Abstract

Utilization of agroindustrial byproduct as cheap raw materials for aquafeed was hampered by its poor nutritional value as well as high antinutrition content which could be overcome through fermentation. Coconut testa (CT) and cassava bagasse (CB) were mixed, and fermented using Rhizopus oryzae for preparing aquafeed. Subsequent feeding test was carried out on tilapias (Oreochormis niloticus L.) using 5 feeding treatments: one unfermented feed (commercial feed 100%), and the other four feeds produced by fermentation using substrate mixture of CT and CB in 4 different ratios, namely 100%:0%, 75%:25%, 50%:50%, and 25%:75%. Feeding 100% commercial feed (true protein 22.64% and crude fibre 14.67%) showed the best results on the fish growth with body weight gain of 3.96 g and feed conversion ratio of 8.63. Meanwhile, feeding fermented feeds (true protein 7.96-20.27% and crude fiber 14.14-18.47%) resulted in body weight gain in the range of 2.22 to 2.75 g with feed conversion ratio of 10.89 to 13.62. Thus, the fermented feeds promoted growth in tested tilapias albeit less optimally than commercial feed did.Keywords: Rhizopus oryzae, Oreochromis niloticus, coconut testa, cassava bagasse, fermentation ABSTRAKPenggunaan hasil samping agroindustri sebagai bahan pakan murah ikan terkendala rendahnya nutrisi dan tingginya antinutrisi yang dapat diatasi melalui fermentasi. Dalam penelitian ini, kulit daging buah kelapa (KK) dan onggok singkong (OS) dicampur dengan perbandingan tertentu, lalu difermentasi menggunakan Rhizopus oryzae untuk pakan ikan. Uji pemberian pakan dilakukan terhadap ikan nila (Oreochormis niloticus L.) dengan 5 perlakuan: satu perlakuan pakan tanpa fermentasi (pakan komersial 100%), dan empat perlakuan pakan fermentasi substrat campuran KK dan OS dengan 4 perbandingan yang berbeda, yakni 100%:0%, 75%:25%, 50%:50%, dan 25%:75%. Pemberian pakan komersial 100% (protein sejati 22,64% dan serat kasar 14,67%) memperlihatkan hasil terbaik pada pertumbuhan ikan nila dengan pertambahan bobot badan 3,96 g dan rasio konversi pakan 8,63. Sebaliknya, pemberian pakan fermentasi (protein sejati berkisar 7,96-20,27% dan serat kasar 14,14-18,47%) menghasilkan pertambahan bobot badan ikan pada kisaran 2,22-2,75 g dengan rasio konversi pakan 10,89-13,62. Dengan demikian pakan fermentasi tersebut mendorong pertumbuhan ikan nila namun kurang optimal dibandingkan pakan komersial.Kata Kunci: Rhizopus oryzae, Oreochromis niloticus, kulit daging buah kelapa, onggok, fermentasi

Abstract

Cephalosporin is a β-lactam antibiotic produced by Acremonium chrysogenum using submerged fermentation. Carbon and nitrogen are the most influential medium ingredients for cephalosporin formation. The purpose of this study was to obtain the best composition of media for cephalosporin C production. Response surface methodology was used for production optimization. The results showed that molasses of 70 g/Lwas the best carbon source, while the best nitrogen source was the combination of corn steep liquor, urea and ammonium sulphate. DL-methionine, carbon, and nitrogen source significantly affected  the production of cephalosporin C. The mathematically modelled optimization showed that the highest production of cephalosporin C (3876 mg/L) was obtained using medium composition of 68.28 g/L molasses, 71.61 g/L nitrogen, and 0.4 g/L DL-methionine. Laboratory verification using the same medium composition produced 3696 mg/L of cephalosporin C, being 4.65% different from the mathematically optimized results. Medium optimization increased the cephalosprin C production which was 1.48 times higher than that using the previous medium, where the maximum production was only 2487 mg / L.Keywords: Carbon,  cephalosporin C, cultivation medium, nitrogen, A. chrysogenum ABSTRAKSefalosporin C adalah golongan antibiotik β-lactam yang dihasilkan Acremonium chrysogenum melalui fermentasi cair.

