Acid precipitation of Clostridium botulinum type C and D toxins from whole culture by addition of ribonucleic acid as a precipitation aid

M Iwasaki et al. Infect Immun. 1978 Feb.

Abstract

The ratios of ribonucleic acid to protein contents of Clostridium botulinum type C, D, and E cultures were lower than those of type A, B, and F cultures. Addition of ribonucleic acid at 0.4 mg/ml to culture satisfactorily aided acid precipitation of type C and D toxins, but not that of type E toxin.
