Abstract

Telah dilakukan analisis kualitatif dan kuantitatif asam lemak tak jenuh Omega-3 dan Omega-6pada minyak ikan patin (Pangasius pangasius) dengan menggunakan metode kromatografi gas. Kadar Omega-3yang diperoleh dari minyak ikan patin yaitu berkisar antara 1,16-12,44(%W/W) dan kadar Omega-6 berkisaranantara 12,278-15,961(%W/W). Dari kadar Omega-3 dan dari kadar Omega-6 yang diperoleh dari penelitianini, ikan patin dapat digunakan sebagai sumber Omega-3 dan Omega-6 alternatif. Dalam penelitian ini jugadilakukan karakterisasi minyak ikan patin yang meliputi kadar minyak, bilangan asam, bilangan penyabunan,dan bilangan peroksida dengan metode Badan Standarisasi Nasional. Dari hasil penelitian pada ikan patindengan berat 650-879 gram diperoleh kadar minyak rata-rata 3,827(%W/W), bilangan asam berkisar antara3,667-19,521 mgKOH/gr, bilangan penyabunan berkisar antara91,319-192,656 mg KOH/gr, dan bilangan peroksida berkisar antara 0,778-17,78 mek/kg.

Abstract

Bakteri termo-lipolitik merupakan bakteri pendegradasi lipid yang mampu beraktivitas pada suhu tinggi. Bakteri tersebut memiliki peran penting dalam perkembangan bioteknologi pada saat ini, karena dapat diaplikasikan pada berbagai industri baik industri pangan maupun non pangan.  Salah satu upaya yang dilakukan pada penelitian ini adalah mencari dan menyeleksi isolat-isolat bakteri termofilik yang memiliki aktivitas lipolitik, serta mengetahui jenis dari masing-masing isolat tersebut. Seleksi dilakukan pada medium ZoBell padat yang mengandung olive oil 1% dengan menggunakan metode pour plate dan identifikasi isolat melalui analisis sekuen gen 16S-rRNA menggunakan DNA sequencer.  Hasil isolasi memperoleh 6 isolat bakteri termofilik, dan hanya 4 isolat yang memiliki aktivitas lipolitik dengan indeks lipolitik tertinggi 2,65.  Analisis similaritas berdasarkan sekuen gen 16S-rRNA menunjukkan bahwa dari isolat bakteri termo-lipolitik pada penelitian ini memiliki kemiripan dengan Anoxybacillus pushchinoensis 99% (untuk isolat AA1 dan AA3), Anoxybacillus sp. 99% (untuk isolat AB2) dan Bacillus licheniformis 99% (untuk isolat LB1).

Abstract

A community of thermophiles within Tanjung Sakti Hot Spring (South Sumatera) have been cultivated and identified based on 16S ribosomal RNA gene sequence. The hot spring has temperature 80C-91C and pH 7-8. We used a simple method for culturing the microbes, by enriching the spring water with nutrient broth media. Phylogenetic analysis showed that the method could recover microbes, which clustered within four distinct taxonomic groups: Anoxybacillus, Geobacillus, Brevibacillus, and Bacillus. These microbes closely related to Anoxybacillus rupiensis, Anoxybacillus flavithermus, Geobacillus pallidus, Brevibacillus thermoruber, Bacillus licheniformis, and Bacillus thermoamylovorans. The 16S ribosomal RNA gene sequence of one isolate only had 96% similarity with Brevibacillus sequence in GenBank.

Abstract

Medicinal plants and their endophytes are important resources for discovery of natural products. Endophytic fungi isolated from medicinal plants more likely exibit pharmaceutical potentials. In the present study, an endophytic fungus Aspergillus sp (SbD5) was isolated from leaves of sambiloto (Andrographis paniculata). The fungus isolate was cultivated in Potato Dextrose Broth (PDB) medium for 7 weeks in static, then extracted with ethyl acetate followed by Thin Layer Chromatography (TLC) test. The results displayed three major spots. Ethyl acetate extract was further separated by column chromatography and recrystallization to obtain three pure compounds. Their structures were determined on the basic of spectroscopic analysis. The compounds is one new benzochromen derivative, 1-(3,8-dihydroxy-4,6,6-trimethyl-6H- benzochromen-2-yloxy)propan-2-one (1), together with two known compounds 5-hydroxy-4-(hydroxymethyl)-2H-pyran-2-one (2) and (5-hydroxy-2-oxo-2H-pyran-4-yl)methyl acetate (3). The antibacterial activities of the compounds were tested using the disk diffusion method against Staphylococcus aureus (ATCC 25923), Escherichia coli (ATCC 25922), Shigella dysenteriae and Salmonella typhi.  Compound 1 has the highest antibacterial activity followed by compound 2 and 3.

Abstract

Flacourtia  rukam is a plant popular among people to treat hypertension, especially the Musi Banyuasin of south Sumatera, Indonesia. Isolation and identification of chemical compounds from F. rukam leaves and evaluation of their effects on antihypertensive activity have been conducted. Isolation of chemical compounds using chromatographic methods and identification using spectroscopic methods were compared with the reported data. The drug’s effects on antihypertension were determined using the  angiotensin converting enzyme (ACE) inhibitory method. Two compounds were first reported and isolated from the leaves of F. rukam and identified as apigenin (1) and lupeol (2). These compounds were demonstrated to be effective in treating antihypertension with IC50 656.51 ± 1.55 µg/mL for apigenin and 15.12 ± 0.72 µg/mL for lupeol. It can be concluded that  F. rukam leaves is a potential ACE inhibitor can be explored further as an effective antihypertensive agent.

Optimization conditions for thermostable xylanase production of Bacillus licheniformis TS10 by using substrate oil palm empty fruit bunches  has been conducted from November 2015 to January 2016 in the Laboratory of Genetics and Biotechnology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Sriwijaya, Indralaya. The aims of this study was to determine the potential of oil palm empty fruit bunches ( EFB ) as a substrate for the production of thermostable xylanase by Bacillus licheniformis TS10 and the optimum conditions of temperature, pH and substrate concentration in the fermentation process. The research method is to make the growth curve and the curve of Bacillus licheniformis TS10 enzyme production on EFB substrate. The number of bacterial cells was determined by using a UV-VIS spectrophotometer and total plate count (TPC) through a standard curve. Optimization performed at various pH (5, 6, 7, 8, 9), temperature (50 °C, 60 °C, 70 °C, 80 °C) and substrate (1%, 2%, 3%, 4%) , Test activity at each pH, temperature and substrate using methods DNS by measuring enzyme activity based on the reducing sugar released by the substrate by using dinitrosalicylic acid (DNS). Based on the results of this research showed that oil palm empty fruit bunches (EFB ) has potential as a substrate for the production of thermostable xylanase by Bacillus licheniformis TS10, thermostable xylanase production of Bacillus licheniformis TS10 on the substrate EFB has an optimum condition at pH 6, 80 °C and the substrate concentration of 4%.
