Abstract

Cephalosporins are the most widely used class of β-lactam antibiotic in the world and clinically active against gram positive and gram negative bacteria. Cephalosporin C (CPC) is naturally produced by fungus Cephalosporiun acremonium. CPC has moderate antibacterial activity with minimum inhibitory concentration values of 25-100 µg/mL and 12-25 µg/mL for gram-positive and for gram-negative bacteria, respectively. CPC can be converted into 7-aminocephalosporonic acid (7-ACA) as intermediate compound for cephalosporin derivatives by two-steps or one-step enzymatic method. Two-step enzymatic method uses D-amino acid oxidase (DAAO) to produce glutaryl-7-amino cephalosporanic acid (GL 7-ACA) for the first step and GL-7-ACA acylase to produce 7-ACA for the second step. One-step enzymatic method uses CPC acylase to convert CPC into 7-ACA directly. Some microorganisms produce CPC acylase, such as Pseudomonas sp., Bacillus megaterium, Aeromonas sp., dan Arthrobacler. A natural CPC acylase has low activity and genetic engineering was used to increase its activity.Keywords: Cephalosporin, cephalosporin acylase, 7-ACA, genetic engineering, mutation ABSTRAKSefalosporin merupakan antibiotik golongan β-laktam yang paling banyak digunakan di dunia dan secara klinis aktif terhadap bakteri gram positif dan gram negatif.

Abstract

Plasmids are extra chromosomal molecules of DNA that replicate autonomously and found in prokaryote and eukaryote cells. There are a number of methods that are used to isolate plasmids, such as alkaline lysis, boiling lysis, using cesium chloride, and chromatography. Amongst the disadvantages in plasmid isolation methods are lengthy time especially when handling a large number of samples, high cost, and low purity. Alkaline lysis is the most popular for plasmid isolation because of its simplicity, relatively low cost, and reproducibility. This method can be accomplished in 50 minutes to one hour. In this research, the alkaline lysis method was developed to obtain suitable plasmid for applications in a molecular biology laboratory. The aim of this research was to reduce contaminants and improve yield of plasmid. The result of isolation of pICZA plasmid in Escherichia coli gave the concentration of 3.3 to 3.8 µg/µL with the purity of 1.99.Keywords: Plasmid isolation, pICZ A, Escherichia coli, rapid, alkaline lysis  ABSTRAKPlasmid merupakan molekul DNA ekstrakromosomal yang bereplikasi secara mandiri dan ditemukan dalam sel prokariot dan eukariot.

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.

Abstract

Lovastatin is a drug belonging to statins group that is used to decrease the cholesterol levels in blood. The action mechanism of lovastatin is inhibition of the activity of HMG-CoA reductase enzyme, hence reducing cholesterol production in the liver. Some filamentous fungi produce lovastatin, and Aspergillus terreus is known as the highest lovastatin-producing filamentous fungi, therefore it is generally used for production of lovastatin. Commercial production of lovastatin is based on submerged fermentation. But nowadays solid-state fermentation is becoming an alternative for production of lovastatin. Lovastatin is mainly used for antihypercholeterolemia. Other potential uses of lovastatin include therapy of Alzheimer’s disease, cancer, osteoporosis, Parkinson’s disease, multiple sclerosis, and rheumatoid arthritis.Keywords: Statin, lovastatin, Aspergillus terreus, fermentation, antihypercholeterolemia ABSTRAK Lovastatin merupakan obat golongan statin yang digunakan untuk menurunkan kadar kolesterol dalam darah.

Abstract

Availability of drugs in Indonesia is still limited by the high prices of drugs due to on the imported raw materials that reaches 95%. Developing antibiotic raw materials can be achieved by increasing of penicillin G production, which is the raw material for the formation of semisynthetic penicillin derivatives through the production of 6-aminopenisillanic acid (6-APA). One of the important enzyme in the penicillin G biosynthesis is Isopenisilin N Synthase (IPNS) that encodes by pcbC gene on Penicillium chrysogenum. This study aimed to obtain a recombinant of pcbC gene fragments that is inserted into pPICZA plasmid. Amplification of pcbC gene used pcbC-F and pcbC-R primers. The pcbC gene fragment was inserted into pPICZA vector and then transformed into TOP 10 F’. The results showed that the recombinant of the pcbC gene fragment from P. chrysogenum has been obtained. Analysis of DNA sequences using the BLAST program showed that the pcbC gene fragment has high homology (99%) with the  pcbC gene from P. chrysogenum Wisconsin 54-1255 and P. chrysogenum AS-P-78 which encodes IPNS   Keywords: pcbC Gene, Penicillium chrysogenum, cloning, penicillin G

Abstract

Aspergillus terreus is a Saprophyte fungus that produces several secondary metabolites as lovastatin (anti-cholesterol drug) and itaconic acid (a polymer material). Lovastatin is one of the statin class of drugs that have efficacy as antihypercholesterolemic. Plasmid transformation is the introduction and incorporation of exogenous plasmid into cells orprotoplast. In this study, pTRLI plasmid (pTRI inserts containing lovE gene as a regulator gene in the biosynthesis of lovastatin) will be transformed by electroporation transformation. The purpose of this research is transformation of pTRLI plasmid into protoplasts of Aspergillus terreus by electroporation and obtain stable transformants. The research was initiated by isolation of pTRLI plasmid. Then pTRLI plasmid was determined purity and concentration by nanodrop. Furthermore, Protoplasts of Aspergillus terreus were isolated enzymatically by adding an enzyme which can degrade the cell wall of Aspergillus terreus which contains chitin and cellulose. PTRLI plasmid were transformed into protoplasts of Aspergillus terreus by electroporation. These transformants were grown in Czapek-Dox medium containing pyrithiamine agar and the number of transformants mg-1 of pTRLI plasmid was calculated. Transformants were selected to grow in Czapek-Dox medium containing piritiamin 1 mg l-1. The number of transformants produced 187 transformants mg-1 of PTRLI plasmid. Transformants are stable up to five generations by growing the transformants in Czapek-Dox medium agar containing piritiamin 1 mg l-1. The success of the transformation indicated by ptrA gene in transformants that can be amplified by PCR. The size of fragment DNA is 801 bp.
