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 ...
Utilization of root-colonizing bacteria to protect hot-pepper againts tobacco mosaic tobamovirus
(IPB (Bogor Agricultural University), 2007)
Tobacco Mosaic Tobamovirus (TMV) is one of many important viruses infecting Solanaceous plants including hot pepper in Indonesia. To accomplish and improve the effectiveness of virus management, we used root-colonizing ...
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 ...
Extracellular Protease Activity of Enteropathogenic Escherechia coli on Mucin Substrate
(IPB (Bogor Agricultural University), 2007)
Enteropathogenic Escherichia coli (EPEC) causes gastrointestinal infections in human. EPEC invasion was initiated by attachment and aggressive colonization on intestinal surface. Attachment of EPEC alter the intestine ...
ENERGI LISTRIK DARI SEDIMEN LAUT TELUK JAKARTA MELALUI TEKNOLOGI MICROBIAL FUEL CELL
(Masyarakat Pengolahan Hasil Perikanan lndonesia (MPHPI), 2011)
Sediment microbial fuel cell (SMFC) is one form of the microbial fuel cell (MFC) that can convert organic complex material in the sediment to generate electrons. This research was conducted to determine the characteristics ...
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 ...
The use of Acid-Alumunium tolerant bradyrhizobium japonicum inoculant for soybean grown on acid soils
(IPB (Bogor Agricultural University), 2009)
Land with low pH soil spread widely in Indonesia can be used for soybean (Glycine max) cultivation, although the production is low. The use of acid tolerant soybean and acid-Al tolerant nitrogen-fixing bacteria was an ...
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 ...
Screening and Characterization of Protease Inhibitors from Marine Bacteria Associated with Sponge Jaspis sp.
(IPB (Bogor Agricultural University), 2010)
Three isolates among 138 sponge-associated bacteria were isolated from Waigeo Island, Raja Ampat West Papua Province, Indonesia, have been shown protease inhibitory activity against subtilisin (serine protease), thermolysin ...
