Aims The aim of this study was to test the efficacy of new and currently used biocides in the mushroom industry for inactivating Listeria monocytogenes biofilm. Methods and results A laboratory‐scale study was initially carried out to test the efficacy of eleven biocidal products against a cocktail of five L. monocytogenes strains that were grown to 3‐day biofilms on stainless steel coupons. Biocidal efficacy was then tested under clean and dirty conditions based on the EN 13697:2015 method. The results for the biocides tested ranged between 1·7‐log and 6‐log reduction of biofilm, with only the efficacy of the sodium hypochlorite‐based biocide being significantly reduced in dirty conditions. A pilot‐scale trial was then carried out on a subset of biocides against L. monocytogenes on concrete floors in a mushroom growing room and it was found that biocide efficacy in laboratory‐scale did not translate well in pilot‐scale. Conclusions Biocides that are used in the mushroom industry and potential alternative biocides were determined to be effective against L. monocytogenes biofilm in both laboratory‐scale and pilot‐scale experiments. Significance and Impact of the Study This study has direct impact for the industry as it provides information on the efficacy of currently used biocides and other biocidal products against L. monocytogenes, an added benefit to their primary use.

“…Therefore, in this study, as the plasma bubble treatment time increased, the concentration of dissolved O 3 in the water increased, eventually pasteurizing S. Typhimurium by more than 5 log CFU/mL within 5 min. Many studies have been conducted involving the application of O 3 generators for the injection of O 3 gas into water to inactivate microorganisms or decompose organic matter [13,37,38]. Since O 3 can directly oxidize various organic substances and microbial components [12], previous studies have suggested that concentrations of gas-phase or dissolved O 3 in solution are important as oxidative indicators [37,39].…”

The key reactive species generated by non-thermal plasma bubbles for the inactivation of Salmonella Typhimurium and the effects of organic matter on the inactivation efficacy were investigated. Plasma, which is primarily composed of ozone (O3), was generated by dielectric barrier discharge and injected into a solution (400 mL) as a bubble. The surviving population of S. Typhimurium decreased in proportion to the treatment time, resulting in a 5.29 log reduction after 5 min of treatment. Verification tests to specify key reactive species were conducted using an O3 destruction unit and reactive oxygen species scavengers. The results indicated that singlet oxygen (1O2) contributes substantially to the inactivation of S. Typhimurium, and that the presence of superoxide anion radicals (O2·−) from O3 is essential for the production of 1O2. When a S. Typhimurium suspension containing organic matter (final concentration: 0, 0.005, 0.05, 0.1, and 0.5 g/L), consisting of beef extract and peptone, was treated with plasma bubbles for 5, 10, 15, 20, 25, and 30 min, respectively, the potential of the plasma bubbles for inactivating S. Typhimurium successfully was verified with longer contact time, despite organic matter attenuating the inactivation efficiency in a dose-dependent manner.

“…The exposure times on enamel were 8 minutes for hydrogen peroxide and placebo and 19 minutes for oxygen and ozone. Except for the placebo, all were effective in tooth whitening, with differences between the three groups nonstatistically significant [24]. Other researchers have proposed the addition of ozone to hydrogen peroxide for dental bleaching, but is still too early to reach conclusions [25].…”

Ozone is aunstable gas, proposed in medicine filed especially for microbial infections. It can be used in the form of oxygen-ozone gas mixture , diluted in aqueous solution and in the form of ozonized oil. Its antimicrobial action is linked to damage to the cytoplasmic membrane, and so it has been proposed in different dentistry fields. The most simple application is ozonated water. The aim of this pilot study is to evaluate the effectiveness on dentinal sensitivity, of a particular device called Aquolab (Sweden & Martina , Padua , Italy), similar to a water-jet, that dispenses a mixture of water and ozone7 patients were enrolled in this pilot study, 4 female patients e 3 male patients with some difficult to eat and drink cold food. An NSR scale test was administered to the patients, to quantify the dentinal sensitivity, on groups of 3-4 dental elements. The values reported were registered. A single session of 60 seconds mixture of water and ozone was performed, with program 1 for water delivery and program 3 for ozone delivery. After the session the NSR scale test was submitted again to the patients. In 3 patients has been possible to record also the values at 1 months follow up.The average of the values found was 7,42 before the treatments and 2,5 immediately after the session with Aquolab. In one patient the value of the test at 1 months follows up was 0,5, the same that after the treatment. In another patient the value was 1 after the session and 0 after the 1months follow up; one patient reported the value of 4 at the follow up visit. All patients had improved their sensitivity.The use of ozonized water for oral infections treatment is successfully documented in the literature but there is no work on the use of this garrison to reduce this problem. This device could be considered useful to treat dentinal sensitivity without any type of collateral events. More clinical studies are needed to confirm this preliminary results.
