Antimicrobial Effectiveness

Antimicrobial Effectiveness

The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

Physical Methods for Controlling Microbial Growth: Radiation and Filtration

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.

Chemical Agents for Microbial Control

Chemical Agents for Microbial Control

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Background:

Plasma-activated water (PAW) exhibits broad biological activities, including antibacterial and anti-biofilm effects.
PAW's mechanisms involve bacterial membrane damage and diffusion into extracellular matrices.
Trace metal ions and solution acidification are implicated in PAW's biological effects.

Purpose of the Study:

To investigate the key factors contributing to the antibacterial activity of PAW.
To determine the role of metal ions and solution acidification in PAW's biological effects.
To identify potential artifacts in reported PAW biological activities.

Main Methods:

Treatment of water using gas discharge plasma.
Analysis of PAW composition, including trace metal ions (copper, zinc).
Assessment of antibacterial and anti-biofilm activities.
Evaluation of solution acidification effects.

Main Results:

PAW demonstrated significant antibacterial and anti-biofilm activity.
Trace amounts of copper and zinc ions were found to play a key role in bacterial inactivation.
Solution acidification caused by reactive species was essential for the observed activities.
The contribution of metal ions varied depending on the plasma working gases used.

Conclusions:

While PAW shows promising antibacterial and anti-biofilm properties, metal ions and acidification are crucial contributing factors.
Potential artifacts in reported biological activities of PAW should be carefully considered in future research.
Further studies are needed to fully elucidate the complex mechanisms underlying PAW's biological effects.
