Research ArticleOpen accessIn the keywordsSustainable Production Process of Biological Mineral Feed AdditivesAgnieszka Zielińska, Katarzyna Chojnacka, Marjana SimoničProblem statement: This study discussed the problem of accumulation of Zn and Cu in the topsoil as a result of application of mineral feed additives that possess low bioavailability in animal diet. The review considered the production process of mineral feed additives in which a product supplies microelements in highly bioavailable form. Enrichment of natural biomass of edible microalgae with … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 6,946 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUptake and Recovery of Lead by Agarose Gel PolymersAnurag Pandey, Anupam Shukla, Lalitagauri RayProblem statement: The uptake and recovery of lead ions were investigated by using agarose gel polymers. Approach: The experimental results showed that the agarose gel were effective in removing Pb (II) from solution. Biosorption equilibrium was approached within 4 h. Pseudo second-order was applicable to all the sorption data over the entire time range. Results: The sorption data conformed well … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 7,629 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEVALUATION OF BIOMASS, INDIAN JUJUBA SEED (IJS) FOR REMOVAL OF CONGO REDL. Sivaramakrishna, M. Sivasankar Reddy, M. Jagadeesh et al.The present investigation deals with the removal of Congo Red (CR) from aqueous solution by using Indian Jujuba Seed (IJS) as low-cost biosorbent. The effect of pH and size experimental parameters has been investigated using a Batch adsorption technique. Adsorption data were modeled using Langmuir and Freundlich adsorption isotherms. Adsorption kinetics was verified by pseudo-first order, pseudo-second order and intraparticle … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 30 Jun 2014 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the keywordsRemoval of Mercury from chlor-alkali Industry Wastewater using Acetobacter xylinum CelluloseA. Rezaee, J. Derayat, S. B. Mortazavi et al.In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function of pH, adsorbent dose and contact time. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 8,283 accessesView PDFCite
Research ArticleOpen accessIn the abstractHexavalent Chromium Removal by Litchi chinensis Sonn PeelIsmael Acosta-Rodriguez, Rigoberto Martinez-Perez, Juan F. Cardenas-Gonzalez et al.Problem statement: We studied the Chromium (VI) removal capacity in aqueous solution by the litchi peel. Approach: We use the diphenylcarbazide method to evaluate the metal concentration. Results: The highest biosorption of the metal (50 mg L-1) occurs within 6 min, at pH of 1 and 28°C. According to temperature, the highest removal was observed at 40 and 50°C, in … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 1 · 1 Mar 2012 · 8,223 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiofortification of Food with MicroelementsKatarzyna Chojnacka, Marcin Mikulewicz, Jerzy CieplikProblem statement: Recently a particular attention was paid to the issue of microelement hunger, also termed hidden hunger. The problem was of global significance, since was related with the public health and concerns over 2 billion people. Approach: The study discusses the state of the art in the research on food biofortification as the sustainable solution to cope with micronutrient … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 28 Dec 2011 · 8,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of the Adsorption of the Lead (II) by the Nonliving Biomass Spirogyra neglecta (Hasall) KutzingModher A. Hussain, Aishah Salleh, Pozi MilowProblem statement: Conventional techniques for removing dissolved heavy metals are only practical and cost-effective when applied to high strength wastes with heavy metal ion concentrations greater than 100 ppm. The possibility of using a nonliving algal biomass to solve this problem was carried in this study. Lead (II) was used in this study because it had been reported to cause … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 7,802 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Methylene Blue from Aqueous Solution onto a Low-Cost Natural Jordanian TripoliAtef S. ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries. As a result, recent research has focused on the development of cost effective alternatives using various natural sources and industrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues for recovering … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation of Cr(III) ions by Blue Green-alga Spirulina sp. Part II. Mathematical ModelingKatarzyna Chojnacka, Piotr M. WojciechowskiIn the present paper bioaccumulation of Cr(III) ions by blue-green algae Spirulina sp. is discussed. We found that the process consisted of two stages: passive in which Cr(III) ions are bound to the surface of cells, identical with biosorption and active, metabolism-dependent, in which Cr(III) ions are transported into the cellular interior. The passive stage occurs in both living and … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractThermodynamic Profile of Some Heavy Metal Ions Adsorption Onto Biomaterial SurfacesMedhat A. ShakerThe adsorption of Co2+, Zn2+, Pb2+ and Hg2+ onto dried non-living biomass (NB) of different Pseudomonas strains has been investigated in detail. Maximum adsorption of these cations is achieved at optimum pH values from 3.5 to 4.5 to avoid hydrolysis, polymerization and precipitation of metal cations in the treatment solutions. The experimental data obtained at different temperatures were fitted to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,877 accessesView PDFCite
