Research ArticleOpen accessIn the abstractAdvances in Menaquinone-7 Production by Bacillus subtilis Natto: Fed-Batch Glycerol AdditionAydin Berenjian, Raja Mahanama, Andrea Talbot et al.Menaquinone-7 was produced by fermentation mainly using Bacillus subtilis species. Due to the low concentration of menaquinone-7 in fermentation processes and the associated expense of recovering the menaquinone-7, it was desirable to improve the fermentation concentration. The aim of this study was to determine the effect of fed-batch glycerol addition in the production of menaquinone-7 during the fermentation of Bacillus … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 10,545 accessesView PDFCite

Research ArticleOpen accessIn the abstractEffect of Some Fermentation Parameters on Ethanol Production from Beet Molasses by Saccharomyces cerevisiae CAIM13Awatif Abid Al-JudaibiProblem Statement: Some component of fermentation medium showed to reduce the Saccharomyces cerivisae production of ethanol. Approach: This study was designed to evaluate the role of some fermentation parameters in affecting ethanol productivity from beet molasses BM by Saccharomyces cerevisiae CAIM13. Results: Increase in cell concentration (inoculums size) of the yeast above 3.6×105 cells/100 mL decreased the ethanol yield. The … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 25 Jun 2011 · 8,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Effects of the Degree of Soil Salinity and the Bio preparation on Productivity of Maize in the Shaulder Irrigated MassifMaksat Nurbaiuly Poshanov, Shakhislam Uzakbaevich Laiskhanov, Zhassulan Maratovich Smanov et al.During the study on the Shaulder irrigated massif, the soil salinity maps with different degrees of salinity were compiled at the large-scale 1:10000 in the GIS environment. It was found that the area of saline soils increases with depth. In the upper 0-20 cm layer, 29% is salted and in the 50-100 cm layer, up to 44% is salted. The … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 11 Feb 2022 · 6,739 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 · 7,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractReaction Kinetics of Versatile Peroxidase for the Degradation of Lignin CompoundsN. Busse, D. Wagner, M. Kraume, P. CzermakThe H2O2-dependent degradation of adlerol by a crude versatile peroxidase from Bjerkandera adusta, a new ligninolytic enzyme, was investigated. Adlerol (1-(3,4-dimethoxyphenyl)-2-(2-methoxyphenoxy)-1,3-propanediol)) is a non phenolic β-O-4 dimer whose structural architecture represents the most abundant unit (50-65%) of the valuable renewable biopolymer lignin. Lignin removel plays a key role in utilizing lignocellulosic biomass in biorefineries. Steady state analyses in the µL … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 9,270 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpiral Wound Reverse Osmosis Membranes for the Recovery of Phenol Compounds-Experimental and Parameter Estimation StudiesG. Srinivasan, S. Sundaramoorthy, D.V.R. MurthyProblem statement: Reverse osmosis is increasingly used as a separation technique in chemical and environmental engineering for the removal of organics and organic pollutants present in waste water. The removal of an organic compound, namely phenol, using a polyamide membrane was investigated in this study. Waste water containing phenol present a serious environmental problem and increasing attention is being given … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 9,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractSALIVARY CARBONIC ANHYDRASE VI, ZINC SULFATE TASTE ACUITY AND FREQUENCY OF ILLNESS: A PILOT STUDYMatthew J. Zdilla, Leah D. StarkeySalivary Carbonic Anhydrase VI (CA6) is a zinc-dependent metalloenzyme which may be important for normal taste function. Though many taste assessment methods exist, the assessment of zinc sulfate taste acuity is a method that has been suggested to have diverse relationships to human health. A double-blinded pilot study was conducted among 21 individuals to analyze the relationships between salivary CA6 … …American Journal of Immunology, Vol. 10, Issue 2 · 8 Jul 2014 · 7,191 accessesView PDFCite
