説明

K-medium is a new type of culture media developed by Katsuya in 1956.^<1)> This inorganic medium is prepared from sodium silicates and phosphoric acid. The advantage of this medium is that it turns to a gelatinous form without heating. In order to evaluate the applicability of K-medium for practical use, growth and ultra structure of Staph. aureus and E. coli grown on this medium were studied comparing with of those grown on Agar-medium. The results obtained are as follows : 1) Number of colonies on K-medium of Staph. aureus and E. coli were significantly increased compared with those on Agar-medium. 2) Ultra structure of Staph. aureus and E. coli cultivated on both media were not differ much from one another. The above results suggest that the K-medium may be useful for detecting contaminations of Staph. aureus and E. coli of foods.
