Prevention of Gordonia and Nocardia Stabilized Foam Formation by Using Bacteriophage GTE7 Academic Article uri icon


  • ABSTRACTMost activated sludge treatment plants suffer from the presence of foams on the surfaces of their aeration reactors. These are often stabilized by hydrophobic mycolic acid-synthesizing actinobacterial species. A polyvalentSiphoviridaephage, GTE7, which lysed severalGordoniaandNocardiaspecies, is described here. Its genome has a modular structure similar to that described forRhodococcusphage ReqiDocB7. In laboratory-scale experiments, we showed that GTE7 prevents stabilization of foams by theseGordoniaandNocardiaspecies.
