Role of quorum sensing and antimicrobial component production by Serratia plymuthica in formation of biofilms, including mixed biofilms with Escherichia coli

Article Abstract:

The role of quorum sensing and of quorum-sensing-dependent production of an antimicrobial compound (AC) on biofilm formation by RVH1 and on the cocultivation of RVH1 and Escherichia coli in planktonic cultures or in biofilms is investigated. Biofilm formation of Serratia plymuthica is not affected by the knockout of splI or SplR, the S. plymuthica homologs of the luxI or luxR quorum-sensing gene, respectively, or by the knockout of AC production.

Induction of Shiga toxin-converting prophage in Escherichia coli by high hydrostatic pressure

Article Abstract:

The effect of high hydrostatic pressure (HHP) treatment on lysogenic lambdoid Shiga toxin (Stx)-converting bacteriophages is investigated. The HHP can initiate the lytic cycle of Stx prophages in some Escherichia coli hosts and this induction persists at pressures relevant in the food industry when the pressure resistance of lysogens is increased either by the surrounding food matrix or intrinsically by mutation.
