In this study, to test the possibilities of improving polypeptides production, the soybean meal fermentation products were used to investigate the efficiencies of four different novel recombinant engineered A. oryzae strains A. oryzae subC, A. oryzae asp, A. oryzae Ap and A. oryzae pep. Gel filtration was employed … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 1 · 20 Mar 2020 · 7,747 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization for the Extraction of Polysaccharide from Walnut (Juglans regia L.) Leaves: Antioxidant Activities in VitroShuqing Yang, Haifang Xiao, Shuyan Yu et al.Cellulase-assisted extraction of Walnut Leaf Polysaccharide (WLP) was studied. Single factor test and response surface design were employed to optimize the technological conditions. The consequences indicated that the highest WLP yield of 5.21% was achieved with raw material ratio of 50 mL/g, cellulase dose of 41488.52 U/g, enzymolysis pH of 5.88, enzymolysis time of 29.74 min and enzymolysis temperature of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 4 · 23 Oct 2019 · 7,454 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization, Characterization and Antioxidant Activities of Selenized Polysaccharides from Hypsizygus marmoreusTing Liu, Xue Jiang, Wei Wang, Bing XuIn this study, hypsizygus marmoreus was used as raw material to extract polysaccharides by hot water extraction method. Preparation technology of Selenized Polysaccharides from Hypsizygus marmoreus (SPHM) and its antioxidant activities were investigated. Chelation rate was selected as the index, effects of initial concentration of sodium selenite (mg/mL), the mass ratio of polysaccharide to sodium selenite, chelation time and pH … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 8 Aug 2019 · 7,781 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Cellulase-Assisted Extraction of Total Flavonoids from Corn Bract and Evaluation of Antioxidant and Antibacterial AactivitiesYang Zhang, Jing Lu, Leijie Ben et al.Corn bract is a corn-based agricultural waste material that distributed worldwide. In present work, response surface methodology was applied to optimize the cellulase-assisted extraction of Total Flavonoids from Corn Bract (TFCB), the in vitro antioxidant and antibacterial as well as the in vivo antioxidant activities of TFCB were investigated. Results showed that the optimal conditions for TFCB extraction were as … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 18 May 2019 · 8,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractModulation of Aging in Yeast Saccharomyces cerevisiae by Roselle Petal Extract (Hibiscus sabdariffa L.)Sarima, Rika Indri Astuti, Anja MeryandiniCellular aging drives diseases. Free radicals are called the main cause of cellular aging. Antioxidants can protect the body from free radical attack by reducing its negative effects. An antioxidant source can be obtained from plants, such as roselle (Hibiscus sabdariffa. L). This research was conducted to analyze the ability of roselle petals extract to increase the life span of … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 1 · 6 Apr 2019 · 9,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dietary Supplementation of a Mix of Chestnut and Quebracho Tannins on Intestinal Morphology, Bacterial Load, Eimeria spp oocyst Excretion and Immune Response after Vaccination in RabbitsFrancesca Parisi, Simone Mancini, Maurizio Mazzei et al.Among plant products, tannins exhibited a strong antioxidant activity and their employment was studied as food or feed addictive with positive effects. Nevertheless, their health-enhancing properties remain to be completely clarified, particularly in rabbits. The aim of the present study was to investigate the influence of a mix of chestnut and quebracho tannins as supplementation in rabbit diet on intestinal … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 3 · 3 Aug 2018 · 8,630 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Vitamin E on Stress Resorption, Lipid Profile and Reproductive Performance of Sokoto Red GoatsKehinde Matthias OKUKPE, Ling Shing Wong, Geetha Subramaniam et al.Vitamin E (α-tocopherol) plays a critical role in animal nutrition as an antioxidant, contributing to anti-inflammatory responses, immune function, and gene expression regulation.

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,527 accessesView PDFCite
