"Gas biofilters can help remove harmful volatile organic compounds (VOCs) from the air through the action of microorganisms immobilized on the filler surface. However, unchecked growth of these microbes can clog the filters, reducing filtration performance. Quorum quenching (QQ) is known to impair bacterial biofilm formation by disrupting bacterial communication, but it’s unclear whether it can prevent microbial clogging of gas biofilters. To find out, researchers recently operated gas biofilters with and without the QQ bacterium Rhodococcus sp. BH4 in parallel. Both the normal biofilter and the QQ biofilter removed aromatic compounds from the air, but the QQBF accumulated less biomass and functioned more stably. The bacteria in the QQBF made lower amounts of extracellular polymeric substances (EPSs) thus producing a less-adhesive biofilm that degraded more easily . The QQ biofilter also had lower abundance of quorum-sensing bacteria and quorum-sensing genes. Although the mechanism of Rhodococcus sp..."
