By the present author it has been reported that the bacterial decomposition of “kamaboko” occurs not only in the exterior but also in the interior and that in the exterior the decomposition takes place by the action of microorganisms originated from dusts in air.
The present study aims to ascertain how the microorganisms play upon the decomposition in the interiot of “Kamaboko”
From the substanes of the interior of spoiled “Kamaboko” the agar plate culture was carried out by the ordinary methed.
The number of the colonies of microorganisms grown on Petri dishes was shown in the Table 1.
The classification and the identification of all of these microorganisms were made depending upon Bergey's method. The results obtained were as shown in the Table 2.
From the results it is clear that the interior of “kamaboko” is decomposed principally by the action of spore forming bacilli originated from soil. It seems that these bacteria presented in the interior of “kamaboko” are supplied from the refined starch which is one of the raw materials.
