Description

Trichococcus are fermentative organisms capable of both aerobic and anaerobic growth 2 3 4. Some members of the genus have a filamentous morphotype and have been implicated in bulking 5. High abundance in activated sludge is influenced by a high level of immigration from the influent. However a positive growth rate in activated sludge is noted 6.
