Research ArticleOpen accessEvery word in the titleCyclodextrin Glucanotransferase Activity of Microbial Strains Isolated from Yam-Cultivation Soils in Northwestern BeninCyrille Alode Vodounon, Ténor Dias-Mendel Allode et al.β-Cyclodextrin, an industrially important oligosaccharide, is produced by microbial enzymes such as cyclodextrin glucanotransferase (CGTase). This study investigated ways to optimize the enzymatic activity of CGTase from Bacillus cereus, Bacillus pumilus, Bacillus brevis, and Bacillus subtilis strains isolated from soils in north-western Benin. Cyclization activity of CGTase and the influence of pH, temperature, and metal ions were assessed using conventional … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 21 Sep 2026 · 652 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleDynamic Mathematical Modelling of Reaction Kinetics for Cyclodextrins Production from Different Starch Sources Using Bacillus macerans Cyclodextrin GlucanotransferaseSyahinaz Shahrazi, Suryani Saallah, Mohd Noriznan Mokhtar et al.This study relates to the mathematical modelling of enzymatic production of Cyclodextrins (CDs) by Cyclodextrin Glucanotransferase (CGTase) from Bacillus macerans. The experiments were carried out in batch mode using different starch sources and the results were used to estimate unknown parameters using linearization and dynamic simulation methods. α- and β-CD produced from tapioca were found to give the highest Michaelis-Menten … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 2 · 20 Jun 2013 · 7,909 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAntibacterial Activity of β-Cyclodextrin and 2-Hydroxypropyl-β-Cyclodextrin Trimethoprim ComplexesHsien-Kuo Sun, Madhumathi Seshadri, Scott Lingard et al.Problem statement: Cyclodextrin complexation has previously been shown to improve the solubility and dissolution properties of trimethoprim; however, no report provides an account of the effect cyclodextrin complexation has on the antibacterial activity of this agent. Approach: β-cyclodextrin and 2-hydroxypropyl β-cyclodextrin inclusion complexes of trimethoprim were prepared and confirmed by differential scanning calorimetry and proton nuclear magnetic resonance. The in-vitro … …Current Research in Microbiology, Vol. 2, Issue 1 · 26 Oct 2011 · 14,801 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsKinetics and Adsorption Isotherm of Ibuprofen onto Grafted β-CD/Chitosan PolymerHashem Bany-Aiesh, Raid Banat, Khaldoun Al-Sou’odThe adsorption of the Ibuprofen (Ibu) drug on β-cyclodextrin (β-CD) grafted chitosan polymer was studied under different experimental conditions. The effect of Ibu concentration, mass of β-CD grafted chitosan polymer as adsorbent, contact time, temperature and pH were investigated. Three equilibrium models, Langmuier, Freundlich and Temkin isotherm models were analyzed to evaluate the adsorption isotherms. The adsorption isotherms were best … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 20 Nov 2015 · 7,444 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDIFFERENT APPROACHES TO CRYSTALLIZATION OF MEMBRANE PROTEINSPrakash G. Doiphode, Vivek Pratap SinghCrystallography is more like an art than science. Crystallizing membrane proteins are a big challenge; membrane proteins are present in the cell membrane and serve as cell support. The most important feature of membrane protein is that it contains both hydrophobic and hydrophilic regions on its surface. They are generally much more difficult to study than soluble proteins. The problem … …OnLine Journal of Biological Sciences, Vol. 12, Issue 3 · 18 Dec 2012 · 7,288 accessesView PDF Cite
