Salmonella biyofilmleri üzerine dezenfektanların etkisi
Özet
In this study, the effects of disinfectants commonly used in food industry on different morphotype biofilms of S. Typhimurium, S. Infantis and S. subsp. Roughform are determined. Ethanol, sodium hypochloride, chlorheksidine digluconade, etilendiamintetraasetik acid, citric acid and hydrogen peroxide have been used as disinfectants. They have been applied in different concentrations and different times (1 to 5 minutes). While galvanized stainless steel surface has been used in order to show the dissimilarities of biofilm morphotype sensitivity, microtiter plate technique has been used in order to show the effectiveness of disinfectants on sanitizing biomass. It has been observed that there is no significant difference in the sensitivity of those rdar, bdar and pdar morphotyped biofilms towards these five disinfectants except hydrogen peroxide. Also, ethanol, chlorheksidine digluconade and sodium hypochloride have abolished 100 % of these different morphotyped biofilms when compared to other disinfectants. It has been observed that the disinfection qualities and abilities of those disinfectants to extract the biomass are not parallel to each other. Chlorheksidine digluconade has abolished 100 % of all the biofilms while it has not succeeded in extracting the biomass. The most effective disinfectant on sanitizing and extracting the biomass has been the sodium hypochloride. As a result, bearing both the disinfection and biomass-extracting features of a disinfectant will contribute to an effective sanitation process.
