Pethia didi markings rather than one. Pethia didi Pethia didi is a species of cyprinid fish which has only been recorded in the vicinity of Myitkyina and Indawgyi Lake in the north of Myanmar. This is a small fish which can reach a length of SL. It is generally brownish with a dark vertical bar just behind the operculum and a round dark blotch on the caudal peduncle. The species "P. tiantian" – with a range close to "P. didi" – is similarly marked, but "P. didi" can be distinguished by its truncated lateral line, deeper body and longer dorsal fin, with
Polyphosphate-accumulating organisms to certain amino acids as carbon and energy source. The storage compound that they use to store the amino acids that these organisms take up under anaerobic conditions has not been identified. These bacteria have been observed in some EBPR plants in Denmark (where they were discovered) but their wider distribution is unknown. Polyphosphate-accumulating organisms Polyphosphate-accumulating organisms (PAOs) are a group of bacteria that, under certain conditions, facilitate the removal of large amounts of phosphorus from wastewater in a process, called enhanced biological phosphorus removal (EBPR). PAOs accomplish this removal of phosphate by accumulating it within their cells as polyphosphate.
