POSNEGVariableNot assessed


While Flavobacterium are commonly seen in activated sludge, their physiology in situ has not been determined. Members of the genus are aerobic with a respiratory type of metabolism 13. Anaerobic growth is also possible for some species under certain growth conditions 13 14. They are chemoheterotrophs or chemoorganotrophic 13. Various polysaccharides are hydrolyzed by several species in the genus, including starch, chitin, pectin, and carboxymethyl cellulose 13 11 8. Cells are rod shaped, however, shorter or longer filamentous cells may be produced under certain growth conditions 13. Floc forming ability has been demonstrated in pure culture 15 16 17.
