growth rate and adaptability. These new taxa are extensively described and characterised in this paper, using the concept of taxono-genomic description.
