Formation and Pathogenicity Variation of Oospores of Phytophthora capsici Infecting Black Pepper
(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 ... -
Fragnance Formation in Aquilaria spp. Shoot Culture Induced by Acremonium sp.
(2010)In this research, fragnance formation in the shoot culture of three clones of Aquilaria malaccensis (Amal, Ama7 and Ama13) and four clones of A. microcarpa (Ami5, Ami8, Ami16 and P6) as a response towards infection of four ... -
Free-Living Ice-Nucleating Active Bacteria from High Mountain Lake Habitats
(2008)We collected the culturable heterotrophic bacteria from oligotrophic high mountain lake habitats and tested their capability to induce ice formation. Direct plating was carried out using low-nutrient medium at a temperature ... -
Generation and Characterization of Temperature Resistant Mutant of Recombinant PJ156/CAV-17 Virus
(2007)Previous study revealed that a recombinant virus between poliovirus (isolate PJ156) and coxsackie A virus serotype 17 (CAV-17), namely PJ156/CAV-17, was temperature sensitive. It is well known that two amino acids in 3D ... -
Genetic Diversity of Antifungi-Producing Rhizobacteria of Pseudomonas sp. Isolated from Rhizosphere of Soybean Plant
(2010)Antifungi-producing rhizobacteria have been regognize playing an important role in plant desease supression. In our laboratory, 13 indigenous soybean rhizobacteria Pseudomonas sp. that showed strong growth inhibition of ... -
Genetic Diversity of Osmophilic Yeasts Isolated from Indonesian Foods with High Concentration of Sugar
(2010)Isolation of osmophilic yeasts from a total of 70 samples consisting of jam, sweet condensed milk, honey, sweet soy sauce, and palm sugar was conducted. Sixty-eight osmophilic yeasts were isolated from strawberry jam, ... -
Genetic Diversity of Plant Growth Promoting Rhizobacteria of Bacillus sp. Based on 16S rRNA Sequence and Amplified rDNA Restriction Analysis
(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 ... -
Genetik Diversity of Yeast From Fermented Orange Juice Based on PCR-RFLP and Sequence Analysis of The Internal Transcribed Spacer Region
(2010)Orange is one of the most valuable and common fruites in Indonesia, High glucose level in orange juice provides good growth conditions for yeasts. In this study, yeasts were isolated from fermented orange juice and subjected ... -
Growth Responses of External Hyphae of Arbuscular Mycorrhizal Fungi to Acidic Soil Conditions and their Effects on Cowpea Growth
(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 ... -
Horizontal Transfer of the “Popcorn-Effect” Strain of Wolbachia from Drosophila melanogaster to Stomoxys calcitrans
(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 ... -
Hospital Acquired Bacterial Infection in Burns Unit at Cipto Mangunkusumo Hospital, Jakarta
(2007)Burn injury causes mechanical disruption to the skin, which allows environmental microbes to invade the deeper tissues. A prospective study of infections in burn patients has shown that the incidence of hospital acquired ... -
Hydrolysis Methods of Starch for Culture Media of Bacillus sp. BMN14 Producing Biosurfactant Lipopeptide
(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 ... -
