Research ArticleOpen accessEvery word in the titleReaction Kinetics of Versatile Peroxidase for the Degradation of Lignin CompoundsN. Busse, D. Wagner, M. Kraume, P. CzermakThe H2O2-dependent degradation of adlerol by a crude versatile peroxidase from Bjerkandera adusta, a new ligninolytic enzyme, was investigated. Adlerol (1-(3,4-dimethoxyphenyl)-2-(2-methoxyphenoxy)-1,3-propanediol)) is a non phenolic β-O-4 dimer whose structural architecture represents the most abundant unit (50-65%) of the valuable renewable biopolymer lignin. Lignin removel plays a key role in utilizing lignocellulosic biomass in biorefineries. Steady state analyses in the µL … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 4 · 20 Dec 2013 · 9,263 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKinetics of Thin Layer Drying of Poultry ManureA. E. Ghaly, K. N. MacDonaldThe poultry industry is one of the largest and fastest growing sectors of livestock production in the world. The estimated 2010 world flock was over 18 billion birds with a yearly manure output of 22 million tonnes. Storage and disposal of raw poultry manure has become an environmental problem because of the associated air, water and soil pollution. Environmental and … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 9,015 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKinetics 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 accessEvery word in the titleKinetics of Manganese Uptake by Wetland PlantsA.E. Ghaly, A. Snow, M. KamalThe aim of this study was to assess the kinetics of Mn removal by broad-leaved cattail, soft stem bulrush, soft rush and wool grass plants from contaminated wastewater under laboratory conditions. The approach used was based on a first order kinetic model which depended on the initial heavy metal concentration in the wastewater and allowed for the evaluation of the … …American Journal of Applied Sciences, Vol. 5, Issue 10 · 31 Oct 2008 · 7,324 accessesView PDFCite
