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 abstractOptimizing Nano-silver Formation by Fusarium oxysporum PTCC 5115 Employing Response Surface MethodologyM. Karbasian, S. M. Atyabi, S. D. Siadat et al.Fusarium oxysporum was grown in medium containing malt, yeast extracts and glucose on shaker at 25±1°C and180 rpm for 96 h. The mycelia were used to convert silver nitrate solution into nano-silver. The bioconversion was optimized through response surface methodology-central composite design .The factors which affected the process were pH, temperature, agitation rate, concentration of silver nitrate, time of reaction … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,631 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosorption of Cr(III) by Microalgae and Macroalgae: Equilibrium of the ProcessIzabela Michalak, Agnieszka Zielinska, Katarzyna Chojnacka, Jan MatulaEquilibrium experiments of chromium(III) biosorption by microalga (Spirulina sp.) and macroalga (Pithophora varia) were investigated in this paper. Influence of the following process parameters was studied: pH, biomass concentration and temperature. The equilibrium of the process was described with Langmuir equation. The model parameters were determined at various process conditions. The best operation conditions for the process were selected: pH … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 8,208 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioaccumulation of Cr(III) ions by Blue-Green alga Spirulina sp. Part I. A Comparison with BiosorptionKatarzyna ChojnackaThe paper presents the results of studies on kinetics and equilibrium of bioaccumulation process of Cr(III) ions by blue-green alga Spirulina sp. Bioaccumulation was described as the process that consists of two stages, passive (identical with biosorption) and active (accumulation inside the cells). The passive stage (similarly as biosorption itself) was found to be quick process and the subsequent active … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,708 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential Strain to Produce Bioprotein from Cheaper Carbon Source: Hope for MillionsParveen Jamal, Md. Zahangir Alam, Nurul UmiBioprotein production is one of the most promising breakthroughs of biotechnological innovations. Due to its increasing demand, the efficient strains, substrate and method must be used for high yield product. In this study, screening of five different cerivisiea, Mucor hiemalis and Thricoderma harzianum, was done for bioprotein production by liquid state bioconversion of wheat flour as a cheaper carbon source. … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 7,810 accessesView PDFCite
Research ArticleOpen accessIn the abstractKinetics of Chromium Sorption on Biomass Fungi from Aqueous SolutionLouhab Krim, Sahmoune Nacer, Goma BilangoThe kinetics of chromium ions sorption from aqueous solution on fungi biomass have been investigated in a batch system. The experimental data were analysed based on an intraparticle diffusion equation and a pseudo-second-order mechanism, in order to predict the constant rate of sorption and the equilibrium capacity with the effect of initial chromium ions concentration, temperature and initial solution pH. … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 7,424 accessesView PDFCite
Research ArticleOpen accessIn the abstractMethyltert-butyl Ether (MTBE) Degradation by a Microbial ConsortiumS. B. Mortazavi, A. Nikpey, A. Rezaee et al.Methyl tert-butyl ether (MTBE) is added to reformulated gasoline to meet the 1990 Clean Air Act directives. Widespread use of MTBE in gasoline has resulted in groundwater contamination. Because of its undesirable effects on drinking water and ecologically harmful effects, MTBE removal has become a public health and environmental concern. In this study, we have isolated a mixed bacterial culture … …American Journal of Environmental Sciences, Vol. 1, Issue 1 · 31 Mar 2005 · 7,004 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Cellulase from Oil Palm Biomass as Substrate by Solid State BioconversionMd. Z. Alam, Nurdina Muhammad, Mohd E. MahmatSolid state bioconversion (SSB) of lignocellulosic material oil palm biomass (OPB) generated from palm oil industries as waste was conducted by evaluating the enzyme production through filamentous fungus in lab-scale experiment. OPB in the form of empty fruit bunches (EFB) was used as the solid substrate and treated with the fungus Trichoderma harzianum to produce cellulase. The results presented in … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,445 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Properties of Biopolymers from Corn Starch with Addition of Microalgae Spirulina platensisJúllia Koury Abreu, Loraynne Coelho Pereira, José Izaquiel Santos da SilvaThe discovery of the environmental impacts caused by petroleum-based polymers has led to the use of natural polymers gaining more and more space. Naturally occurring polymers, also known as biopolymers, are chemical compounds produced by living things or raw materials from renewable energy sources. Their main advantage is decomposition, while polymers from fossil and non-renewable energies can take hundreds of … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 1 · 16 Mar 2023 · 6,032 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Banana, Pineapple and Watermelon Wastes-Substrate: As Consortiums to Remediating Cyanide Polluted SoilFlorence Obiageli Nduka, Samuel Chibuike Ubani, Victor Eshu Okpashi et al.The act of processing cassava for varied food products has come with unguided and wide-spread contamination of cyanide in the environment. The need for effective reduction in cost to enable remediation of cyanide-contaminated sites from cassava mill factories is the purpose of this investigation. This involves bio-stimulation of organic wastes with indigenous microorganisms to degrade cyanide.
