Abstract

Abstract: The study showed that toxin-producing bacteria were commonly existed in each part of Fugu rubripes body.19 strains of high poisonous bacteria were isolated from its ovary,liver and other tissues,among which,strain B3B was identified as genus Bacillus based on its physiological and biochemical characteristics and 16SrDNA sequence,and could produce tetrodotoxin through mouse test,thinner chromatography,and mass spectrography.

Key words: Fugu rubripes, Microecology, Fermentation products, Tetrodotoxin

CLC Number:

Q938.2
