Hypothesis
This study aims to determine the biological activity of extracts obtained from Origanum vulgare L. by supercritical CO2 extraction using different reaction conditions and compositions.
Conclusion
Oregano extracts obtained by supercritical CO2 extraction show significant antimicrobial and antibiofilm activity against various bacteria and fungi.
Supporting Evidence
- The extracts showed antimicrobial activity against bacteria like Salmonella and Listeria.
- Fluorescence microscopy revealed changes in fungal cell viability and morphology.
- Antibiofilm properties were stronger against Gram-positive bacteria.
- Phytochemical analysis identified several bioactive compounds in the extracts.
Takeaway
Oregano extracts can help fight germs and prevent biofilms, which are like sticky layers of bacteria, making them useful for food safety.
Methodology
The study used supercritical CO2 extraction to obtain oregano extracts and tested their antimicrobial and antibiofilm properties against various microorganisms.
Limitations
The study's results may vary based on extraction conditions and the specific microorganisms tested.
