In the previous paper1), a strain of Rettgerella-like bacteria has been found to produce a substance giving lethal toxicity to mice (by intraperitoneal injection) when it was inoculated in the octopus muscle extract. Fractionation of the toxic substance was carried out by phosphotungustic acid precipitation method according to Vickery-Levenworth. Results obtained may be summarized as follows: As shown in Table 1, the toxic substance was contained in the non-basic, so-called monoamino acid fraction, however, the toxicity of the fraction decreased as compared with that of the original fluid. It was noted that the lethality was recovered when the non-toxic basic fraction was added to the non-basic fraction (see Table 2). These findings may suggest that the basic fraction itself is not poisonous but it enhances the toxicity of the substance contained in the non-basic fraction, and the co-existence of both fractions might be closely associated with the lethal toxicity of the original culture fluid.
