Research ArticleOpen accessIn the author namesNattokinase Activity Guided Natto Fermentation Process OptimizationXiaojie Ren, Chao Huang, Xin Shan et al.The natto kinase in natto has obvious thrombolytic effect, has the advantages of low cost, small side effects, long half-life and can be taken orally, so it has attracted much attention. At present, the research on natto kinase in our country mainly focuses on the selection of natto fermentation strains, the optimization of gene expression conditions and the exploration of … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Dec 2021 · 7,159 accessesView PDFCite
Research ArticleOpen accessIn the author namesTranscriptomic Analysis of the Erythritol High-Yielding Mutant Strain Yarrowia lipolytica Y44Xiaojie Ren, Heng Ban, Chao Huang et al.RNA-seq technique was used to analyze the transcriptomics of Yarrowia lipolytica control strain Po1g, an erythritol-producing natural isolate Yarrowia lipolytica Y 22 and an erythritol high-yielding mutant strain Y44 derived from Y 22. Functional annotation of genes and classification of metabolic pathways were carried out to identify Differentially Expressed Genes (DEGs). These DEGs were classified into related metabolic pathways to … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Dec 2021 · 6,119 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordUsing Permeable Reactive Barriers to Remediate Heavy Metal-Contaminated Groundwater through a Laboratory Column ExperimentSomean Yin, Gemunu Herath, Sokchhay Heng, Senajith KalpageRecently, groundwater sources are being polluted by various activities such as agriculture, livestock, decentralized wastewater treatment systems and acid rain. Groundwater can also be polluted by landfill leachate, sewage, mine tailings, non-engineered deep well disposal of liquid waste and seepage from industrial waste lagoons. There are many studies reported contaminated groundwater remediation using Permeable Reactive Barrier systems (PRBs) and many … …American Journal of Environmental Sciences, Vol. 13, Issue 2 · 12 Mar 2017 · 8,765 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSynthesis and Characterization of Silver/Polyvinilpirrolidone (Ag/PVP) Nanoparticles Using Gamma Irradiation TechniquesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng et al.Problem statement: In this study, attempts had been made to synthesize silver (Ag)/Poly Vinylpyrolidone (PVP) nanoparticles by ionizing radiation and at the same time overcoming some of the disadvantages previously reported by other methods such as impurities, solvent toxicity, size and distribution control and difficulty in their preparation that limits their commercialization potential. Approach: The use of this alternative method … …American Journal of Applied Sciences, Vol. 7, Issue 7 · 31 Jul 2010 · 9,973 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGamma Irradiation Synthesis and Influence the Optical and Thermal Properties of Cadmium Sulfide (CdS)/Poly (Vinyl Pyrolidone) NanocompositesShawkat Salameh Gasaymeh, Shahidan Radiman, Lee Yook Heng, Elias SaionProblem statement: Gamma irradiation has been successfully used to prepare a spherical cadmium sulfide CdS/Poly Vinylpyrolidone (PVP) quantum dots nanoparticles with enhancement of their optical band gap energy and thermal properties at room temperature and under ambient pressure. Sodium thiosulfate was used as a sulfur source in an aqueous solution. The formation of lower band gap energy of CdS/PVP nanoparticles … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,465 accessesView PDFCite
