Hydrolysis Methods of Starch for Culture Media of Bacillus sp. BMN14 Producing Biosurfactant Lipopeptide
(IPB (Bogor Agricultural University), 2000)
Ezymatic and acid hydrolysis of starch for culture media of Bacillus sp. BMN14 producing lipopeptide blosurfactant were studied using cassava, arrowroot and sago starch. These starch bydrolysates were used as glukose ...
The Selection of Xylanase-Producing Indegenous Bacteria
(IPB (Bogor Agricultural University), 2000)
The isolation and selection of xylanase producing bacteria have been done from soil and waste of starch Industry. Strains were cultivated in neutral and alkaline media with xilan as a substrate. Colonies which produced ...
Fed-Batch Fermentation Processes to Produce dextranase fro of Streptococcus sp.B7
(IPB (Bogor Agricultural University), 1999)
The research aimed to develop fermentation technique on dextranase production from the bacterial isolate of Streptococcus sp. B7 using fed-batch Fermentation system. The production was done in two litre Fermentor with flow ...
Root Colonization and Symbiotic Effectiveness of Acid Tolerant and Acid Sensitive Strains of Bradyrhizobia in Acid Soils
(IPB (Bogor Agricultural University), 2000)
Acid soil is characterized by numerous growth limIting factors. Low pH may reduce the availability of element such as Ca, Mg, P and Mo, and increase the availability of Al and Mn, limiting plant growth and survival and ...
The Diversity Analysis of Moulds Contaminating Commercial Poultry Feed
(IPB (Bogor Agricultural University), 2000)
Samples of poultry feed were collected from several poultry shops around Jakarta, Bogor, and Bandung, which represented different location altitudes. Samples were inoculated onto Sahouraud's glucose agar then incubated at ...
Development of Rapid Agglutination Test to Detect Chicken Marek Antibody
(IPB (Bogor Agricultural University), 2009)
To our knowlege, there is no rapid agglutination test to detect antibodies to viruses which might be due to the small dimension of viral particles. Through complex formation of Staphylococcus aureus bearing protein A-rabbit ...
The Production of Nata Colored by Monascus Purpureus J1 Pigments as Functional Foods
(IPB (Bogor Agricultural University), 2010)
Pigmen from Monascus sp. may color nata. The mold also produces monacolin K that inhibits HMG-CoA reductase affecting the reduction of blood cholesterol. The aim of this study was to produce the colored nata containing ...
Perpustakaan Gen: Bagaimana Mengonstruksinya?
(IPB (Bogor Agricultural University), 2001)
Many methods can be used to construct genomic DNA library in the cosmid vector. In this system, large fragments of genomic DNA generated by randomly digestion are ligated to the cosmid vector to form concatemers that can ...
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 ...
Characterization of Bacillus sp. strains isolated from rhizosphere of soybean plants for their use as potential plant growth for promoting Rhizobacteria
(IPB (Bogor Agricultural University), 2011)
Rhizobacteria of Bacillus species were isolated from the rhizosphere of soybean plant of Cirebon, Indonesia, and further examined for plant growth promoting activities. A total of 118 isolates identified as Bacillus sp., ...
