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 ...
Membrane Topology of Subunit 8 Variant of Yeast Saccharomyces cerevisiae Mitochondrial ATP Synthase
(IPB (Bogor Agricultural University), 2009)
The yeast mitochondrial F1F0-ATP synthase is a multisubunit complex that contains at least 17 different subunits. Subunit 8 of yeast mitochondrial ATP synthase is a hydrophobic protein of 48 amino acids encoded by the ...
Ecological Approach to Unravel Streptomycete Diversity as an Unsurpassed Sources of Natural Bioactive Products
(IPB (Bogor Agricultural University), 2008)
Search and discovery for natural bioactive products have been so important to control the emergence of antibiotic resistant microbial pathogens. Therefore, novel microorganisms that produce such metabolites is extremely ...
Growth Responses of External Hyphae of Arbuscular Mycorrhizal Fungi to Acidic Soil Conditions and their Effects on Cowpea Growth
(IPB (Bogor Agricultural University), 2008)
The effectiveness of arbuscular mycorrhizal (AM) fungi has often been attributed to growth of their external hyphae, whilst the hyphae themselves may be subjected to the effects of severe soil conditions. The growth of ...
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 ...
Horizontal Transfer of the “Popcorn-Effect” Strain of Wolbachia from Drosophila melanogaster to Stomoxys calcitrans
(IPB (Bogor Agricultural University), 2009)
The Wolbachia containing haemolymph from Wolbachia infected Drosophila third/fourth instar larvae was transferred through microinjection into 5-days-old pupae of the blood sucking stable fly, Stomoxys calcitrans. There was ...
The Antimutagen Capacity of Synthesized Polyphenol Glycoside through Transglycosylation by CGTase Enzyme of Bacillus polymyxa D4
(IPB (Bogor Agricultural University), 2001)
Polyphenol gycoside was synthesized through enzimatic trausglycosylation by cyclodeztrin glucanotransferase I1.4-a-D-glucan 4-cz-D-1,4-glucano-transfcrssc or CGTase EC 2.4.1.19, of Bacillus poly,nyxa D4. Soluble starch and ...
Antimicrobial Activity of Black Cumin Extracts (Nigella sativa) Against Food Pathogenic and Spoilage Bacteria
(IPB (Bogor Agricultural University), 2009)
This study aimed to analyze the antimicrobial activity of black cumin (Nigella sativa) extracts in inhibiting the growth of pathogenic and spoilage bacteria. Black cumin was extracted by using steam distillation, single ...
Recent Developments in the Bioconversion of Lignocelluloses into Ethanol
(IPB (Bogor Agricultural University), 2008)
Ethanol has been commercially produced using sugars derived from sugarcane and corn. Recently, research has been focused on the development of thermotolerant and ethanol-tolerant yeast or bacteria that are able to produce ...
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 ...
