Non-thermodynamic Factors Affect Competition Between Thermophilic Chemolithoautotrophs From Deep-sea Hydrothermal Vents

by Keith Cowing

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.
