Research ArticleOpen accessIn the abstractMolecular Characterization of Pseudomonas aeruginosa UPM P3 from Oil Palm RhizosphereBadri Fariman Azadeh, Sariah MeonProblem statement: Pseudomonas aeruginosa has been used in agriculture as biological agents. It has shown substantial control of a variety of soil-borne plant pathogens including Macrophomina phaseolina, Botrytis cinerea, Rhizoctonia solani, Colletotrichum truncatum, Pythium, Fusarium and others. Species aggregate of Pseudomonas aeruginosa strain UPM P3 was shown to have potential as a biocontrol agent against Ganoderma boninense, the causal agent … …American Journal of Applied Sciences, Vol. 6, Issue 11 · 30 Nov 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacteristics of a Novel Highly Thermostable and Extremely Thermophilic Alkalitolerant Amylase from Hyperthermophilic Bacillus Strain HUTBS71Farouk Al-Quadan, Hazem Akel, Rasha NatshiProblem statement: This study reported the purification and characterization of a novel highly thermostable alkaline amylase from a newly isolated Bacillus strain HUTBS71. Approach: The enzyme was purified using ammonium sulfate precipitation, ion exchange and gel filtration chromatography. Results: Maximum amylase activity (72 U mL-1) was obtained at 100°C after 10 min of incubation. The enzyme was purified 24 fold … …OnLine Journal of Biological Sciences, Vol. 9, Issue 3 · 30 Sep 2009 · 7,400 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Xylanase Fermentation by Recombinant Escherichia coli DH5α in Shake Flask CultureFarliahati Mohd Rusli, Mohd Shamzi Mohamed, Rosfarizan Mohamad et al.Problem statement: Interest in xylanase enzyme application has markedly increased in pulp and paper processing industries. The switch to xylanase-producing recombinant Escherichia coli DH5α pTP510 is seen here as an economic alternative towards higher productivity and easier downstream purification. Modeling of E. coli DH5α growth and enzyme secretion is thus desired for future optimization in fermentation process. Approach: Kinetics of … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 3 · 30 Sep 2009 · 8,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractCytotoxic and Antimicrobial Potential of Actinomycete Species Saccharopolyspora salina VITSDK4 Isolated from the Bay of Bengal Coast of IndiaK. Suthindhiran, K. KannabiranProblem statement: Although the diversity of marine Actinobacteria have been studied and biotechnologically exploited throughout the world, the studies on marine actinobacteria in Indian peninsula are largely unexplored. Of 9 maritime states in India, only 4 states have been extensively studied for the diversity of actinobacteria. Further, the studies on bioactive actinomycetes from saline soil are very scanty. In the … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 11,440 accessesView PDFCite
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 abstractReview on Landfill Leachate TreatmentsAbdulhussain A. Abbas, Guo Jingsong, Liu Zhi Ping et al.Problem Statement: Sanitary landfilling is the most common way to eliminate solid urban wastes. An important problem associated to landfills is the production of leachates. This study is a review of landfill leachate treatments. Approach: The advantages and disadvantages of the various existing leachate treatments discussed under the items: (i) Leachate channeling (combined treatment with domestic sewage, recycling) (ii) Biological … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 13,754 accessesView PDFCite

NezzalThis present study has for principal objective to treat secondary effluents of the Staoueli purification plant (Algeria) with the average characteristics in the Chemical Oxygen Demand (COD) is 76 mg L-1and 16 NTU of turbidity by adsorption ultrafiltration coupling for its reuse in irrigation or in industry to reduce the water demand. A mineral ultrafiltration tubular membrane of CARBOSEP M2 … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 6,538 accessesView PDFCite
Research ArticleOpen accessIn the abstractTreatment of Wastewater by Natural Lagoon for its Reuse in IrrigationM. Driche, D. Abdessemed, G. NezzalThe process of natural lagoon consists in purifying the waste water by simple flow of the effluent in not very deep ponds where proliferate bacteria, algae and other living organisms, under a surrounding air and in the presence of a solar radiation. For this study, which is spread out over 3 years (2004-2006) and which still continues, we chose the … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnvironmental Impact Assessment for Potential Continuous Processes for the Production of Carbon NanotubesAditi Singh, Helen H. Lou, Ralph W. Pike et al.As an emerging discipline, nanotechnology has the potential to improve environmental sustainability through its application in pollution prevention, treatment, remediation, etc. One challenging issue in the growth of nanotechnology is how to produce purified carbon nanotubes (CNT) in commercial quantities at affordable price and with low environmental impacts.
