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 · 5,741 accessesView PDFCite
Research ArticleOpen accessIn the abstractSomatic Embryogenesis of Oil Palm (Elaeis guineensis Jacq.) from Bud Explants Using Suspension CultureNurul Huda Panggabean, Isnaini Nurwahyuni et al.The propagation of oil palm seeds through tissue culture and somatic embryogenesis is a preferred method due to its ability to produce entire plants without the need for gamete fusion. While somatic embryo proliferation is typically performed on solid media, this approach is less efficient than liquid media, which is both more cost-effective and can lead to better proliferation results. … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 4 May 2023 · 5,873 accessesView PDFCite
Research ArticleOpen accessIn the abstractResponse of Root Growth and Root Border Cell Characteristics of Hemerocallis fulva to NaCl StressJinxiu He, Yongxu Qiao et al.Taking three Hemerocallis cultivars ('Jingzhouhua', 'Qingchong', 'Changzuizihua') with different salt tolerance as materials, the effects of 0-200 mmol/L NaCl on root morphology and Root Border Cell (RBC) characteristics were investigated using hydroponic and root suspension culture methods and one-way analysis of variance (ANOVA). The results showed that the root morphology indicators and activity of the high-salt-tolerant 'Jingzhouhua' decreased less than … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 27 Oct 2026 · 80 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Surface Microhardness and Antimicrobial Activity of Conventional and Bioactive Composite Materials for Dental RestorationsBruno Fongaro Dalbosco, Rafael da Silva Vanolli, Poliana Maria de Faveri Cardoso et al.This study evaluated the fluoride release capability, antimicrobial activity, and surface microhardness of bioactive composite resins, critical properties for the effectiveness and durability of dental materials in restorative procedures. Conventional and bioactive composite resins with varying viscosities were tested. Specimens of each resin type were prepared and stored in physiological saline solution for 24 hours to simulate oral conditions. Surface … …Current Research in Dentistry, Vol. 16, Issue 1 · 29 Jan 2026 · 2,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Bacillus Subtilis as Biological Fertilizer by Biotransformation of Corn Steep LiquorXiaojie Ren, Baoyue Liu et al.Corn steep liquor is a kind of intractable organic waste liquidproduced during the processing of corn starch. But it is rich in nutrients,soluble protein, and amino acids and it could be used as a nitrogen source inthe fermentation industry. Many starch processing enterprises cannot directlyutilize corn steep liquor and choose to discharge it directly, thus causingenvironmental pollution. Studies have shown … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 4 · 10 Nov 2022 · 7,391 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Oocyte Retrieval Methods and Maturation Media on in vitro Development of Porcine EmbryosKayla M. Honneysett, Masindi L. Mphaphathi, Edward C. Webb, Ayanda MaqhashuThe objectives of the study were to: Compare oocyte retrieval methods (aspiration and slicing) from pig ovaries on oocyte quality and quantity; compare in vitro maturation (IVM) media (North Carolina State University -NCSU 37; Tissue Culture Medium-TCM 199; and porcine follicular fluid-mpFF) on oocytes polar body extrusion; compare the effect of Electrical Stimulation (ES) and frozen-thawed semen on cleavage rates … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 4 · 5 Jan 2022 · 6,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Evidence for the Role of Natural Radioactivity in Influencing Viability of Commensal MicroorganismsMarco RuggieroTo investigate the feasibility of culturing edible microbes, classified as probiotics for human consumption, in commercially available, naturally radioactive, mineral water; to compare their viability with that of the same microbes cultured in deuterium-depleted water. A diversified array of probiotics was cultured in two different naturally radioactive mineral waters, or in deuterium-depleted water in order to assess the effects of … …American Journal of Immunology, Vol. 17, Issue 1 · 26 May 2021 · 8,745 accessesView PDFCite
Review ArticleOpen accessIn the abstractEffect of Certain Disinfectants and Antibiotics on the Biofilm Formed by Staphylococcus Aureus Isolated from Medical Devices at the University Hospital Center of Sidi Bel Abbes (Algeria)Ibtissem Kara Terki, Hafida Hassaine, Assia Kara Terki et al.Staphylococcus aureus is one of the species that are most frequently isolated from medical devices. The ability to produce a biofilm is an important step in the pathogenesis of these staphylococci; biofilm formation is strongly dependent on the environmental conditions and also on the antibiotics and disinfectants used in the treatment of infections. In this study, 28 staphylococcus aureus isolated … …American Journal of Infectious Diseases, Vol. 15, Issue 3 · 12 Sep 2019 · 7,173 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction, Extraction and Characterization of Lipases from the Antarctic Yeast Guehomyces pullulansLuis Lascano-Demera, Patricia Portero Barahona, Enrique Javier Carvajal BarrigaThe production of extracellular lipases from the Antarctic yeast Guehomyces pullulans is induced using an olive oil medium as an inductor substrate and a first characterization of its enzyme, using the protein extract obtained from the medium, is described. For this, the effect of pH and temperature on the lipase activity are evaluated and the enzyme kinetic for the lipase … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 11 Apr 2019 · 10,031 accessesView PDFCite
