An alternative food source for metabolism and longevity studies in Caenorhabditis elegans

Abstract

Beydoun, Choi et al. develop a metabolically inactive food source for C. elegans worms that minimizes the confounding effects of bacterial metabolism on worm metabolism and aging. They find that worms eat and grow well on a paraformaldehyde (PFA)-treated E. coli food source, recommending the use of 0.5% PFA-killed bacteria as a nematode food source for metabolic experiments.
