Which chemosynthetic bacteria are especially important for agriculture?

Chemosynthetic bacteria are organisms that use inorganic molecules as a source of energy and convert them into organic matter. Chemosynthesis bacteria, unlike plants, obtain their energy from the oxidation of inorganic molecules, and not from photosynthesis. Chemosynthetics bacteria use inorganic molecules such as ammonia, molecular hydrogen, sulfur, hydrogen sulfide, and iron iron to produce organic compounds that are important in agriculture.
