Mesosaprobe

Mesosaprophytes (from the Greek mesos - middle + sapros - rotten) are heterotrophic bacteria that oxidize organic substances of plant origin, intermediate between neuogens and facultative aerobic autotrophs. Mesosaprobionts are common in well-aerated bodies of water (rivers, lakes, quarries), where some mixing of water takes place. These are organisms with fairly complex metabolic activity, which allows them to largely obtain vital resources from the biomass of organisms with strictly limited substrate availability (unlike autotrophs, which are almost not limited by current water conditions). The term “mesosarobiont” emphasizes, first of all, the significant relationship to the life of aquatic industries, where microorganisms form large communities that ferment hydrobiological wastes, which practically cannot be classified as either autotrophs or heterotrophs of a strict definition. In essence, this term is a kind of compromise between the stratification of organisms in relation to the source of energy and substrate, as well as the role in the implementation of aquatic biobenthos and its transit status. The so-called obligate heterotrophs, using available habitats (bottom sediments, stones, open
