Abstract

Purification of Cephalosporin-C Acylase and Its Optimization of Ion-Exchange ChromatographyABSTRACTCephalosporin-C acylase (CCA) has an important role in the one-step conversion of cephalosporin-C into 7-ACA. Purification process aims to increase specific activity of CCA enzyme. Purification began with cell lysis, ammonium sulphate precipitation, dialysis, ion exchange chromatography (IEC) and size exclusion chromatography. IEC optimization of elution step was also done to compare gradient and isocratic elusion. Purification was capable to increase the enzyme purity upto 33.66 fold, with specific activity of 3.00 U/mg and the yield reached 41.41%. Optimization of elusion during IEC showed that isocratic protein elusion was more efficient (taking shorter time, 3 column volume (CV) only) than that of gradient batch (up to 9 CV). SDS-PAGE analysis demonstrated that the recombinant CCA enzyme existed in two types, active enzyme containing α-subunit (25 kDa) and β-subunit (58 kDa), and inactive enzyme (83 kDa) as precursor. Furthermore, 30% ammonium sulphate saturated precipitation was able to precipitate this inactive CCA.Keywords: 7-ACA,CCA, cephalosporin C, protein purification, specific activity ABSTRAKSefalosporin-C asilase (CCA) merupakan enzim yang berperan penting dalam konversi satu tahap sefalosporin-C menjadi 7-ACA. Proses purifikasi merupakan salah satu cara untuk meningkatkan aktivitas spesifik enzim CCA. Proses purifikasi dimulai dari memecah sel, diikuti dengan tahap presipitasi menggunakan amonium sulfat, dialisis, kromatografi penukar ion (IEC) dan kromatografi eksklusi. Optimasi proses IEC pada tahap elusi juga dilakukan untuk membandingkan elusi enzim CCA secara gradien dan isokratik. Proses purifikasi pada penelitian ini mampu meningkatkan kemurnian enzim hingga 33,66 kali, dengan aktivitas spesifik sebesar 3,00 U/mg dan perolehan enzim sebesar 41,41%. Hasil optimasi IEC pada proses elusi secara isokratik lebih efisien dari segi waktu (hanya membutuhkan 3 kolom volume (CV) dibandingkan dengan secara gradien (sampai 9 CV). Hasil SDS-PAGE menunjukkan bahwa CCA rekombinan merupakan enzim dengan 2 macam bentuk yaitu enzim aktif, yang terdiri dari subunit α (25 kDa) dan β (58 kDa), dan enzim tidak aktif berupa prekursor (83 kDa). Proses presipitasi menggunakan amonium sulfat 30% tersaturasi dapat mengendapkan prekursor CCA.Kata Kunci: 7-ACA, aktivitas spesifik, CCA, purifikasi protein, sefalosporin C

Abstract

In Vitro Multiplication of  Black Orchid (Coelogyne pandurata Lindl.) Using the Combination of NAA and BAPABSTRACTBlack orchid is an indigenous plant from Kalimantan, Indonesia. It becomes endangered because of forest over-exploitation and its low natural reproduction rate. Tissue culture is considered to offer a solution to conserve and propagate this species. The aim of this research was to evaluate the effect of Naphtalene Acetic Acid (NAA) and 6-Benzile Amino Purine (BAP) on shoots multiplication of black orchid. The basic medium used was a half of Murashige & Skoog (MS) composition supplemented with 150 mLL-1 coconut water. Initial explants used were 6-month-old shoots of germinating seeds. The shoot cultures were incubated for 23 weeks. Results showed that the best combination for shoot multiplication was NAA 0.0 mgL-1 with BAP 0.2 mgL-1. Shoot grew better on medium with BAP and without NAA while roots growth was better on medium without the two plant growth regulators. The addition of BAP up to 0.3 mgL-1 increased the leaf number, which however decreased at higher BAP concentration.Keywords: BAP, black orchid, Coelogyne pandurata, multiplication, NAA ABSTRAKAnggrek hitam merupakan flora langka asli Kalimantan, Indonesia. Keberadaa anggrek ini di alam semakin langka akibat eksploitasi berlebihan dan sulitnya perbanyakan secara alami. Kultur jaringan merupakan metode untuk mengatasi kelangkaan anggrek ini. Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi NAA dan BAP terhadap multiplikasi anggrek hitam. Media dasar yang digunakan adalah ½ MS dengan penambahan air kelapa 150 mLL-1. Eksplan yang digunakan adalah tunas hasil semai biji umur 6 bulan. Kultur tunas diinkubasi selama 23 minggu. Hasil penelitian menunjukkan bahwa kombinasi terbaik untuk multiplikasi tunas adalah NAA 0 mgL-1 dengan BAP 0,2 mgL-1. Tunas tumbuh lebih baik dalam media dengan penambahan BAP tanpa NAA, sedangkan akar pada media tanpa NAA dan BAP. Penambahan BAP sampai 0.3 mgL-1 mampu meningkatkan jumlah daun, namun menurun dengan penambahan di atas konsentrasi tersebut.Kata Kunci: anggrek hitam, BAP, Coelogyne pandurata, multiplikasi, NAA

