Project description:The metagenomes of marine prokaryotes from coastal seawaters in Malaysia are reported in this study. The investigation of the microbial communities using 16S rRNA gene amplicon metagenomic sequencing revealed that majority of the bacteria in the seawater samples remain unclassified.
Project description:We report here the draft genome sequences of two Chitinophagaceae bacteria, IBVUCB1 and IBVUCB2, assembled from metagenomes of surface samples from freshwater lakes. The genomes are >99% complete and may represent new genera within the Chitinophagaceae family, indicating a larger diversity than currently identified.
Project description:We report here the draft genome sequences of Hydrogenophaga sp. strains IBVHS1 and IBVHS2, two bacteria assembled from the metagenomes of surface samples from freshwater lakes. The genomes are >95% complete and may represent new species within the Hydrogenophaga genus, indicating a larger diversity than currently identified.
Project description:We report here the draft genome sequences of Sphingomonas sp. IBVSS1 and IBVSS2, two bacteria assembled from the metagenomes of surface samples from freshwater lakes. The genomes are >99% complete and may represent new species within the Sphingomonas genus, indicating a larger diversity than currently identified.
Project description:This work reports the method ClassiPhage to classify phage genomes using sequence derived taxonomic features. ClassiPhage uses a set of phage specific Hidden Markov Models (HMMs) generated from clusters of related proteins. The method was validated on all publicly available genomes of phages that are known to infect Vibrionaceae. The phages belong to the well-described phage families of Myoviridae, Podoviridae, Siphoviridae, and Inoviridae. The achieved classification is consistent with the assignments of the International Committee on Taxonomy of Viruses (ICTV), all tested phages were assigned to the corresponding group of the ICTV-database. In addition, 44 out of 58 genomes of Vibrio phages not yet classified could be assigned to a phage family. The remaining 14 genomes may represent phages of new families or subfamilies. Comparative genomics indicates that the ability of the approach to identify and classify phages is correlated to the conserved genomic organization. ClassiPhage classifies phages exclusively based on genome sequence data and can be applied on distinct phage genomes as well as on prophage regions within host genomes. Possible applications include (a) classifying phages from assembled metagenomes; and (b) the identification and classification of integrated prophages and the splitting of phage families into subfamilies.
Project description:The unclassified marine gammaproteobacterium BDW918, which utilizes volatile fatty acids but not most common carbohydrates and amino acids, was isolated from Dokdo seawater in South Korea. Here we present a draft genome of the strain BDW918, which encodes many putative genes related to fatty acid metabolism and aromatic hydrocarbon degradation.
