Saifuddin, Refal HussainProblem statement: Environmental issues such as global warming and recent events throughout the world, including the shortage of petroleum crude oil, the sharp increase in the cost of oil and the political instability of some crude oil producing countries, have demonstrated the vulnerability of the present sources for liquid fuel. These situations have created great demand for ethanol from fermentation … …Journal of Mathematics and Statistics, Vol. 7, Issue 3 · 18 Jul 2011 · 7,903 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsCellulolytic Enzymes Production by Solid State Culture Using Pecan Nut Shell as Substrate and SupportMiguel A. Medina-Morales, José L. Martínez-Hernández, Heliodoro de la Garza, Cristóbal Noé AguilarProblem Statement: Great interest in the use of lignocellulosic biomass is increasing in order to diminish the accumulation of residues, such as pecan nut shells. One of the alternatives is the fungal degradation of these residues. Approach: The capacity of Trichoderma (coded as T1, T2 and T3) strains to produce cellulase and xylonite was evaluated. Results: Pecan nut shell fibers … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 8,027 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHeat-Modeling of Microwave Assisted Epoxidation of Palm Acid OilN. Saifuddin, L. Wei Zhan, K. Xin NingProblem statement: While microwave chemistry could well be the most convenient, rapid and energy-saving way to initiate a chemical reaction, the issues of thermal versus microwave specific effect remain unaddressed. Approach: A three-dimensional Finite Element Model (FEM) was developed to predict temperature profile during the enzymatic epoxidation of palm acid oil using microwave heating. Three-dimensional partial differential equations are formulated … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,678 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsOptimization of α-Glucosidase Inhibitors Recovery from Rainbow Trout Hydrolysate Using GA-BP Neural NetworkYingke Chu, Yanling Dong, Qingfeng Rong et al.To enhance the value of by-products from rainbow trout processing, the inhibition rate of α-glucosidase (AGIR) is used as indicators. Optimization of rainbow trout hydrolysate extraction by comparing Response Surface Methodology (RSM) and BP Neural Network (BPNN) models. The RSM results: the AGIR is 55.02%. BPNN models predicted the optimal extraction conditions: 51℃ for temperature,1:2.3 for solid-liquid ratio, 4.15 h … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 28 Jan 2026 · 1,737 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Effect of Different Functional Microbial Agents on the Biological Characteristics and Rhizosphere Enzyme Activity of Hydroponic CucumberCe Wang, Ouya Zhao, Shiyou Sun et al.This study aims to comprehensively explore the effect of functional microbial agents on healthy soil cultivation and attempt to increase cucumber yield. Three different microbial agents were used for cucumber seedlings by virtue of the hydroponic cultivation method in order to study their effects on enzyme activity and seedling growth and reveal the relationship between rhizosphere enzyme activity and carbon, … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 1 · 24 Mar 2025 · 5,514 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsOptimization of Hydrolysis Conditions for Obtaining Antithrombotic Peptides from Tenebrio Molitor LarvaeFangyuan Chen, Han Jiang, Yini Gan et al.Tenebrio molitor larvae was hydrolyzed by pepsin and trypsin for preparing high antithrombotic activity hydrolysate. The significant variables were selected according to the Plackett-Burman design and further optimized by the Response Surface Methodology (RSM). Four factors, including substrate concentration, pepsin digestion time, pepsin amount and trypsin amount, respectively, influenced significantly on the hydrolysis effectiveness. The best hydrolysis conditions obtained using … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 20 May 2019 · 8,725 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Influence of Trichoderma viride Cellulase Enzyme Concentration on Saccharification of Waste Paper MaterialsKhomotso M. P. Mokatse, M. Alfred Mogale, J. Pieter H. Van WykEnzymatic hydrolysis of lignocellulosic materials is one of the major steps in the commercialization process of converting cellulosic substrates into bio-products. The saccharification of lignocellulosic materials is usually achieved by a synergistic action of an enzyme mixture consisting of multiple cellulase enzymes such as endo-and exo-glucanase, cellobiohydrolase and β-glucosidase with different mode of actions. During the enzymatic hydrolysis of the … …OnLine Journal of Biological Sciences, Vol. 21, Issue 4 · 28 Oct 2021 · 6,458 accessesView PDF Cite
