AbstractAls reine Utopie, als Weg in die “Diktatur des Puritanismus” haben drei Wissenschaftler der Kernforschungsanlage in Jülich kürzlich das Ziel bezeichnet, das vornehmlich von den “Grünen” für die nächsten 50 Jahre verfochten wird: die Umrüstung unserer Gesellschaft auf eine “sanfte”

摘要:

AbstractApproximately 50% of either potato or banana granules ingested by rats fed diets containing the starch granules as the main carbohydrate disappeared in the rat bodies with making corrections for starches in feces and in posthumous contents of the gastro‐intestinal tracts. By scanning electron microscopy starch granules isolated from the digestive tracts of rats showed typical patterns of the enzymatic attack, probably those of α‐amylase attack, on their surface layers and inner portions. SEM observations of the cross‐section of a grain of feces of rats fed with diets containing starch granules of banana and potato revealed that damage of starch granules can be observed without the tedious procedure of separating starch granules from

摘要:

AbstractThe radiodepolymerization of starch is studied by means of investigating the variations of intrinsic viscosity and of the rate of water‐soluble products. The experimental results corroborate the theoretical laws proposed in an earlier paper. Special study of watersoluble products shows how the theoretical laws can be used to investigate the chemical functions radioinduced on the chains of dextrin

摘要:

AbstractWater‐insoluble crosslinked starch was reacted with ethylenimine to yield polyethylenimine covalently bonded to the starch. Other products were prepared by reacting crosslinked starch containing 3‐chloro‐2‐hydroxypropyl groups with polyethylenimine. The products were evaluated in removal of heavy metal cations and anions from industrial was

摘要:

AbstractAmberlite IR‐45 resin was used for immobilization of glucoamylase and the factors affecting the binding power of enzyme to resin, pH, buffer concentration and methods used for immobilization were studied and discussed. Also the factors affecting the reaction velocity of immobilized enzyme were in vestigated. The immobilized enzyme has a higher Km value (0.072) and narrow range of optimum temperature (65–70°C) than free enzyme. Optimum pH for immobilized glucoamylase was 5.5–6.5 while it was 4.5 for free

摘要:

AbstractLiquid chromatographic techniques have been developed to provide a fully automated qualitative and quantitative analysis service for an extensive range of neutral mono‐ and oligosaccharides (DP 2 – 15) with on‐line computer calculation of the data. The service is generally available for the analysis of monosaccharide, oligosaccharide, polysaccharides, glycoproteins etc. in solids, solutions and biological fluids. The application of the analytical methods to industrially important starchy materials, i. e. to the analysis of starch hydrolysates for their oligosaccharides spectra, the expression of the (1 6)‐linkage, amylopectin and amylose contents of starches, the analysis of glucose, fructose and psicose in fructose syrups derived from starches, and the indentification of the less usual components of starchy and starch‐like materials (panose, isopanose, maltotriose, isomaltose, isomaltotriose, etc.) are
