THERE has been considerable discussion as to the best method to be adopted in isolating the reserve carbohydrate of yeast. In order to isolate the insoluble carbohydrate all other material of the cell must be brought into solution and with this object earlier workers have extracted yeast with solutions of KOH varying from 3 to 60 %. The residue contains the insoluble carbohydrate whilst the sol...

The trypsinized cell walls of Group C streptococci contain two components, the group-specific carbohydrate and a mucopeptide polymer. Hot formamide extraction of Group C cell walls results in a soluble group-specific carbohydrate fraction and an insoluble mucopeptide residue. This mucopeptide, similar in composition to that of Groups A and A-variant streptococci, contains N-acetylglucosamine, N...

Carbohydrate-protein interactions play important biological roles in biological processes. But there is a lack of high-throughput methods to elucidate recognition events between carbohydrates and proteins. This paper reported a convenient and efficient method for preparing oligosaccharide microarrays, wherein the underivatized oligosaccharide probes were efficiently immobilized on aminooxyacety...

Proximate and detergent fiber composition of de-oiled African olive (Canarium schweinfurthii) residue were assessed using standard laboratory analytical procedures. showed 17.58 ± 0.21% crude protein, 4.13 0.06% fat, 19.99 0.89% fiber, 8.11 0.33% ash 50.20 1.19% soluble carbohydrate. Detergent components 54.74±0.0745% NDF, 38.35 0.59% ADF, 14.37 0.68% ADL, 23.98 0.10% cellulose 16.40 0.13% hemi...

Abstract A water-soluble polysaccharide is a part of the soluble food fibers in bengkuang ( Pachyrhizus erosus ). In previous research, it has been carried out by methods fermentation extraction, adding water and precipitation with ethanol on inulin extraction. recent study was examined effect ultrasound-assisted extraction as new method. This research conducted to obtain for chemical propertie...

A silage inoculant [Biomin® BioStabil Plus, BSP, a blend of Enterococcus faecium (DSM 3530), Lactobacillus brevis (DSM 19456) and Lactobacillus plantarum (DSM 19457)], was used on legume-grass silage [32% of dry matter (DM)] vs. an untreated control silage (CT). The material had mean crude protein (CP) and water soluble carbohydrate (WSC) concentrations of 174 and 88 g/kg,respectively. BSP resu...

The increasing commercial production and the broad usage of engineered nanoparticles (ENPs) have led to concerns over the potential adverse impacts of these ENPs on biota in natural environments. Silver nanoparticles (AgNPs) are one of the most important and widely used ENPs which enter natural ecosystems. In this study we examined the effects of AgNPs on growth and some physiological parameter...
