RESEARCH | Fermented foods in the Philippines, such as burong isda (fermented fish), are not only part of our culinary heritage but also rich sources of beneficial bacteria. In this study, we isolated and studied two strains of Limosilactobacillus fermentum—a type of lactic acid bacteria—from burong isda collected in Arayat, Pampanga. Using both laboratory tests and advanced genomic tools, we investigated whether these bacteria could serve as probiotics that support health.
We found that both strains can survive in acidic and bile-rich conditions similar to the human stomach and intestines, which is important for any probiotic. This means they have strong potential to be developed into health-promoting probiotics for food or medical use. Our work highlights how traditional Filipino foods can lead to scientific discoveries with real health benefits.
