Abstract

A random amplified polymorphic DNA (RAPD) marker linked to powdery mildew resistance gene (Pm-I) in melon PI 371795 was reported. However, the RAPD marker has problem in scoring. To detect powdery mildew resistance gene (Pm-I) in melon accurately, the RAPD marker was cloned and sequenced to design sequence characterized amplified region (SCAR) markers. SCAPMAR5 marker derived from pUBC411 primer yielded a single DNA band at 1061 bp. Segregation of SCAPMAR5 marker in bulk of F2 plants demonstrated that the marker was co-segregated with RAPD marker from which the SCAR marker was originated. Moreover, results of SCAR analysis in diverse melons showed SCAPMAR5 primers obtained a single 1061 bp linked to Pm-I in resistant melon PI 371795 and PMAR5. On the other hand, SCAPMAR5 failed to detect Pm-I in susceptible melons. Results of this study revealed that SCAR analysis not only confirmed melons that had been clearly scored for resistance to Pm-I evaluated by RAPD markers, but also clarified the ambiguous resistance results obtained by the RAPD markers.   Key words: Cucumis melo L., Pm-I, RAPD, SCAPMAR5

Abstract

Genetic relatedness among duku, kokosan, and pisitan from Indonesia were investigated using random amplified polymorphic DNA (RAPD) markers. Eleven primers (OPA-01, OPA-02, OPA-10, OPB-07, OPB-11, OPB-12, OPB-15, OPT-16, OPU-14, OPU-19, and OPU-20) were used for amplification and yielded a total of 174 DNA bands, of which 167 were polymorphic. Primer OPA-10, OPB-11, OPB-12, OPB-15, and OPU-19 produced all of the polymorphic DNA bands. The size of the amplified DNA fragments ranged from 41-1546 bp. The dendrogram separated into two clusters at a genetic similarity coefficient of 0.76. The cluster 1 consisted of subclusters duku and several pisitan (pisitan OKI, pisitan Sleman, pisitan Hatu, pisitan Punggur, and pisitan Tanjung), and cluster 2 consisted of subclusters kokosan and pisitan. In the kokosan subclusters, including duku Drendan. Dendrogram supported the determination of taxonomic status of duku, kokosan, and pisitan as one species, namely Lansium domesticum Corr. and its divided into two groups, namely L. domesticum ’duku group’ and L. domesticum ’pisitan-kokosan group’. Thus, RAPD analysis was useful tool for determining the genetic variation and the genetics relatedness among duku, kokosan, and pisitan in Indonesia.Key words: duku, kokosan, pisitan/langsat, genetic relatedness, RAPD

Abstract

Fungi are capable of treating various synthetic dye effluents. Previously, we isolated seven strains of fungi from contaminated batik dye effluent at Banyumas, Central Java. The aims of this study were to screen the ability of these fungi to decolorize batik dye effluents containing Indigosol Blue-04B and to investigate the phytotoxicity effects of biodegraded effluent on the germination of corn seeds Zea mays L. and green bean seeds Vigna radiata (L.) Wilczek. In addition, the decolorized effluents were tested for toxic effect on the agriculturally important gram-positive and gram-negative soil bacteria Bacillus cereus and Azotobacter sp., Staphylococcus aureus and Escherichia coli, respectively. Study of decolorization showed that fungi were able to decolorize Indigosol Blue-04B batik dye effluents by 21.04% to 99.89% at room temperature after three days of incubation. The assay of phytotoxicity showed that both plumule and radicle length of Z. mays and V. radiata grown on the decolorized effluent was longer than on untreated effluent. The percentage of Z. mays and V. radiata seed germination in decolorized effluent was higher than in untreated effluent. There was no inhibition zone found around the decolorized effluent samples after incubating the bacteria for 48 hours. Aspergillus sp. 3 was the most effective for degradation and could be used for batik effluent mycoremediation processes.

Abstract

ENZYMATIC CELL DISRUPTION OF MICROALGAE USING CELLULASE. Micro-algae is one source of potential alternative energy of third generation to be developed as bioethanol raw material. The starch content trapped in Micro-algae cell walls causing the need of cell distruption to release and convert starch into simple glucose before the fermentation process. This study aims to open up the cell walls of Micro-algae and to explore the effect of sellulase enzymes from Aspergillus niger as Micro-algae cell distruption strategy as well as the optimization of process parameters, i.e the concentration of enzyme, temperature, pH, and time which produce the highest glucose yield. The results showed that the highest glucose yield was 82.44% (w/w) obtained at an enzyme concentration of 30% (w/w), temperature 45oC, pH of 4.5 at 40 minutes, the amount of Micro-algae as 0.5 g/L. In general, cell distruption method using sellulase enzyme was proven to be a promising option to open the cell walls of Micro-algae and convert cellulose into simple glucose simultaneously in producing bioethanol.   Keywords: bioethanol; cellulose; cell distruption; enzymatic; micro-algae; starch Abstrak Mikroalga merupakan salah satu sumber energi alternatif generasi ketiga yang potensial untuk dikembangkan sebagai bahan baku bioetanol. Kandungan pati yang terperangkap dalam dinding sel mikroalga menyebabkan perlunya cell distruption untuk melepaskan sekaligus mengkonversi pati menjadi glukosa sederhana sebelum proses fermentasi. Penelitian ini bertujuan untuk membuka dinding sel mikroalga sekaligus mengeksplorasi pengaruh enzim sellulase dari aspergillus niger sebagai strategi cell distruption mikroalga serta melakukan optimasi parameter proses yaitu konsentrasi enzim, suhu, pH, dan waktu yang memberikan yield glukosa tertinggi. Hasil penelitian menunjukkan bahwa yield glukosa tertinggi adalah 82,44% (w/w) yang diperoleh pada konsentrasi enzim 30% (w/w), suhu 450C, pH 4,5 pada waktu 40 menit, dengan jumlah mikroalga 0,5 g/L. Secara umum, metode cell distruption dengan menggunakan enzim sellulase terbukti menjadi pilihan yang menjanjikan untuk membuka dinding sel mikroalga sekaligus mengkonversi selulosa menjadi glukosa sederhana dalam memproduksi bioetanol.

Abstract

The previous studies showed that the Albertisia papuana Becc. root have cytotoxicity on breast cancer. The A. papuana root toxicity on breast cancer could not only by plant secondary metabolism, but may be also by secondary metabolism of endophytes. Aspergillus fumigatus is one of endophytes that have anticancer agent. Endophytes can be distributed dynamically in whole of plant organ, one of them are leaves. Therefore the objective of this studies were to know the presence of A. fumigatus in A. papuana leaves, and the cytotoxicity of their secondary metabolism on breast cancer cells. The sample of A. papuana were collected from Botanical Zoo of Bogor, while T47D and MCF-7 cell lines were obtained of Tropical Medicine’s Faculty, UGM. Isolation of endophytes was done by growing leaves extract on water agar 2 % medium. Secondary metabolism was extracted from fermented broth using in ethyl acetat and n-butanol. The cytotoxicity was perform by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. The result showed that A. fumigatus assosiated with A. papuana leaves. Ethyl acetat extract from fermented A. fumigatus both on T47D and MCF-7 cell lines had lower (IC50. 50, 444 µg/ml and 59 µg/ml) than n-butanol (IC50. 103, 398 µg/ml and 127,188 µg/ml. It could be said that A. fumigatus from A. papuana leaves could induce cytotoxicity on T47D and MCF-7 breast cancer cells.
