Research ArticleOpen accessIn the keywordsIntegrated Supercritical Fluid Extraction and BioprocessingOwen Catchpole, Stephen Tallon, Peter Dyer et al.Supercritical fluids are increasingly being used and promoted at a laboratory and pilot scale to produce high value, natural bioactives from biologically based raw materials. Supercritical CO2 is overwhelmingly the solvent of choice for these operations, but is largely limited to the processing of dry raw materials and the extraction of low polarity, low molecular weight compounds. The use of … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 9,488 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCharacterization of Fructan Content from Stem Juices of Different Varieties of Agave Atrovirens, Traditionally Used for the Production of Pulque. Production of a Sweetening Syrup by Chemical and Enzymatic ProcessingKaren Gott-Bravo, Arnulfo Pluma-Pluma, Victor Eric López-López et al.Agave atrovirens, the hardiest species of Agave in Mexico, thrives in tough, infertile soils and extreme temperatures across a wide range of altitudes, particularly in impoverished rural areas of Central and Northern Mexico. Its potential for agroindustrial use could offer a pathway to social and economic prosperity for many communities. Traditionally, A. atrovirens is tapped for its sap, known as … …American Journal of Agricultural and Biological Sciences, Vol. 19, Issue 1 · 4 Mar 2025 · 7,670 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFruit Bio-Waste Derived Bio-Ethanol Production and Bioelectricity Generation as Renewable EnergyABM Sharif Hossain, Musamm M UddinBio-waste from food industry is a significant component to pollute the environment. Bioproducts like biomaterials, biofuel can be produced from biowaste and pollution can be reduced. The study was conducted to evaluate the quality of bioethanol production and investigate the bioethanol for bioelectricity generation using rambutan fruit biowaste. Bioethanol yield was the highest in 2 days incubation period of fermentation. … …American Journal of Environmental Sciences, Vol. 17, Issue 4 · 7 Sep 2021 · 7,422 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEnzymatic 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 abstractStatus of Soil Microbial Population, Enzymatic Activity and Biomass of Selected Natural, Secondary and Rehabilitated ForestsK. S. Daljit Singh, A. Arifin, O. Radziah et al.Substantial clearance of forests and conversion of forest into various land use types contribute to deterioration of soil fertility and associated nutrients loss. Soils from natural and rehabilitated forest in Chikus Forest Reserve and also enrichment planting forest and secondary forest of Tapah Hill Forest Reserve, Perak, Malaysia were selected in order to assess the influence of land use change … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,803 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMicrowave Assisted Bioethanol Production from Sago Starch by Co-Culturing of Ragi Tapai and Saccharomyces CerevisiaeN. 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 · 7,898 accessesView PDF Cite

Research ArticleOpen accessIn the abstractImmobilization of Lipase from Candida Rugosa on Palm-Based Polyurethane Foam as a Support MaterialRoila Awang, Mohd Rafaei Ghazuli, Mahiran BasriLipase from Candida rugosa was immobilized onto palm-based polyurethane foam (PU), which the polymer was pre-soaked in co-immobilized agent. The activities of PU-immobilized lipase were tested by the esterification reaction of oleic acid and oleyl alcohol in hexane. The PU-immobilized lipase was then characterized in term of its thermal, operational and storage stability. The optimum temperature for native and PU-immobilized … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 7,478 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordBiotransformation Using Recombinant Cmp Sialic Acid Synthetase and α-2, 6-Sialyltran Sferase: Enzymatic Synthesis of SialosidesUlrike Hubl, Cynthia Sun, Shuguang Zhang et al.In this research, we successfully expressed recombinant CMP-sialic Acid Synthetase (CSS) from Neisseria meningitides and 2,6-Sialyltransferase (SAT) from Photobacterium damsela in E. coli BL21(DE3) fermented at a scale of up to 8 litres using individual plasmids pIRL-1 and pIRL-4b, respectively. After cell lysis with BugBuster, enzyme levels of 2U and 22U per litre were produced for CSS and SAT, respectively. … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 4 · 25 Dec 2012 · 8,854 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEnzymatic Synthesis of Palm Alkyl Ester Using Dialkyl Carbonate as an Alkyl DonorsRoila Awang, Choo Yuen MayProblem statement: Though efficient in terms of reaction yield and time, the chemical approach to synthesizing alkyl ester has drawback such as difficulties in the recovery of glycerol and the need for removal of salt residue. On the other hand, biocatalyst allow for synthesis of specific alkyl esters and easy recovery of glycerol. However, the solvent-free alcoholysis, does not give … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,235 accessesView PDF Cite
