Candida albicans is the most frequent fungi in the oral cavity. Approach: The first step for treatment could be done using topical antifungal agents. Nystatine is a choice for mentioned usage but there are some problems in its using including: unfavorite taste, frequency of usage, etc. Finding better replacements is … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 9,968 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Three Bacteria Consortium for the Bioremediation of Crude Petroleum-oil in Contaminated WaterAbdualdaim Mohammed Mukred, Aidil Abd Hamid, Ainon Hamzah, Wan Mohtar Wan YusoffWe have to developed active microbial consortium that could be of higher degradation of crude oil contaminated groundwater, wastewater aeration pond and biopond at the oil refinery Terengganu Malaysia. Among four isolates that showed good growth only three different isolates (Acinetobacter faecalis WD2, Staphylococcus. sp DD3 and Neisseria elongate TDA4.) were selected based on the growth ability and degradation. Significant … …OnLine Journal of Biological Sciences, Vol. 8, Issue 4 · 31 Dec 2008 · 10,133 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Methyl Tert-Butyl Ether (MTBE) Contaminated Water by Using In situ Catalytic and Biological Combined TechniquesA. Nikpay, H. Kazemian, M. SadeghiThe hydrolysis reaction of Methyl Tert-Butyl Ether (MTBE) into biodegradable products was studied on as-synthesized and commercial H-MFI zeolites. The effect of synthesis procedure and SiO2/Al2O3 ratio was investigated. The results obtained were indicated that H-MFI zeolites were effective in MTBE hydrolysis and increasing of the Si/Al ratio promotes the hydrolysis reaction. The amount of produced TBA was always lower … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,634 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerspectives of Solid State Fermentation for Production of Food EnzymesCristobal Noe Aguilar, Gerardo Gutiérrez-Sánchez, PLilia A. rado-Barragán et al.Food industry represents one of the economic sectors where microbial metabolites have found a wide variety of applications. This is the case of some enzymes, such as amylases, cellulases, pectinases and proteases which have played a very important role as food additives. Most of these enzymes have been produced by submerged cultures at industrial level. Many works in the literature … …American Journal of Biochemistry and Biotechnology, Vol. 4, Issue 4 · 31 Dec 2008 · 10,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review on Some Organic Acids Additives as Shelf Life Extenders of Fresh Beef CutsMohamed B. Jamilah, K.A. Abbas, R. Abdul RahmanThis study was aiming to present some approaches by which the shelf life of fresh beef cuts was extended. These approaches were based on using organic acids. Therefore the work was started with highlighting the deterioration of some quality attributes due to spoilage and pathogenic microorganisms. These attributes included colour, flavour and lipid oxidation changes. In a given holding temperature, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,736 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioinhbition of Diarrhogenic Gram-negative Bacteria using the Tukey-HSD TestAdenike A.O. Ogunshe, J.O. OlaomiA variety of probiotics show promise as effective therapies in the control of diarrhoea, however, diets and geographical locations affect probiotic therapy. In this pilot study, four indigenous probiotic candidates, Lactobacillus acidophilus AAOOL4, L. reuteri AAOOCH1, L. plantarum AAOO25NN and L. delbrueckii AAOOT20 were investigated for their in vitro bactericidal effects on bacterial pathogens implicated in infantile diarrhoea using the … …American Journal of Infectious Diseases, Vol. 4, Issue 2 · 30 Jun 2008 · 7,211 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudies On Bioemulsifier Production by Bacillus licheniformis PTCC 1595Gholamreza D. Noudeh, Mohammad H. Moshafi, Payam Khazaeli, Farideh AkefSurfactants are amphipathic molecules which reduce surface and interfacial tensions and widely used in pharmaceutical, cosmetic, food and petroleum industries. Biosurfactants are the structurally diverse group of surface-active molecules synthesized by microorganisms. There are several advantages for biosurfactants in contrast with chemical surfactants, such as lower toxicity; higher biodegradability; better environmental compatibility; higher foaming; high selectivity and specific activity at … …American Journal of Pharmacology and Toxicology, Vol. 2, Issue 4 · 31 Dec 2007 · 7,282 accessesView PDFCite
Research ArticleOpen accessIn the abstractInhibition of Cholesterol Esterification Influences Cytokine Exspression in Lypopolisaccharide-activated P388D1 MacrophagesRosa Rita Bonatesta, Francesca Sanna, Sabrina Uda et al.Several in vivo and in vitro studies have demonstrated the involvement of infectious agents in the development of atherosclerosis. However, the mechanisms by which micro-organisms induce and/or aggravate atherosclerosis, are so far unclear. Accumulation of cholesterol esters and lipid laden cell formation are hallmark of the atherogenesis, however, the possible relationship between cholesterol esterification and the signal-transducing component of LPS … …American Journal of Infectious Diseases, Vol. 3, Issue 3 · 30 Sep 2007 · 7,481 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Assessment and Monitoring of a Permeable Reactive Barrier for the Remediation of a Contaminated SiteValerio Zolla, Rajandrea Sethi, Antonio Di MolfettaThe present study illustrates the long-term monitoring plan carried out in order to investigate the performance of a zero-valent iron permeable reactive barrier (PRB) at a chlorinated solvents’ site. The cleanup intervention has been undertaken at an industrial landfill located near the city of Turin (Italy) and represents the first full-scale application of this technology in Italy. The monitoring plan … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractCurrent Approaches for the Prevention of Surgical Site InfectionsSander Florman, Ronald Lee NicholsSurgical site infections (SSIs) are the most common type of nosocomial infection among surgical patients and are commonly caused by the patients’ own microbial flora. The prevalence of SSI is a major concern because of the associated increase in the incidence of morbidity and mortality, length of hospitalization and cost of care for postoperative patients. Key factors that determine whether … …American Journal of Infectious Diseases, Vol. 3, Issue 1 · 31 Mar 2007 · 7,824 accessesView PDFCite
