A novel bacterial strain, designated HK31-PT, was isolated from a deep subsurface geothermal aquifer in southwestern Iceland. Phylogenetic analyses, based on 16S rRNA gene sequences, revealed that the strain was […]

Non-thermodynamic Factors Affect Competition Between Thermophilic Chemolithoautotrophs From Deep-sea Hydrothermal Vents
Various environmental factors, including H2 availability, metabolic tradeoffs, optimal growth temperature, stochasticity, and hydrology, were examined to determine if they affect microbial competition between three autotrophic thermophiles.
