Abstract

Hepatitis C virus is the cause of hepatitis C disease which has high virulence. Recent therapy using combination of ribavirin and alpha interferon has short efficiency (< 80%). Thus, the discovery of new drug is needed. Antiviral drugs can be discovered through molecular target therapy by finding the inhibitor of RNA helicase that play role in viral replication. Inhibitor can be derived from chemical compound produced by mangrove. The aim of this research was to isolate the active compound groups from fruit of  Avicennia marina (Forsk) which had inhibitory activity against RNA helicase. Inhibitory activity was measured by releasing of phosphate inorganic in  colorimetric ATPase assay. Crude extract was fractionated using gel filtration chromatography with methanol in chloroform solvent. The result showed that fraction 2 has the highest inhibitory activity i.e. 81.78%. Phytochemical test of crude extract indicated positive result for flavonoids, alkaloids, steroid dan triterpenoid, tannin and saponins. Moreover, high performance liquid chromatography (HPLC) analysis showed absorption peak with the high abundance at the retention time of  7.250; 18.983 and 20.050 minute at 216 nm, 247 nm and 263 nm, respectively. According to the results of phytochemical, TLC, and HPLC analyses, inhibitor compound from fruit of  A. marina (Forsk) was suggested it belongs to flavonoids.Key words: Avicennia marina, flavonoid, hepatitis C virus, RNA helicase

Abstract

The diversity of lactic acid bacteria was evaluated from Indonesian fermented foods such as dadih (buffalo fermented milk), tempoyak (fermented durian), bekasam (fermented meat), and tape ketan (fermented glutinous rice). Lactic acid bacteria were enumerated using selective media and characterised based on a genotypic methods such as rep- PCR and RAPD-PCR, as well as 16S rRNA gene sequencing of representative strains. Forty-six colonies had successfullybeen isolated from Indonesian fermented foods. The great majority of these colonies originated from dadih (43.48%), tempoyak (39.13%), bekasam (13.04%) and tape (4,3%). The 46 isolates were characterised based on a genotypic methods such as RAPD and rep-PCR as well as 16S rRNA gene sequencing of representative strains. The rep-PCR result yielded seven clusters (I-VII) at a similarity level of 75-88% and RAPD-PCR used LB2 primer, M13 primer and primer A, B, C. The RAPD result using LB2 primer yielded eight clusters (I-VIII) at a similarity level of 82-91%. Identification using 16S rRNA showed that the majority strains as Lactobacillus plantarum, Lactobacillus fermentum and Pediococcus pentosaceus strains.

Abstract

Two quantitative traits, cherry and green bean characters are the important phenotypic selection in coffee breeding practice. The important well-known character from coffee markets is cherry and bean size. In this study, 43 genotypes of coffee were collected from four districts in East Kalimantan i.e. Kutai Kertanegara, Kutai Timur, Berau dan Paser Utara. The objective of this study was to identify cherry and green bean character using quantitative trait locus (QTL) molecular marker, genetic variation from developed alleles, cluster analysis and association analysis of molecular marker, and phenotype observation. Based on polymorphic information content (PIC) of primers used in this study, the genetic variation was low. Based on cluster analysis, two major groups were identified. The first group corresponds to Arabika that consisted of 3 districts, Kutai Timur, Berau and Paser Utara. The second group correspond to Robusta mostly from Kutai Kertanegara.Significant association of primer markers M480 and M312 with QTL has suggested that they can be used as specific primers linked to size of cherry and green bean.Furthermore,they were potential marker assisted breeding in coffee breeding program.

Abstract

Xanthomonas oryzae pv. oryzae (Xoo) is the bacterial causative agent of leaf blight in rice (Oryza sativa L.), the most serious bacterial disease of rice in many rice growing areas worldwide. This study aimed to identify and characterize several virulence factors of seven Xoo isolates from Yogyakarta, West Java, and West Sumatera. The identification of Xoo using 16S rRNA confirmed high homology to Xanthomonas oryzae pv. oryzae PXO99A and revealed three groups. The first group was Xoo93229, the second group containing Xoo1110, Xoo1122, Xoo1130, Xoo7624 and Xoo8024 as the same cluster with PXO99A and the third group was KACC10331 and MAFF311018. The amounts of exopolysaccharide (EPS) and cellulase produced were varying depending on the Xoo isolates. The EPS were produced more by isolate Xoo1130, Xoo1122 and Xoo8024. All tested isolates revealed similar cellulase activity except for isolate Xoo8024. The pathogenicity assay among the Xoo isolate showed that all tested isolates were virulent except Xoo7624. The in planta assay revealed that the tested isolates have multiplied and continued increasing the population size except for Xoo1110 and Xoo7624. High yield of EPS, cellulase activity, more virulence, and increasing population size revealed from isolate Xoo1130 and Xoo1122.

