Implicating the glutathione-gated potassium efflux system as a cause of electrophile-induced activated sludge deflocculation

CB Bott, NG Love - Applied and Environmental Microbiology, 2004 - Am Soc Microbiol
The glutathione-gated K+ efflux (GGKE) system represents a protective microbial stress
response that is activated by electrophilic or thiol-reactive stressors. It was hypothesized that …

Activated sludge deflocculation in response to chlorine addition: the potassium connection

RF Wimmer, NG Wimmer - Water environment research, 2004 - Wiley Online Library
Chlorination is often used to control filamentous bulking in activated sludge systems. Pure
culture and mixed‐liquor experiments showed that soluble potassium (K+) concentrations …

INVESTIGATING THE ROLE OF OXIDATIVE STRESS MECHANISMS IN CHEMICALLY INHIBITIED NITRIFIERS

RT Kelly, NG Love - WEFTEC 2004, 2004 - accesswater.org
Nitrification is one of the most susceptible processes in wastewater treatment to upset by
shock loads of toxic chemicals. Previous experiments have shown that nitrification in …
