Isolation and Identification of Mycorrhizospere Bacteria and Their Antagonistic Effects Towards Ganoderma boninense in Vitro
(IPB (Bogor Agricultural University), 2010)
Basal stem rot caused by Ganoderma boninense is the most serious disease of oil palm (Elaeis guineensis) in Indonesia and it has caused major loss in palm oil production. Mycorrhizospere bacteria offer possible advantages ...
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, ...
Chitinolytic Bacteria Isolated from Chili Rhizosphere: Chitinase Characterization and Application as Biocontrol for Aphis gossypii
(IPB (Bogor Agricultural University), 2010)
Chitin, a common constituent of insect exoskeleton, could be hydrolyzed by chitinase. This research was conducted to select rhizobacteria isolated from the rhizosphere of chili pepper that produced chitinase and to examine ...
The use of ion exchange chromatography of DEAE-sepharose CL-6B in the puricication of cellulase from cellulomonas CSI-17
(IPB (Bogor Agricultural University), 1999)
Ion exchange chromatography of DE.AE-sepharose CL-6B was used to purify cellulase components from a culture filtrate of Ceiiuiomonas CSI-17 grown on microcrystalline cellulose Sigmaeell-20. The cellulase components were ...
Biodegradability ofAliphatic Polyester
(IPB (Bogor Agricultural University), 2000)
The presence of microbes which can degrade commercial biodegradable plastics, i.e. poly-c-caprolactone PCL, poly-.hydroxy butyrate PUB, polybutylene succinate PBS and polylactic acid PLA, was e'aluated using colony counting ...
Characterization of Acid-Aluminium Sensitive Mutants of Soybean Symbiont Bradyrhizobium japonicum Generated by Transposon Mutagenesis
(IPB (Bogor Agricultural University), 2007)
Acid-aluminium sensitive mutants of symbiotic bacterium Bradyrhizobium japonicum BJ11 (designated as AAS11) and KDR15 (designated as AAS15) were constructed by mini-Tn5 transposon mutagenesis to study genes involved in ...
Purification ofct-Amylasefrom Bacillus stearothermophilus by Ultrafiltration Membrane
(IPB (Bogor Agricultural University), 2000)
The objective of this experiment was to evaluate the optimum conditions of cc-amylase of Bacillus slearotherinophilus purification by ultrafiltration and the step of a-amylase purification from indigenous isolate. Culture ...
Survival Mechanism of Puccinia abrupta var. partheniicola Urediniospores During Summer Season
(IPB (Bogor Agricultural University), 2009)
The success of applying plant pathogens as biological control agents of weeds relies on the ability of the biological control agent to persist at all parts of the year and to successfully go through all of its life cycle ...
Application of Numerical Systematics in Unraveling Streptomycete Diversity
(IPB (Bogor Agricultural University), 2001)
Systematic play an important role in the utilization of streptomycete strains as an outstanding producer of thousands documented bloactive compounds. The chaotic state of streptomycete systematics resulted from the appli ...
Molecular Detection of Dapsone and Rifampicin Resistance on Mycobacterium leprae from Leprosy Patients in East Java
(IPB (Bogor Agricultural University), 2009)
The drug resistant problem of Mycobacterium leprae has been developing since the last decade and this has become a leprosy elimination problem in several countries, including Indonesia. Using biological on molecular methods, ...
