Genome sequences of four agarolytic bacteria from the Bacteroidia and Gammaproteobacteria.

Here we present the genomes of four marine agarolytic bacteria belonging to the Bacteroidota and Proteobacteria. Two genomes are closed and two are in draft form, but all are at least 99% complete and offer new opportunities to study agar-degradation in marine bacteria.

Genomic and phenotypic characterization of a red-pigmented strain of isolated from an Antarctic microbial mat.

The McMurdo Dry Valleys of Antarctica experience a range of selective pressures, including extreme seasonal variation in temperature, water and nutrient availability, and UV radiation. Microbial mats in this ecosystem harbor dense concentrations of biomass in an otherwise desolate environment. Microbial inhabitants must mitigate these selective pressures specialized enzymes, changes to the cellular envelope, and the production of secondary metabolites, such as pigments and osmoprotectants.
