Epinephelus labriformis Epinephelus labriformis Epinephelus labriformis, commonly called starry grouper or flag cabrilla among various other vernacular names, is a species of marine fish in the family Serranidae. The starry grouper is medium-sized fish which grows up to 60 cm. From: "The body of the starry grouper is robust and compressed. The end of the top jaw is exposed. The operculum edge has 3 flat spines; the pre-operculum is without spines. The caudal fin is rounded. The lateral line is complete, it ends at the caudal fin base and is smoothly arched. The scales are rough and relatively small." The starry grouper
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.
