Sentence examples for mutant biofilms when from inspiring English sources
Interestingly, there was no difference between WT and agr (quorum sensing) mutant biofilms when grown in flow cells.
In keeping with these observations, strong effervescence was observed when H2O2 was added to the biofilms of both wild type strains and of the katA mutant, whereas no effervescence was observed for the B. cenocepacia katB mutant biofilms.
In addition, these mutant biofilms were much more easily removed from surfaces by a surfactant treatment.
As observed previously [7], the cidA mutant biofilm contained significantly reduced levels of eDNA associated with the biofilm (Fig 2B).
In the following, the wild-type and the cheR1 mutant biofilm underwent structural rearrangement.
The biofilm assay revealed that ethanol did not completely dissolve the biofilm mass and extract the crystal violet stain for the PGN_0274 mutant biofilm (see Additional file 1).
Earl et al (2015) also tested a rpoE knockout mutant that indicated a similar trend to wild-type bacteria biofilm when exposed to glucocorticosteroids. Thus, evidence was provided whereby corticosteroids mediate phenotypes related to the RpoE signalling pathway.
Indeed, all the mutants we tested were nonmotile (fig. 5 A) and lost between 12% and 45% of their ability to form a biofilm when compared with the wild-type strain (fig. 5 B).
The observation that the PilA-deficient mutant produced biofilms on glass or Fe(III) oxide-coated glass surfaces that were ca. half those of wild-type cells when fumarate was provided as an electron acceptor, led to the suggestion that the pili might also play an important structural role in biofilm formation [45].
This suggests that the effect of the inhibitor cocktail on biofilm formation cannot be explained by its impact on growth of the sarA mutant in biofilm medium.
Genome-wide analysis of deletion mutants revealed that eight genes involved in lipopolysaccharide (LPS) synthesis exhibited a significant degree of reduction in biofilm formation when disrupted.
