Lithotrophs
WebObligate lithotrophs (e.g., ammonia oxidizers) and facultative lithotrophs (e.g., CO and hydrogen oxidizers) collectively comprise a phylogenetically diverse functional group that contributes significantly to carbon and nitrogen cycles in soils and plays important roles in trace gas dynamics (e.g., carbon monoxide and nitrous and nitric oxides) that affect … Web5 jul. 2024 · Organotrophs vs. lithotrophs. Another way of grouping heterotrophs is by the type of compounds they use as electron sources. Organotrophs, in particular, are heterotrophs that use reduced carbon compounds, e.g. carbohydrates, fats, and proteins.In contrast, lithotrophs are heterotrophs that use inorganic compounds (e.g. ammonium, …
