A team of researchers from the University of the Philippines has identified a new bacterial species from the slopes of Mayon Volcano, a discovery that could help advance future research on antibiotics and other medical treatments.
The newly named Streptomyces mayonensis was isolated from volcanic soil collected in Malilipot, Albay. It belongs to the Streptomyces genus, a group of bacteria known for producing many of the antibiotics used around the world. The findings were published in 2025 in the International Journal of Systematic and Evolutionary Microbiology.
A Tiny Organism with Big Potential
The discovery builds on earlier research that found the bacterial strain possessed antibacterial and anticancer properties. Laboratory tests showed activity against several disease-causing microorganisms, including MRSA, Salmonella enterica, Klebsiella pneumoniae, and Candida albicans. It also demonstrated anticancer activity against human colorectal cancer cells.
To determine whether the organism was a previously unknown species, researchers conducted extensive physical, biochemical, and genomic analyses. The results confirmed that the microbe was genetically distinct from its closest known relatives, earning it recognition as a new species and the name Streptomyces mayonensis.
While scientists emphasize that more studies are needed before any practical applications can be developed, the formal identification of the species lays the groundwork for future research into its bioactive compounds.
Searching Nature for New Medicines
The discovery comes as the world faces growing concerns over antimicrobial resistance, a problem that occurs when bacteria evolve and become resistant to existing medicines.
Researchers note that Streptomyces species have long been a valuable source of antibiotics, accounting for many of the drugs used to treat bacterial infections today. This makes newly discovered members of the group particularly interesting to scientists searching for new compounds with medical potential.
For the UP team, the finding also highlights the value of exploring the Philippines' rich biodiversity. By studying microorganisms living in unique environments such as Mayon Volcano, researchers hope to uncover new species and compounds that could one day contribute to medicine, biotechnology, and other fields.
The discovery adds another Philippine species to the global scientific record and underscores the importance of supporting local research that could help address future health challenges.
