Research ArticleOpen accessIn the abstractBrevibacillus Thermoruber 9X-GLC, Bacteria Isolated from Hot Compost, Producer of a Beta-Glucosidase Resistant to Glucose InhibitionAlejandro Sosa-Peinado, María Eugenia Hidalgo-Lara, Miguel Ángel Plascencia-Espinosa et al.The thermotolerant strain Brevibacillus thermoruber 9X-GLC produces large amounts of β-D-glucosidase and cellobiohydrolase when grown on cellobiose and avicel. 9X-GLC was isolated from hot compost of sugarcane bagasse and filter mud and selected for its high enzymatic activity from a Bacilli collection of 77 isolates from soils and compost. Culture supernatants and ultrafiltered concentrates from shaken flask cultures of 9X-GLC … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Oct 2017 · 8,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptical and Structure Analysis of ZnO:Al FilmNeilo Marcos Trindade, Michel Chaves, José Roberto Ribeiro Bortoleto et al.ZnO and ZnO:Al are wide-bandgap semiconductors which have many applications, mainly as transparent conducting films. Thin films of these compounds were deposited onto glass and silicon substrates by RF magnetron sputtering for the investigation of structural and optical characteristics. The XRD results show that the films present wurtzite structure. The formation of a polycrystalline film having a preferential crystallographic orientation … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 5 Oct 2017 · 7,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti-Phase Support Vector Regression Soft Sensor for Online Product Quality Prediction in Glutamate Fermentation ProcessRongjian Zheng, Feng PanGlutamate fermentation is inherently nonlinear, multi-phase and an aerobic fermentation process. As long measurement delays and expensive apparatus cost, on-line measurement of the product concentration is not necessarily available. The present fermentation process monitoring and quality prediction involve manual interpretation of highly informative, however, the concentrations of substrates, biomass and products are only low frequency off-line measurements. In this paper, … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 2 · 6 Jun 2017 · 8,067 accessesView PDFCite
Research ArticleOpen accessIn the abstractEucalyptus Gomphocephala: Morphological Characterization and Seed Germination under Influence of Contaminated SoilOuled Seghaier Wided, Abbes Chaabane, Hasnaoui BrahimTo study the impact of soil pollution on plant growth, our work focused on soil polluted by heavy metals. This soil was taken from the municipal landfill of Jendouba (North of Tunisia). We have undertaken to study the morphological behavior of a forest specie “Eucalyptus gomphocephala”. Two treatments are chosen (substrate containing 100% and 50% of soil taken from municipal … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 12 Apr 2017 · 7,499 accessesView PDFCite
Research ArticleOpen accessIn the abstractWeissella cibaria Fungistatic Activity against Fusarium spp. affecting Yellow PitahayaLeidy Johana Valencia-Hernández, Karina López-López, Liliana Serna-CockFungistatic activity of a Lactic-Acid Bacteria (LAB) was assessed in vitro while isolated from its rumen fluid, against Fusarium oxysporum and Fusarium fujikoroi, basal-rot related species in yellow pitahaya. Fed batch was used to reproduce said LAB. Fungistatic activity kinetic tests were performed on the ferment (S1) and on two of the fractions obtained through centrifugation, supernatant (S2) and biomass … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 10 Dec 2016 · 7,978 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhotoelectrochemical Corrosion of GaN/AlGaN-Based p-n StructuresAlexander Usikov, Heikki Helava, Alexey Nikiforov et al.Direct water photoelectrolysis using III-N materials is a promising way for hydrogen production. GaN/AlGaN based p-n structures were used as working electrodes in a photoelectrochemical process to investigate the material etching (corrosion). The structures were grown on sapphire substrates by chloride Hydride Vapor Phase Epitaxy (HVPE). First, the etching process occurs near vertically via channels associated with defects in the … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 31 Jul 2016 · 7,335 accessesView PDFCite
Research ArticleOpen accessIn the abstractGraphene Synthesis by Plasma-Enhanced CVD Growth with EthanolTeresa Campo, María Cotto, Francisco Márquez et al.A modified route to synthesize graphene flakes is proposed using the Chemical Vapor Deposition (CVD) technique, by using copper substrates as supports. The carbon source used was ethanol, the synthesis temperature was 950°C and the pressure was controlled along the whole process. In this CVD synthesis process the incorporation of the carbon source was produced at low pressure and 950°C … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 3 · 27 Jul 2016 · 9,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigating Effects of Water Conditioning on the Adhesion Properties of Crack SealantAhmed Lamarre, Elham H. Fini, Taher M. Abu-LebdehThis paper investigates the effect of water exposure on three different crack sealants commonly used in cold, moderate and hot climates. It is hypothesized that water penetrates into the interface between crack sealant and substrates causing progressive adhesion failure and that the rate of failure varies depending on the sealant’s surface chemistry as relates to its interaction with water molecules … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 14 Mar 2016 · 8,778 accessesView PDFCite
EditorialOpen accessIn the abstractCommentary-How do we Improve Training for Receptor Research?Marilee Ann BenoreThis issue of the American Journal of Biochemistry and Biotechnology features articles about receptor-ligand interactions that are critical to the wellbeing of all living organisms. The importance of the field of receptor research is supported by the large number of articles published in journals, the numerous specialty journals, the international conferences and the percentage of legal drugs on the market … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 8 Dec 2015 · 8,056 accessesView PDFCite
Research ArticleOpen accessIn the abstractInfluence of Cadmium and Glucose on Soil Microbial CommunitiesAliya Gilmullina, Polina Galitskaya, Svetlana SelivanovskayaA laboratory-based simulation of exposure of the soil community in a gray forest soil to cadmium and glucose has been conducted. It was established that while growing in a fertile medium microbial communities isolated from a soil sample contaminated with cadmium have a substantially increased phase of growth delay and there is a reduction in total growth. While analyzing communities … …American Journal of Applied Sciences, Vol. 12, Issue 10 · 6 Nov 2015 · 6,645 accessesView PDFCite
