Molecular Identification and Genetic Diversity of Acropora hyacinthus from Boo and Deer Island, Raja Ampat, West Papua
Indonesia lies at the centre of biodiversity for corals. However, the reefs suffered from
extensive human exploitation. Marine Protected Areas is thought to be best solution to protect
coral reefs ecosystem. Understanding genetic diversity is crucial for effective management of the
MPAs, however genetic diversity is rarely been corporate in designing an MPA. Moreover, many
MPAs are uneffectively manage due to poor designated and demarcated.Raja Ampat which is
located in western tip of West Papua, was designated as a park to mitigatethreatsand protect the
valuable marine resources.Scleractinian corals in the genus Acropora are among the most
dominant distributed in Raja Ampat waters, including the species of Acroporahyacinthus.The
research aimed to analyze genetic diversity and to describe the kinship relationship of
Acroporahyacinthus between 2 populations: Boo Island and Deer Island, Raja Ampat. Genetic
marker Cytochrome Oxidase I (CO I) of the mitochondrial genome DNA (mtDNA) was used to
analyze genetic diversity. Reconstruction of phylogenetic tree and genetic diversity were made
by usingsoftware MEGA 5.05 (Moleculer Evolutionary Genetics Analysis). The results of this
research indicatecorals A. hyacinthus from Boo Island and Deer Island Raja Ampat are in the
low category of genetic diversity and overall had a close genetic relationship of kinship. This is
likely due to the small size of the population and few numbers of samples that may not represent
the population
Isolation And Partial Characterization Of Bacteria Activity Associated With Gorgonian Euplexaura sp. Against Methicillin-Resistant Staphylococcus aureus (MRSA)
Methicillin-resistant Staphylococcus aureus (MRSA) infection has emerged in around the world and has been resistance to ciprofloxacin, erythromycin, clindamycin. The aims of this study were to isolate, to investigate and to characterize bacterial symbionts gorgonian having activity against MRSA. Euplexaura sp. was collected from Panjang Island, Jepara, Indonesia by snorkling 2-5 m in depth. Bacterias were isolated by using spesific media with dilution method. Bacterias were conducted by using the streak method. Antibacterial activity was investigated by overlay method. The potent bacteria was identified by using molecular identification (DNA extraction, electrophoresis, PCR and phylogenetic analysis using 16S rDNA genes with actinobacteria-spesific primers) and bio-chemical test (among 5 isolated bacteria from gorgonian showed activity against MRSA). The strain PG-344 was the best candidat that has an inhibition zone against MRSA. The result of sequencing bacteria is 100% closely related with Virgibacillus salarius. This becomes a potential new bioactive compounds to against MRSA that can be a new drug discovery
Analisis Kadar Etanol dalam Obat Batuk dengan Metode Kromatografi Cair
Etanol merupakan senyawa kimia yang umum digunakan sebagai pelarut dalam obat-obatan. Keberadaan etanol dalam obat dapat diragukan kehalalannya. Diperlukan analisa kandungan etanol dalam suatu produk. Kromatografi cair merupakan metode yang akurat untuk mengetahui keberadaan etanol dalam sampel. Penelitian ini bertujuan untuk menganalisa kandungan etanol dalam obat batuk menggunakan metode HPLC. Metode yang dilakukan terdiri dari persiapan standar etanol dan sampel obat batuk, serta analisa sampel dengan HPLC. Data hasil analisa diolah dengan menggunakan software Lab Solutions. Selanjutnya disusun kurva analitik dan persamaan linear. Hasil analisa menunjukkan sampel obat batuk jenis XXX memiliki kandungan senyawa etanol. Dari hasil yang diperoleh dapat disimpulkan bahwa metode HPLC tepat digunakan untuk menentukan kehalalan suatu produk
Isolation, Identification And Screening Antibacterial Activity from Marine Sponge-Associated Fungi Against Multidrug-Resistant (MDR) Escherichia coli
Irrational used of antibiotic in several decades ago causing resistant in bacteria and decreasing the cure rate of infectious diseases. Multidrug-resistant (MDR) Escherichia coli is known to cause several infectious diseases such as urinary tract infection, nosocomial bloodstream infection, meningitis, bacteraemia, and gastrointestinal disease. Marine sponge-associated fungi have potential as source of new compound to combat MDR E. coli. The aims of this research were to isolate marine sponge-assosiated fungi, to screen potential fungi against MDR E. coli, to identify the potential fungi and its host sponge. There were 29 marine sponge-associated fungi successfully isolated from 9 sponges. Among 29 sponge-associated fungi screened, there were 7 isolates showed antibacterial activity against MDR E. coli. The best inhibition zone produced by MPS 14.1/MT 02 and MPS 14.3/MT 04 from sponge PP.SP.16.14. According to fungi identification result fungus MPS 14.1/MT 02 was identified as Trichoderma asperellum while MPS 14.3/MT 04 was identified as Trichoderma reesei. Sponge identification leaded the PP.SP.16.14 as Cinachyrella sp
Exploration of Fungal Association From Hard Coral Against Pathogen MDR Staphylococcus haemolyticus
Staphylococcus haemolyticus are opportunistic bacteria and as the second leading
cause of nosocomial infections. It is a disease causing septicemia, peritonitis, otitis, and urinary
tract infections and infections of the eye. It also a phenotype resistant to multiple antibiotics
commercial. There is now an urgency to find an alternative antibiotics to combat this bacteria.
It has been widely reported that many bioactive marine natural products from marine
invertebrate have striking similarities to metabolites of their associated microorganisms
including fungi. Hard coral associated microorganisms are among of the most interesting and
promising marine natural product sources, which produce with various biological activities. The proposed work focused on the discovery of bioactive compounds and also estimated the phylogenetic diversity from fungal association of hard coral against pathogen MDR Staphylococcus haemolyticus. A total of 32 fungal association, FHP 7 which were isolated from Favia sp. capable of inhibiting the growth MDR. Molecular identification based on 18S rRNA gene sequences revealed that the active fungal association belonged 100% to the members fro

Biological activity of sponge-associated fungi from Karimunjawa Islands, Indonesia against pathogenic Streptococcus pneumoniae
Threats of drug-resistantStreptococcuspneumoniaeand the urgent need for new antibiotics require prompt and sustained action for discoveringbioactive compounds. This study aimed to isolate sponge-associated fungi as a candidate for sources of drugs. The sponge-associated fungi were screened against the MDR S. pneumoniae. The Deoxyribonucleic Acid(DNA) of fungal isolates that showed the most active was generated by using universal primers ITS1 and ITS4. While the sponge host was identified based on the molecular and by slide section. Out oftwenty-nine fungal isolates from 13 marine sponges, S.06.2isolate produced secondary metabolite that inhibiting the growth of MDR S. pneumoniae. Molecular identification based on the ITS region revealed that the active fungal isolate was closely related to Curvularia lunata, with a 99% similarity. The C. lunataS.06.2was isolated from sponge Cinachyrella australiensis. Thus, C. lunata S.06.2_ LC315806 can serve as a fruitful strategy for the discovery of novel antibiotics for the treatment of MDR S. pneumoniae
