Abstract

The effect of single-walled carbon nanotubes (SWCNTs) on the formation and eradication of biofilms of activated sludge proteobacteria and actinobacteria of the genus Rhodococcus was studied. It has been shown that SWCNTs do not inhibit the formation of biofilms of these bacteria and do not cause their destruction, while in the presence of SWCNTs, much more massive biofilms of Alcaligenes faecalis 2 and Acinetobacter guillouiae 11h are formed. It was shown that the level of dehydrogenase activity, estimated by the reduction of tetrazolium salt to formazan, in biofilm cells formed in the presence of SWCNTs, exceeded that of biofilms in the control.
