Abstract

Indentification of Entomopathogenic Red Bacterial fromBrown Planthopper (Nilaparvata lugens Stål.). Tri P.Priyatno, Yohana A. Dahliani, Yadi Suryadi, I MadeSamudra, Dwi N. Susilowati, Iman Rusmana, Baskoro S.Wibowo, and Cahyadi Irwan. Red bacteria isolated frombrown planthopper (BPH) has been proven pathogenicagainst BPH and others insects. Application of 106 to 107cells/ml of red bacteria caused 65.6-78.2% mortality of BPH.The 50% effective concentration (EC50) and lethal time of redbacteria against BPH is 2.8 x 105 cells/ml and 6.8 days,respectively. Based on phenotypic characters tested on GNMicroPlateTM Biolog kit and 16S rRNA sequneces analysis,red bacteria was identified as Serratia marcescens with 99%similarity. Red pigmen produced by S. marcescens strainBPH is secondary metabolite determined as prodigiosinshowing bactericidal activities against Xanthomonas oryzaepv. oryzae. We concluded that S. marcescens did not onlypotent as biocontrol agent to BPH, but also it can be used tocontrol plant pathogenic bacteria.

Abstract

Prodigiosin, the red pigment producedby the bacterium Serratia marcescens, is a secondarymetabolite of the family tripyrrole that has been widely usedas an antibiotic in the multifunction treatment ofantibacterial as well as antifungal. This study was aimed tostudy the effect of Luria-Bertani (LB) broth and nutrientbroth (NB) media suplemented with several concentrationsof FeSO4 and CaCO3 on the production and characteristic ofprodigiosin derived from S. marcescens. The study wasarranged in a completely randomized factorial design withfour replications. The LB and NB media were supplementedwith 0, 2.5, 5, and 10 mM CaCO3 and 0, 0.25, 0.5, and 1 mMFeSO4. Results showed a red pigment produced by S.marcescens when cultured on both LB and NB media. Redlikepigmentation was varied when supplemented withdifferent concentration of Fe2+ and Ca2+. The higher theconcentration of Fe2+, the more intense the red color,conversely, the higher the concentration of Ca2+, the lighterthe red color. The interaction was found between the mediaand concentrations of CaCO3 and FeSO4 on the productionof prodigiosin. The highest prodigiosin production wasobtained on NB media supplemented with FeSO4.Meanwhile, the addition of CaCO3 did not affect theprodigiosin production. An addition of 1 mM FeSO4 to LBand NB media produced crude prodigiosin of 486.0 mg/mland 489.0 mg/ml, respectively. Based on purification bycolumn chromatography using silica gel, the prodigiosinproduction on LB and NB media was 378 mg/ml and 450mg/ml, with the purity level of 77.8% and 92%, respectively.Detection of prodigiosin by thin-layer chromatography usingsilica gel showed the red pigment had Rf value of 0.83 andbioautography assay showed there was an antibacterialactivity against Xanthomanas oryzae pv. oryzae.

Abstract

Ekspresi gen-gen virulensi pada Dickeya dadantii diatur oleh proses quorum sensing menggunakan asil-homoserin lakton (AHL) sebagai molekul sinyal. Patogenisitas bakteri tersebut dapat dihambat oleh aktivitas quorum quenching (QQ) bakteribakteri penghasil AHL-laktonase. Tujuan penelitian ini adalah mengisolasi dan mengarakterisasi bakteri penghasil AHLlaktonase asal rizosfer dan filosfer yang berpotensi untuk dikembangkan sebagai quorum quencher untuk D. dadantii. Isolasi bakteri dilakukan dari sampel daun dan sampel tanah rizosfer beberapa komoditas tanaman asal Sukabumi, Tegal, Kupang, dan Wonosobo. Sebanyak 8 dari 79 isolat bakteri yang diperoleh menunjukkan aktivitas QQ terhadap bioindikator Chromobacterium violaceum. Bioasai respons hipersensitif (hypersensitive response) yang dilakukan pada tanaman tembakaumenunjukkan enam (KT2, KT9, KT10, KUT1, TKF2, and WKF3) dari delapan isolat tersebut tidak menimbulkan respons hipersensitif. Keenam isolat tersebut mampu menekan virulensi D. dadantii pada umbi kentang. Sekuen 16S rRNA enam isolat tersebut memiliki kemiripan tertinggi dengan Bacillus cereus, B. aryabhattai, B. acidiceler, dan Micrococcus aloeverae. B. cereus KT9 and B. aryabhattai TKF2 terdeteksi memiliki gen penyandi AHL-laktonase (aiiA). Ini merupakan laporan yang pertama tentang aktivitas QQ pada spesies M. aloeverae, B. aryabhattai, and B. acidiceler. Keberadaan gen aiiA pada B.aryabhattai juga belum pernah dilaporkan sebelumnya. Penelitian ini memberikan informasi baru tentang aktivitas QQ ketiga isolat tersebut dan potensinya sebagai quorum quencher untuk D. dadantii.
