BackgroundA moderately thermophilic, slightly halophilic, aerobic, Gram-stain negative, bacterial strain, SLM16, was isolated from a mixed of seawater–sand-sediment sample collected from a coastal fumarole located in Whalers Bay, Deception Island, Antarctica. The aim was to screen for thermophilic microorganisms able to degrade primary amines and search for amine transaminase activity for potential industrial application.ResultsIdentification and partial characterization of the microorganism… 
Characterization of a novel thermostable (S)-amine-transaminase from an Antarctic moderately-thermophilic bacterium Albidovulum sp. SLM16.
Results indicate that ATA_SLM16 is an excellent candidate for potential applications in biocatalytic synthesis, and the first report of the characterization of a thermostable (S)-ATA discovered by means of in vivo screening of thermophilic microorganisms.
Microbial Communities Present in Hydrothermal Sediments from Deception Island, Antarctica
A multidisciplinary study about sediments obtained by deposition during 4 years in Antarctica, revealing a high influence of the physicochemical conditions in the microbial populations and their distribution, offering valuable data on the interaction between the island and water microbiota.
Biotransformation of 2,4,6-Trinitrotoluene by Pseudomonas sp. TNT3 isolated from Deception Island, Antarctica.

Identification of novel thermostable taurine–pyruvate transaminase from Geobacillus thermodenitrificans for chiral amine synthesis
A novel thermostable TPTA from Geobacillus thermodenitrificans is cloned and overexpressed in Escherichia coli and shows relatively good activity toward ketoses, suggesting its potential for catalyzing the asymmetric synthesis of chiral amino alcohols.
Biochemical characterization of thermostable ω-transaminase from Sphaerobacter thermophilus and its application for producing aromatic β- and γ-amino acids.
Among the various beta and gamma amino acids produced via asymmetric synthesis, (S)-4-amino-4-(4-methoxyphenyl)-butanoic acid showed highest analytical yield (82%) with excellent enantiomeric excess (>99%).
Rapid and sensitive kinetic assay for characterization of omega-transaminases.
A fast kinetic assay was developed based on the conversion of the widely used model substrate alpha-methylbenzylamine, which is commonly accepted by most of the known omega-TAs, and the data obtained were in excellent accordance with a standard capillary electrophoresis assay.
