Question

The bacteria oxidising a number of inorganic compounds to obtain energy for the assimilation of CO2 are called (A) photoautotrophic bacteria (B) chemoautotrophic bacteria (C) heterotrophic bacteria (D) none of the above

Tardigrade Admin · Accepted Answer

Chemoautotrophic bacteria are without photosynthetic pigments. For the synthesis of their own organic food, they obtain carbon from carbon dioxide of the atmosphere and necessary energy from oxidation of inorganic or organic compounds, such as hydrogen sulphide, ferrous compounds, molecular hydrogen, ammonia and nitrites. Nitrifying bacteria, iron bacteria, hydrogen bacteria, sulphur bacteria all are chemoautotrophic bacteria.
