The bacteria, which are chemolithotrophic
, obtain their energy from the oxidation of pyrite and added sulfur.

4] is referred to as chemolithotrophic
oxidation of sulfur (Kelly, 1982) is favorable to odor reduction; therefore, higher S[O.
Acidithiobacillus thiooxidans is a chemolithotrophic
acidophilic, obligately autotrophic bacterium which derives its energy by oxidizing reduced or partially reduced sulfur compounds and obtains its carbon by fixing carbon dioxide from the atmosphere .
Since, mine overburden represents hostile environment but rich is sulfur and iron components in the form of pyrite, the expected group of bacteria in fresh mine overburden spoil are chemolithotrophic
, sulfur and iron oxidizers.
Some studies have indicated chemolithotrophic
bacteria activities in caves, causing biofilms and snottites, which form as extensions of microbial biofilms that coat the walls and ceilings of caves (Hose et al.
a mesophilic obligately chemolithotrophic
bacterium isolated from a deep-sea hydrothermal vent in the Fiji Basin.
Carboxysomes are proteinaceous microcompartments that play an integral part in the metabolism of cyanobacteria and many chemolithotrophic

ammonium-oxidising community in a nitrogen saturated acid forest soil in relation to pH-dependent nitrifying activity.
The physiology and ecology of sulfate- reducing bacteria, methanogenic bacteria, hyperthermophiles, and fermentative and chemolithotrophic
bacteria are covered.
To our knowledge this is the first demonstration of [metallic iron] as an energy source for growth of any organism and thus represents a novel type of chemolithotrophic
energy metabolism,' microbiologist Lacy Daniels and his colleagues at the University of Iowa in Iowa City report in the July 31 SCIENCE.
