A selection of mesophilic, thermophilic and extreme thermophilic H2-producing strains, showing their optimal growth temperature, H2 yields and type of glucose transport. The type of glucose transport assigned to each organism was either retrieved from literature or based on bioinformatic analysis (This study) using the Integrated Microbial Genomes (IMG) database http://img.jgi.doe.gov/
