Abstract

Nyatoh plant (Palaquium amboinense B.) is native to Indonesia which is known to have the ability to produce potential secondary metabolites. The aim of this study was to evaluate the antibacterial and antioxidant activities from bioactive compounds produced by endophytic bacteria from nyatoh leaves. Five endophytic bacteria were tested against 4 targeted bacteria including Escherichia coli ATCC 8739, Pseudomonas aeruginosa ATCC 15442, Bacillus subtilis ATCC 19659, and Staphylococcus aureus ATCC 6538. Bacterial isolate which had the strongest antibacterial activity was then fermented and extracted. The corresponding extract was further tested on disc diffusion method, determination of Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) values, antioxidant evaluation, and analyzed for its bioactive compound components via GC-MS analysis. The results showed that one isolate, namely D1 can produce secondary metabolite which act as antibacterial and antioxidant potentials. This corresponding extract has the strongest MIC and MBC against B. subtilis with value of 39.5 and >78.1 µg/ml and exhibited antioxidant activity against 2,2-difenil-1-pikrilhidrazil (DPPH) with inhibition value of 85.37%. Based on GC-MS analysis, secondary metabolites derived from this potential extract contained some major active constituents including Tributyl acetylcitrate and bis (2-ethylhexyl) ester which might act as antibacterial and antioxidant agents.

Abstract

Health Care Associated Infection (HCAI) is one of the global infectious diseases that is expected to cause around 10 million deaths by 2050. One of the main causes is biofilm, an exopolysaccharide layer formed by bacteria, often found on medical equipment such as catheters, and has high resistance to antibiotics. Prevention efforts can be made through the search for antibiofilm compounds. Actinobacteria are known to produce potential bioactive compounds. This study utilized Actinobacteria strains from the waters of Bitung, North Sulawesi (code BT-023-026) to explore their antibiofilm potential through isolation, laboratory tests, and genetic analysis, followed by expert confirmation in the fields of intelligence, BPOM, and microbiology. The results show the great potential of BT-023-026 as an antibiofilm agent to prevent antibiotic resistance due to HCAI, while playing a strategic role in biodefense and strengthening health security through early warning and early detection.
