Description

Haliscomenobacter are strictly aerobic heterotrophs 5. Cells grow as 'needle-like' filaments, that extend from activated sludge flocs 5. They are commonly observed and can be implicated in bulking 1 5 6. In axenic culture glucose, glucosamine, lactose, sucrose and starch were found to be excellent carbon and energy sources 5. Starch, gelatin 5 and various amino acids are hydrolysed 7 8. Poly-3-hydroxybutyrate is not produced 5. In situ studies indicate active uptake of propionate, glucose and N-acetylglucosamine along with some exoenzymic activity. Substrates were only assimilated with oxygen present 6.
