Research ArticleOpen accessIn the keywordsBiological Control of Rice Blast (Magnaporthe oryzae) by use of Streptomyces sindeneusis isolate 263 in GreenhouseM. Ebrahimi Zarandi, G.H. Shahidi Bonjar, F. Padasht Dehkaei et al.Soil Actinomycetes particularly Streptomyces spp. have antagonistic activity against wide range of plant pathogens. In the recent decades they have attracted high interests as biocontrol agents. In search for finding such principles, in vitro suppression of Magnaporthe oryzae the causal agent of rice blast disease was studied by use of Streptomyces sindeneusis isolate 263 in greenhouse. Spray of rice seedling-leaves … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,496 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Inhibitory Substances on Microbiospora Isolated from Soil under Cultivation of Curcuma Longa L.A. P. Kamble, Prakash Thorat, S. W. KulkarniProblem statement: Soil Pollution is major problem because different types of pesticides are used to control plant pest. The residual component of pesticide diffuses into the soil. It is necessary to check whether actinomycetes degrade these components and control the soil pollution. Approach: In Ayurved system of medicine the rhizome portion of Curcuma longa L. was used as an anti-inflammatory … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 16 Mar 2012 · 7,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Nocardiopsis dassonvillei in a Blood Sample from a ChildFlavio Lejbkowicz, Raya Kudinsky, Luisa Samet et al.Nocardiopsis dassonvillei is an environmental aerobic actinomycete producing a funguslike mycelium and aerial hyphae. Here we report the first Nocardiopsis dassonvillei isolated from a blood sample from a 3-year-old child hospitalized with fever, respiratory difficulty and cough. To the best of our knowledge this is the first time this organism has been detected in the BacT/Alert system. This Nocardiopsis was … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 7,284 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Control of Fusarium oxysporum f. sp. melonis, the Causal Agent of Root Rot Disease of Greenhouse Cucurbits in Kerman Province of IranSara Shafii Bafti, Gholam H.S. Bonjar, Sonia Aghighi et al.Antagonistic activity of 178 soil actinomycete isolates was assayed against Fusarium oxysporum f. sp. melonis Schlecht, Emend (Snyde and Hansen) cause of root rot and fusarium wilt of greenhouse cucurbits in Kerman Province, southeast of Iran. From tested isolates, Streptomyces olivaceus (strain 115) showed anti-fusarium activity revealed through screening and bioassays by agar disk and well-diffusion methods. The active strain … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 6,999 accessesView PDFCite
Review ArticleOpen accessIn the abstractA Review: Biodegradation and Applications of Keratin Degrading Microorganisms and Keratinolytic Enzymes, Focusing on Thermophiles and Thermostable Serine ProteasesWirojne Kanoksilapatham, Weeranut IntagunKeratins are hard-degrading fibrous proteins, insoluble in water and organic solvents, often accumulated in nature and major components in feathers, skins, hair, horn, nail, hoof etc., Keratin-degrading microorganisms such as bacteria, archaea, actinomycetes and fungi employ keratinases to attack keratin. Keratinases belonging to subtilisin-like serine proteases were classified based on similarity of amino acid sequences. Keratinolytic thermophilic or hyperthermophilic bacteria … …American Journal of Applied Sciences, Vol. 14, Issue 11 · 10 Nov 2017 · 9,986 accessesView PDFCite
InvestigationOpen accessIn the abstractMeaning of the Oral Hygiene in Children, Due to Atherosclerosis GenerationAnna Wójtowicz-Bujak, Andrzej WolskiResearch focused on association between periodontal diseases and atherosclerosis has been substantial in recent years. It is now well known that chronic inflammation plays an important role in initiation and evolution of atherosclerosis. The bacterial plaque is a key pathology leading to periodontal inflammation. As reported by other authors, bacteria causing periodontal disease were found within the carotid arteries in … …American Journal of Infectious Diseases, Vol. 11, Issue 4 · 7 Nov 2015 · 7,205 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnti-Oxidant and Enzyme-Inhibitory Potential of Marine StreptomycesT. Revathy, M. A. Jayasri, K. SuthindhiranMarine actinomycetes are potential source for the discovery of novel compounds and enzymes. Though extensive research on marine actinomycetes is underway globally, the actinomycetes research from Indian marine ecosystem is unexplored and understudied. Hence, the present research is focussed on the screening of bioactive compounds from marine actinomycetes isolated from Indian coastal region. This study is designed to determine the … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,242 accessesView PDFCite
