Abstract

Penjalin water reservoir in Brebes Regency, Central Java, is one of the habitats of the sand goby. A study on its genetic diversity using approaches of isozyme analysis was needed to support domestication of the fish in this area. This study was aimed at the biochemical-genetic variation of sand goby population in Penjalin water reservoir based on esterase (EST), peroxidase (PER), malate dehydrogenase (MDH), aspartate amino-transferase (AAT), and acid phosphatase (ACP) polymorphisms. Visualization of the isozymes was carried out employing horizontal electrophoretic technique with potato starch gel and buffer system of L-histidin monohydrate. Of the five isozymes, ACP was not well-visualized in all samples tested while the remaining four showed no polymorphisms. It could be concluded that there is no biochemical-genetic variation of sand goby population in Penjalin water reservoir based on isozymes of EST, PER, MDH, and AAT.

Abstract

This research was done to study the adsorption kinetic of ferrous ionic by Chaetoceros sp. Many variables influenced the adsorption capacity of absorbent on ferrous ionic including interaction time, ferrous ionic concentration and pH. Two absorbens were used in this study i.e. pure culture and natural spoiled product called Diatomite/ Diatomae earth / Diatomaceous earth / Diatomooze of Chaetoceros sp. biomass. The adsorption capacity by biomass was measured by atomic absorption spectrophotometry method (AAS). The result showed that the adsorption process of two absorbents happened very fast. The time needed to get maximal adsorption were 10 and 15 minutes respectively. Adsorption pattern of two biomass can be interpreted by Langmuir and Freundlich isoterm showing monolayer. The adsorption capacity of Diatomite was five times higher than that of the pure culture biomass because it was influenced by surface group charge and wide surface area of porous. Acidity degree (pH) of solution determined surface active group charge and solubility of iron (II). The increased pH value, the biomass adsorption capacity was added because surface active group had negative charge. The adsorption of biomass was maximal around pH 5 while for pH higher than 5, it wasn’t significantly increased because the iron (II) formed insoluble hydroxide compound.

Abstract

Information on ability of Aspergillus niger to secrete organic acid is important in using A. niger as phosphate rock-solubilizing microorganism. This research was aimed to examine the ability of A. niger YD 17 secreting organic acid when it was grown with phosphate rock. An A. niger YD 17 was obtained from Laboratory of Microbiology, Faculty of Agriculture, GMU. The phosphate rock used was Christmas Island phosphate rock. Organic materials consisted of tapioca waste industry, rice bran, and starch. The study was conducted in Pikovskaya liquid medium and soils that were taken from Jasinga, Banten, West Java (ultisol) and Karang Jati, Ungaran, Central Java (inceptisol). The type and level of organic acid production were determined using high performance liquid chromatography (HPLC). The results indicated that A. niger YD 17 was able to secrete organic acid when it was grown with phosphate rock. The level of organic acid in the Pikovskaya liquid medium reached 255.7 g.ml-1, whereas in the soil reached 2992.5 g.g-1. Malate dominated organic acid in the Pikovskaya liquid medium, while in the soils dominated by oxalate. The type and level of organic acid secreted by A. niger YD 17 were influenced by carbon and phosphorus sources, concentration of inoculums, and characteristic of the soils.

Abstract

Odour and frequently visited plants by Bactocera sp. were screened for fruit fly attractants. The attractiveness of hexane extracts for B. dorsalis were determined by Y-tube method. Of 20 species treated, 5 species such as Cymbopogon nardus, Ocimum basillicum, Cymbopogon citratus, Cananga odorata, and Hyptis suaveolens showed the attractiveness and the presence of methyl eugenol (ME). These plants could be used as the source of ME for controlling fruit flies infestation. It was also found that Ruta graveolens (Rutaceae) revealed the absence of ME peak by GC-spectrum but responded to fruit flies B. carambolae. The results reveal that the chemical compounds existing in the extracts of R. graveolens may have great potential for development as attractants of the Oriental fruit fly. However, further isolation, identification, and evaluation of active compounds are needed in future studies.

Abstract

Karakterisasi molekuler anjing Kintamani berperan penting dalam penentuan status trah dan mencegah penurunan kemurnian akibat perkawinan silang dengan trah anjing lain. Anjing Kintamani sangat popular di Bali. Anjing Kintamani dipercaya berasal dari Kintamani, Bangli, tetapi asal usulnya sampai kini belum jelas. Mikrosatelit merupakan runutan nukleotida terulang yang didistribusikan secara acak dalam gen vertebrata. Lokus mikrosatelit ini telah diketahui sangat polimorfik, karena keragaman jumlah nukleotida yang terulang. Mikrosatelit merupakan petanda allel utama yang dapat digunakan untuk pemetaan gen, genetika populasi dan identifikasi individu serta alat untuk mengungkap karakter genetik hewan. Pada penelitian ini diungkap karakteristik genetik anjing Kintamani menggunakan mikrosatelit. Jumlah dan ukuran allel pada 425 anjing Kintamani dianalisis menggunakan 116 macam primer mikrosatelit. DNA diisolasi dari sel hasil swab pipi. Amplifikasi 116 lokus mikrosatelit menggunakan PCR dalam 12 multiplek. Produk PCR dipisahkan dengan gel bis-akrilamid 6% dalam automated DNA sequencer. Flurosesnsi yang dihasilkan dideteksi dengan program Genescan 3.1, dan program Strand versi 2.2.39 digunakan untuk menghitung jumlah allel. Hasil penelitian menunjukkan bahwa jumlah allel yang didapat adalah 1128. Jumlah allel perlokus berkisar antara 3 (AHT136) sampai 41 (FH2138). Rataan PIC adalah 0,68 dan semua lokus bersifat polimorfik.

Abstract

Plant cell walls are unique, complex, diverse and dynamic structures that change throughout the process of cell division, growth and differentiation. Plant cell walls are not only a single key determinant of overall plant form, but they also play an important role in sustaining human societies. Evidence of how cell walls are crucial for plant structure is that without cell walls, plants would be elastic piles of protoplasm, more like slime moulds than stately trees. Unlike animals, in which specialized skeletal system provides physical support, the strength, flexibility, texture and overall shape of higher plants depend on the cumulative properties of walls. Moreover, plants are composed of approximately 35-40 cell types that are distinguished from each other by the chemistry and organization of their walls. In human societies, cell walls directly affect the quality of most plant-based products, including paper and pulping, textile, food quality and texture, dietary fibre, malting and brewing and bioethanol production (Cosgrove, 2005; Farrokhi et al., 2006).The chemical structure of most wall components has been intensively studied and defined in detail, however, the enzymes responsible for cell wall biosynthesis and also its restructure remain poorly understood. However, currently, there has been real progress towards understanding the cell wall biosynthesis, using various emerging approaches, such as genetic and biochemical approaches (Farrokhi et al., 2006).This review will elaborate on recent advances in our knowledge of the structure cell walls of flowering plants, particularly the structure of primary cell walls. Moreover, this review will also explain the current knowledge towards understanding primary wall biosynthesis and also the future application of cell wall study in biotechnology.
