Pathogenic bacteria Klebsiella pneumoniae is the cause of pneumonia disease in infants and adults. Antibiotics treatment is usually used to treat this disease. However, synthetic antibiotic use could lead to bacterial resistance. Therefore, novel antibiotics from natural resources are required to overcome this problem. The aim of present study is to determine the antibacterial activity of endophytic fungal extracts from mangrove plants Rhizophora apiculata and Bruguiera gymnorrhiza against K. pneumonia ATCC 700 603. Isolation, cultivation, extraction and antibacterial activity test were conducted. Fourteen endophytic fungi were derived from the two mangrove species, where the two fungal isolates: Penicilium sp.2 and Penicilium sp.4 showed the highest antibacterial activity. The minimum inhibitory concentration of K. pneumoniae for both fungal extract is 3.6 mg mL-1, where bactericidal effect was observed. Additionally, antibacterial activity from the extract of Penncillium sp.4 is higher compared to Penicilium sp.2 extract, which is signified by larger average diameter of inhibition zone. However, at concentration more than 3.6 mg mL-1, both extract effectively inhibit the growth of K. pneumoniae. Our study reveals the potential of fungal extract from mangrove plant as prospective drug candidate to overcome the pneumonia disease. Keywords: antibacterial, pneumonia, endophytic fungi, mangrove

A total of 17 endophytic fungal isolates were obtained from the leaves of Mentha cordifolia Opiz (Lamiaceae). Seven isolates were identified to the level of genus by using taxonomically relevant morphological traits. Colletotrichum and Phomopsis species were dominant among these strains. All strains were separated from M. cordifolia leaf for the first time. The ethyl acetate extracts of all endophytic fungi were tested for antibacterial activity against Salmonella typhimurium TISTR1166 and Pseudomonas aeruginosa TISTR781. Most endophytes exhibited antibacterial activity. Ustilago sp. MFLUCC15-1024 presented the highest inhibition zone diameter with a MIC of 31.25 μg/mL against the tested pathogens. The chemical composition of the ethyl acetate extract of this strain was investigated using gas chromatography-mass spectrometry. Twenty-one components were identified. 2-Phenylethanol (38.7%), E-ligustilide (12.4%), α-eudesmol (10.2%), β-vetivone (4.6%), β-ylangene (3.7%) and verbanol (3.4%) were the major components of the extract. The strong antibacterial activity of Ustilago sp. MFLUCC15-1024 ethyl acetate extract may be attributed to the presence of a high concentration of bioactive compounds including phenyl ethyl alcohol, E-ligustilide and α-eudesmol. The results indicate that there is high diversity of endophytic fungi in M. cordifolia leaf, and that Ustilago sp. MFLUCC15-1024 strain could be an excellent resource of natural antibacterial compounds.
