Article
Full-text available
The present study evaluates the antimicrobial susceptibility of persister cells of Bacillus cereus and Pseudomonas fluorescens after their regrowth in suspension and as biofilms. Two conventional (benzalkonium chloride—BAC and peracetic acid—PAA) and two emerging biocides (glycolic acid—GA and glyoxal—GO) were selected for this study. Persister cel...
Article
Biofilms on food-contact surfaces act as potential reservoirs of microbial pathogens and can cause operational problems. The search for effective biofilm control agents is a significant research need. In this study, glycolic acid (GA) and glyoxal (GO) were tested in the control of biofilms formed by Bacillus cereus and Pseudomonas fluorescens. Benz...
Article
Full-text available
Biofilm control is mainly based on chemical disinfection, without a clear understanding of the role of the biocides and process conditions on biofilm removal. This study aims to understand the effects of a biocide (benzyldimethyldodecyl ammonium chloride—BDMDAC) and mechanical treatment (an increase of shear stress -τw) on single- and dual-species...
Article
Biofouling is the unwanted accumulation of deposits on surfaces, composed by organic and inorganic particles and (micro)organisms. Its occurrence in industrial equipment is responsible for several drawbacks related to operation and maintenance costs, reduction of process safety and product quality, and putative outbreaks of pathogens. The understan...
Article
The development of effective disinfection strategies, including the search for new active biocides, is a priority research for the food industry. Glycolic acid (GA) and glyoxal (GO) are two glycolysis by-products approved as biocides for surface disinfection, whose antimicrobial action remains to be understood. This study focused on the understandi...
Article
Filamentous fungi (ff) are consistently recognized as drinking water (DW) inhabitants, typically harboured in biofilms. Their sessile behaviour is still poorly understood. This study aimed the evaluation of the influence of several abiotic factors (substratum, hydrodynamic conditions and nutrient availability) on biofilm formation by Penicillium br...
