Abstract

This research aimed to determine the potential of endophytic Trichoderma sp originated from oil palm plant tissue as a biological control agent and its molecular identification. The potency assay was carried out using a completely randomized design consisting of three isolates of Trichoderma sp. from different plant tissues (TR01 from root tissue, TS01 from stem tissue, and TM01 from midrib tissue) with inhibitory ability parameters. The inhibition of the growth of G. boninense was performed at the concentration of 15% and 20%, and the molecular identification of Trichoderma sp. endophyte isolates was analyzed using BLAST software. The results showed that Trichoderma sp. TM01 isolate had larger inhibitory than the other isolates on days 3 and 4 by 60% and 68%. TM01 isolate also showed inhibition to the growth of the G. boninense at 15% and 20%, with the percentage of inhibition reaching 71.79% and 82.05%. Based on phylogenetic analysis, the three endophytic isolates of Trichoderma sp. were closely related to Trichoderma virens.

Abstract

The crude polar extract of mangosteen fruit pericarp not only has a moderate antioxidant activity of (55±4 μg/mL) but also has high cytotoxicity (16±0.5 μg/mL). The high cytotoxicity presumably is caused by the presence of complex cytotoxic compounds from the mangosteen pericarp. To obtain a non-toxic extract preparation with high antioxidant activity, polar crude 50% ethanol extracts of mangosteen pericarp were partially purified using reverse-phase column chromatography with Silica C18 as the stationary phase and acetonitrile-water gradient elution. Six of the ten fractions collected had high antioxidant activities, with IC50 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging antioxidant levels <50 μg/mL. Three fractions (fractions 3, 5, and 7) with the highest antioxidant activities of (16.4 ± 0.6 µg/mL), (17.8 ± 2 µg/mL) and (17.4 ± 1.8 µg/mL) respectively, were chosen for further cytotoxicity, phenolic content and High-Performance Liquid Chromatography (HPLC) analysis. The cytotoxic tests were conducted with the Brine Shrimp Lethality Assay. Fraction 3 had low cytotoxicity (LC50 485 ± 96 µg/mL) and fraction 5 was non-toxic (LC50 ≥ 1000 µg/mL), while fraction 7 still had high cytotoxicity (LC50 2.8 ± 0.8 µg/mL). The chromatogram profiles of HPLC showed that fractions 3 and 5 contained more polar compounds than the compounds present in fraction 7. It can be concluded that the reverse phase method succeeded in the isolation of a non-toxic polar fraction, that is, fraction 5, with a significantly higher (p<0.05) antioxidant activity than in the original crude polar extracts. This fraction had a high total phenolic content of 43.3 ± 0.3 g GAE per 100 g extract.

Abstract

Penicillium sp. LBKURCC34 adalah jamur yang diisolasi dari tanah gambut hutan primer di Giam Siak Kecil Bukit Batu (GSKBB), Cagar Biosfer di Provinsi Riau. Tujuan dari penelitian ini adalah untuk mengeksplorasi potensinya sebagai penghasil antimikroba. Metode dilakukan melalui produksi metabolit sekunder dalam media cair, ekstraksi dalam larutan etil asetat, dan pemisahan ekstrak kasar dengan Kromatografi Kolom (CC). Ekstrak kasar dan fraksi diidentifikasi dengan KLT dan HPLC dan diuji aktivitas antimikrobanya dengan metode difusi cakram. Untuk mengidentifikasi senyawa aktif dilakukan uji fitokimia dan metode KLT-Bioautografi. Produksi tiga liter media menghasilkan 0,4 gram (0,0133% b/v) ekstrak etil asetat yang diidentifikasi sebagai terpenoid dan fenolat; dan mengandung senyawa semipolar berdasarkan uji KLT dan HPLC. Hasil KLT setelah disemprot dengan p-anisaldehida 0,5% menunjukkan adanya senyawa peptaibol (peptida). Ekstrak etil asetat dapat menghambat pertumbuhan kelima mikroba patogen yang diuji namun hanya 11-45% dibandingkan dengan kontrol positif. Uji bioautografi terhadap Escherichia coli menunjukkan noda aktif zona bening pada Rf sebesar 0,67. Sayangnya, dari Fraksi 1-5 yang terdapat noda dengan Rf 0,67 masih belum menunjukkan aktivitas berarti. Penyelidikan lebih lanjut diperlukan untuk mengidentifikasi struktur senyawa aktif dari isolat lokal ini.

