Patent ID: 8735089

Claim:
A method for selecting food grade bacteria with anti-oxidative properties comprising: a a step of synchronizing the growth of Caenorhabditis elegans ( C. elegans ) in the presence of an antibiotic; b a step of feeding the C. elegans on the food grade bacteria to be tested in the presence of an antibiotic; c a step of incubating the C. elegans in the presence of oxidative stress and an antibiotic, and incubating a control group of C. elegans in the absence of oxidative stress as a control and in the presence of an antibiotic; d a step of determining the viability of said C. elegans which were incubated in the presence of oxidative stress and comparing the viability of said C. elegans which were incubated in the presence of oxidative stress to the viability of said control C. elegans worms which were incubated in the absence of oxidative stress; and e a step of selecting the food grade bacteria which provide the highest survival of said C. elegans in the presence of oxidative stress.
