The use of active packaging technologies and biopolymeric materials are among the emerging trends for implementation sustainability in food industry. Thus, herein, bioactive transparent nanocomposite films thermoplastic starch (TPS) reinforced with bacterial nanocellulose (BNC) (1%, 5% 10% w/w, relative to starch) enriched gallic acid (GA) (1 1.5% were prepared by solvent casting method. addition BNC (≥5% w/w) GA enhanced both mechanical properties (Young's Modulus: 1.2–2.0 GPa vs. 1.0 TPS;...
Abstract Aims This study aimed to evaluate the potential of phage phSE-5 inactivate Salmonella enterica serovar Typhimurium in milk (at 4, 10 and 25°C), liquid whole egg eggshell 25°C for both matrices). Methods results Since success treatment food depends on maintaining viability towards different conditions, firstly stability at temperatures pHs was assessed. The effect against S. then assessed vitro (liquid culture medium—TSB) finally selected matrices. Phage stable long storage periods...
Bacterial inactivation using bacteriophages (or phages) has emerged as an effective solution for bacterial infections, but the screening methods used to evaluate effectiveness of phages inactivate bacteria are not fast, reliable or precise enough. The efficiency by been evaluated monitoring concentration either counting colony-forming units (CFU), a laborious and time-consuming method, optical density (OD), less sensitive method. In this study, resazurin cell viability assay was monitor from...
The bacterial adhesion to food processing surfaces is a threat human health, as these can serve reservoirs of pathogenic bacteria. Escherichia coli an easily biofilm-forming bacterium involved in surface contamination that lead the cross-contamination food. Despite application disinfection protocols, through continues occur. Hence, new, effective, and sustainable alternative approaches are needed. Bacteriophages (or simply phages), viruses only infect bacteria, have proven be effective...
The bacterial adhesion to food contact surfaces is a threat human health, as these can serve reservoir of pathogenic bacteria. Escherichia coli biofilm-forming bacterium involved in surface contamination. Despite the application disinfection protocols, contamination continues occur. Hence, new effective and sustainable approaches are needed. Bacteriophages (or simply phages), viruses that only infect bacteria, have proven be reducing biofilms. Here, phage phT4A was applied prevent reduce E....
Endolysins are bacteriophage (or phage)-encoded enzymes that catalyse the peptidoglycan breakdown in bacterial cell wall. The exogenous action of recombinant phage endolysins against Gram-positive organisms has been extensively studied. However, outer membrane acts as a physical barrier when considering use to combat Gram-negative bacteria. This study aimed evaluate antimicrobial activity SAR-endolysin LysKpV475 bacteria single or combined therapies, using an permeabilizer (polymyxin B) and...
To help halt the global spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), appropriate disinfection techniques are required. Over last years, interest in Ultraviolet-C (UV-C) radiation as a method to disinfect inanimate surfaces and personal protective equipment (PPE) has increased, mainly efficiently prevent SARS-CoV-2 from spreading allow for safe reuse said equipment. The bacteriophage ϕ6 (or simply phage ϕ6) is an RNA virus with phospholipid envelope commonly used...
Pseudomonas aeruginosa is a common cause of hospital-acquired infections and exhibits strong resistance to antibiotics. An alternative treatment option for bacterial the use bacteriophages (or phages). In this study, two distinct phages, VB_PaD_phPA-G (phPA-G) VB_PaN_phPA-Intesti (phPA-Intesti), were used as single suspensions or in phage cocktail inactivate planktonic cells biofilms P. aeruginosa. Preliminary experiments culture medium showed that phPA-Intesti (reductions 4.5–4.9 log...
