Abstract

Abstract: The inhibitory effect of Bifidobacterium breve A04 and its intracellular cell-free extracts on DPPH and lipid free radicals in vitro was evaluated with chemical colorimetry. Chemiluminescent method was used to detect the protective effects on the DNA damage. And the reactive oxygen species (ROS) scavenging ability of B. breve A04 and intracellular cell-free extracts was investigated with electron spin resonance (ESR) technique. The results showed that B. breve A04 and its intracellular cell-free extracts possessed a good scavenging potency on ROS and free radicals.

Key words: Bifidobacterium breve, intracellular cell-free extracts, antioxidation, chemical colorimetry, ESR
