Research ArticleOpen accessIn the author namesEffect of Plant Growth Regulators on Callus, Cell Suspension and Cell Line Selection for Flavonoid Production from Pegaga (centella asiatica L. urban)Suat Hian Tan, Radzali Musa, Arbakariya Ariff, Mahmood MaziahProblem statement: Considering pegaga medicinal properties and over-exploitation, the requirement for a tissue culture technique as an alternative production system was crucial. Approach: Investigation of cell suspension culture response to different plant growth regulators (PRGs) for flavonoid production from elite cell line was carried out. Callus cultures were initiated from the leaf explants of Centella asiatica on Murashige and Skoog … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 11,261 accessesView PDFCite
Research ArticleOpen accessIn the author namesCharacterization of Pullulanase Type II from Bacillus cereus H1.5Hii Siew Ling, Tau Chuan Ling, Rosfarizan Mohamad, Arbakariya B. AriffProblem statement: Pullulanase is one of the important enzymes in starch industry. Search for the pullulanase with distinct features, possibly from easily grown bacterium, is of interest for industrial applications Approach: The extracellular pullulanase produced by Bacillus cereus HI.5 was purified by chromatographic method of DEAE-Sepharose, followed by Superdex gel filtration. The enzyme was characterized in terms of the optimal … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 4 · 31 Dec 2009 · 8,813 accessesView PDFCite
Research ArticleOpen accessIn the author namesKinetics 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 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the author namesModeling of Oxygen Transfer Correlations for Stirred Tank Bioreactor Agitated with Atypical Helical Ribbon ImpellerMohd Shamzi Mohamed, Rosfarizan Mohamad, Ramakrishnan Nagasundara Ramanan et al.Problem Statement: Mixing filamentous fungi entails delicate balance between promoting high volumetric oxygen transfer coefficient (kLa) while keeping low hydrodynamic stresses in the microenvironment of cultures. This study examined the oxygen transfer capability of a prototype low shear helical impeller as a potential replacement for the standard Rushton turbine. Approach: The dependence of kLa upon specific power uptake, superficial gas … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 9,169 accessesView PDFCite
Research ArticleOpen accessIn the author namesClassification of Pressure Range Based on the Characterization of Escherichia coli Cell Disruption in High Pressure HomogenizerRamakrishnan Nagasundara Ramanan, Beng Ti Tey, Tau Chuan Ling, Arbakariya B. AriffProblem statement: High pressure Homogenizer was used for cell disruption in many studies. But no work was carried out to study the characteristics of cell disruption in a wide range of pressure. Approach: The characteristics of Escherichia coli cell disruption was studied in Avestin small scale homogenizer by varying the operating pressure (50-1500 bar), cell concentration in the feed (1.39-12.51 … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,632 accessesView PDFCite