Abstract

An antibiotic-resistant and multidrug-resistant (MDR) issue open the role of researchers to continue to search for natural potential as a source of new antimicrobials. One of the potential fungi isolates that can produce antimicrobial active compounds from Indonesian tropical peat soils is Penicillium sp. LBKURCC34. In this study, the production of antimicrobial compounds from local isolates was carried out by batch fermentation method in liquid media with the addition of biotic elicitors to increase the extraction activity and yield. This study aims to optimize the results based on the time the elicitor is added. Staphylococcus aureus was used as a biotic elicitor, which was added on days 2, 3, and 4 in the production of antibiotics by fermentation incubation of 6-14 days. The antibiotic production media was extracted with ethyl acetate and evaporated. The antimicrobial test was carried out by the disk diffusion method against pathogenic bacteria Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Staphylococcus epidermidis using three crude extract contents (19; 38; and 57 µg/disc). Amoxicillin® was used as a positive control (10 µL/disc). The results showed that the addition of S. aureus biotic elicitor extended the log phase growth of the fungus Penicillium sp. LBKURCC34. The optimum condition of production was obtained by adding initiator treatment on the 3rd day for 14 days incubation with the highest yield and could inhibit the growth of all pathogenic microbes.

Abstract

Reactive black 5 (RB5) is an azo dye widely used in the textile industry for dyeing fabrics. It is categorized as a recalcitrant dye that is hard to degrade and an environmental pollutant. Therefore, textile waste effluents containing this dye must be treated to remove or degrade the dye, before being released into the environment. One method that can be used to degrade synthetic dyes such as RB5 is to use biological methods, by directly using live fungal cells or using laccase enzymes. Trichoderma asperellum LBKURCC1 is a filamentous fungus isolated from cacao plantation soil in Riau, Indonesia, and it is a laccase enzyme producer. To be able to determine the ability of T. asperellum LBKURCC1 life cultures to decolorize RB5 dye, several RB5 dye removal tests were carried out. Incubation of 50 ppm RB5 with life cultures of T. asperellum LBKURCC1 at room temperature (30°C, pH 6.5) for 24 hours resulted in 22% bioremediation, 3.2% biosorption and 19.1% biodegradation of the RB5 dye.  The results of this study show that the live culture of T.asperellum LBKURCC1 is capable of biodegrading RB5. This is indicated by the degradation of RB5 by extracellular enzymes produced by these filamentous fungi.

Abstract

Penggunaan pigmen warna sintetis yang marak di industri tekstil, dikhawatirkan akan menimbulkan dampak lingkungan selama produksi maupun pengaplikasiannya. Limbah yang dihasilkan dari pigmen warna sintesis sulit didegradasi dan cenderung bersifat karsinogenik. Pigmen warna alami yang dihasilkan jamur Penicillium dapat menjadi solusi alternatif untuk mengatasi dampak lingkungan yang dihasilkan dari penggunaan pigmen warna sintesis tersebut. Penelitian ini bertujuan untuk menggali potensi isolat lokal Penicillium sp. LBKURCC27 sebagai sumber pigmen warna jingga alami dengan variasi pH media dan sumber nitrogennya. Penelitian dilakukan dengan memproduksi pigmen menggunakan isolat lokal Penicillium sp. LBKURCC27 pada media PDB dengan variasi pH (pH 4,5 hingga 7,5) dan variasi sumber nitrogennya (urea, tepung kedelai dan ekstrak ragi) pada suasana gelap dan statis selama 40 hari.  Hasil penelitian menunjukkan bahwa media produksi pada pH 5,5 menghasilkan jumlah pigmen yang secara signifikan (p<0,05) lebih tinggi dibandingkan dengan pH lainnya. Sumber Nitrogen berupa urea akan menghasilkan jumlah pigmen yang secara signifikan (p<0,05) lebih tinggi bila dibandingkan dengan sumber nitrogen berupa ekstrak ragi dan tepung kedelai. Hasil ekstraksi diuji menggunakan spektrofotometri UV-Vis untuk mengetahui panjang gelombang optimumnya sehingga diperoleh panjang gelombang 511 nm sebagai panjang gelombang optimum. Uji pewarnaan dilakukan dengan metode mordanting menggunakan mordant besi sulfat dan tawas yang menghasilkan kain berwarna coklat hingga jingga. Analisis kolorimetri juga dilakukan pada kain yang telah diwarnai sehingga diperoleh koordinat kromatis primer berupa RGB. Hasil pewarnaan kain dengan mordant besi sulfat memiliki warna yang lebih merata. Kain sutra memiliki warna yang lebih gelap dan lebih merata dibandingkan pewarnaan pada kain katun.