Abstract

Meningkatkan Fungsi CRISPR-Cas9 untuk Terapi Pengeditan GenPengeditan gen menjadi mudah dilakukan sejak ditemukannya clustered regularly interspaced short palindromic repeat (CRISPR) dan CRISPR-associated protein 9 (Cas9) sebagai alat untuk menyunting gen suatu organisme. Sebagian besar penyakit genetik tidak dapat disembuhkan secara kausal dengan terapi yang ada, maka pengeditan gen merupakan suatu cara yang prospektif dalam terapi medis di masa depan. Sayangnya, pengeditan gen dengan Cas9 yang ada saat ini masih memiliki banyak kelemahan, yaitu: 1) kurang spesifik, di mana RNA pemandu dapat berikatan dengan beberapa segmen pada genom manusia, sehingga memungkinkan terjadinya salah target; 2) kurang efisien, karena sekalipun telah berhasil memotong utas ganda DNA, kebanyakan penyambungan kembali akan dilakukan secara non-homology end joining (NHEJ), yang justru meningkatkan peluang terjadinya mutasi; 3) sulit disalurkan ke dalam inti sel karena berbagai sawar fisiologis maupun biokimiawi. Tulisan ini akan membahas perkembangan terkini dalam mengatasi ketiga masalah di atas. Untuk meningkatkan spesifisitas, dapat dilakukan modifikasi RNA pemandu dan struktur Cas9. Efisiensi dapat ditingkatkan dengan meningkatkan peluang terjadinya homology-directed repair dibandingkan NHEJ, sedangkan untuk meningkatkan distribusi ke dalam sel, dapat digunakan berbagai macam vektor, seperti virus dan nanopartikel. CRISPR-Cas9 merupakan area yang aktif diteliti dalam bidang biosains, dan dalam waktu dekat, diharapkan dapat dimanfaatkan dalam bidang klinik.Kata kunci: CRISPR, Cas9, efektivitas, spesifisitas, terapi genABSTRACTGene editing has become reasonably easy since the discovery of clustered regularly interspaced short palindromic repeat (CRISPR) and CRISPR-associated protein 9 (Cas9). Most genetic diseases cannot be treated causally, and currently available therapies are mainly symptom-based. To treat the etiology of genetic diseases, a firm gene editing therapy is necessary to be established. This posits Cas9-facilitated gene editing as a prospective modality to become a clinically approved therapy in the future to treat genetic disorders. However, until recently, Cas9-based genome editing is still facing several hurdles, including low specificity, low effectiveness, and difficult delivery. Currently available Cas9 nucleases are able to bind to non-specific DNA sequence and produce non-specific cleavage. The efficiency has been relatively low due to the preference of non-homologous end-joining (NHEJ) over homology-directed repair (HDR) by the host cell. Furthermore, in order to deliver Cas9 into the nucleus, multiple physiological barriers have to be overcome. This review discussed recent developments in tackling these three hurdles, ranging from designing the guide RNA using multiple bioinformatics tools, modifying Cas9 structure, as well as packaging the nuclease-guide RNA complex into viral vectors and nanoparticles. Considering the active research on this area, it is expected that CRISPR/Cas9 can be utilized as a clinical therapy in the near future.Received: 02 June 2017        Accepted: 07 July 2017        Published: 19 July 2017

