Biofilm mass
WebMar 24, 2016 · The biofilm suspension was filtered through a preweighted filter (0.45 μm) and dried in an incubator at 105 °C for 2 h, after which the filter was weighed again. The dry mass of the biofilm was calculated based on mass … WebThe frequency of biofilm production in S. aureus was 73.1%, and most of the isolates were moderate biofilm producers (38.8%). The presence of intracellular adhesion (ica) operon among these isolates was 85.7% and also significantly associated with the strength of biofilm mass formation. Ica A was the predominant biofilm-producing gene (42.9%).
