Abstract: Provided are a composting accelerator which comprises a mixture obtained by mixing (A) an organic matter having an arabinoxylan content of 10 wt. % or greater and (B) heat-resistant bacteria for assimilating an organic material, and optionally a humic acid and has a pH adjusted within a range of from 6.0 to 8.5; a composting accelerator comprising a mixture obtained by mixing the above-described organic matter (A) and calcium silicate (C) at a weight ratio ranging from 50:50 to 95:5; and a process for producing an organic fertilizer by using each of the above-described composting accelerators.

Abstract: A sustained release composition containing a chemical substance in a matrix. The matrix substantially comprises a hemicellulose extracted from wheat bran under alkaline conditions or a wheat bran extract containing the hemicellulose. The chemical substance is released at a controlled rate from the composition over a long period of time.

Abstract: A new water-insoluble modified gluten product and a new water-soluble proteinaceous substance have now been found to be produced by kneading a mixture of wheat flour, one or more oxidizing agents such as L-ascorbic acid, potassium boromate, ammonium persulfate and potassium iodate, and water and then separating or fractionating the resulting dough-like or batter-like, hydrated flour mixture as kneaded, for instance, by repeated water-washing or centrifugation, so as to give individually a fraction comprising the water-insoluble modified gluten product, a fraction comprising an aqueous solution containing the water-soluble proteinaceous substance dissolved therein, and a fraction comprising the starchy substances and if necessary, subsequently dehydrating said aqueous solution.
