摘要：

Clostridium perfringens type C strain CN 5384 produced a higher level of beta toxin in a controlled pH medium containing 1 % glucose, starch, or sucrose than in media with dextrin, fructose, or raffinose.Toxin synthesis was not related to the growth yield. The effect of glucose on beta toxin production by 11 strains was investigated with and without control of the culture pH at 7.5. Strain CN 5386 produced distinctly higher toxin when the pH of the culture was maintained at 7.5, compared with uncontrolled pH. © 1979, Center For Academic Publications Japan. All rights reserved.
