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 ...
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 ...
Activity of proteolytic and Amylolytic enzymes from Bacillus spp. Isolated from shrimp ponds
(IPB (Bogor Agricultural University), 2009)
Accumulation of feed excess in commercial shrimp ponds due to overfeeding could decrease water quality. Protein and starch are the primary components of shrimp feed. This study was conducted to characterize extracellular ...
Genetic Diversity of Plant Growth Promoting Rhizobacteria of Bacillus sp. Based on 16S rRNA Sequence and Amplified rDNA Restriction Analysis
(IPB (Bogor Agricultural University), 2009)
Plant-growth promoting rhizobacteria (PGPR) are rhizosphere associated soil-borne bacteria that can enhance plant growth and inhibit the development of root pathogens. Many soil bacteria have been used as PGPR, and one of ...
Effect of pH, Temperature and Medium Composition on Xylanase Production by Bacillus sp. AQ-1 and Partial Characterization of the Crude Enzyme
(IPB (Bogor Agricultural University), 2009)
Bacillus sp. AQ-1 was isolated from household aquarium sediment. The isolate produced extracellular xylanolytic enzymes on xylan containing agar medium. Based on morphological, and physiological analysis, the isolate was ...
Cloning of Genomic DNA Fragment Involve in Acid-Aluminium Tolerance in Bradyrhizobium japonicum 38 Through Transposom Mutagenesis
(IPB (Bogor Agricultural University), 2006)
An acid-aluminium sensitive mutant of Bradyrhizobium japonicum 38. designated as AAS38, was generated by mini-Tn5 transposon mutagenesis. The experiment was carried out to identify acid-aluminium tolerance gene (AAT) in ...
