Research ArticleOpen accessEvery word in the titleNovel Production of Two New Nonpolyenic Antifungal Macrolide Derivatives by Streptomyces Z26 Isolated from Moroccan Rhizospheric SoilAhmed Nafis, Brahim Oubaha, Najoua Elhidar et al.The aim of our study was to screen Moroccan actinomycete isolates able to produce nonpolyenic antifungal metabolites in order to contribute to limiting the problem of fungal infections emergence in particular mycotic diseases and to discover known antifungal families, especially nonpolyenic drugs. 480 isolates were tested against 5clinically pathogenic Candida species. Several methods have been used to study the polyenic … …OnLine Journal of Biological Sciences, Vol. 18, Issue 2 · 8 Mar 2018 · 8,459 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiogenic Silver Nanoparticles Produced by Bacteria Isolated from University Campus Environment Soil Samples in Ras Al KhaimahPooja Shivappa, Grisilda Vidya Bernhardt, Sheela Haridas, Michael V MagaogaoSilver is observed to be comprised of a huge percentage ofsilver oxide and the utilization of silver and silver salts is in practicesince ancient human civilization. Silver nanoparticles remain to be potentialantifungal, antibacterial, anti-inflammatory, and antiviral agents. Further, itis demonstrated that silver nanoparticles have been involved in arresting thegrowth of several bacterial species thereby reducing their harmful effects.Micro-organisms are being … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 5 Sep 2022 · 5,870 accessesView PDFCite

Research ArticleOpen accessIn the keywordsIdentification and Characterization of Antibiotic-Producing Actinomycetes IsolatesMeera Kumari, Bat-Erdene Myagmarjav, Birendra Prasad, Madhusudan ChoudharyActinomycetes are a gram-positive, filamentous subgroup of bacteria most known for antibiotic production. In fact, most of the antibiotics available today have originated from actinomycetes, namely from the genus Streptomyces. Novel bacteria with antimicrobial activities have been discovered from bacterial screen studies for decades and there is still much more yet to be unearthed. One hundred seventy five strains of … …Current Research in Microbiology, Vol. 4, Issue 1 · 25 Jun 2013 · 15,437 accessesView PDFCite
Research ArticleOpen accessIn the keywordsBiological Control of Sclerotinia sclerotiorum, Causal Agent of Sunflower Head and Stem Rot Disease, by Use of Soil borne Actinomycetes IsolatesF. Baniasadi, G. H. Shahidi Bonjar, A. Baghizadeh et al.Problem statement: High level of biosafety and non adverse effects on the environment of biocontrol strategies of pest management, are priorities of tomorrow's world agriculture. Actinomycetes are active biocontrol agents due to their antagonistic properties against wide range of plant pathogens particularly fungi. Fungal pathogens are liable for a big part of damages in agriculture economy. Approach: In the present … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 2 · 30 Jun 2009 · 11,166 accessesView PDFCite
Research ArticleOpen accessIn the keywordsHeat Balance Analysis During the Production of Jadomycin CT. J. Burdock, A. H. Giffin, M.S. Brooks, A.E. GhalyJadomycins are novel antibiotics that exhibit biological activity against bacteria and yeast and also demonstrate cytotoxicity against cancer cells. Jadomycin C was successfully produced from 10 L of fermentation media in a 19 L bioreactor using Streptomyces venezuelae ISP5230 which was shocked with ethanol. The bioreactor temperature and pH were successfully maintained at 30°C and 7, respectively. The heat of … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 1 · 31 Mar 2008 · 7,710 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Effect of Various Biopesticides on the useful Arachno Entomofauna of the Apple Orchard in the Southeast of KazakhstanI. I. Temreshev, B. K. Kopzhasarov, Z. B. Beknazarova et al.Currently, Kazakhstan is actively researching the greening of the protection of apple orchards from lepidopteran pests. In this regard, biological preparations of various origins were tested. The aim was to study their impact on useful non-target arachno entomofauna (entomophagous insects and pollinators). During the research, both classical methods used in entomology and plant protection, and original modifications were used.
