Low-Load Compression Testing: a Novel Way of Measuring Biofilm Thickness

WebThe biofilm on untreated samples (Group 4) appeared as a thick and dense layer, indicating a mature bacterial biofilm (thickness of approximately 28.1±5.8 µm, Figure 1B–G4). Am-alone treatment disrupted approximately 60% biofilms and resulted in a thickness decrease to 22.2±3.5 µm ( Figure 1B – G3 ). WebMost biofilm thickness measurement techniques described in the literature require removal of the biofilm from the system, are destructive, and in addition often necessitate some form of sample preparation with consequent changes in properties (Trulear and Characklis, 1982, Capdeville et al., 1992, Lewandowski et al., 1993). design of electric motorcycle charging system

Biofilm growth on PVC and HDPE pipes impacts chlorine

WebNov 21, 2016 · A physical method extensively used to measure biofilm thickness is based on ultrasonic time-domain reflectometry (Sim et al., Citation 2013). Biofilm thickness is obtained from the difference … WebAug 31, 2007 · Here, we present low-load compression testing (LLCT) as a new method for measuring biofilm thickness. With LLCT, biofilm thicknesses are measured during compression by inducing small loads, up to 5 Pa, corresponding to 0.1% deformation, making LLCT essentially a nondestructive technique. WebMay 21, 2024 · The proposed method combines the use of CV staining to measure biofilm biomass and a tetrazolium based metabolic dye to assess the residual viable metabolizing bacteria. Such an approach permits us … design of energy cushion
