The Impact of Human Activities to Dynamic of Insect Communities: a Case in GUnung Salak, West Java
(IPB (Bogor Agricultural University), 2010)
Huge areas of diverse tropical forest are lost or degraded every year with dramatic consequences for biodiversity. Human activities such as deforestation, fragmentation, over-exploitation, and monoculture practices are the ...
Characterization of Endophytic Diazotroph Bacteria Isolated from Rice
(IPB (Bogor Agricultural University), 2010)
Attempt to extend the biological nitrogen fixation to important crops such as rice has been conducted by isolating endophytic diazotrophs from rice rhizosphere and roots. In this study, three bacterial isolates of R2, R4, ...
Morphological Characteristic of Ectomycorrhizas on Merbau [Intsia bijuga (Colebr.) O. Kuntze]
(IPB (Bogor Agricultural University), 2010)
Merbau [Intsia bijuga (Colebr.) O. Kuntze] is one of valuable timber tree in south-east Asia which has been known having ectomycorrhizae (EcM) though being ignored. Identification of the ectomycorrizae is prime important ...
Intracellular CA 2+ Regulation in Calcium Sensitive Phenotype of Saccharomyces cerevisiae
(IPB (Bogor Agricultural University), 2010)
Intracellular cytosolic Ca2+ concentration accumulation plays an essential information in Saccharomyces cerevisiae i.e. to explain cellular mechanism of Ca2+ sensitive phenotype. Disruption both S. cerevisiae PPase PTP2 ...
Sequence Characterized Amplified Region (SCAR) Markers in Sengon (Paraseriathes falcataria (L.) Nielsen)
(IPB (Bogor Agricultural University), 2010)
Genotype identification of Sengon (Paraseriathes falcataria (L.) Nielsen needs accurate and reliable method for identification. Sixteen individuals of P. falcataria from Okinawa, Japan were used as materials for selecting ...

Structural Analysis of Xylanase from Marine Thermophilic Geobacillus stearothermophilus in Tanjung Api, Poso, Indonesia
(IPB (Bogor Agricultural University), 2010)
A xylanase gene, xynA, has been cloned from thermophilic strain Geobacillus stearothermophilus, which was isolated from marine Tanjung Api, Indonesia. The polymerase chain reaction product of 1266 bp of xynA gene consisted ...
Root and Nodulation Phenotypes of the Ethylene-Insensitive Sickle Mutant of Medicago truncatula
(IPB (Bogor Agricultural University), 2010)
The sickle (skl) mutant of the model legume Medicago truncatula is an ethylene-sensitive mutant that have a ten-fold increase in nodule numbers. The nodulation and root phenotypes of the skl mutant were investigated and ...
Inhibition of Urokinase-Type Plasminogen Activator Expression by Macelignan in Porphyromonas gingivalis Supernatant-Induced Human Oral Epithelial Cells
(IPB (Bogor Agricultural University), 2010)
This study was to investigate the effect of macelignan on Porphyromonas gingivalis supernatant-induced uPA expression via regulating mitogen-activated protein kinase (MAPK) and activating protein-1 (AP-1) signaling pathways ...
Primary Nutritional Content of Bio-Flocs Cultured with Different Organic Carbon Sources and Salinity
(IPB (Bogor Agricultural University), 2010)
Application of bio-flocs technology (BFT) in aquaculture offers a solution to avoid environmental impact of high nutrient discharges and to reduce the use of artificial feed. In BFT, excess of nutrients in aquaculture ...
