Abstract :Background: Atmospheric pressure cold plasma is a type of non-thermal plasma used for antimicrobial activity in the health, food and agriculture sectors. This study was carried out to investigate the efficacy of atmospheric pressure cold plasma on different bacterial isolates. Materials and Methods: The study was conducted on standard reference bacterial strains; Escherichia coli (O157:H7), Bacillus subtilis (ATCC 6633), Enterobacter aerogenes (ATCC 13048), Rhodococcus equi (ATCC 6939), Salmonella typhimurium (ATCC 14028), Enterococcus feacalis (ATCC 2912) and field isolates; 12 Escherichia coli isolates, 22 Staphylococcus spp, 18 Klebsiella spp., 2 Enterococcus spp., 3 Acinetobacter spp., 8 Candida spp., 1 Morgarella mongarii, 2 Corynebacterium spp., 1 Streptococcus pyogenes. Atmospheric pressure cold plasma jet and plasma activated medium (PAM) were applied to the isolates and their efficacy was investigated. Results: As a result of the study, it was found that cold plasma was effective against Escherichia coli (O157:H7), Enterobacter aerogenes (ATCC 13048), Salmonella typhimurium, Rhodococcus equi (ATCC 6939) and Enterococcus feacalis (ATCC 2912) among standard bacterial strains, while it was effective against Streptococcus pyogenes (group A Bet) and Staphylococcus epidermidis among field isolates. Conclusions: As a result of our study, the antimicrobial activity of atmospheric pressure cold plasma and PAM was demonstrated, and we believe that it will contribute to the health, food and agriculture sectors.
