Figure 4. Bacterial viability of cecal slurry (CS) following different storage conditions.

Cecal contents from mice were prepared in 15% glycerol and CS samples were stored at −80, −20, and 4°C. Colony formation unit (CFU) was compared one and six weeks later for all storage conditions (A) and up to six months later for samples stored at −80°C (B). Data represent the mean ± standard deviation.
