Research ArticleOpen accessPhrase in the titleA Clean-Green Synthesis of Platinum Nanoparticles Utilizing a Pernicious Weed Lantana (Lantana Camara)Musthafa O. Mavukkandy, Sudip Chakraborty, Tasneem Abbasi, Shahid A. AbbasiA rapid, reproducible single step method is proposed for synthesizing platinum nanoparticles using an invasive weed lantana (Lantana camara, L). The method involves mixing of platinum (VI) solution, lantana leaf extract and ascorbic acid in appropriate concentrations and keeping the mixture at 95°C for 8 min. The collective action of ascorbic acid and leaf extract reduced the chloroplatinic acid to … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 23 Feb 2016 · 10,447 accessesView PDF Cite

Research ArticleOpen accessPhrase in the titleGreen Synthesis of Silver Nanoparticles using Extract of Disporopsis Longifolia for Photocatalytic Degradation of Methylene BlueKhieu Thi Tam, Dang Van Thanh, Huu Tap Van et al.In this report, the silver Nanoparticles (AgNPs)were successfully synthesized in a simple one-pot method by the leaf and stemextract of Disporopsis longifolia as reducing, capping agents, andstabilizers for the first time. The optimal extract amount, AgNO3concentration, reaction temperature, and time for the AgNPs synthesis wereidentified using Ultraviolet-Visible (UV-Vis) spectroscopy. X-Ray Diffraction (XRD)and Scanning Electron Microscopy (SEM) were used to characterize … …American Journal of Environmental Sciences, Vol. 18, Issue 5 · 23 Nov 2022 · 6,563 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsBioactivity of Sumac (Rhus Coriaria) Extract as a Green Alternative for Plant Pathogen InhibitionMohammed H. Al-Mamoori, Meisam Zargar, Elena N. Pakina, Fatih DadaşoğluEnvironmental stress caused by pathogenic fungi leads to considerable losses in global crop productivity. Plant-derived extracts are eco-friendly and sustainable alternatives that can inhibit biotic stresses. Sumac (Rhus coriaria) is widely used in industrial and medicinal applications due to its extract rich in secondary metabolites, similar to those found in chemical pesticides and pharmaceuticals. This study aimed to characterize the … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 25 Nov 2025 · 2,209 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsPreparing and Antimicrobial Activity of Hydrogel with Biosynthesized Silver Nanoparticles Using Carex Meyeriana KunthQihui Shen, Henan Zhu, Hongli Zhou et al.In this study, a simple and environmentally stable method was developed to synthesize silver Nanoparticles (AgNPs). In addition, carex meyeriana kunth was used as a reducing and stabilizing agent with good bacterial inhibitory effects against Escherichia coli (E. coli) and Bacillus subtilis at very low doses. AgNPs were added to the Polyvinyl Alcohol (PVA) solution as an antibacterial agent and … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 2 · 4 May 2023 · 5,724 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of three Cutting Ways on the Quality of Fresh-Cut Green Pepper During Room Temperature StorageYue Yang, Shuai Han, Huitao Gao, Hongfang CaiFresh-cut (FC) pepper is favored by consumers all over the world for its convenience, freshness and nutritional value. Previous studies have mostly focused on the influence of preservation approaches on microorganism and quality control of fresh-cut green peppers. Yet, there have been few studies on how the cutting ways affect the quality and antioxidant ability of FC green peppers during … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 22 Aug 2024 · 4,787 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTotal Phenolic Composition and Antioxidant Activity of Silver Nanoparticles using Aqueous Extract of Chilca Leaves (Baccharis latifolia)Fernanda Pilaquinga, Camila Granja, Eliza Jara et al.The importance of studying polyphenols as natural antioxidants has encouraged the search for new methods of rapid, simple analysis.

EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,461 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Efficient Production of Oligosaccharides by a Reaction using Whole Mammalian Cells as BiocatalystsTomohisa Kato, Rie Mitsumori, Kenichi HatanakaProblem statement: Mammalian cells were used for the production of oligosaccharides by saccharide primer method. However, because cells in culture are used, productivity of oligosaccharides is low. Approach: In saccharide primer method employing cells under culture, glycosylation was performed only by mixing the collected cells in reaction mixtures. Saccharide primer, 12-azidododecyl β-lactoside that mimics lactosylceramide (LacCer), was incubated with various … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 6,439 accessesView PDF Cite
