One of the limitations of aquaculture is the supply of fish meal needed for the aquaculture industry, but the use of plant items instead of fish meal contain anti-nutrients such as non-starch polysaccharides, which is one of the main limitations of using plant items in the diet of carnivorous fish. The present study investigated the in vivo and in vitro enzymes of alpha-amylase, cellulase, xyla...
متن کاملBacillus stearothermophilus. I. Thermal and pH stability of the amylase.
Investigators are agreed (Kneen and Sandstedt, 1946; Myrback and Neumuiller, 1950) that bacterial amylases, except crystalline preparations (Meyer et al., 1947; Bernfeld, 1951), possess a greater thermostability than other alpha-amylases. Although many investigators have studied the heat stability of amylases from various sources, no study has been published comparing the thermal resistance of ...
متن کاملOccurrence of an Affinity Site apart from the Active Site on the Raw-Starch-Digesting but Non-Raw-Starch-Adsorbable Bacillus subtilis 65 alpha-Amylase.
alpha-Cyclodextrin specifically inhibited raw starch digestion by Bacillus subtilis 65 alpha-amylase. The raw starch digestibility and alpha-cyclodextrin-Sepharose 6B adsorbability of this alpha-amylase were simultaneously lost when the specific domain corresponding to the affinity site essential for raw starch digestion was deleted by proteolysis. Occurrence of the affinity site on raw-starch-...
متن کاملPurification and properties of phaseolamin, an inhibitor of alpha-amylase, from the kidney bean, Phaseolus vulgaris.
Kidney beans, Phaseolus vulgaris, contain a proteinaceous inhibitor of alpha-amylase, which we have named phaseolamin. The inhibitor has been purified to homogeneity by conventional protein fractionation methods involving heat treatment, dialysis, and chromatography on DEAE-cellulose, Sephadex G-100, and CM-cellulose. Phaseolamin is specific for animal alpha-amylases, having no activity towards...
