Research ArticleOpen accessIn the keywordsStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractSystematic Optimization of Ganoderma lucidum Polysaccharide Fermentation: A Guidance for IndustrializationBin Yang, Junhu Kai, Dehui Dai et al.Ganoderma Lucidum Polysaccharide (GLP) is one of the main active components of G. lucidum and a promising prebiotic for various diseases. Maximizing the production of GLP and minimizing the cost is important for the widespread use of GLP in the food/feed and pharmaceutical industries. The purpose of the present study was to optimize the fermentation condition of a single G. … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 30 Jan 2024 · 5,737 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of Antioxidant and Antibacterial Activities of the Polysaccharides from Mycelium and the Culture Medium of Pleurotus Eryngii Strain UN-1Qing Liu, Haodong Wu, Ying Wu et al.Pleurotus eryngii was one of the most precious and ordinary edible mushrooms, and its polysaccharides were the major active substances. In this study, P. eryngii strain UN-1 was cultured in a liquid medium at 25℃ under a shaking of 80 rpm for 7 days. Two crude polysaccharides named CPN and CPNM were obtained from the mycelium of P. eryngii UN-1 … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 19 Jul 2022 · 6,176 accessesView PDFCite
Review ArticleOpen accessIn the abstractSpace ProbesRelly Victoria Virgil PetrescuA space probe is an unmanned space vehicle launched into space to study more or less distant different celestial objects: The Sun, the planets, dwarf planets and small bodies, their satellites, the interplanetary medium or the interstellar medium. A space probe is distinguished from other unmanned spacecraft that remain in Earth orbit. Space probes can take a large number of … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 21 May 2019 · 7,407 accessesView PDFCite
Research ArticleOpen accessIn the abstractMining, Isolation and Identification of Siderophore Synthesis Gene from Brevibacillus brevis GZDF3Miaomiao Sheng, Huake Jia, Xiaomai Tao et al.Objective of this paper is to excavate the siderophore synthesis gene from Brevibacillus brevis GZDF3 and verify its type and antibacterial effects. The method is using genome mining technology to analyze the siderophore synthesis genes and the phylogenetic tree of each synthesis gene was constructed separately. Iron free medium was utilized to induce the synthesis of siderophore and CAS liquid … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 28 Aug 2018 · 10,606 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel 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 abstractEnhancing Astragaloside Production in Astragalus membranaceus through Growth Media and AuxinsYun Ji Park, Jae Kwang Kim, Sang Un ParkThe secondary metabolites of triterpenoid saponins, isoflavonoids and polysaccharides are present in Astragalus membranaceus those are biologically active. Astragalosides are a major group of identified compounds that have various pharmacological properties.
