Explanation / Answer

Bacteria Description

Possible Electron Donor

Possible Electron Acceptor

Possible Carbon Source

Aerobic heterotroph

They act as Terminal electron acceptor because during respiration they use oxygen

Use CO2 as possible carbon source

Anammox Bacteria

Some members of the anammox bacteria had been shown to respire iron (III) or manganese (IV) oxides, with formate as the electron donor

can use as electron sources or acceptors

using CO2 as the carbon source

Iron Oxidizer

H2 or S0 are use as an electron donor,serves as a primary energy source of the bacterium

In Anaerobic respiration used Fe3+ or S0 as an electron acceptor

for energy they need and multiply by oxidizing dissolve ferrous iron, the organisms cometabolized ferrous iron with an additional carbon source

Iron Reducer

Fe2+ have a positive standard reduction potential, the bioenergetics are not extremely favorable, and using oxygen as a final electron acceptor.

freshwater and marine roots used a variety of carbon and energy sources

(e.g., acetate, ethanol, succinate)

Sulfur Oxidizer

sulfide as an electron donor

nitrate as an electron acceptor under anaerobic conditions.

use methane as a carbon source

Sulfate Reducer

utilizing sulfate (SO42–) as terminal electron acceptor

use of both organic and inorganic compounds as carbon source

Acetogen

reduce acetyl–CoA to acetaldehyde and ethanol using electron donors such as NAD(H) and NADP(H)

CO use as a carbon source

Methanogen

the methyl group is the electron donor, organic matter fermentation which produce organic acids at concentrations in excess of the availability of alternative electron donors ( NO 3 - , Fe3+, SO 4 2 - )

the carboxyl group is the electron acceptor.

use CO2 as a source of carbon

Nitrate reducer

nitrogen electron acceptors in order of most to least thermodynamically favorable includenitrate (NO3?), nitrite (NO2?),

lactate as fermentable carbon source

Hydrogen oxidizer

hydrogen as electron donor

May be use oxygen as electron acceptor,

derive energy for growth and maintenance from the reaction 2H2+O2?2H2O
