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 abstractLocalization of the Dissimilatory Arsenate Reductase in Sulfurospirillum Barnesii Strain SeS-3Eman AfkarProblem statement: Sulfurospirillim barnesii strain SeS-3 is one of the recently known bacterial isolates that can obtain energy to support growth by respiring the toxic oxyanions of arsenic and selenium under anaerobic conditions. Approach: The ultimate goal of this investigation is to localize the active sites for the reduction of arsenate arsenite as well as selenate selenite in S. barnesii … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 5 Mar 2012 · 7,910 accessesView PDFCite
Research ArticleOpen accessIn the abstractExogenous Pyocyanin Alters Pseudomonas aeruginosa Susceptibility to CiprofloxacinGary D. Grant, Tian Tian Zhang, Lee S. Gloyne et al.This in vitro cell-based study identified the contributing role of pyocyanin in the resistance of Pseudomonas aeruginosa to ciprofloxacin. Problem statement: P. aeruginosa is the major pathogen in the Cystic Fibrosis (CF) lung with pyocyanin being a critical component of its virulence. Prevalence is high and, once acquired, chronic infection is difficult to eliminate. Ciprofloxacin remains a crucial oral agent … …Current Research in Microbiology, Vol. 1, Issue 1 · 30 Jun 2010 · 8,800 accessesView PDFCite
Research ArticleOpen accessIn the abstractImmune Response and Pasteurella Resistance in Rabbits Fed Diets Containing Various Amounts of Black Cumin SeedsNabiela M. El Bagir, Imtitha T.O. Farah, Safia M.B. Elhag et al.Problem statement: The consumption of black cumin (Nigella sativa) seed has immunomodulatory and anti-bacterial activity, but in rabbits this had not yet been tested. Approach: In the present studies, rabbits were fed diets without or with black cumin seed and antibody production, phagocytotic activity, hypersensitivity and resistance against Pasteurellosis were assessed. Results: Feeding black cumin seed significantly increased serum concentrations … …American Journal of Animal and Veterinary Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 7,526 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncident of Pseudomonas aeruginosa in Post-Operative Wound InfectionHani A. Masaadeh, Adnan S. JaranThe primary aim of this study was to determine the incidents of pseudomonas aeruginosa in post-operative wound infection and its sensitivity pattern to commonly used antibiotics. During a period of six months between February to December, 2005, 115 specimens were collected from King Abdullah University Hospital, Princess Basma Hospital, Princess Badea and Princess Rahma Hospitals. Samples were obtained from the … …American Journal of Infectious Diseases, Vol. 5, Issue 1 · 31 Mar 2009 · 9,984 accessesView PDFCite
Research ArticleOpen accessIn the abstractTrace Metal Effect on Hydrogen Production Using C.acetobutylicumHisham Alshiyab, Mohd Sahaid Kalil, Aidil Abdul Hamid, Wan Mohtar Wan YusoffThis study was carried out to study the effect of trace metal addition for hydrogen production The results show that this bacterial need a selected nutrient with selected concentration. The optimum parameters for cultivation were at initial pH of 7.0 and temperature of 30°C. Trace metal addition to the new medium showed that only iron enhanced the H2 yield. The … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 7,641 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiological Activity of Methyl tert-butyl Ether in Relation to Soil Microorganisms has a Negative Environmental ImpactGholam H.S. BonjarFuel oxygenates are added to gasoline to enhance combustion efficiency of automobiles and reduce air pollution. Methyl tert-butyl ether (MTBE) is the most commonly used oxygenate because of its low cost, high-octane level and ease of blending with gasoline. However, due to its water solubility, high mobility and low biodegradability it leaches in soil subsurface at the speed of groundwater. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical Composition, Antibacterial and in vitro Anti-Inflammatory Potentials of Essential Oils from Different Plant Parts of Moringa oleifera LamGloria Aderonke Otunola, Anthony Jide AfolayanThe chemical constituents, antibacterial, protection against protein denaturation and membrane stabilization activities of essential oils from flowers, leaves, seeds, bark and roots of M. oleifera were investigated. Of the eight bacterial strains tested, only the growths of four strains were inhibited by the essential oils. The oils from the flowers and seeds were the most active with MIC: 1.25 mg/mL … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 3 · 1 Oct 2018 · 10,337 accessesView PDFCite
