Research Group in Microbial Diversity and Taxogenomics of Prokaryotes - TAXGEN-PRO

Description

Studies of prokaryotic diversity in aquatic environments (especially marine) and bacterial taxonomy.

  • Polyphasic characterisation of bacteria and archaea, especially marine, for taxonomic purposes, formal description and conservation of new bacterial taxa and generation of databases useful for their identification.
  • Phenotypic and functional characterisation: cultural, structural, physiological, biochemical and nutritional characters, determination of chemotaxonomic characters (fatty acids, polar lipids, quinones, majority proteins by MALDI-TOF, G+C).
  • Comparative genomics applied to prokaryotic taxonomy: obtaining data (new sequences, extension and/or closed) of type strains and new isolates, comparative analysis and phylogenetic studies based on conserved genes (16S rRNA gene, various essential genes), phylogenomics based on complete genomes. Determination of in silico DNA-DNA hybridisation values and ANI (Average Nucleotide Identity) and AAI (Average Aminoacid Identity) indices from genomic sequences.
  • Formal aspects: Nomenclature in prokaryote taxonomy. 

Taxonomic groups: preferably families, genera and species of the phyla Pseudomonadota (especially families Vibrionaceae, Halomonadaceae and Rhodobacteraceae) and Bacteroidota (order Flavobacteriales), among other taxa.

Goals CT
  • Generation of knowledge on microbial resources, their classification and conservation, including their possible biotechnological applications.
  • Development of methodologies for the detection, identification and quantification of relevant microorganisms in food.
Research lines
  • Genomics applied to prokaryotic taxonomy

    Studies on the application of comparative genomics to prokaryotic taxonomy. It includes both the collection of data (new sequences, extension and/or closing) of type strains and additional strains of interest to the group, as well as their subsequent analysis with computer tools and public sequences.

  • Taxonomy of marine bacteria

    Classification, identification and nomenclature of marine bacteria: polyphasic 
    characterisation (phenotypic, genomic and phylogenetic), especially of 
    alpha/gamma-proteobacteria and bacteroidetes by MLSA, DNA-DNA hybridisation, taxogenomic indices and classical phenotyping.
