Research ArticleOpen accessIn the abstractSynthesis of Coenzyme Q10Suryachandra Rao Ravada, Lakshma Reddy Emani, Machi Raju Garaga et al.Problem statement: CoQ10 is a key compound in ATP synthesis having wide number of health application especially for treating humans suffering from pathophysiological condition. The CoQ10 presently available in the market is solely derived from fermentation process. A commercially viable synthetic process is yet to be realized. Approach: The researchers described a new synthetic route for the preparation of CoQ10 … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 9,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractMedia 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 abstractImprovement of Biohydrogen Production under Increased the Reactor Size by C. acetobutylicum NCIMB 13357Hisham Salem Alshiyab, Mohd Sahaid Kalil, Aidil Abdul Hamid, Wan Mohtar Wan YusoffProblem statement: One of the main factors influenced the bacterial productivity and total yield of hydrogen is the partial pressure of produced gas. A novel solution to enhance the bacterial productivity was through reduction of gas pressure. Approach: Increasing the reactor size showed to enhance the bacterial production of hydrogen. Results: The technique of increasing reactor size resulted to enhance … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Metal Ion Concentrations on Lipid and Gamma Linolenic Acid Production by Cunninghamella sp. 2A1Farhila Muhid, Wan Nazatul Naziah Wan Nawi, Abdul Jalil Abdul Kader et al.The effects of different concentration of MgSO4.7H2O, FeCl3.6H2O, ZnSO4.7H2O, CuSO4.5H2O and MnSO4.5H2O on lipid and GLA production by Cunninghamella sp. 2A1 were studied in submerged culture fermentation. Cultivation was performed in 250 ml conical flask (100ml working volume), at 30°C and 250 rpm agitation for 120h. Mg2+, Fe2+ and Zn2+ have significant effect on lipid accumulation as inclusion of each … …OnLine Journal of Biological Sciences, Vol. 8, Issue 3 · 30 Sep 2008 · 7,440 accessesView PDFCite
Research ArticleOpen accessIn the abstractNutrient Digestibility and Gas Production of Some Tropical Feeds Used in Ruminant Diets Estimated by the in vivo and in vitro Gas Production TechniquesPaya Hamid, Taghizadeh Akbar, Janmohammadi Hossein, Moghadam Gholam AliSome feedstuffs which used in ruminants diet (corn grain, soybean meal, wheat bran and alfalfa) were analyzed for chemical composition, apparent in vivo nutrient digestibility, in vitro fermentation gas production and metabolizable energy. Chemical composition of test feeds differed in nutrient contents. Initially apparent in vivo digestibility of alfalfa nutrients were obtained then digestibility of nutrients for the other test … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,667 accessesView PDFCite
Research ArticleOpen accessIn the abstractUnconventional Approach for Demineralization of Deproteinized Crustacean Shells for Chitin ProductionN.S. Mahmoud, A.E. Ghaly, F. ArabChitin is a versatile environmentally friendly modern material. It has a wide range of applications in areas such as water treatment, pulp and paper, biomedical devices and therapies, cosmetics, membrane technology and biotechnology and food applications. Crustacean waste is the most important chitin source for commercial use. Demineralization is an important step in the chitin purification process from crustacean waste. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 1 · 31 Mar 2007 · 8,799 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Mutagenesis of Streptokinase Producing BacteriaThaer Taleb Abed Abdelghani, Adinarayana Kunamneni, Poluri EllaiahOf 103 β-haemolytic Streptococci (with haemolytic activity) in total were isolated from different samples of blood and biomass from infected throat, 47 isolates exhibited streptokinase (SK) activity. T3, identified as a new variant of Streptococcus equisimilis, was found to be excellent SK producer in submerged fermentation and was selected for strain improvement studies. This strain was mutagenized by UV and … …American Journal of Immunology, Vol. 1, Issue 4 · 31 Dec 2005 · 7,789 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Cellulase from Oil Palm Biomass as Substrate by Solid State BioconversionMd. Z. Alam, Nurdina Muhammad, Mohd E. MahmatSolid state bioconversion (SSB) of lignocellulosic material oil palm biomass (OPB) generated from palm oil industries as waste was conducted by evaluating the enzyme production through filamentous fungus in lab-scale experiment. OPB in the form of empty fruit bunches (EFB) was used as the solid substrate and treated with the fungus Trichoderma harzianum to produce cellulase. The results presented in … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,440 accessesView PDFCite