Abstract

Review on Rapid Diagnosis Method and Treatment of Salmonella typhi Infection ABSTRACTSalmonella is a genus of gram-negative bacilli which are pathogenic for human. Recently over 2,500 serotypes of Salmonella have been reported. Of these, the most common serotype causing typhoid fever which is acute infectious disease in small intestine due to S. typhi entering the body through contaminated food or drink. S. typhi infection remains a major public health concern worldwide because of the subsequent economic burden for the cost of surveillance, prevention, and treatment. In Indonesia, typhoid fever is an endemic disease that threatens public health and becomes a complex problem because it increases career cases and drug resistance, so its diagnosis is needed. Although there is already a diagnosis method of typhoid fever conventionally, a fast, easy and reliable diagnosis method is needed to diagnose typhoid fever by medical personnel in endemic countries. Typhoid fever is treated by antibiotics and prevention efforts are carried out through vaccination.Keywords: antibiotics, pathogen, rapid detection, Salmonella typhi, typhoid fever ABSTRAKSalmonella adalah bakteri basil gram negatif yang bersifat patogen terhadap manusia dan saat ini telah dilaporkan lebih dari 2.500 serotipe.

Abstract

Identification of Actinomycetes in Freshwater Sediments from Mamasa, West Sulawesi and Their Antibacterial and Phosphate Solubilizing ActivitiesABSTRACTA large number of actinomycetes that have been isolated and screened were obtained from soil and marine samples. Consequently, the possibility of isolating novel Actinomycetes and secondary metabolites compounds strains from soil and marine samples have limited. Exploration of actinomycetes from freshwater sediment is rare. In this study, 30 isolates of Actinomycetes from freshwater sediments in Mamasa District, West Sulawesi were isolated, identified, and screened for their antibacterial and phosphate solubilizing activity. Actinomycetes were isolated by serial dilution method and were identified based on morphological and 16S rRNA gene sequence. Antibiotic activity was screened using the agar plug diffusion method, while soluble phosphate ability was observed by clear zone ratio in PKA medium. Most of the isolates belong to the genus Streptomyces (80%). Out of 30 isolates, 56.6% showed antibacterial activity and 36.6% had potential as solubilizing phosphate which belong to genus Streptomyces, Actinomadura, and Kitasatospora.Keywords: 16S rRNA, Actinomycetes, antibacterial, freshwater sediment, phosphate solubilizing ABSTRAKSebagian besar aktinomisetes yang telah diisolasi dan dilakukan penapisan metabolit sekundernya berasal dari sampel tanah dan laut. Konsekuensinya, kesempatan untuk menemukan aktinomisetes jenis baru maupun yang menghasilkan metabolit sekunder baru dari tanah dan laut semakin berkurang. Eksplorasi aktinomisetes dari lingkungan lain seperti sedimen air tawar jarang dilakukan. Pada penelitian ini, 30 isolat aktinomisetes yang diisolasi dari sedimen air tawar di Kabupaten Mamasa, Sulawesi Barat, telah diidentifikasi dan dilakukan penapisan antibakteri dan kemampuan isolat dalam melarutkan fosfat. Aktinomisetes diisolasi dengan metode pengenceran secara langsung dan selanjutnya diidentifikasi secara morfologi dan molekular berdasarkan gen 16S rRNA. Metode yang digunakan dalam penapisan aktivitas antibakteri adalah agar plug diffusion method, sedangkan kemampuan aktinomisetes dalam melarutkan fosfat diuji dengan cara menumbuhkan isolat pada media PKA. Isolat yang paling banyak diisolasi termasuk ke dalam marga Streptomyces (80%). Dari 30 isolat, 56,6% isolat menunjukkan adanya aktivitas antibakteri dan 36,6% dari isolat berpotensi sebagai pelarut fosfat, yang termasuk ke dalam marga Streptomyces, Actinomadura, dan Kitasatospora.Kata Kunci: 16S rRNA, Aktinomisetes, sedimen air tawar, antibakteri, pelarut fosfat
