... A or 18 ppb (w/w) was used in the biofilm prevention test and 10 – 100 nM was tested in the biofilm removal test. The cocktail of 50 ppm THPS + 10 nM Peptide A achieved 2 extra log reduction of SRB sessile cell count in the 7-day biofilm prevention test compared with 50 ppm THPS treatment alone. In the 3...

... is assumed to approximate the biofilm-associated cells (sessile) cells. This work aimed to determine the accuracy of this industry-practiced approach of assessing MIC risk from planktonic cell counts. Planktonic and sessile cell counts of two single species cultures, one of an aerobe ( Pseudomonas...

.../cn12) can show higher resistance than the same, unattached, cells6. This could suggest that it is the altered physiological state of sessile cells which renders them less susceptible to biocidc action. Cells on surfaces have different growth rates and nutritional requirements than planktonic CCIISof...
