Distribution of Clavibacter michiganensis subsp. michiganensis in Various Tomato Production Centers in Sumatra and Java
(IPB (Bogor Agricultural University), 2008)
Bacterial canker, caused by Clavibacter michiganensis subsp. michiganensis is a newly introduced disease of tomatoes in Indonesia. Its existence was first officially reported in 2004. The objective of this research was to ...
Cell Lysis Method Affects Assessment of Microbial Diversity Based on Ribotyping Analysis
(IPB (Bogor Agricultural University), 2008)
The microbial community in Kawah Hujan, Kamojang, West Java, Indonesia, was analyzed using 16S-rRNA-gene-sequencing combining with denaturing-gradient-gel electrophoresis (DGGE) technique. Two different cell lysis methods, ...
The Effect of Mutation at Thr 295 of Saccharomyces cerevisiae eRF1 on Suppression of Nonsense Codons and eRF1 Structur
(IPB (Bogor Agricultural University), 2008)
The termination of translation in Saccharomyces cerevisiae is controlled by two interacting polypeptide chain release factors, eRF1, and eRF3. Two regions in eRF1, at position 281-305 and 411-415, were proposed to be ...
Identity and Sequence Diversity of Begomovirus Associated with Yellow Leaf Curl Disease of Tomato in Indonesia
(IPB (Bogor Agricultural University), 2008)
Infection of tomato by Begomovirus is known to cause serious disease and yield losses. Samples of tomato plants showing typical symptoms of begomovirus infection were collected from eight locations in Java and Sumatra. ...
Ecological Approach to Unravel Streptomycete Diversity as an Unsurpassed Sources of Natural Bioactive Products
(IPB (Bogor Agricultural University), 2008)
Search and discovery for natural bioactive products have been so important to control the emergence of antibiotic resistant microbial pathogens. Therefore, novel microorganisms that produce such metabolites is extremely ...
Growth Responses of External Hyphae of Arbuscular Mycorrhizal Fungi to Acidic Soil Conditions and their Effects on Cowpea Growth
(IPB (Bogor Agricultural University), 2008)
The effectiveness of arbuscular mycorrhizal (AM) fungi has often been attributed to growth of their external hyphae, whilst the hyphae themselves may be subjected to the effects of severe soil conditions. The growth of ...
Recent Developments in the Bioconversion of Lignocelluloses into Ethanol
(IPB (Bogor Agricultural University), 2008)
Ethanol has been commercially produced using sugars derived from sugarcane and corn. Recently, research has been focused on the development of thermotolerant and ethanol-tolerant yeast or bacteria that are able to produce ...
Ecological Role of A Softcoral-Associated Bacterium Arthrobacter sp. on Marine Biofilm-Forming Bacteria
(IPB (Bogor Agricultural University), 2008)
A marine bacterium species associated with softcoral Sinularia sp. collected from vicinity of Peucang island, Ujung Kulon, West Java, was successfully screened for estimating its ecological role through inhibiting marine ...
Isolation and Identification of Ice-Nucleating-Active Bacteria from Indonesian Edible Leafy Plant Poh-Pohan (Pilea glaberina)
(IPB (Bogor Agricultural University), 2008)
Two ice-nucleating-active (INA) bacteria (isolates C and 6) were isolated from poh-pohan (Pilea glaberina), an Indonesian edible leafy plant (lalaban). The maximum nucleation temperature of aqueous suspensions of the two ...
Apparent Induction of Xylanase by Bacillus pumilus PU4-2 using Pretreated Substrates
(IPB (Bogor Agricultural University), 2008)
Bacillus pumilus PU4-2 produces xylanase (β-1,4-D-xylan xylanohydrolase; EC 3.2.1.8) in wheat pollard with high activity. Water and NaOH-soaked pollard were used in this research to enhance the production of assayable ...
