A marine bacterium collected in Romblon is part of a Filipino antibiotic research project that has secured Philippine patent protection.
The University of San Agustin announced the patent in April 2026. It said the patent had been granted on February 6 and described it as the university’s fourth Philippine patent.
The underlying laboratory study examined a strain of Streptomyces griseorubens isolated from marine sediment collected in Romblon. Compounds associated with the strain showed antibacterial activity against a multidrug-resistant strain of Staphylococcus aureus.
The work places Philippine marine biodiversity within locally led drug-discovery research: researchers isolated the bacterium, studied the substances it produced and investigated their activity in the laboratory.
Patent protection covers an invention. It does not establish that the compounds are safe or effective medicines for people.
The researchers identified toxicity and molecular targets as areas requiring further investigation. The compounds therefore remain antibiotic leads for continued research.
The achievement is a step in a longer scientific process, with Philippine researchers and marine resources contributing to the search for potential new antibiotics.
