Fig. 2: Growth profiles of B. longum subsp. longum 105-A wild-type, insertional mutants and a complemented strain.

Each strain was cultured in modified MRS medium supplemented with lactose (a)(c) or lactulose (b)(d) as the sole carbon source. OD600nm values were determined at the indicated time points. The presented data are the mean ± SD of at least three independent assays.
