Hypothesis
Can Stenotrophomonas maltophilia effectively degrade aflatoxin B1?
Conclusion
Stenotrophomonas maltophilia can degrade aflatoxin B1 by 82.5% in a liquid culture medium.
Supporting Evidence
- Isolate 35-3 reduced AFB1 by 82.5% after 72 hours at 37 °C.
- The culture supernatant was more effective than viable cells and cell extracts in degrading AFB1.
- Degradation was influenced by temperature, pH, and metal ions.
Takeaway
Some bacteria can eat harmful toxins like aflatoxin B1, and one type called Stenotrophomonas maltophilia is really good at it.
Methodology
Bacterial isolates were screened from 65 samples using a coumarin medium, and their ability to degrade aflatoxin B1 was tested in liquid cultures.
Limitations
The study primarily focused on one bacterial isolate and did not explore the long-term effects of degradation products.
