Research ArticleOpen accessIn the abstractInulinase Production by Penicillium citrinum ESS in Submerged and Solid-State CulturesCynthia Lafuente-Castaneda, Gabriela Martinez, Juan C. Contreras-Esquivel et al.Problem statement: This work reports the Penicillium citrinum ESS strain as a new source of inulinase (2,1-β-D fructanhydrolase, E.C. 3.2.1.7). Approach: The enzyme was produced in both, Solid-State (SSC) and Submerged Culture (SmC) using a basal medium added either with inulin or sucrose (5 gL-1). Results: The culture grew faster in SmC than in SSC with both carbon sources; however, … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 2 · 13 Mar 2012 · 8,394 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Innovative Farm Scale Biogas/Composting Facility for a Sustainable Medium Size Dairy FarmA.E. Ghaly, M. Al HattabApproach: The amount of energy related costs as a portion of the total farm operating cost can be as high as 29% and the continuing increase of the real cost of energy related farm input has been one of the major factors impacting the cost of agricultural production. However, agricultural has the potential of replacing some of the purchased energy … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Jan 2012 · 9,324 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnzymatic Bioconversion of Agave Leaves FiberHydrolysis Using Plackett-Burman DesignMiguel A. Medina-Morales, J. C. Contreras-Esquivel, H. De la Garza-Toledo et al.Problem statement: Biofuels production is becoming a key factor to help decrease pollution levels and the dependency of fossil fuels. Cellulose from lignocellulosic biomass is being used as a source of raw material for biofuels production, specifically bioethanol, so many ways to use it for this purpose are being developed. Approach: Cellulose content and enzymatic depolymerization of cellulose was evaluated … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 2 Nov 2011 · 8,130 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Nitrogen on Growth and Lipid Content of Chlorella pyrenoidosaSubhasha Nigam, Monika Prakash Rai, Rupali SharmaProblem Statement: In today’s scenario, microalgae are widely recognized as a promising source for biofuel production as a renewable source of energy. They are exceedingly rich in oil, which can be converted to biofuel. This paper deals with one of the method to enhance the lipid content in microalgae. Approach: Microalga, Chlorella pyrenoidosa, was grown autotrophically in batch culture and … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 3 · 22 Sep 2011 · 12,293 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Malaysia's Energy System: Some Preliminary ResultsAhmad Mohd. YusofProblem statement: The current dynamic and fragile world energy environment necessitates the development of new energy model that solely caters to analyze Malaysia’s energy scenarios. Approach: The model is a network flow model that traces the flow of energy carriers from its sources (import and mining) through some conversion and transformation processes for the production of energy products to final … …American Journal of Applied Sciences, Vol. 8, Issue 9 · 13 Aug 2011 · 7,256 accessesView PDFCite
Research ArticleOpen accessIn the abstractCellulolytic 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 PDFCite
Research ArticleOpen accessIn the abstractCloning of the Endoglucanase Gene from a Bacillus amyloliquefaciens PSM 3.1 in Escherichia coli Revealed Catalytic Triad Residues Thr-His-GluZeily Nurachman, Sari Dewi Kurniasih, Ferra Puspitawati et al.Problem statement: An Indonesian marine bacterial isolate, Bacillus amyloliquefaciens PSM 3.1 was isolated for hydrolyzing cellulose. A 1500-bp nucleotide fragment was amplified from the chromosomal DNA by the use of primers directed against the conserved sequence of Bacilli endoglucanase genes obtained from GenBank. Approach: The fragment was cloned and expressed in Escherichia coli. Results: The endoglucanase gene (eglII gene) had … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,727 accessesView PDFCite
