This study aims to determine the activity of marine pandanus extract(Pandanus odorifer) as cytotoxic and antibacterial to Staphylococcus aureus bacteria. This research begins with phytochemical test conducted to find out the secondary metabolite compounds contained in the leaves of P. odorifer. Cytotoxic testing was performed using BSLT method. An antibacterial test was performed against the activity in inhibiting the growth of S. aureus bacteria using a modified disc diffusion method. The results of phytochemical tests showed that ethanol extract of pandanus leaves contain saponin, flavonoids, tannin and terpenoid compounds. The results of cytotoxic test of sea pandan have a very strong toxic level with LC50 value of 4.3557 ppm.The result of measurement of the highest inhibiting zone diameter was obtained at the concentration of 5x104 ppm is 6 mm with the power of inhibitory that is medium. Based on the results of this study can be concluded that the leaves of sea pandan are cytotoxic and have activity as antibacterial

Meticillin-resistant Staphylococcus aureus isolates were classified into three mupirocin susceptibility groups by the disc diffusion method using 5 and 200 μg mupirocin discs. The zone diameter observed for a 5 μg disc distinguished MupS from the resistant strains (either MupRL or MupRH). On the other hand, a 200 μg disc distinguished the high-resistance MupRH strains from the other two (MupS or MupRL). Thus, the concomitant use of 5 and 200 μg mupirocin discs allowed the clear distinction among the three mupirocin susceptibility groups, MupS, MupRL or MupRH.

ABSTRAKStaphylococcus aureus merupakan bakteri yang relatif sering dijumpai pada manusia. Beberapa infeksi yang disebabkan oleh Staphylococcus aureus antara lain, bisul, infeksi luka dan pneumonia. Salah satu obattradisional yang dapat digunakan untuk mengobati infeksi yang disebabkan oleh Staphylococcus aureus adalah jamur lingzhi (Ganoderma lucidum). Penelitian dilakukan dengan 5 konsentrasi ekstrak etanol jamur lingzhi, yaitu kontrol negatif (0 µg/ml), 20 µg/ml, 40 µg/ml, 60 µg/ml, 80 µg/ml dan 100 µg/ml dan dilakukan 6 kali pengulangan. Metode yang digunakan dalam uji aktivitas antimikroba yaitu metode difusi kertas cakram. Data zona hambat dianalisis dengan uji Anova One-Way. Hasil penelitian menunjukkan bahwa ekstrak etanol jamurlingzhi (Ganoderma lucidum) dengan konsentrasi 100 µg/ml memiliki rata-rata daya hambat tertinggi yaitu sebesar 18,0 mm (sangat aktif). Dapat disimpulkan bahwa semakin besar konsentrasi ekstrak jamur lingzhi (Ganoderma lucidum), maka akan berpengaruh besar pula terhadap zona hambat bakteri Staphylococcus aureus.Keyword : Antibakteri, Ganoderma lucidum, Staphylococcus aureus, Etanol.ABSTRACTStaphylococcus aureus is a bacteria that can cause infections , such as boils , wound infections and pneumonia. One of the traditional medicines that can be used to treat these infections are fungal lingzhi (Ganodermalucidum). The study was conducted with five concentrations of negative control (0 µg/ml), 20 µg/ml, 40 µg/ml, 60 µg/ml, 80 µg/ml, and 100 µg/ml with six repeats. The method used in the test of antimicrobial activity is paper disc diffusion method. Data of inhibition zone were analyzed by Anova-One Way test. The results showed that the ethanol extract of lingzhi mushroom (Ganoderma lucidum) at concentration 100 µg/ml has highest average of inhibitory regions as big as 18,0 mm. It can be concluded that the greater the concentration of extract of lingzhi mushroom (Ganoderma lucidum) , it will affect the greater the inhibition zone against Staphylococcus aureus.Keyword : Antibakteri, Ganoderma lucidum, Staphylococcus aureus, Etanol.

AbstractMarine sponges are known for their antimicrobial, antifungal, and cytotoxic activity. In this study, the activity of aqueous and ethanoic extracts of 3 sponges from Martinique were tested on 5 bacterial strains: Bascillus cereus (CIP 783), Echerichia coli (CIP 54127), Pseudomonas aeruginosa (CIP A22), Staphylococcus aureus (CIP 67.8) and Staphylococcus saprophyticus (CIP 76125). The antimicrobial activity of Agelas clathrodes, Desmapsamma anchorata, and Verongula rigida, was demonstrated using the disc diffusion method and by determining the minimum inhibitory concentration and the minimum bactericidal concentration. The ethanoic extract of Agelas clathrodes had an inhibitory activity specifically on Staphylococcus aureus and Staphylococcus saprophyticus. No activity was observed for the other extracts. Further chemical analyses will be carried out in order to identify the active molecules of these sponges.

Study Design: Structural determination of the isolated compound was done using spectral evidences and in comparison with literature. The antibacterial properties of the compound was done using disc diffusion method. Place and Duration of Study: Department of Pure and Applied Chemistry, Masinde Muliro University of Science and Technology, between January and November, 2019. Methodology: Sequential extraction of dried samples of Kenyan G. lucidum were done using solvents hexane, ethyl acetate and methanol. Chromatographic separation of hexane extract of Ganoderma lucidum was done using spectroscopic data. The compound was assayed against Escherichia coli, Klebsiella pneumoniae, Methicillin–Resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa and Streptococcus pyogenes. Standard antibiotic namely; ampicillin was used as the control. Disc diffusion method was used and zones of inhibition, after respective incubation periods, were used to quantify antibacterial activity. Results: From hexane extract of Ganoderma lucidum, Ergosta-5, 7, 22-triene-3β, 14α – diol (22Z) was isolated. Ethylacetate and methanol extracts produced a mixture of complex compounds. Ergosta-5,7,22-triene-3β,14α-diol (22Z) exhibited significant activity against Methicillin-Resistance Staphylococcus aureus (MRSA) (p=0.022) and Streptococcus pyogenes (p = 0.05). The most sensitive microbe was Streptococcus pyogenes. Conclusion: One major compound, Ergosta-5, 7, 22-triene-3β, 14α – diol (22Z) was isolated, characterized and antibacterial activity determined.
