Research ArticleOpen accessPhrase in the titleEnzymatic Hydrolysis of Pretreated Kenaf using a Recombinant Xylanase: Effects of Reaction Conditions for Optimum Hemicellulose HydrolysisNur Izyan Wan Azelee, Jamaliah Md Jahim, Ahmad Fauzi Ismail et al.An efficient hemicellulose hydrolysis has now become a crucial step for xylooligosaccharides production for food additives and nutraceuticals industries. In this study, xylanase hydrolysis of pretreated hemicellulosic kenaf (Hibiscus cannabinus) for substantial hemicellulose hydrolysis was demonstrated. Experiments were performed primarily to investigate the effect of several critical reaction conditions towards the enzymatic hydrolysis of the pre-treated kenaf. The effects of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 28 Apr 2016 · 7,816 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,452 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAssessment of Phenotypic Plasticity in Dairy Production Traits of Toggenburg Goat Genotypes Across South African Agro-ecological ZonesMatshebuka Tshepho, Obert Tada, Louis Thobela TyasiThe study evaluated phenotypic plasticity (PP) in reproductive and milk production traits of Toggenburg (TOG) goat genotypes across five South African agro-ecological zones (AEZ) using a longitudinal observational design. Data from 2,417 does representing five genotypes (Founders, CP, Appendix A, Appendix B, and StudBook Proper) were sourced from the Milch Breeders Society of South Africa LOGIX database. Descriptive statistics and … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 25 Nov 2025 · 2,378 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAdipose-Derived Canine Mesenchymal Stem Cells in PLAY® MediaArjun Kulkarni, Bhavana N. V., Teena Mary Thomas et al.In veterinary medicine, stem cell-based therapies present promise for addressing orthopedic and degenerative conditions in canines. Mesenchymal Stem Cells (MSCs) possess unique regenerative, immunomodulatory, and differentiation capabilities. However, their efficacy relies on optimal in-vitro conditions. Prolonged expansion over passages leads to a gradual loss of stem cell traits, highlighting the importance of optimized culture conditions and media supplements. This study … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 13 Jul 2024 · 5,598 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptimization and Molecular Identification of Protease-Producing Thermophilic Bacterial Isolate TUA-26Anthoni Agustien, Mufidhatul Muqarramah, Feskaharny AlamsjahProtease enzymes are used as biocatalysts that can accelerate a reaction. Thermostable enzymes produced by thermophilic bacteria are needed in the industrial field because of their ability to withstand high temperatures. The thermophilic bacterial isolate TUA-26 that produces protease was to analyze the optimum conditions of temperature, pH, agitation, trace elements, carbon sources, and nitrogen sources; the stability of protease … …OnLine Journal of Biological Sciences, Vol. 24, Issue 3 · 6 Apr 2024 · 4,935 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhosphorylation, Characterization, and Antioxidant Activity of Polysaccharides from Flammulina Velutipes ScrapsYingyun Peng, Xue Bai, Hanwen Xu et al.In this study, polysaccharides from Flammulina velutipes Scraps(FVSP) were extracted. The preparation conditions of the Phosphorylated derivativeof FVSP (Ph-FVSP) were optimized based on single experiments and responsesurface analysis. Characterization and antioxidant properties of FVSP andPh-FVSP were investigated. The optimum phosphorylation modification process ofFVSP obtained was as follows: The mass ratio of STPP/STMP was 1:2, the reaction temperature was 70℃, the … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 16 Aug 2022 · 6,007 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImmunological Characteristics of Winter Wheat Lines with Resistance to Rust Diseases in KazakhstanSaltanat Bakytzhanovna Dubekova, Amangeldy Taskalievich Sarbaev, Aikerim Asylbekkyzy Ydyrys et al.The growing spread of particularly dangerous diseases (variations of rust) in the grain-bearing countries raises fears of the harmfulness of phytopathogens increasing. In the years favorable for their development, a sharp decrease in the productivity of the ear and the quality of the grain is observed. The high potential of the pathogen to produce new aggressive disease variations makes most … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 17 Jan 2022 · 5,969 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCoupling Analysis of Thermodynamic Equilibrium of Mass Transfer and Microbial Community Succession in Multiphase System of Dark Tea Solid-State FermentationZhanjun Liu, Jiawei Sun, Taotao Li et al.During the solid-state fermentation of dark tea, the limited material migration, the dynamic evolution of the thermodynamic equilibrium state, and the highly dynamic succession of the microbial community make it difficult to analyze the quality formation mechanism systematically. Traditional research has focused on microbial diversity or sensory quality analysis, lacking a systematic discussion on the regulatory effects of material migration … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,004 accessesView PDF Cite
