Effect of water treatment with low-temperature and low-pressure glow plasma of low frequency on the growth of selected microorganisms

Figures & data

Figure 1. Comparison of prokaryotic microorganism cell growth measured as optical density (OD) in control medium (C) and plasma water-based medium (PL): A – Escherichia coli, B – Staphylococcus aureus, C – Enterococcus faecalis, D – Klebsiella pneumoniae. The tests were carried out in triplicates and averaged. Standard errors were below 5%.

Figure 2. Comparison of eukaryotic cell growth measured as optical density (OD) in control medium (C) and plasma water-based medium (PL). A – Saccharomyces cerevisiae, B – Candida albicans, C – Yarrowia lipolytica, D – Aspergillus niger. The tests were carried out in triplicates and averaged. Standard errors were below 5%.
