Research ArticleOpen accessIn the abstractISOLATION AND CHARACTERIZATION OF BIFENTHRIN CATABOLIZING BACTERIAL STRAIN BACILLUS CIBI FROM SOIL FOR PYRETHROIDS BIODEGRADATIONPreeti Pandey, Geetika Pant, G. SibiPyrethroids are commonly used in most parts of the world and are reported to have potential health risks. Bifenthrin, a third generation pyrethroid used as insecticide has caused potential effect on aquatic life and human health. Bioremediation is a practical approach to reduce pesticide in the environment and reports of microbial degradation of bifenthrin are meagre. This study was aimed … …OnLine Journal of Biological Sciences, Vol. 14, Issue 3 · 15 Sep 2014 · 7,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF REACTION TEMPERATURE AND REACTION TIME ON PRODUCT FROM HYDROTHERMAL TREATMENT OF BIOMASS RESIDUEJakaphong Kongpanya, Kanokorn Hussaro, Sombat TeekasapThailand is facing with problems associated with biomass residue such as palm oil residues (oil palm trunks, oil palm fronds, empty fruit bunches, shells and fibers). Biomass is promising source for the production of an array of energy-related produts including, liquid, solid and gaseous fuels, heat, chemicals electricity and other materials. Therefore, the use of biomass for energy is not … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 2 Jun 2014 · 7,681 accessesView PDFCite
Research ArticleOpen accessIn the abstractNitrification of Urea and Assimilation of Nitrate in Saturated Soils Under Aerobic ConditionsV. V. Ramakrishnan, A. E. GhalyThe aim of this study was to investigate nitrification activity of urea and the assimilation of nitrate in a well aerated soil using perfusion technique with addition of glucose as an energy and carbon source. In this study, urea was rapidly nitrified by the bacteria in the saturated soil but its course of transformation to NO3 was not linear. There … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 6 Nov 2013 · 8,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioremediation of Petroleum Hydrocarbon-Polluted Mangrove Swamps Using Nutrient Formula Produced From Water Hyacint (Eicchornia crassipes)Frank Anayo Orji, Abiye Anthony Ibiene, Phillip O. OkerentugbaLaboratory-scale studies were carried out using a nutrient formula produced from Eicchornia crassipes plant to achieve bioremediation of crude oil impacted mangrove soil. In a 70 day study, the culturable heterotrophic bacterial population of the Eichhornia crassipes recipe increased from 6.26×105 Cfu/g to 2.69×107 Cfu/g. The control set-up had its total culturable bacterial count increased from 5.76×105 Cfu/g to 1.24×106 … …American Journal of Environmental Sciences, Vol. 9, Issue 4 · 28 Aug 2013 · 7,650 accessesView PDFCite
Research ArticleOpen accessIn the abstractSugar Utilization Potential of Micropolyspora Isolated from Extreme EnvironmentA. B. Koli, Prakash Thorat, S. W. KulkarniProblem statement: Waste water of various industries contain large amount of organic compounds which are continuously added in sea via river which causes water pollution. There is need to degrade the organic content to abate water pollution. Approach: To stabilize the organic content in sea water, there was need to search such an organism which was efficient to degrade organic … …OnLine Journal of Biological Sciences, Vol. 12, Issue 1 · 16 Mar 2012 · 7,263 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 abstractIntegrated Electricity Planning Comprise Renewable Energy and Feed-In TariffHo Wai Shin, Haslenda HashimProblem statement: Mitigation of global warming and energy crisis has called upon the need of an efficient tool for electricity planning. This study thus presents an electricity planning tool that incorporates RE with Feed in-Tariff (FiT) for various sources of Renewable Energy (RE) to minimize grid-connected electricity generation cost as well as to satisfy nominal electricity demand and CO2 emission … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 28 Feb 2012 · 8,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Production of Extracellular Alkaline Lipase by an Improved Strain of Pseudomonas aeruginosa MTCC 10,055Deepali Bisht, Santosh Kumar Yadav, Nandan Singh DarmwalProblem statement: Lipases are industrially important enzymes having applications in numerous industries. For easy commercialization it is necessary to produce lipases at industrial level which could be achieved by strain improvement and medium formulation. Approach: In the present study strain improvement of Pseudomonas aeruginosa MTCC 10,055 was done by chemical mutagenesis using mutagen 4-nitroquinoline1-oxide for alkaline lipase production. Different fermentation … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 24 Nov 2011 · 8,767 accessesView PDFCite
