Bacterial coaggregation is a critical process in multispecies biofilm formation, driven by specific molecular interactions that facilitate the adhesion and aggregation of bacterial cells. These interactions are essential for the development and persistence of complex microbial communities. This review provides a comprehensive analysis of the roles of the proteosurfaceome and exoproteome in bacterial coaggregati...
The widespread and indiscriminate use of biocides poses significant threats to global health, socioeconomic development, and environmental sustainability by accelerating antibiotic resistance. Bacterial resistance development is highly complex and influenced significantly by environmental factors. Increased biocide usage in households, agriculture, livestock farming, industrial settings, and hospitals produces ...
A novel photoheterotrophic dual-species biofilm was evaluated for wastewater (WW) treatment and microbial growth under variable cell loads. For that, Chlorella vulgaris was tested under axenic conditions and in combination with three bacteria, Rhodococcus fascians, Acinetobacter calcoaceticus, and Leucobacter sp., assessing the influence of each bacterial strain in biomass productivity, growth rate, thickness, ...
Drinking water (DW) is paramount to human health, serving as a cornerstone of public health worldwide. However, DW is not a sterile product and can harbor a large diversity of microorganisms, including pathogens. This comprehensive review addresses the critical importance of DW for human health and the ongoing challenges posed by microbial pathogens and biofilms in water distribution systems. It further analyze...
Aim: Coaggregation, a highly specific cell-cell interaction mechanism, plays a pivotal role in multispecies biofilm formation. While it has been mostly studied in oral environments, its occurrence in aquatic systems is also acknowledged. Considering biofilm formation's economic and health-related implications in engineered water systems, it is crucial to understand its mechanisms. Here, we hypothesized that tra...
The presence of biofilms in drinking water distribution systems (DWDS) is responsible for water quality deterioration and a possible source of public health risks. Different factors impact the biological stability of drinking water (DW) in the distribution networks, such as the presence and concentration of nutrients, water temperature, pipe material composition, hydrodynamic conditions, and levels of disinfect...
Bacterial coaggregation is a highly specific type of cell-cell interaction, well-documented among oral bacteria, and involves specific characteristics of the cell surface of the coaggregating strains. However, the understanding of the mechanisms promoting coaggregation in aquatic systems remains limited. This gap is critical to address, given the broad implications of coaggregation for multispecies biofilm form...
Biofilm formation plays a critical concern in the food processing industry due to potential environmental, economic, and food spoilage impacts. To maintain microbial safe levels, a sanitation process, comprising cleaning and disinfection steps, needs to be periodically performed. Biocide treatment for surface disinfection is the most widely applied strategy. Owing to the critical failure of current sanitation p...
Biofilms in drinking water (DW) systems persistently challenge traditional disinfection methods due to intricate microbial interactions, with coaggregation playing a crucial role in forming multispecies biofilms. This study examined the implications of coaggregation on tolerance towards sodium hypochlorite (NaOCl) disinfection. Dual-species biofilms were formed for seven days on polyvinyl chloride coupons, comp...
