It was found that the pH value in fish-waste mixed with cereals and their offals which have shown intense antisepticizing power was reduced in the course of storage. If sugars are added to vast mixed with saw-dust which has shown less antisepticizing power, the pH value of their mixtures may also diminished, and increase in the antisepticizing effect may be observed, The antisepticizing effect of cereals and their offals is therefore pursumed to be due to the formation of acids from sugars in them. But as the volatile base nitrogen never increase in quantity in the waste mixed with sugars, in spite of rising of pH value in the final stage of course of storage, the antieepticizing action of sugars should not be regarded to be attributable only to lowering of the pH value, Starch was found to have scarcely any antisepticizing effect at least in the initial course of storage, but at the presence of sugars, it seems to help their action. Cereals and their offals may correspond to the case.
