Final answer:
Lithotrophy is a metabolic process in which bacteria obtain energy from inorganic compounds. Examples of lithotrophic bacteria include Hydrogenobacter spp., Thiobacillus spp., Acidithiobacillus ferrooxidans, and Nitrosomonas spp.
Step-by-step explanation:
Lithotrophy is a metabolic process in which bacteria obtain energy from inorganic compounds. Hydrogenobacter spp., Thiobacillus spp., Acidithiobacillus ferrooxidans, and Nitrosomonas spp. are all examples of lithotrophic bacteria.
Hydrogen oxidizers such as Hydrogenobacter spp. use hydrogen as an energy source for oxidation and growth.
Sulfur oxidizers like Thiobacillus spp. oxidize sulfur compounds like hydrogen sulfide for energy production.
Iron oxidizers such as Acidithiobacillus ferrooxidans obtain energy by oxidizing ferrous iron.
Nitrifying bacteria like Nitrosomonas spp. convert ammonia (NH3) to nitrites (NO2-) as part of the nitrogen cycle.
