Research ArticleOpen accessEvery word in the titleFormulation and Evaluation of a Selective Medium for Lactic Acid Bacteria-Validation on Some Dairy ProductsBaida Djeghri-Hocine, Messaouda Boukhemis, Abdeltif AmraneProblem statement: Lactic Acid Bacteria (LAB) is characterized by fastidious nutritional requirements leading to the need for complex and rich media to allow growth. Owing to their complex requirements which also varied significantly with species, the formulation of selective media for LAB is difficult. Approach: A culture medium for LAB was previously developed based on deproteinated whey supplemented with yeast … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 9,410 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMedia Improvement for Hydrogen Production Using C. acetobutylicum NCIMB 13357Mohd Sahaid Kalil, Hisham Salem Saleh Alshiyab, Wan Mohtar Wan YusoffProblem statement: Some component of fermentation medium showed to reduce the bacterial production of hydrogen. Approach: Reinforced clostridium medium is a selected medium for Clostridium species. Reformulation this medium regarding hydrogen production may focus on such medium composition that enhance or reduce the bacterial productivity. The optimum pH and temperature for hydrogen production were at initial pH of 7.0 and … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,255 accessesView PDFCite
Research ArticleOpen accessIn the abstractEconomic Evaluation of Streptococcus Pneumoniae Culture MediaVictor Morais, Norma SuárezStreptococcus pneumoniae, a major bacterial pathogen worldwide, requires a complex medium for culture, which complicates harvesting of antigens for vaccine production. Here we present an economic evaluation of factors affecting the production cost of a chemically defined medium for the scale up of fermentation of S. pneumoniae, compared with the most traditional fermentation media. A basic laboratory-scale experiment of 1 … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 2 · 27 May 2016 · 8,374 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnt Colony Optimization for Load Management Based on Load Shifting in the Textile IndustryChaimongkon Chokpanyasuwan, Tika Bunnag, Ratthasak PrommasThe textile industry is a complicated manufacturing industry because it is a fragmented and heterogeneous sector dominated by Small and Medium Enterprises (SMEs). There are various energy-efficiency opportunities that exist in every textile plant. However, even cost-effective options often are not implemented in textile plants mostly because of limited information on how to implement energy-efficiency measures. This paper presents the … …American Journal of Applied Sciences, Vol. 12, Issue 2 · 9 Apr 2015 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractMonomers Release from Dental Composites: Effect of Immersion Media and Photoactivation Light SourceRaquel A.B. da Silva, Talita P. Prates, Driely Barreiros et al.The present study aimed to evaluate qualitatively and quantitatively the products released by composites with different light sources when immersed in distilled water or artificial saliva. Thirty-six samples were obtained from the composites using a silicone matrix. Specimens were divided into 12 groups according to: Composite (Charisma®, FiltekTMSilorane or GC Kalore®), device used for the materials photoactivation (halogen light or … …Current Research in Dentistry, Vol. 5, Issue 1 · 14 Jan 2015 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Production of Extracellular Alkaline Lipase by an Improved Strain of Pseudomonas aeruginosa MTCC 10,055Deepali Bisht, Santosh Kumar Yadav, Nandan Singh DarmwalProblem statement: Lipases are industrially important enzymes having applications in numerous industries. For easy commercialization it is necessary to produce lipases at industrial level which could be achieved by strain improvement and medium formulation. Approach: In the present study strain improvement of Pseudomonas aeruginosa MTCC 10,055 was done by chemical mutagenesis using mutagen 4-nitroquinoline1-oxide for alkaline lipase production. Different fermentation … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 24 Nov 2011 · 8,760 accessesView PDFCite
Research ArticleOpen accessIn the abstractBasal Salt Requirements Differ According to Culture Stage and Cultivar in Date Palm Somatic EmbryogenesisJameel M. Al-KhayriProblem statement: Various media formulations differing in basal salt composition are arbitrary selected to provide essential nutrients for plant in vitro cultures. Evidence suggests that in vitro response to various media formulations varies among genotypes and depends on the culture stage. This study examined the efficacy of five basal salt formulations on callus growth and somatic embryogenesis in date palm … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 1 · 27 May 2011 · 10,156 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Xylanase Fermentation by Recombinant Escherichia coli DH5α in Shake Flask CultureFarliahati Mohd Rusli, Mohd Shamzi Mohamed, Rosfarizan Mohamad et al.Problem statement: Interest in xylanase enzyme application has markedly increased in pulp and paper processing industries. The switch to xylanase-producing recombinant Escherichia coli DH5α pTP510 is seen here as an economic alternative towards higher productivity and easier downstream purification. Modeling of E. coli DH5α growth and enzyme secretion is thus desired for future optimization in fermentation process. Approach: Kinetics of … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 8,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Environmental Parameters on hydrogen Production using Clostridium Saccharoperbutylacetonicum N1-4(ATCC 13564)Walid M. Alalayah, Mohd Sahaid Kalil, Abdul Amir H. Kadhum et al.Problem statement: Hydrogen gas production by Clostridium can be improved by several ways through media formulation, or suitable environment condition. This study was carried out to investigate the environmental factors effects on hydrogen production using Clostridium saccharoperbutylacetonicum N1-4 (ATCC 13564). Approach: The environmental factor studied includes initial substrate concentration, initial medium pH, temperature, sparging nitrogen and addition of Fe2+. Results: … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,775 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Approach of Almost Periodic Lumped Elements Circuits by an Iterative Method Using Auxiliary SourcesMohamed Karim Azizi, Lassaad Latrach, Nathalie Raveu et al.Nowadays, met materials with lumped or distributed elements are emerging and it is necessary to develop new techniques based on the following principles. The approach should be global and have to be formulated according to the existing classic formulations. In fact, the Wave Concept Iterative Process (WCIP) is systematically used in such application. On the other hand, the periodic medium … …American Journal of Applied Sciences, Vol. 10, Issue 11 · 5 Oct 2013 · 6,919 accessesView PDFCite
