Résumé :
|
GroEL is a ubiquitous constitutively synthesized protein that is also stress inducible. Activated sludge, which is a standard biological process used in wastewater treatment systems, is made up of a diverse microbial consortium. The synthesis of GroEL in activated sludge was significantly induced after heat (42 °C) shock. The increased level of GroEL expression was shown to be due to de novo protein synthesis. We have demonstrated a method which shows that stress proteins can be detected in activated sludge, and propose their use as specific indicators of system stress.
