Metagenome-Assembled Genomes of Four Southern Ocean Archaea Harbor Multiple Genes Linked to Polyethylene Terephthalate and Polyhydroxybutyrate Plastic Degradation.

Here, we present four archaeal metagenome-assembled genomes (MAGs) (three MAGs and one MAG) from a polar upwelling zone in the Southern Ocean. These archaea harbor putative genes encoding enzymes such as polyethylene terephthalate (PET) hydrolases (PETases) and polyhydroxybutyrate (PHB) depolymerases, which are associated with microbial degradation of PET and PHB plastics.

Microbial ecology of the Southern Ocean.

The Southern Ocean (SO) distributes climate signals and nutrients worldwide, playing a pivotal role in global carbon sequestration. Microbial communities are essential mediators of primary productivity and carbon sequestration, yet we lack a comprehensive understanding of microbial diversity and functionality in the SO. Here, we examine contemporary studies in this unique polar system, focusing on prokaryotic communities and their relationships with other trophic levels (i.

Draft genome sequence of Thermoactinomyces sp. strain AS95 isolated from a Sebkha in Thamelaht, Algeria.

The members of the genus Thermoactinomyces are known for their protein degradative capacities. Thermoactinomyces sp. strain AS95 is a Gram-positive filamentous bacterium, isolated from moderately saline water in the Thamelaht region of Algeria.

The Geobacillus Pan-Genome: Implications for the Evolution of the Genus.

The genus Geobacillus is comprised of a diverse group of spore-forming Gram-positive thermophilic bacterial species and is well known for both its ecological diversity and as a source of novel thermostable enzymes. Although the mechanisms underlying the thermophilicity of the organism and the thermostability of its macromolecules are reasonably well understood, relatively little is known of the evolutionary mechanisms, which underlie the structural and functional properties of members of this genus. In this study, we have compared 29 Geobacillus genomes, with a specific focus on the elements, which comprise the conserved core and flexible genomes.

Draft Genome Sequence of Thermophilic Geobacillus sp. Strain Sah69, Isolated from Saharan Soil, Southeast Algeria.

Geobacillus spp. are potential sources of novel enzymes, such as those involved in the degradation of recalcitrant polymers. Here, we report a Geobacillus genome that may help reveal genomic differences between this strain and publicly available representatives of the same genus from diverse niches.

Draft Genome Sequence of Taylorella equigenitalis Strain ERC_G2224 Isolated from the Semen of a Lipizzaner Stallion in South Africa.

Taylorella equigenitalis is the causative agent of contagious equine metritis (CEM), a sexually transmitted infection of horses. We report here the genome sequence of T. equigenitalis strain ERC_G2224, isolated in 2015 from a semen sample collected in 1996 from a Lipizzaner stallion in South Africa.

Intraclonal genome diversity of Pseudomonas aeruginosa clones CHA and TB.

Background: Adaptation of Pseudomonas aeruginosa to different living conditions is accompanied by microevolution resulting in genomic diversity between strains of the same clonal lineage. In order to detect the impact of colonized habitats on P. aeruginosa microevolution we determined the genomic diversity between the highly virulent cystic fibrosis (CF) isolate CHA and two temporally and geographically unrelated clonal variants.
