Summary
Cold atmospheric plasma effectively destroys Staphylococcus aureus. Longer treatment times with cold plasma significantly reduce bacterial colonies, with 10 minutes eliminating them completely.
Area of Science:
- Microbiology
- Plasma Physics
- Biotechnology
Background:
- Staphylococcus aureus is a common pathogen.
- Antibiotic resistance is a growing concern.
- Cold atmospheric plasma (CAP) is an emerging technology for microbial inactivation.
Purpose of the Study:
- To evaluate the efficacy of CAP in reducing Staphylococcus aureus.
- To determine the effect of varying CAP treatment durations on bacterial destruction.
Main Methods:
- Staphylococcus aureus cultures were prepared on LB Agar medium.
- Cultures were exposed to CAP for 5, 7, and 10 minutes.
- Bacterial colony counts were assessed post-incubation.
Main Results:
- CAP treatment significantly reduced Staphylococcus aureus colonies compared to the control.
- A 10-minute CAP treatment resulted in zero bacterial colonies.
- Increased treatment duration correlated with greater bacterial reduction.
Conclusions:
- The developed CAP jet device effectively inactivates bacteria.
- CAP offers a promising rapid sterilization method.
- Treatment duration is a critical factor in CAP efficacy.

Radiation and filtration are essential tools for microbial control, targeting microorganisms through distinct mechanisms. Radiation eliminates microbes by damaging their DNA, either killing them or inhibiting their growth. Based on wavelength, radiation is classified into two types: nonionizing and ionizing radiation.Non-ionizing radiation, such as UV radiation (200–400 nm), is absorbed by DNA, causing defects that effectively disinfect surfaces, air, and water, including safety cabinets.

01:23Physical Methods for Controlling Microbial Growth: Temperature
177
Heat is a widely used method to control microbial growth by targeting and denaturing cellular proteins, thereby killing or inactivating microbes. This method's effectiveness is quantified using parameters such as the thermal death point (TDP), thermal death time (TDT), and decimal reduction time (D value). TDP represents the lowest temperature at which all microorganisms in a liquid suspension are eliminated within 10 minutes, whereas TDT is the time necessary to achieve sterilization at a...
