Pendahuluan: Produksi amilase telah diteliti menggunakan bakteri yang diisolasi dari tanah Api Kayangan Bojonegoro Jawa Timur. Tujuan: Penelitian ini bertujuan mengisolasi dan identifikasi bakteri dan menggetahui efek kondisi kultur pada aktivitas amilase. Metode: Bakteri dikulturkan pada media yang mengandung pati terlarut sebagai sumber karbon tunggal. Penambahan kalsium (15 mM) atau ekstrak yeast (0,5%) dan pepton (2%) ke media pati terlarut dan mineral akan mengurangi waktu fase lag dan memperpanjang pertumbuhan dan produksi amilase. Pemberian glukosa pada kultur mengurangi produksi amilase, sehingga menunjukkan bahwa efek glukosa berpengaruh pada organisme ini. Hasil: pH media awal dan suhu optimum pada produksi amilase oleh organisme masing-masing 7,0 dan 50°C. Suhu dan pH optimal untuk aktivitas masing-masing 50°C dan 6,0. Larutan enzim dipertahankan aktivitasnya 100% saat diinkubasi pada suhu 90°C selama satu jam dan 40% pada suhu 60°C selama 24 jam. Kesimpulan: Pemberian glukosa pada kultur akan menurunkan produksi amilase.

Background: A simple bio-assay for determination of streptomycin hyphenated with planar chromatography techniques was developed. Objective: This study aims to validate the method for identification and determination of streptomycin in injection preparations with TLC-bioautography. Methods: Thin Layer Chromatography (TLC) was performed on the silica Gel GF-254 using KH2PO4 solution as mobile solvent. The visualization was performed by spraying 2% resorcinol. Direct bi autography was developed using Escherichia coli ATCC 25922 as a bacterial test, grown on the nutrient agar medium at 37oC for 24 hours. The method was validated corresponding to linearity, limit of detection (LOD), intra day precision, and accuracy parameters. The accuracy was measured using streptomycin injection as a sample. Results: The Results showed that the KH2PO4 solution at 7.5% concentration was found to be the optimized solvent with Rf value of 0.5. The linear equation was y = 10.176x + 4.046 at 150 - 350 µg/mL concentration range with the linearity coefficient, Limit of Detection, accuracy, and variation coefficient were 0.9907; 40 ppm; 96.37 + 2.22% (with an RSD value of 2.31%); and 1.63 respectively. Conclusion: The prospective TLC-bioautographic method was applied for the identification and determination of streptomycin in a preparation using a single eluent KH2PO4. The eluent system optimization remains necessary for the identification and determination of the mixture of streptomycin with other antibiotics, such as aminoglycoside groups.

Introduction: Staphylococcus aureus and Pseudomonas aeruginosa are the most dangerous and important species among their genus. These bacteria are often resistant to many classes of antimicrobial agents; which make difficulties in selecting appropriate drug to treat infections. Multidrug-resistance occurs readily in hospitals for which antimicrobials agents were used widely. Objective: The aims of this study was to determine minimum inhibitory concentration (MIC) and minimum bacterial concentration (MBC) of levofloxacin against 22 multidrug resistant- clinical (MDR) strains of Staphylococcus aureus and Pseudomonas aeruginosa isolated from patients pus and urine in hospital. Methods: Determination of the MIC was performed by macro-dilution broth assay as recommended by Clinical and Laboratory Standards Institute (CLSI), while the MBC was determined one-step further after the MIC determination. Results: It was found that MIC of the levofloxacin were (0.3 ± 0.0) - >0.5 µg/mL and (0.2 ± 0.1) - (1.0 ±0.0)µg/mL against S. aureus from pus and urine, respectively. In addition, higher MICs were yielded against P. aeruginosa, (1.0 ± 0.0) - >8.0 µg/mL and (0.7 ± 0.3) - (3.0 ± 1.2) µg/mL for pus and urine isolates respectively. Similar to MICs, the MBCs against P. aeruginosa were higher than S. aureus, (0.6 ± 0.0) - > 4.0 µg/mL and (0.3 ± 0.0) - >8.0 µg/mL isolated from pus and urine respectively, (2.0 ± 0.6) - > 8.0 µg/mL and (3.0 ± 1.2) - >7.0 µg/mL against P. aeruginosa from pus and urine respectively. Conclusion: The levofloxacin was still susceptible as bacteriostatic against isolates from both body fluids, but not bactericidal towards all isolates.
