In contrast, heterotrophs are organisms that cannot produce their own nutrients and require consumption of other organisms to live. Autotrophs are important parts of the ecosystem known as producers, and they are often the food source for heterotrophs.

Two kinds of lithotrophs missing in nature - Broda - 1977

WebLithotrophs (“litho” means “rock”) are chemotrophs that get energy from inorganic compounds, including hydrogen sulfide (H 2 S) and reduced iron. Lithotrophy is unique to the microbial world. The strategies used to obtain both carbon and energy can be combined for the classification of organisms according to nutritional type.

Lithotrophs

Did you know?

WebHeterotrophs can be organotrophs or lithotrophs. Organotrophs exploit reduced carbon compounds as electron sources, like carbohydrates, fats, and proteins from plants and animals. On the other hand, … WebChemolithotrophs use a variety of inorganic compounds as electron donors, with the most common substances being hydrogen gas, sulfur compounds (such as sulfide and sulfur), nitrogen compounds (such as ammonium and nitrite), and ferrous iron. Hydrogen oxidizers – these organisms oxidize hydrogen gas (H2) with the use of a hydrogenase enzyme.

WebTwo groups of lithotrophic bacteria, the existence of which may be expected on evolutionary and thermodynamical grounds, have not yet been detected: (A) photosynthetic, anaerobic, ammonia bacteria, analogous to coloured sulphur bacteria, and (B) chemosynthetic bacteria that oxidize ammonia to nitrogen with O 2 or nitrate as oxidant. WebIn contrast, the microbial mat clone sequences clustered with sequences from obligate lithotrophs representative of form IA rbcL. Clone sequences from volcanic sites fell within the form IC clade, suggesting that these sites were dominated by facultative lithotrophs, an observation consistent with biogeochemical patterns at the sites.
