Optimization of medium constituents for Cephalosporin C production using response surface methodology and artificial neural networks
Written by   Published On Issue 3 Vol 1, 2009
Artificial neural networks (ANN) and response surface methodology (RSM) were used to build a model to describe the effects of four independent variables (moisture content, concentrations of glucose, ammonium nitrate and methionine) on the yield of cephalosporin C (CPC) from Acremonium chrysogenum under solid state fermentation. The respective uses of RSM and ANN were found to be effective in locating the optimum conditions within the range fixed from the preliminary runs. When compared with the

Supercritical carbon dioxide (SC-CO2) as a clean technology for palm kernel oil extraction
Written by   Published On Issue 3 Vol 1, 2009
Efforts towards application of Supercritical Carbon Dioxide (SCCO2) extraction in Malaysia are still at its infancy stage. More research has actively on-going to explore its potential performance on a bigger scale (industrial scale) so that it will provide a better alternative method of extraction compare to the present practice using organic solvent extraction. SC-CO2 has been proven on laboratory and pilot-scale as an effective extraction technique for large types of bio-materials such as herb

Application of statistical method to evaluate immobilization variables of trypsin entrapped with sol-gel method
Written by   Published On Issue 3 Vol 1, 2009
Bioimmobilization with sol-gel method is a complicate system, involving many parameters that can affect sol-gel structure and immobilized biomolecules activity. In this study, trypsin, a model enzyme, was entrapped into sol-gel glasses produced from tetraethoxysilane (TEOS) and water to study the relationships between the immobilization parameters, namely ratio of water to TEOS, volume of poly (ethylene glycol) (PEG), concentration of buffer solution, pH of buffer solution by using statistical m

CMP Promoters Database: A systematic study on site-specific transcription factors in CMP genes
Written by   Published On Issue 3 Vol 1, 2009
CMPP Database (Central Metabolic Pathway Promoter Database) consists of manually annotated regulatory sequences/motif of genes controlling Metabolic Pathways (http://cmpp.biodbs.info) such as Glycolysis’ and Krebs’ cycle. The CMPP software package written in Microsoft Visual Basics & MS Access was also developed for searching & updating the CMPP database. This database was further used to study the relationship between 10 transcription factors involved in the non-coding upstream region of CM

Bioinformatics glossary based Database of Biological Databases: DBD
Written by   Published On Issue 3 Vol 1, 2009
Database of Biological/Bioinformatics Databases (DBD) is a collection of 1669 databases and online resources collected from NAR Database Summary Papers (http://www.oxfordjournals.org/nar/database/a/) & Internet search engines. The database has been developed based on 437 keywords (Glossary) available in http://falcon.roswellpark.org/labweb/glossary.html. Keywords with their relevant databases are arranged in alphabetic order which enables quick accession of databases by researchers. Database des
