SCU-China # SRBioQuencher # Hydrogen sulfide(H2S) is a harmful gas in urban sewers, due to its toxicity, pungent odor, and flammability. Sulfate reducing bacteria (SRB), the main source of H2S in sewer, tend to resist the current chemical treatment once the biofilm formed. Here, we designed a predator, SRBioQuencher to kill SRB, thereby reducing the high H2S concentrations in sewers efficiently and safely. Cocktail therapy was applied by equipping SRBioQuencher with the ability to eliminate SRB biofilms by introduced glycosidases to degrade their main skeletons, inhibit the reformation of SRB biofilm by degrading the quorum sensing signal molecules, and kill SRB by the expressed antimicrobial peptides. ...
