Research ArticleOpen accessEvery word in the titleMolecular Evidence for the Association of a Strain of Uganda Variant of East African Cassava Mosaic Virus to Symptom Severity in Cassava (Manihot esculenta Crantz) Fields in TogoK. D. Adjata, E. Muller, M. Peterschmitt et al.Problem statement: This study was carried out to demonstrate that the severity of Cassava Mosaic Disease (CMD) in Togo, is not only influenced by synergism between cassava Begomoviruses in presence, but essentially by recombination between the different Begomoviruses infecting cassava. Approach: Foliar samples presenting typical biological features of Begomoviruses infection were collected from cassava and wild infected plants from different … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 7,416 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApplication of a Serum/Protein-Free Medium for the Growth of Mammalian Cell Lines and High Level Production of Classical, Variant and Very Virulent Strain of Infectious Bursal Disease Virus (IBDV)Ane Franciele Tapparo, Paloma Oliveira Tonietti, Maria CecÍlia R. Luvizotto, Tereza C. CardosoThe aim of this study was to verify the capacity of IBDV strains, Lukert, F52/70 and very virulent Brazilian genotype (G11) to infect and replicate on cell culture maintained without serum or protein supplementation. BHK21 and CER cells were directed adapted to growth under absence of protein and/or fetal bovine serum with addition of 5 µg mL-1 of insulin-like growth … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 2 · 30 Jun 2008 · 7,656 accessesView PDFCite
Research ArticleOpen accessIn the keywordsVariations in Pathogenicity and Molecular Characterization of Infectious Bursal Disease Virus (IBDV) In EgyptMahmoud E. Sedeik, Ashraf M. Awad, Heba Rashed, Wael K. ElfeilInfectious bursal disease consider a vital threat to poultry industry worldwide and It has special potentiality in Egypt as the country become endemic with several clades from avian influenza from both types highly pathogenic (H5N1 and H5N8) and low pathogenic one (H9N2). The Egyptian government depends on the inactivated vaccine strategy to control avian influenza and any infection with IBD … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 18 May 2018 · 8,479 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpact of Organic Ameliorants on Grey Soil FertilityAsanbay Tagaev, Amandyk Kostakov, Sabir MakhmadzhanovThe study aimed to assess the effectiveness of organic-biological ameliorants for restoring the fertility of light grey soils in the Turkestan region of Kazakhstan, which are characterised by low humus content (0.8-1.1%) and high alkalinity (pH 7.9-8.3). The field experiment was conducted on an area of 2304 m2 using four treatment options: control (variant 1 only mineral fertilisers) and three … …OnLine Journal of Biological Sciences, Vol. 26, Issue 3 · 15 Sep 2026 · 693 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of Antagonistic Activity of Two Trichoderma Species New to Kazakhstan Against Soil PathogensYelena Rakhimova, Assem Assylbek, Lyazzat Kyzmetova et al.The high efficiency of representatives of the Trichoderma genus in suppressing a wide range of plant pathogens contributes to the conduct of large-scale research on the search for local strains. The purpose of this study is to characterize the antagonistic activity of two Trichoderma species new to Kazakhstan (T. pararogersonii and T. rossicum) isolated from the rhizosphere of Picea schrenkiana … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 17 Oct 2023 · 4,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhosphate-Solubilizing Salt-Tolerant Bacteria to Support Soybean Growth (Glycine max (L.) Merr.) On Saline SoilsIrina Smirnova, Amankeldi Sadanov, Gul Baimakhanova et al.Phosphorus is one of the important elements of plant nutrition that affect crop productivity. Increasing the availability of phosphorus through the use of microbial inoculants capable of stimulating soybean growth on saline soils is a promising solution to the problem. However, most phosphate-solubilizing bacteria are not capable of the growth and mobilization of phosphates on saline soils. The purpose of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 2 Oct 2023 · 5,821 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlasmid Mediated Tolerance and Removal of Heavy Metals by Enterobacter spBahig El-DeebProblem statement: The role of plasmid in the heavy metal resistance and accumulation by endophytic bacteria was investigated. Approach: The experimental results showed that high level plasmid mediated Cd2+ and Zn2+ resistance in this strain is due to decreased Cd2+ and/or Zn2+ uptake/accumulation by resistance strain. Results: Based on the fact that subsequent plasmid curing experiments demonstrated that the ability … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 8,001 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Mutagenesis of Streptokinase Producing BacteriaThaer Taleb Abed Abdelghani, Adinarayana Kunamneni, Poluri EllaiahOf 103 β-haemolytic Streptococci (with haemolytic activity) in total were isolated from different samples of blood and biomass from infected throat, 47 isolates exhibited streptokinase (SK) activity. T3, identified as a new variant of Streptococcus equisimilis, was found to be excellent SK producer in submerged fermentation and was selected for strain improvement studies. This strain was mutagenized by UV and … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,789 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordA Thermostable α-Amylase Producing Natural Variant of Bacillus spp. Isolated From Soil in IranIraj Rasooli, Shakiba D. A. Astaneh, Hojjat Borna, Kamal A. BarchiniThermophilic processes appear more stable, rapid and less expensive and facilitate reactant activity and product recovery. Amylases have a quarter of the world enzyme market and thermostable a-amylases possess extensive commercial applications. Since little work has been done on strain isolation, growth and enzyme yield optimization, the level of thermophilic enzyme production remains relatively low. Therefore, large scale exploitation of … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,902 accessesView PDFCite
