Research ArticleOpen accessIn the keywordsLeaf Surface Bacterial Colonization in Response to Brevicoryne brassicae (L.) Infestation of Brassica chinensis L.Shaon Raychaudhuri, Inga Mewis, Christian UlrichsProblem statement: Epiphytic population is an intrinsic part of the leaf surface. The effect of stress like insect infestation is not well understood. The aim of the study was to determine possible effects of insect infestation on bacteria community. Approach: The leaf surface microbial profile of Brassica rapa ssp. chinensis (L.) was investigated using a culture-dependent approach under normal and … …Current Research in Microbiology, Vol. 1, Issue 2 · 31 May 2011 · 7,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractExtraction Optimization and Antibacterial Property of Total Flavonoids from Zizania Latifolia Bracts and the Effect on Chilled Pork PreservationChen Pan, Shuyi Zhu, Na Niu et al.Zizania latifolia isa widely distributed aquatic vegetable, and its bracts are an agriculturalwaste with a large proportion. In this study, Total Flavonoids of Z. latifoliaBracts (TFZB) were extracted with Ultrasound-Assisted Enzymatic Extraction(UAEE) for the first time, and the extraction process was optimized usingResponse Surface Method (RSM), and compared with other methods. Then, theantibacterial activity of TFZB extracted with optimized UAEE … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 15 Sep 2022 · 6,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractSafe Ulvan Silver Nanoparticles Composite Films for Active Food PackagingHadear Hanie AminProtecting food from the corruption caused by different microbes is a big problem, as we need safe methods for food packaging. In this study, Ulvan (U), edible sulfated polysaccharide extracted from Ulva lactuca, was mediated for the first time non-toxic biosynthesized silver nanoparticles (Ag-NPs) to produce new and safe bio-nanocomposite films called (U/Ag-NPs) films for active food packaging. Ulvan was … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 1 · 28 Jan 2021 · 7,748 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Physical Treatments on the Promotion of Seed Germination in Green and Giant FoxtailsInagaki Hidehiro, Sakakibara TakumiThe difficulty of breaking seed dormancy in Setaria (foxtail) species presents a problem in using them as model plants. In the present study, we observed the structure of the seed coat surface of two Setaria species, the green foxtail (Setaria viridis) and the giant foxtail (Setaria faberi), using an electron microscope. In addition, we tested the effects of physical treatment … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 25 Nov 2020 · 6,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntidiabetic and Antioxidant Potential of Vernonia amygdalina Leaf Extract in Alloxan-Induced Sprague-Dawley RatsFatmawaty Yazid, Nina Bonita Hasanah, Rosmalena et al.The treatment of diabetes mellitus using drug medications have side effects such as weight gain, hypoglycemia, the risk of cardiovascular or all-cause mortality. These limitations have become one reason to use complementary therapy from plant extract, such as Vernonia amygdalina as an antidiabetes. This research aimed to investigate the effect of V. amygdalina leaf extracts as antidiabetic and antioxidant agents … …OnLine Journal of Biological Sciences, Vol. 20, Issue 4 · 23 Nov 2020 · 8,656 accessesView PDFCite
Research ArticleOpen accessIn the abstractApplication of ZnO Nano Rods for the Batch Adsorption of Cr(VI): A Study of Kinetics and IsothermsSushma Kamath, Venu Gopal Vishwakarma Ramanjaneyalu, Susmita KamilaThe present study reports the synthesis of nano Zinc Oxide (ZnO) and its adsorption behaviour. The ZnO obtained by precipitation method were found to be well-defined nano rods arranged like flower. The shape, size and structure of ZnO were characterized from X-Ray Diffraction (XRD), Energy Dispersive X-ray (EDX) and Scanning Electron Microscope (SEM) analysis. These nano rods were utilized for … …American Journal of Applied Sciences, Vol. 16, Issue 3 · 12 Apr 2019 · 8,077 accessesView PDFCite
Research ArticleOpen accessIn the abstractNew Golden Red Sodium Calcium Silicate GlassesWang Cheng-Yu, Wun Nuan-Xin, Ge Yi et al.Traditional golden red glasses were based on K2O-PbO-SiO2 composition system. In this paper, we reported new golden red glasses based on Na2O-CaO-SiO2 system without SnO2 and PbO in them. By using a spectrophotometer and chromamter color difference meter, it was found that the new glasses had similar optical properties to the traditional ones. The diameter of the gold particles in … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 13 Feb 2019 · 7,068 accessesView PDFCite
