Alicyclobacillus hesperidum sp. nov. and a related genomic species from solfataric soils of São Miguel in the Azores.

TLDR
On the basis of the phylogenetic analysis, physiological and biochemical characteristics, and fatty acid composition the name Alicyclobacillus hesperidum is proposed for the species represented by strains FR-11T and FR-1b; a formal name for the new genomic species represented in these organisms is not proposed at this time.

Isolation of Thermoanaerobacter keratinophilus sp. nov., a novel thermophilic, anaerobic bacterium with keratinolytic activity

TLDR
This strain, which grows optimally at 70°C, pH 7.0, and 0.5% NaCl, is the first member of the genus Thermoanaerobacter that has been described for its ability to degrade native keratin, and it is shown to possess intracellular and extracellular proteases optimally active.

Degradation of crude oil by an arctic microbial consortium

TLDR
Interestingly, the five isolated strains in different combinations were unable to degrade crude oil or its components significantly, indicating the importance of the four unculturable microorganisms in the degradation of single or of complex mixtures of hydrocarbons.
