For example, L. plantarum strains CAU1055, which has a strong CLA synthesis ability; AR326, which has strong adhesion; and CCFM242, which is rich in zinc, better relieve symptoms of colitis than other strains (Choi et al., 2019; Wang et al., 2019; Zhai et al., 2019). This evidence concerns the gene SELPLG and colitis.
