Research ArticleOpen accessIn the abstractInvestigation of the Photoheterotrophic Hydrogen Production of Rhodobacter sphaeroides KCTC 1434 using Volatile Fatty Acids under Argon and Nitrogen HeadspaceRuby Lynn G. Ventura, Jey-R S. Ventura, Young-Sook OhIn this study, the photo fermentative H2 production of Rhodobacter sphaeroides KCTC 1434 was investigated using acetate, propionate and butyrate under argon and nitrogen headspace gases. The highest H2 yield and Substrate Conversion Efficiency (SCE) were observed from butyrate (8.84 mol H2/mol butyrate consumed, 88.42% SCE) and propionate (6.10 mol H2/mol propionate consumed, 87.16% SCE) under Ar headspace. Utilization of … …American Journal of Environmental Sciences, Vol. 12, Issue 6 · 30 Nov 2016 · 9,058 accessesView PDFCite
Research ArticleOpen accessIn the abstractPathologies of Acute Interstitial Pneumonia in Feedlot CattleJose A. Valles, Michael D. Apley, Chris D. Reinhardt et al.Acute Interstitial Pneumonia (AIP) is a costly issue that affects feedlot cattle. Research has yet to elucidate the etiology of AIP; therefore a case-control study was conducted to evaluate possible management and physiological factors that contribute to AIP in feedlot cattle. The experiment was conducted during the summer of 2011 in a commercial feedyard in Kansas. Animals exhibiting clinical signs … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 30 Mar 2016 · 7,896 accessesView PDFCite
Research ArticleOpen accessIn the abstractEFFECT OF WITH/WITHOUT AGITATIONOF AGRICULTURAL WASTE ON BIOGAS PRODUCTION FROM ANAEROBIC CO-DIGESTION-A SMALL SCALENaphon Keanoi, KanokornHussaro, Sombat TeekasapThe growing worldwide concerns over environment, health and monetary aspects have triggered a search for efficient and economic renewable sources of energy production. Agricultural sector holds the potential for development of one of the major source of renewable energy such as biogas. In this study, CSTR-small scale fermentation (200 L stainless steel) was studied to observe the effect of stirring … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 4 Mar 2014 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effect of Natural Water with Cow Dung and Agricultural Waste Ratio on Biogas Production from Anaerobic Co-DigestionNaponKeanoi, KanokornHussaro, Sombat TeekasapGlobal warming caused by energy generation from fossil fuel has accelerated the deployment of renewable fuels such as biogas. In this study, batch fermentation (5L) was studied to observe the effect of natural water, cow dung, rice straw and water hyacinth ratio on the biogas and methane production at ambient temperature (31°C), 7.1-7.4 of pH for 52 days. The five … …American Journal of Environmental Sciences, Vol. 9, Issue 6 · 22 Jan 2014 · 8,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractIdentification of Pseudozyma hubeiensis Y10BS025 as a Potent Producer of Glycolipid Biosurfactant Mannosylerythritol lipidsMartha Sari, Atit Kanti, I. Made Artika, Wien KusharyotoMannosylerythritol Lipids (MEL’s) are glycolipid biosurfactants that contain 4-O-β-D-mannopyranosyl-meso-erythritol as a hydrophilic moiety and fatty acids as a hydrophobic moiety. MEL’s are abundantly produced by several kinds of microorganism and are one of the most promising biosurfactants currently known. The search for a novel endogenous producer of MEL’s was undertaken based on the available collection of the yeast strains from … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 8,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractScreening of Bacteria for Lactic Acid Production from Whey WaterVethakanraj Helen Shiphrah, Sayanti Sahu, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriLactobacilli have the property of converting lactose and other sugars to lactic acid through fermentation. So whey water, the greenish translucent liquid rich in lactose, vitamins, proteins and mineral salts, obtained as a by-product after the precipitation of cheese can be used as a substrate for Lactobacilli for lactic acid production which otherwise is a serious environmental pollutant when disposed … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 9,340 accessesView PDFCite
Research ArticleOpen accessIn the abstractDecolorization of Distillery Effluent by Thermotolerant Bacillus subtilisSoni Tiwari, Rajeeva Gaur, Priyanka Rai, Ashutosh TripathiProblem statement: Ethanol production from sugarcane molasses generate large volume of effluent containing high Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) along with melanoidin, a color compound generally produced by “Millard reaction”. Melanodin is a recalcitrant compound degraded by specific microorganisms having ability to produce mono and di-oxygenases peroxidases, phenoxidases and laccases, are mainly responsible for degradation of … …American Journal of Applied Sciences, Vol. 9, Issue 6 · 14 Mar 2012 · 7,647 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 abstractMeat Spoilage Mechanisms and Preservation Techniques: A Critical ReviewD. Dave, Abdel E. GhalyProblem statement: Extremely perishable meat provides favorable growth condition for various microorganisms. Meat is also very much susceptible to spoilage due to chemical and enzymatic activities. The breakdown of fat, protein and carbohydrates of meat results in the development of off-odors, off-flavor and slim formation which make the meat objectionable for human consumption. It is, therefore, necessary to control meat … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 2 Nov 2011 · 54,798 accessesView PDFCite
