Evidence for a Link Between Pathogenicity and the Role of Imp Bacterial Transport Effector Proteins in Soybean Infection by Xanthomonas axonopodis pv. glycines Vol 1, No 2, 2007
(Bogor Agricultural University, 2007)
Xanthomonas axonopodis pv. glycines (Xag) is the causal agent at bacterial pustule disease of soybeans. A non-¬pathogenic mutant of Xag (M715) was constructed employing transposon mutagenesis which showed similar epiphytic ...
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 ...
The Process of Xylanase Production from Bacillus pumilus RXAIII-5
(IPB (Bogor Agricultural University), 2007)
The optimum conditions for the growth of Bacillus pumilus RXAIII-5 (a potential xylanase producer) were sought, these included temperature, pH, aeration, and agitation of the culture batch. Afterwards a mathematical model ...
Formation and Pathogenicity Variation of Oospores of Phytophthora capsici Infecting Black Pepper
(IPB (Bogor Agricultural University), 2007)
Phytophthora capsici Leonian is the causal agent of foot rot disease of black pepper (Piper nigrum L.). Foot rot disease is the most destructive disease which can cause significant economic losses of black pepper. Two ...
The Production of Tannin Acyl Hydrolase from Aspergillus niger
(IPB (Bogor Agricultural University), 2007)
The aim of this research was to produce tannin acylhydrolase (tannase) from Aspergillus niger isolated from cacao pod. The first step of the study included determination of optimal pH, temperature, and incubation period ...
Immunological Detection of Avian Influenza Virus in Infected Ducks by Monoclonal Antibodies Against AIV-H5N1
(IPB (Bogor Agricultural University), 2007)
In order to establish a detection method for avian influenza virus (AIV) infection in ducks, monoclonal antibodies (MAbs) against the virus were produced. The virus used for the production of the monoclonal antibodies was ...
Mutation and Characterization of an Albino Mutant of Monascus sp. Isolated from the Cikapundung River, Bandung
(IPB (Bogor Agricultural University), 2007)
Monascus sp. isolated from Cikapundung River, Bandung was mutated using ethyl methanesulfonate (2.5%, 90 min). Previously, this wild type was identified as Monascus purpureus ITBCC-HD-F001 employing random amplification ...
Identification of Class 1 Integron of Escherichia coli from Street Foods in Jakarta
(IPB (Bogor Agricultural University), 2007)
A total of 43 Escherichia coli isolates were identified from school street foods located in Northern and Southern Jakarta. The isolates were examined for antibiotic resistance using five antibiotics discs (ampicillin, ...
Rapid and Simple Amplification of Genomic DNA Sequences Flanking Transposon
(IPB (Bogor Agricultural University), 2007)
A rapid and simple method to amplify genomic DNA sequences flanking mini-Tn5 transposon insertion was developed. This technique can be used to determine the location and orientation of the transposon insertion within genomic ...
Screening of Proteolytic Enzymes of Streptomyces sp. Local Strain and Their Characterization
(IPB (Bogor Agricultural University), 2007)
Protease of two Streptomyces sp. strain were chosen for characterization because of the large clear zone surrounding the colony in nutrient agar media containing 1% (w/v) skim milk. Extracellular protease from the two ...
