Mineral neoformation in pore spaces during alteration and weathering of andesitic rocks in humid tropical Indonesia Dedicated to the late Dr. J. Delvigne
(2003)The morphology, chemistry, and mineralogy of minerals newly formed in voids— products of weathering of andesitic rocks—were studied using optical and submicroscopic techniques on thin sections, combined with scanning ... -
Disease Notes Molecular Characterization of Pepper yellow leaf curl Indonesia virus in Leaf Curl and Yellowing Diseased Tomato and Pepper in Indonesia
(2000)Yellowing and leaf curl symptoms were observed in tomato and pepper fields near Bogor, Java, Indonesia in 2000. Samples were collected from one diseased tomato (Lycopersicum esculentum) and three diseased chili pepper ... -
In vitro anti-biofilm activity of macelignan isolated from Myristica fragrans Houtt. against oral primary colonizer bacteria
(2007)In early dental plaque formation, oral primary colonizers such as Streptococcus mutans, Streptococcus sanguis and Actinomyces viscosus are initially attached to the pellicle-coated tooth surface to form a biofilm. The study ... -
The use of dilution rate cycling to stabilise recombinant plasmids in continuous culture of recombinant Saccharomyces cerevisiae
(1995)The use of dilution rate cycling to stabilise multiple copies of recombinant plasmid pLG669-z in continuous culture of recombinant Saccharomyces cerevisiae over different amplitudes and different frequencies of cycling was ... -
Pesticide applications on Java potato fields are ineffective in controlling leafminers, and have antagonistic effects on natural enemies of leafminers
(2005)Abstract In Indonesia a range of insecticides is routinely applied to control agromyzid leafminers. Insecticide applications can reduce parasitism by indigenous parasitoid wasps and also decrease numbers of the predatory ... -
Hydrolytic enzyme activity of Paenibacillus sp. strain B2 and effects of the antagonistic bacterium on cell integrity of two soil-borne pathogenic fungi
(2000)Paenibacillus sp. strain B2, isolated from the mycorrhizosphere of Sorghum bicolor and having an antagonistic activity towards soil-borne fungal pathogens, possessed extracellular cellulolytic, proteolytic, chitinolytic ... -
Survival and Epiphytic Fitness of a Nonpathogenic Mutant of Xanthomonas campestris pv. Glycines
(1999)Xanthomonas campestris pv. glycines is the causal agent of bacterial pustule disease of soybeans. The objective of this work was to construct a nonpathogenic mutant derived from the pathogenic wild-type strain YR32 and to ... -
Valuation of crucial factors for implementing shed-microspore culture of indonesian hot Pepper (Capsicum Annuum L.) cultivars
(2005)A shed-microspore culture protocol was developed in Wageningen for producing doubled haploid plants in several genotypes of Indonesian hot pepper (Capsicum annuum L.). For transfer of technology to Indonesia, three factors ... -
Begomoviruses Associated with Leaf Curl Disease of Tomato in Java, Indonesia
(2005)We report that several begomoviruses are associated with tomato leaf curl disease in Java, Indonesia. Tomato plants with leaf curl symptoms were collected from Bandung (west Java), Purwokerto (central Java), Magelang ... -
In vitro anticandidal activity of xanthorrhizol isolated from Curcuma xanthorrhiza Roxb
(2006)Objectives: Xanthorrhizol, isolated from the methanol extract of Curcuma xanthorrhiza Roxb., was investigated for its anticandidal activity using six Candida species. Methods: The in vitro susceptibility tests for ... -
Effects of an experimental drought on the functioning of a cacao agroforestry system, Sulawesi, Indonesia
(2010)Agroforestry systems may play a critical role in reducing the vulnerability of farmers' livelihood to droughts as tree-based systems provide several mechanisms that can mitigate the impacts from extreme weather events. ... -
In Vitro antimycotic activity of xanthorrhizol isolated from Curcuma xanthorrhiza Roxb. against opportunistic filamentous fungi
(2006)Xanthorrhizol was isolated from the rhizome of Curcuma xanthorrhiza (Zingiberaceae) and its in vitro activity against opportunistic filamentous fungi was evaluated using the NCCLS (M38-A) standard method. Xanthorrhizol was ... -
Contribution of Sink and Source Sizes to Yield Variation among Rice Cultivars
(2003)In order to identify the key factors that arrest yield improvement in rice, we observed fifteen divergent cultivars in a field at Kyoto, Japan in 1995 and 2001 under various nitrogen (N) regimes. The contribution that sink ... -
The effects of first-season strategic and tactical ivermectin treatments on trichostrongylosis in the first- and second-season grazing
(1999)A 2 year study was conducted to evaluate the effects of first-season strategic or tactical treatments with ivermectin on trichostrongylosis in heifer calves in the first and second-season grazing. Three groups of each eight ... -
Use of chlorate as a selective inhibitor to distinguish membrane-bound nitrate reductase (Nar) and periplasmic nitrate reductase (Nap) of dissimilative nitrate reducing bacteria in sediment
(2004)The use of chlorate as a selective inhibitor of dissimilative nitrate reduction was studied using pure cultures of Comamonas testosteroni (a denitrifier) and Klebsiella pneumoniae (a nitrate-ammonifier) isolated from ... -
A Rapid and Highly Efficient Method for Transformation of Sugarcane Callus
(2004)modern sugarcane cultivars have complex genetic characteristics and low fertility that render their genetic improvement through traditional breeding difficult. -
Kraft lignin degradation products for tanning and dyeing of leather
(2005)Kraft lignin degradation by a biomimetic system was investigated, using hemin as a catalyst and hydrogen peroxide as an oxidising agent, which mimics the catalytic mechanism of lignin peroxidase (LiP) to produce phenolic ...
