After the Phase 1 (Dec. 2016- Nov. 2017) and Phase 2 (Dec. 2017- Nov. 2018) of the research program entitled "Marine Sediment-Derived Actinobacteria: New Vista for Natural Products Discovery on the Philippines", a total of 3,371 actinobacteria strains were recovered from marine sediment samples collected in 21 sampling sites in the Philippine archipelago. After screening for their antibacterial activities against pathogenic Gram-positive and Gram-negative bacteria, 169 active strains have confirmed antibacterial activities with at least 50% growth inhibition gainst the test bacteria.
