chemoautotrophic bacteria are a type of bacteria that is autothropic and can oxidize an inorganic object. Once it oxidieze the object it secures the necessary energy of that reduced substance present in their environment. It
can make complex organic nutritive compounds from simple inorganic sources. no sunlight needed. It can be compare on plants photosynthesis but without sunlight.
Autotrophic bacteria obtain the carbon that they need to sustain survival and growth from carbon dioxide (CO2). To process this carbon source, the bacteria require energy. Chemoautotrophic bacteria obtain their energy from the oxidation of inorganic (non-carbon) compounds. That is, they derive their energy from the energy already stored in chemical compounds. By oxidizing the compounds, the energy stored in chemical bonds can be utilized in cellular processes. Examples of inorganic compounds that are used by these types of bacteria are sulfur, ammonium ion (NH4+), and ferrous iron (Fe2+).
Chemoautotrophs get their energy from chemicals they collect from outside their bodies. They use the energy from those chemicals to power the production of other chemicals. Typically they use hydrogen sulfide as the energy source.