Abstract

Lactobacillus plantarum U10 produced bacteriocin U10 which was isolated from a traditionally fermented food “tempoyak” from Sumatera Island in Indonesia. Production of the bacteriocins started at early exponential phase and reached maximum level at early stationary phase. Furthermore, plantaricins U10 was purified by ammonium sulphate precipitation followed by gel filtration chromatography. L. plantarum U10 produced two bacteriocins with a molecular mass of approximately 4.5 and 9.8 kDa by SDS-PAGE.  The mode of action of plantaricins U10 was identified as bactericidal agents against Salmonella typhi ATCC25241 as proven by CFU counting and SEM micrographs that showed differences in cell structures between treated cells and the non-treated control. SEM examination also confirmed structural destruction of membrane cells integrity and considerable morphological alteration of S.typhi.

Abstract

Indonesia kaya akan keanekargaman tanaman obat. Salah satunya adalah rimpang kencur atau Kaempferia galanga L. Tanaman ini memiliki potensi besar sebagai sumber penting senyawa bioaktif yang dapat mendukung pengembangan obat-obatan alami serta mendorong penelitian lebih lanjut dalam bidang farmakologi dan pengobatan. Kaempferia galanga sendiri telah diteliti mengandung beragam senyawa yang dapat dimanfaatkan untuk berbagai aktivitas farmakologi salah satunya adalah antikanker. Salah satu komponen senyawa yang dimiliki oleh Kaempferia galanga  yang dapat digunakan sebagai antikanker adalah etil p-methoxycinnamate (EPMC). Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi senyawa EPMC untuk memperoleh hasil isolasi yang maksimal dengan kadar EPMC yang tinggi. Metode isolasi EPMC dari tanaman kencur menggunakan soxhlet sebagai alat ekstraksi. Identifikasi dan penentuan kadar senyawa diperoleh menggunakan evaluasi KLT, GC-MS, NMR, HPLC dan Spektrofotometri UV-Vis. Hasil identifikasi menunjukkan isolat dari Kaempheria galanga merupakan senyawa ethyl p-methoxycinnamate dengan berat molekul 206 dan persentase kadar EPMC menunjukkan kadar yang tinggi baik menggunakan HPLC  maupun spektrofotometer UV-Vis, dimana kadar EPMC dalam isolat didapatkan sebesar 90,40 ± 3,62 %, dan 91,29 ± 3,66 %. Sedangkan untuk kadar pada ekstrak metanol Kaempheria galanga adalah 49,57 ± 0,63 % dan 40,61± 0,25% berdasarkan hasil HPLC dan spektrofotometer UV-Vis.  Berdasarkan hasil tersebut dapat disimpulkan bahwa metode isolasi EPMC dari tanaman kencur (Kaempferia galanga) menggunakan soxhlet sebagai alat ekstraksi memberikan rendemen ekstrak dan rendemen isolat yang tinggi.

Abstract

Xanthomonas oryzae pv. Oryzae (Xoo) is the causal agent of bacterial blight in rice (Oryza sativa L.). In the understanding of virulence determinants of three Indonesian Xoo, extracellular polysaccharide (EPS) production, cellulose and diffusible signal factor (DSF) were identified. DSF signaling system in Xoo is involved in the regulation of virulence factor production. In this study the comparative analysis was conducted with the DSF biosensor isolate (Xoo-dsf). The results showed that high yield of EPS and cellulose activity revealed from isolate Xoo1130 and Xoo1122 compare to Xoo93229 while Xoo-dsf giving similar result with Xoo1130. The comparative analysis of Xoo1130 and Xoo-dsf showed that Xoo1130 produced three DSF-family signals (DSF, BDSF and CDSF) similar to the DSF biosensor isolate. It assumed that Xoo1130 uses a similar mechanism in Xoo-dsf to autoregulate the biosynthesis of the DSF-family signals.