Abstract

Effects of Lactic Acid Bacteria Combination on Characteristic Change of Buffalo Milk Nutrition Determination of physical and chemical characteristics on fermented milk using a mixture of Lactobacillus bulgaricus, Streptococcus thermophilus, and Bifidobacterium sp. has been conducted. Fermentation was carried out for 20 hours at 37ºC in a facultative aerobic condition. Physical characteristics were performed by comparing the physical properties before and after fermentation such as viscosity and texture, including chemical properties such as pH, acidity, protein, fat, and sugar contents. Inoculants of lactic acid bacteria were varied using a combination of lactic acid bacteria mixture. Results showed that the combination of bacteria inoculants used has no significant effect on changes in protein, fat, ash, and water contents. However, the effects on total acid, pH, sugar content, and physical appearance such as viscosity and texture were significant. The combination of L. bulgaricus, S. thermophilus and Bifidobacterium sp. (A6) produced a soft texture appearance and high viscosity. The combination of inoculant bacteria L. bulgaricus with S. thermophilus (A5) produced a texture similar to A6 but with a lower viscosity than A6.Keywords: Lactobacillus bulgaricus, Streptococcus thermophilus, Bifidobacterium sp, buffalo milk, fermentation. ABSTRAKPenelitian untuk mengetahui karakteristik fisik dan kimia hasil fermentasi susu kerbau menggunakan campuran Lactobacillus bulgaricus, Streptococcus thermophilus, dan Bifidobacterium sp telah dilakukan. Fermentasi dilakukan selama 20 jam pada suhu 37ºC secara aerobe fakultatif. Karakteristik fisika dilakukan dengan membandingkan sifat fisik seperti kekentalan dan tekstur, serta sifat kimia yang meliputi kandungan protein, lemak, gula, pH, keasaman sebelum dan sesudah fermentasi. Inokulan bakteri asam laktat divariasikan menggunakan kombinasi campuran bakteri asam laktat. Hasil penelitian menunjukkan bahwa kombinasi inokulan yang digunakan dalam proses fermentasi susu kerbau tidak berpengaruh nyata terhadap perubahan kadar protein, lemak, abu, dan air. Namun demikian berpengaruh nyata terhadap total asam, pH, kadar gula, dan penampakan fisik seperti kekentalan dan tekstur. Kombinasi inokulan L. bulgaricus, S. thermophilus dan Bifidobacterium sp. (A6) menghasilkan susu fermentasi dengan penampakan tekstur halus dan kekentalan yang lebih padat. Kombinasi bakteri L. bulgaricus dengan  S. thermophilus (A5) menghasilkan tekstur yang mirip dengan A6, namun demikian menghasilkan kekentalan yang lebih rendah dibandingkan A6.Kata kunci: Lactobacillus bulgaricus, Streptococcus thermophilus, Bifidobacterium sp, susu  kerbau, fermentasi

Abstract

Production of Cephalosporin Acylase Recombinant as Biocatalyst for 7-Aminocephalosporanic Acid Production7-aminocephalosporanic acid (7-ACA) is a precursor for the production of semisynthetic cephalosporin derivatives. The enzymatic 7-ACA production can use two-stage and one-step enzymatic methods. Two-stage enzymatic method uses D-amino acid oxidase (DAAO) enzyme to produce glutaryl-7-aminocephalosporanic acid (GL-7-ACA) in the first stage and glutaryl-7-aminocephalosporanic acid acylase to produce 7-ACA in the second stage. The one-stage enzymatic method using cephalosporin acylase (CPC acylase) converts the CPC to 7-ACA directly. The aim of this research was to produce recombinant CPC acylase in Escherichia coli BL21(DE3). Transformantion culture E. coli BL21(DE3) was induced with concentrations of IPTG 0; 0.25; 0.5; 0.75; 1; 2 mM for 5 hours. The induction time of IPTG was determined at 0, 1, 2, 3, 4, and 5 hours. The results showed that CPC acylase produced by E. coli BL21(DE3) with optimum condition of CPC acylase production was 0.5 mM IPTG and optimal induction time of IPTG was 5 hours.Keywords: Cephalosporin, cephalosporin acylase, 7-ACA, protein expression, Escherichia coli BL21(DE3) ABSTRAKAsam 7-aminosefalosporanat (7-ACA) merupakan prekursor untuk produksi turunan sefalosporin semisintetik. Produksi 7-ACA secara enzimatik dapat menggunakan metode dua tahap dan satu tahap enzimatik. Metode enzimatik secara dua tahap menggunakan enzim asam D-amino oksidase (DAAO) untuk menghasilkan asam glutaril-7-aminosefalosporinat (GL-7-ACA) pada tahap pertama dan menggunakan asam glutaril-7-aminosefalosporinat asilase untuk menghasilkan 7-ACA pada tahap kedua. Metode enzimatik satu tahap dengan sefalosporin asilase (CPC asilase) mengubah CPC menjadi 7-ACA secara langsung. Tujuan penelitian adalah memproduksi rekombinan CPC asilase di dalam sel Escherichia coli BL21(DE3). Kultur Transforman E. coli BL21(DE3) diinduksi dengan konsentrasi IPTG 0; 0,25; 0,5; 0,75; 1; 2 mM selama 5 jam. Waktu induksi IPTG ditentukan pada 0, 1, 2, 3, 4 dan 5 jam. Hasil penelitian menunjukan bahwa CPC asilase diproduksi oleh E. coli BL21(DE3) dengan kondisi optimal produksi CPC asilase adalah konsentrasi IPTG 0,5 mM dan waktu induksi IPTG optimal adalah 5 jam.
