Effect of gas ultrafine bubbles on the potency of antimicrobials against Escherichia coli O157:H7 biofilms on various food processing surfaces
This study investigated the impact of incorporating gas [air, carbon dioxide (CO2), and nitrogen (N2)] UFB on the potency of chlorine (Cl2; 50, 100, and 200 ppm) and peracetic acid (PAA; 20, 40, and 80 ppm) antimicrobial (AM) solutions against fresh (3 days) and aged (30 days) E. coli O157:H7 biofilms on polypropylene, silicone, and stainless-steel surfaces. The biofilms were statically grown on polypropylene, silicone, and stainless-steel coupons (7.62 × 2.54 cm) at 25°C for 3 or 30 days by immersing in a 3-strain cocktail of E. coli. The incorporation of air, CO2, and N2 UFB in AM solutions resulted in significantly increased log reductions (2.1–3.7 logs) in fresh and aged E. coli biofilms on all surfaces compared to solutions without UFB, except for N2 UFB on aged stainless-steel biofilms and air UFB on aged polypropylene biofilms, which resulted in similar log reductions as solutions without UFB (1.5–2.1 logs).
期刊介绍：
The Journal of Food Safety emphasizes mechanistic studies involving inhibition, injury, and metabolism of food poisoning microorganisms, as well as the regulation of growth and toxin production in both model systems and complex food substrates. It also focuses on pathogens which cause food-borne illness, helping readers understand the factors affecting the initial detection of parasites, their development, transmission, and methods of control and destruction.
