Question
Chapter 15.19, Problem 1MQ
Summary Introduction
The genus Aquifex is an autotrophic hyperthermophile and strict chemolithotroph. It is the most thermophilic of all well-known bacterial groups. The Aquifex members use H2 and sulfur (S0) as electron donors and it utilizes nitrate or oxygen as electron acceptors. It grows at temperatures up to 95°C. Aquifex are microaerophilic and it is incapable to oxidize all the organic components.
