Comparative Genome Analysis of the Photosynthetic Betaproteobacteria of the Genus : Heterogeneity within Strains Assigned to and Description of sp. nov. as a New Species.

The genome sequences for DSM 168 and four strains assigned to (DSM 110, DSM 111, DSM 112, and IM 230) have been determined. One of the strains studied (IM 230) has an average nucleotide identity (ANI) of 97% to the recently reported genome of the type strain DSM 109 of and is regarded as virtually identical at the species level. The ANI of 80% for three other strains (DSM 110, DSM 111, DSM 112) to the type strain of points to a differentiation of these at the species level.

Cellulosimicrobium fucosivorans sp. nov., isolated from San Elijo Lagoon, contains a fucose metabolic pathway linked to carotenoid production.

Cellulosimicrobium strain SE3 was isolated from the San Elijo coastal lagoon near San Diego. A whole genome-based phylogenetic comparison shows great heterogeneity within the Cellulosimicrobium genus. Based on average nucleotide identity, whole genome-based comparison, and the presence of a unique L-fucose metabolic pathway, strain SE3 was shown to belong to a novel species within the genus, together with five other strains.

Sequencing of Coastal Lagoon Samples from the Piñones Lagoon, Puerto Rico, Reveals Important Role of Bacterial Sulfur Metabolism in the Lagoon Ecosystem.

This initial microbial analysis of the Piñones Lagoon shows a high representation of sulfur-oxidizing and sulfur-reducing bacteria. These species are likely responsible for maintaining sulfur homeostasis and prevent the buildup of toxic sulfur components, but may contribute to nitrogen buildup, in the mangrove ecosystem.

Draft Genome Sequences of Thiorhodococcus mannitoliphagus and Thiorhodococcus minor, Purple Sulfur Photosynthetic Bacteria in the Gammaproteobacterial Family .

We have determined the draft genome sequences of and for comparison with those of and According to average nucleotide identity (ANI) and whole-genome phylogenetic comparisons, these two species are clearly distinct from the species and .
