Abstract

Ethanol is an important product for biotechnology-based industries. Ethanol can be produced from various raw materials and some types of microbes. Determination of the best combination of galactose with nitrogen sources on ethanol production using Saccharomyces cerevisiae has been done. Combination of galactose at the concentration of 3 g/L and 20 g/L with nitrogen sources (casein, peptone, and urea, each at the concentration of 10g/L) was used to obtain the best composition of fermentation medium. Fermentation was carried out for 60 hours at 30°C, 250 rpm, and working volume of 50 mL in a 250 mL erlenmeyer. The results showed that the galactose concentration of 20 g/L was able to improve the productivity of ethanol and the growth of S. cerevisiae cells. The combination of 20g/L galactose and 10 g/L casein produced the highest ethanol concentration (6% v/v), whereas 20 g/L galactose-10 g/L peptone and 20 g/L galactose-10 g/L urea combinations produced 2.5% and 0.58% (v/v) ethanol, respectively. The use of 3 g/L galactose mixed with several nitrogen sources produced ethanol below 0.7% (v/v). Keywords: Ethanol, galactose, peptone, casein, Saccharomyces cerevisiaeABSTRAKEtanol merupakan salah satu produk penting bagi industri yang berbasis bioteknologi. Etanol dapat dihasilkan dari berbagai macam bahan baku dan beberapa jenis mikroba. Penentuan kombinasi terbaik antara galaktosa dengan sumber nitrogen pada produksi etanol menggunakan Saccharomyces cerevisiae telah dilakukan. Konsentrasi galaktosa 3 g/L dan galaktosa 20 g/L yang dikombinasikan dengan sumber nitrogen dengan konsentrasi 10 g/L dalam hal ini kasein, pepton, dan urea digunakan sebagai perlakuan untuk mendapatkan kombinasi medium sumber karbon dan sumber nitrogen terbaik. Fermentasi untuk menghasilkan etanol dilakukan selama 60 jam pada suhu 30°C, agitasi 250 rpm dengan volume kerja 50 mL dalam erlenmeyer 250 mL. Hasil penelitian menunjukkan penambahan galaktosa dengan konsentrasi sampai dengan 20 g/L mampu memperbaiki produktivitas etanol dan pertumbuhan sel S. cerevisiae. Konsentrasi 20 g/L galaktosa dengan 10 g/L kasein menghasilkan produktivitas etanol paling tinggi yaitu 6%(v/v), konsentrasi galaktosa 20 g/L dengan 10 g/L pepton menghasilkan 2,5% (v/v) etanol dan konsentrasi galaktosa 20 g/L dengan 10 g/L urea menghasilkan 0,58%(v/v) etanol. Penggunaan konsentrasi galaktosa 3 g/L yang dikombinasikan dengan beberapa jenis sumber nitrogen menghasilkan etanol dibawah 0,7% (v/v).Kata kunci: Etanol, galaktosa, pepton, kasein, Saccharomyces cerevisiae

Abstract

Pohon sagu (Metroxylon sagu Rottb.) mempunyai banyak keunggulan dibanding dengan tanaman-tanaman penghasil pati lainnya, khususnya karena memiliki produktivitas yang tinggi, tumbuh di area bantaran sungai dan rawa, yang merupakan lingkungan tidak sesuai bagi pertumbuhan tanaman-tanaman lain. Dalam rangka membangun suatu perkebunan sagu di area yang luas, maka sangat dibutuhkan anakan-anakan sagu yang ukurannya seragam dalam jumlah yang besar. Namun demikian, terbatasnya jumlah anakan yang seragam telah menjadi kendala bagi pengembangan perkebunan sagu. Sebagai alternatif, perbanyakan in vitro dengan induksi tunas langsung dilakukan untuk mendapatkan bibit-bibit sagu dengan genotip unggul secara masal. Anakan sagu yang diperoleh dari Propinsi Maluku digunakan sebagai sumber eksplan. Eksplan dikultur pada media MS dan B5 yang mengandung kombinasi hormon auksin dan sitokinin. Hasil penelitian menunjukkan bahwa perlakuan BAP 2.0 ppm dan NAA 2.0 ppm menghasilkan jumlah tunas terbanyak.Kata kunci: Auksin, sitokinin, in vitro, sagu, inisiasi tunas ABSTRACTSago palm (Metroxylon sagu Rottb.) has many advantages over other starch-producing crops especially for its higher yield, ability to grow along riverbanks and on swampy areas not suitable for other crops. With the purpose of establishing large-scale plantations, a large amount of uniform sago palm suckers are required. However, limited availability of uniform suckers has hindered the mass propagation and development of cultivated Sago palm. Alternatively, in vitro cultures were performed in order to obtain a large-scale of mass clonally propagation of superior genotypes of sago palm. The young suckers obtained from areas of Maluku Province were used as explants. In vitro culture was carried out through direct shooting. The explants were cultured on two kinds of media, which were MS and B5 media containing various growth hormones of auxins and cytokinins. The results showed that the treatment with BAP 2.0 ppm and NAA 2.0 ppm produced the highest number of shoots.Keywords: Auxin, cytokinin, in vitro, sago palm, shoot initiation

