Abstract

Existence of heavy metals in industrial waste is gaining global attention since their negative impact to environment. One of the efforts to solve the problem was to use plant to absorb metal in liquid medium, known as rhizofiltration. This research was aimed to select aquatic plants which showed relative resistantce and susceptibility to chromium. Four species of aquatic plants (Pistia stratiotes, Eichhornia crassipes, Lemna minor and Salvinia sp.) were grown in artificial medium (Hoagland) supplemented with 0, 1, 2, 4 and 8 ppm chromium. The plants resistance and absorption toward chromium was observed based on the morphology and chromium content in their biomass. Based on their resistance to and absorption of chromium, the selected plants were tested further in liquid waste of tanning industry. In Hoagland medium, Salvinia sp. demonstrated 67.2% higher resistance and absorption toward chromium while that of P. stratiotes 20.3% lower compared to other plants which were tested. This result could be applicable in reducing such environmental pollutant as the heavy metal chromium from industrial waste.

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.

Abstract

Screening and Identification of Ligninolytic Microbes in the Natural Decomposition of Oil Palm Empty Fruit Bunch  ABSTRACTOPEFB (oil palm empty fruit bunch)could potentially be utilized as organic fertilizer or animal feed through composting. Information on microorganisms that play important roles in the natural decomposition of OPEFB is to date not much known yet. This research was aimed to obtain and, subsequently, to molecularly identify lignin-degrading microbial isolates responsible for naturally decomposing OPEFB in the Oil Plant Plantation and Palm Oil Refinery Plant, PTPN VIII Cikasungka, Bogor. Screening for active lignin-degrading isolates was carried out on 17 naturally decomposing OPEFB samples. A total of 19 isolates of fungi and 80 isolates of bacteria were obtained. Ligninolytic activity was measured by Sundman and Nase testing methods. Ligninolytic activity was found on 13 fungal isolates and 15 bacterial isolates. The active isolates were subsequently identified molecularly based on ITS sequence in the ribosome DNA area for fungi and in 16S rRNA genes for bacteria. The results showed that the lignin-degrading microorganisms obtained consisted of 5 bacterial isolates from the genus Bacillus and 3 fungal isolates from the genus Rhizopus and Aspergillus. Keywords: composting, lignin, microbes, OPEFB, 16S rRNA ABSTRAKTKKS (tandan kosong kelapa sawit) berpotensi dimanfaatkan sebagai pupuk organik atau pakan ternak dengan cara pengomposan.

Penelitian ini bertujuan mendapatkan isolat mikroba pendegradasi lignin dalam pengomposan alami TKKS asal Perkebunan dan Pabrik Pemerasan Kelapa Sawit, PTPN VIII Cikasungka, Bogor, serta mengidentifikasi mikroba tersebut secara molekuler. Skrining mikroba aktif pendegradasi lignin dilakukan terhadap 17 sampel TKKS yang sudah lapuk secara alami. Sebanyak 19 isolat jamur dan 80 isolat bakteri telah dihasilkan. Aktivitas ligninolitik diukur dengan metode pengujian Sundman dan Nase. Isolat jamur yang memiliki aktivitas ligninolitik sebanyak 13 isolat, sedangkan bakteri sebanyak 15 isolat. Isolat-isolat aktif tersebut selanjutnya diidentifikasi secara molekuler berdasarkan pada sekuen ITS di daerah DNA ribosom untuk jamur dan menggunakan gen 16S rRNA untuk bakteri. Hasil menunjukkan bahwa 5 isolat bakteri yang memiliki kemampuan mendegradasi lignin berasal dari genus Bacillus, sedangkan 3 isolat jamur pendegradasi lignin berasal dari genus Rhizopus dan Aspergillus Kata Kunci: lignin, mikroba, pengomposan, TKKS, 16S rRNA

Abstract

Curcuma longa is a medicinal plant renowned for its therapeutic properties and potential treatment of cancer. This study focused on the biosynthesis of diterpenoids in the rhizome and leaves of C. longa. The genes responsible for producing these medicinal compounds were analyzed using BLASTx, Gene Ontology (GO) annotation, differential expression, and homology. The substantial dataset was obtained from the National Center for Biotechnology Information (NCBI), comprising 151,730,334 clean reads and 167,264 transcripts for the analysis. The results of the BLASTx analysis were as follows: NR yielded 65.93%, Swiss-Prot yielded 44.52%, and COG yielded 17.35%. Subsequently, GO annotation was performed using Blast2GO, resulting in an annotation rate of 56.79%. Differential expression analysis revealed a total of 636 genes that were significantly differentiated between the rhizome and leaves. The homology analysis resulted in 11 proteins associated with diterpenoid biosynthesis and nine proteins related to CYP450. Approximately three class I proteins were highly expressed in the rhizome. Additionally, seven CYP450 enzymes from the CYP71D and CYP726 subfamilies were identified; three were highly expressed in the rhizome. The expression patterns of these enzymes were similar to the aforementioned three class I diTPSs, indicating their potential involvement in macroditerpenoid biosynthesis in C. longa. These findings provide valuable genomic resources for future functional genomics research on C. longa, facilitating targeted efforts to enhance the production of bioactive compounds.

Abstract

Patients with diabetes mellitus increase significantly every year. The increasing number of people with diabetes mellitus results in increased insulin requirements. There are two types of insulin used for diabetes mellitus treatment: human insulin and insulin analogues. Escherichia coli, Pichia pastoris, Saccharomyces cerevisiae, or Hansenula polymorpaha has been used to produce human insulin and insulin analogues. Pichia pastoris can produce glargine in large quantities, and the insulin protein produced will be secreted outside the cell to facilitate the purification process. The advantage of glargine has a long working time of up to 24 hours. Hence, glargine is more effective because patients with diabetes receive glargine injections only once daily. The research started with cloning the glargine gene, transforming pPICZαA-G plasmid into Pichia pastoris, and testing glargine production. 20 recombinant Pichia pastoris colonies were selected and regenerated. Eight recombinant Pichia pastoris colonies were tested for glargine production, and six colonies were detected producing glargine by electrophoresis SDS-PAGE gel stained with Coomassie blue. This study aims to produce glargine using Pichia pastoris as an expression system capable of producing glargine extracellularly, thus simplifying the purification process.

Abstract

Maman plant (Cleome gynandra L.) is an underutilised leafy vegetable that has a high nutritive value and contains phenolic compounds that are essential in reducing or preventing the occurrence of chronic and infectious diseases. In this study, we investigate the effect of drying methods on the total phenolic content of maman plant from Riau. The drying treatment process for maman leafs was tried using three methods: room air-dried without sunlight exposure at 21-24oC for seven days, freeze-dried at -40oC for four days, and oven-drying at 40oC for three days. Freeze-dried maman leafs exhibited significantly (p < 0.05) higher total phenolics (5,90 mgGAE/g) than those dried using other methods, followed by oven-dried (5,14 mgGAE/g) and room-air dried (4,50 mgGAE/g). Drying maman leaves for further research is recommended using the freeze-dried method to obtain optimal phytochemical content.
