Chapter 16.19, Problem 1CR
Summary Introduction
Thermocrinis is a hyperthermophilic and chemolithotrophic bacterium that grows optimally at 80°C. It can oxidize H2 and S0 as electron donors and use oxygen as electron acceptor. Thermocrinis are relatives of Hydrogenobacter and Aquifex.
Thermocrinis ruber is a Gram-negative, hyperthermophilic, pink-filament-forming bacterium. It is first isolated in the hot springs in Yellowstone National Park.
