Oligosaccharides and dietary fibres are non-digestible food ingredients that preferentially stimulate the growth of prebiotic Bifidobacterium and other lactic acid bacteria in the gastro-intestinal tract. Xylooligosaccharides (XOS) provide a plethora of health benefits and can be incorporated into several functional foods. In the recent times, there has been an over emphasis on the microbial co...

In this study, tailored-made citrus pectin-derived compounds were produced through controlled enzymatic and/or chemical modifications of commercial pectin with different degrees methylesterification (DM) and similar average molecular weight (MW). the first treatment, degradation (CP) materials by endo-polygalacturonase (EPG) yielded pectins Mw’s (between 2 60 kDa). Separation identification oli...

Computer analysis of DNA polymerase protein sequences revealed previously unidentified conserved domains that belong to two distinct superfamilies of phosphoesterases. The alpha subunits of bacterial DNA polymerase III and two distinct family X DNA polymerases are shown to contain an N-terminal domain that defines a novel enzymatic superfamily, designated PHP, after polymerase and histidinol ph...

ethylene was polymerized in slurry phase over a ticl4/mg(oc2h5)2 catalyst activated by al(c2h5)3. it was shown experimentally that mass transfer resistance has no effect on polymerization kinetics. after estimation ofthe active site concentration by inhibition method with carbon monoxide, the effects of polymerization temperature, monomer and cocatalyst  oncentrations and hydrogen were investig...

To evaluate the effects of ionic liquids (ILs) on the microstructural features of aliphatic polyesters for biomedical applications, a series of copolymers were synthesized by lipase ring opening polymerization of rac-lactide (rac-LA) and ε-caprolactone (CL). The chemical structures of resulting polymers were characterized by ¹H- and 13C-NMR and the average molecular weight (Mn) and dispersity i...

INTRODUCTION Polyhydroxyalkanoates (PHAs) are produced as a carbon and energy storage material in various bacteria, and have received much attention as biodegradable and biocompatible plastics. PHAs can be produced from renewable carbon sources such as sugars, fatty acids and plant oils by fermentation.1 Poly[(R)-3-hydroxybutyrate], P(3HB), is the most widely studied and best characterized PHA....

This paper presents a label-free biosensor for the detection of single-stranded pathogen DNA through the target-enhanced gelation between gold nanowires (AuNW) and the primer DNAs branched on AuNW. The target DNA enables circularization of the linear DNA template, and the primer DNA is elongated continuously via rolling circle amplification. As a result, in the presence of the target DNA, a mac...
