20.500.12556/RUL-154083 Cold plasma for sustainable control of hygienically relevant biofilms the interaction of plasma distance and exposure time This study aimed to analyse the efficacy of a new cold plasma device adapted for treatment with a low power consumption. We tested the reduction of bacterial cells in biofilms of E. coli, S. aureus and P. aeruginosa. The results show significant differences between bacterial cells, suggesting that Gramme-positive S. aureus is less susceptible to plasma treatment than Gramme-negative E. coli and P. aeruginosa. Increasing the exposure time and decreasing the distance decreases the number of cells in the biofilm. However, the combination of close distance and long exposure time resulted in synergistic effects. We demonstrated a reduction of up to 6.6 log CFU cm$^2$ for E. coli at 1 mm and an exposure time of 60 seconds. All these indicate that the new cold plasma jet device can be an important key to ensuring hygiene and numerous applications in medicine and engineering are possible. cold plasma biofilms bacterial reduction treatment time and distance hladna plazma biofilmi redukcija bakterij čas obdelave in razdalja true false true Angleški jezik Slovenski jezik Članek v reviji 2024-01-24 12:30:12 2024-01-24 12:30:18 2024-01-25 03:42:45 0000-00-00 00:00:00 2024 0 0 Str. 340–354 no. 1 Vol. 34 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 613 1369-1619 10.1080/09603123.2022.2149710 131261699 Cold_plasma_for_sustainable_control_of_hygienically_relevant_biofilms._The_interaction_of_plasma_distance_and_exposure_time.pdf Cold_plasma_for_sustainable_control_of_hygienically_relevant_biofilms._The_interaction_of_plasma_distance_and_exposure_time.pdf 1 3126C75DEAB324CEB05D1333EB801B71 b8be9d67b04a20d0cc9678910f92344eaae5ce24252537b52e49738b65ea0026 2d481efc-baac-11ee-bcde-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180244 https://www.tandfonline.com/doi/full/10.1080/09603123.2022.2149710 1 f4217062-baab-11ee-bcde-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=180243 Biotehniška fakulteta Zdravstvena fakulteta 0 0 0
