Essential oils are concoctions of aromatic and volatile chemicals extracted from several plant species.
These mixes have been used by society for a variety of reasons, and they play significant functions in nature.
This study aimed to analyze the biological properties of essential oil extracted from Eucalyptus camaldulensis
leaves, including its antipseudomonal and antibiofilm effects. Antibiotics have been heavily used both to treat
bacterial infections and to stimulate fish growth, which has led to the emergence of germs that are resistant to
the drugs. The study inoculums have been defined by the McFarland 0.5 standard and disk diffusion method
has been used to analyze antimicrobial activity. The essential oils from E. camaldulensis possessed antibacterial
activity against tested Pseudomonas aeruginosa, P. fluorescens, and P. putida at 5-10 μg/disc. The antibacterial
effect has been established to be dependent on the concentration. Our findings showed that E. camaldulensis
essential oil has been a great source of antipseudomonal, and also exhibited inhibition of Pseudomonas species
biofilm formation. Based on its antibacterial and antibiofilm potential, E. camaldulensis essential oil shows
promise as a potential source of antibacterial agents. Therefore, the use of E. camaldulensis essential oil in
applications may have the potential to be a natural antibacterial agent against pathogenic and spoiling
microorganisms.