Abstract

A blood clot (thrombus) in a blood stream is formed due to a circulatory system imbalance in the hemostasis which results in plug of blood vessels. The suppliy of nutrients and oxygen to the tissues is inhibited (ischemia) by the accumulation of thrombus and embolus in the blood vessel. This prosses is the main cause for further atherotrombotic diseases such as myocardial infraction and cerebral infraction. This disease could be overcome by thrombolytic therapy by using fibrinolytic protease enzyme. Fibrinolytic activity of protease enzymes have been studied from various species of bacteria. Bacterial isolate of WU 021055* obtained from Papuma coastal waters has demonstrated fibrinolytic activity. This research was aimed to identify the bacterial isolate through morphological characterization (colony and cell morphology), physiological characterization (indole test, carbohydrates fermentation test (glucose, lactose, sucrose and fructose), catalase test, starch hydrolysis test, and the pH effect test), and molecular identification using 16S rRNA. Based on those characterizations, the bacterial isolate of WU 021055* shows a high similarity to Bacillus aerius.Keywords: Atherotrombosis, fibrinolytic, identification, characterization, bacteria ABSTRAKBekuan darah (trombus) dalam peredaran darah terbentuk akibat ketidakseimbangan sistem sirkulasi dalam hemostasis yang menyebabkan penyumbatan pembuluh darah. Akumulasi trombus dan embolus pada pembuluh darah mengakibatkan suplai nutrisi dan oksigen ke jaringan terhambat (iskemia) dan bahkan kematian jaringan (infark). Pembentukan ini merupakan etiologi dari penyakit aterotrombosis seperti infark miokard dan infark serebral. Penyakit akibat trombosis ini dapat diatasi dengan terapi trombolitik dengan enzim protease fibrinolitik. Aktivitas enzim protease fibrinolitik telah diteliti dari berbagai spesies bakteri. Isolat bakteri WU 021055* asal perairan pantai papuma tampak memiliki aktivitas fibrinolitik. Pada penelitian ini dilakukan identifikasi isolat bakteri melalui karakterisasi morfologi (morfologi koloni dan sel), karakterisasi fisiologis (uji indol, uji fermentasi karbohidrat (glukosa, laktosa, sukrosa dan fruktosa), uji katalase, uji hidrolisis pati, dan uji pengaruh pH), dan identifikasi secara molekuler menggunakan 16S rRNA. Berdasarkan karakterisasi morfologi, fisiologi, dan marker 16S rRNA, isolat bakteri WU 021055* menunjukkan kemiripan yang tinggi dengan Bacillus aerius.Kata kunci: Aterotrombosis, fibrinolitik, identifikasi, karakterisasi, bakteri

