Biofilms: an emergent form of bacterial life - Nature
WebFeb 1, 2001 · Biofilm optical density, measured as intensity reduction of a light beam transmitted through the biofilm, correlates with biofilm mass, measured as total carbon and as cell mass. The method is more sensitive and less labor intensive than other commonly used methods for determining extent of biofilm mass accumulation. WebDec 1, 2024 · The effect of NO on biofilms is mostly studied in P. aeruginosa; however, it also induces dispersion of biofilms formed by other species as well. 500 nM of SNP was able to reduce Bacillus licheniformis biofilm mass by 90%, while 10 μM SNP resulted in a 60% biomass reduction of a Staphylococcus epidermidis biofilm [34]. how many banks failed in 2023
