Probiotics are live microorganisms known as a health promoting bacteria for the host animals. In general, Lactic acid bacteria and Bifidobacteria belong to probiotic microbes, and yeasts and bacilli are also thought be helpful for their hosts when they are administered in adequate amounts. In this study, we investigated the beneficial effect of probiotic bacteria on the nematode C. elegans focusing on enhancement of lifespan and reproduction of host animals. Several Lactic acid bacteria and Bifidobacteria isolated from Korean traditional fermented foods were fed into C. elegans on the NGM plate, and the survival rate and reproduction ratio were subsequently assessed by scoring animals under the stereo microscope. In order to identify whether small molecules or metabolites produced by bacteria have those beneficial healthy functions, the extracts of bacterial culture broth were administered into C. elegans together with their common foods, E. coli OP50. When C. elegans were fed with some of selected probiotic bacteria, body size of animals were enlarged in their adult hoods. Moreover, the digestion of bacterial foods and locomotion of old animals was also improved by the supplementation with probiotics. These results imply that there are many probiotic resources in Korean traditional fermented foods to increase animals’growth and digestion with anti-aging effects.