Abstract

Sambiloto (Andrographis paniculata) banyak digunakan untuk mengobati berbagai penyakit di Indonesia dan negara-negara Asia lainnya. Dalam studi ini, ekstrak metanol dan etanol sambiloto yang diperoleh dari B2PTO Tawangmangu telah diuji terhadap sel lini kanker payudara T47D dan MCF-7 dan sel lini normal fibroblast HFL-1 menggunakan reaksi enzimatik 3-(4,5-dimethylthiazoyl-2-yl) 2,5-diphenyltetrazoliumbromide (MTT). Uji in vitro terhadap sel lini normal fibroblast HFL-1 menunjukkan bahwa 50 ppm ekstrak metanol sambiloto tidak menghambat pertumbuhan sel. Tetapi, ekstrak metanol dan etanolnya menghasilkan IC50 yang relatif rendah pada sel lini kanker payudara, yaitu 111 ppm dan 122 ppm pada sel lini MCF-7 dan 70 ppm dan 197 ppm pada sel lini T47D. Selain itu, campuran ekstrak sambiloto yang mengandung 25% ekstrak Thyponium divaricatum dan Anredera cordifolia memberikan daya hambat pertumbuhan pada sel kanker payudara MCF-7 yang lebih besar, dengan nilai IC50 masing-masing adalah 68 ppm dan 34 ppm. Kesimpulannya, total ekstrak metanol atau etanol sambiloto yang diperoleh dari Tawangmangu memiliki potensi sebagai sumber senyawa anti-kanker serta perlu kajian lebih lanjut.Kata kunci: Ekstrak Andrographis paniculata, MTT, sel lini normal, sel lini kanker, aktivitas anti kanker ABSTRACTSambiloto (Andrographis paniculata) is widely used as medicine to treat various diseases in Indonesia and other Asian countries. In this study, methanolic and ethanolic extracts of sambiloto collected from B2PTO Tawangmangu have been tested againts breast cancer cell lines of T47D and MCF-7 and normal fibroblast cell line of HFL-1 using enzymatic reaction of 3-(4,5-dimethylthiazoyl-2-yl) 2,5-diphenyltetrazoliumbromide (MTT). In vitro assay performed on normal fibroblast of HFL-1 cell line showed that 50 ppm of methanolic extract of sambiloto did not inhibit cell growth. However, methanolic and ethanolic extracts of sambiloto gave relatively low of IC50 on breast cancer cell lines which were 111 ppm and 122 ppm on the MCF-7 cell lines and 70 ppm and 197 ppm on the T47D cell lines, respectively. In addition, the mixture of sambiloto extract containing 25% of Thyponium divaricatum and Anredera cordifolia extracts confered greater growth inhibition on breast cancer cell line of MCF-7, where IC50 values were 68 ppm and 34 ppm, respectively. In conclusion, the total methanolic or ethanolic extract of sambiloto collected from Tawangmangu has potency as a source of anti-cancer compounds and needs further study.Key words: Andrographis paniculata extract, MTT, normal cell line, cancer cell lines, anti-cancer activity

Abstract

Chemical compounds belonging to dioxin group are known to be highly toxic environmental pollutant. Polychlorinated dibenzo-p-dioxin and polychlorinated dibenzofuran are produced during organic materials burning process. Pentachlorophenol, a compound similar to dioxin, is widely used as wood preservative, fungicide, bacteriocide, herbicide, algicide and insecticide. Some white-rot fungi have potential to produce lignin degrading enzyme and degrade dioxin compounds. The diversity of white-rot fungi in Indonesia provides potential source for environmental pollutant-degrading microorganisms. In this study, basidiomycetes were isolated from fruiting body and rotted wood samples which were collected from seven provinces in Indonesia. Three hundred seventy basidiomycete isolates were screened for dioxin degrading activity using dye-decolorization method. The result indicated that sixty isolates had dioxin degrading activity, three of which showed significant activity.Keywords: Ligninolytic, basidiomycetes, biodegradation, dioxin, fungus ABSTRAKSenyawa-senyawa kimia dalam kelompok dioksin telah diketahui sebagai polutan lingkungan yang sangat beracun. Dibenzo-p-dioksin terpoliklorinasi dan dibenzofuran terpoliklorinasi dihasilkan selama proses pembakaran bahan-bahan organik. Pentaklorofenol, suatu senyawa mirip dioksin, banyak digunakan sebagai pengawet kayu, fungisida, bakterisida, herbisida, algisida dan insektisida. Beberapa jamur pelapuk putih memiliki potensi untuk menghasilkan enzim pengurai lignin dan mendegradasi senyawa-senyawa dioksin. Keanekaragaman jamur pelapuk putih di Indonesia yang tinggi merupakan sumber potensial mikroorganisme pengurai polutan lingkungan. Pada kajian ini, basidiomisetes diisolasi dari sampel-sampel tubuh buah dan kayu lapuk yang diambil dari tujuh provinsi di Indonesia. Tiga ratus tujuh puluh isolat basidiomisetes telah diseleksi aktivitasnya sebagai pendegradasi dioksin. Metode dye-decolorization digunakan pada seleksi ini. Hasil seleksi menunjukkan bahwa enam puluh isolat basidiomisetes memiliki aktivitas sebagai pendegradasi dioksin, tiga isolat di antaranya menunjukkan aktivitas tertinggi.Kata kunci: Ligninolisis, basidiomisetes, biodegradasi, dioksin, jamur
