FIGURE 3.

Flow diagram indicating the steps of the probiotic filtering protocol proposed by Bletz et al. (2013) that can be improved by omics data and integrative multi-omics analyses at different stages: (A) Integrated multi-omics methods can inform the isolation probiotic candidates, (B) Probiotic candidates can be tested individually or in combination based on omics results, and (C) Omics approaches can track the effect of probiotic bacteria on the host and on the environment. (D) Omics can provide probiotic candidates that can be tested in mucosome assays.
